The Architecture Crystal Ball: Predictions for 2012

I have had the opportunity to read several documents containing estimations on what the chief architects and CIOs should expect of the concept of Enterprise Architecture in 2012.

As a result I have made some thoughts of my own, and my thoughts have been delimited to what could happen in Scandinavia. There are reasons for when or where the organization should develop.

Most of the articles that I have read in order to identify the potential development of Enterprise Architecture in 2012 were developed by American organizations and my assumption is that American organizations usually apply an American approach to dealing with problems at hand, and as a result my view might differ quite a bit from the trend analysis that organizations like IBM, Gartner Incorporated, The Open Group, Microsoft or other organizations might have articulated.

Below I have defined four areas that organizations will invest their resources into.

Frameworks and Models

  • CIOs, it-management and the chief architect have discovered that it is unlikely that they will gain a total overview of all systems available in the enterprise and they will focus on developing a few key models.

  • The chief architects will continue investing time and effort into deployment of frameworks, but the chief architects would still have to mix “best of breed” from the frameworks in order to implement the enterprise architecture program.

Investments Planning and Governance

  • Medium and major organizations will begin to add their IT investments to their Enterprise Architecture models, since it is presumable that this would add value to the decision platforms.

  • The investment planning will still be focused on the IT-spending and only to some degree on how information technology takes part of add value to the business.

Technology Foresight

  • The Enterprise Architecture programs will still be IT-centric; however the structured methodology for collecting data about the enterprise architecture will provide the chief architects with the opportunity to impact the IT – strategy, and as such they could have a chance to evolve the enterprise architecture program.

  • The Enterprise Architecture programs will be used in order to define strategic approaches to what sort of technologies that make sense to invest in. As such the chief architect can gain a leading role in articulating the it-strategy. In order to do so the chief architect would enable a platform where realistic scenarios for implementing technology in order to give the decision-makers a realistic insight on what they would have to deal with.

  • The debt and credit crisis will in 2012 impact the organizations in a way that increases the demand for a smarter usage of the information systems and technology platforms available. The smarter usage of information systems demands an approach to information governance and reliable information.

Principles, Standards and Methodology

  • Organizations will find out that without principles for how to deal with different perspectives of developing their IT architecture, they will not be able to enforce the desired behavior. As a result organizations will invest more time in articulating principles.

  • EA assurance for the IT architecture will be a hot topic during 2012, and the organizations will eventually initiate projects that will focus on the articulation of principles based upon criteria like when does the principle apply, when can the developers differ from the principles, when should the principle be updated and who is responsible for updating the standard?

  • Standardization will likewise become a dominant topic, and many organizations will initiate projects that supports the development of it-projects enhances customer experience (platform independent and mobile). Management of standards are vital in order to ensure the development of these projects since it it is vital to ensure the data export of data.

Conclusion

Due to the crisis most organizations tries to reduce costs and deliver a better value proposition to its customers. Most organizations can save money through standardization of the their IT-architecture; however the decision-makers would have to know how to deal with gaining information of how the IT-architecture works, how it can be simplified (enhancing speed of development) and how it can be closer aligned with the business processes.

For this, enterprise architecture is essential and that is how I see the usage of enterprise architecture in Scandinavia in year 2012.

Developing Frameworks: Five Things To Do and Five Things To Avoid.

The Essentials

While working with the concept of Enterprise Architecture it usually becomes a necessity to chose and implement a framework. As such the chief architect can either implement a standard framework, and as such commence the project of documenting the AS – IS situation1. It is an option to adapt the standard framework in order to make it suitable for the enterprise as such make it work better in the implementation process. An alternative to deal with a standard framework the chief architect could develop his or her own framework that from the start has been developed in mind to the specific enterprise. This specific paper is dealing with some pitfalls that I have identified while I have been working with developing a framework by myself.

I will first and foremost outline my definition of what a framework is, then I will deal with which five problems I have encountered and how these problems can be avoided. As such this will become a list of dos and don’ts. Finally I will summarize my findings in a conclusion.

What is a Framework

There are several reasons to apply a framework e.g. the potential of increasing the success rate of the implementation of the Enterprise Architecture program, and as such I have chosen to go in depth with a definition of what I think a framework is about.
I have defined the concept of the Enterprise Architecture framework as essentially a document that outlines which artifacts the chief architect and the Enterprise Architecture group should be identifying, describing and organizing into a repository. Thereto does the framework defines which roles that are supposed to be in the Enterprise Architecture group and how the AS-IS state should be documented. Likewise does the framework details how the scenarios deals with the process of change from the AS – IS situation to a desired TO-BE situation. In between these two it usually a good idea to have a transition plan (Bernard 2005, p. 33).

I have now defined how I understand the concept of the framework. The framework is a key element in order to implement an organized documented overview of the AS – IS situation of the enterprise.

Problems and Solutions

The chief architect should include stakeholders for its internal environment in order to gain an understanding of how they understand the enterprise’s social systems, business systems and information systems. As such the chief architect would have to gain an understanding of how each of the parts of the enterprise works and how these systems interact with one another.

The framework should reflect the organization since it would have to reflect the current conditions yet the framework would have to be used as common reference model for the Enterprise Architecture group. Eventually should the framework be adaptable to filters in order to give the various stakeholders the information that they would need in order to ensure buy-in and support for the changes needed in order to transform the enterprise to the desired state.

While developing the framework the chief architect shouldn’t make the framework too complex in order to the level of details and the language used. Likewise should the chief architect be aware of that the repositories that he choses should be dynamic due to the possible rapid changes in the architecture of the enterprise while the organizational changes are occurring. I am of the opinion that organizations changes more rapidly than the decision makers realizes since people changes habits and their ways to deal with certain tasks due to the changes in their (and thereby the enterprise’s environment). I have come this particular opinion due to an article I have read by Orton and Weick (1990) where Orton & Weick argues that there are several voices of loosely coupling, and one of these voices (the voice of typology) deals with the fragmented environment impacts the possibility to enforce change onto the social systems (Orton & Weick 1990, pp. 207-210) due to connections and impacts of the internal and external environments will in some points stop a centrally planned change.
It is a necessity to avoid rigidity and too much bureaucracy so to say the chief architect would have to avoid creating a paper tiger. It is one of the major problems with Enterprise Architecture , and Wagter et al. (2005, p. 178) discusses in their book titled “Dynamic Enterprise Architecture”. Likewise does Wagter et al. discusses the concept of implementing Enterprise Architecture in small steps and small sections due to the unnecessary usage of the enterprise’s resources in implementing a system in a world where all resources should be contributing to the enterprise’s competitive advantage.

Dos and Don’ts

In order to give the various chief architects or other individuals in the Enterprise Architecture groups in the enterprises out in the industries, I have articulated five things to do order to develop a good framework. Likewise have I articulated a list of five pitfalls that the chief architect or others in the Enterprise Architecture group should avoid in order to implement a successful framework.

Dos

Don’ts

1) Do include stakeholders in the development of the framework.

1) Don’t focus too much on the technical architecture while you develop your framework.

2) Do work with both social systems, business processes and IT.

2) Don’t assume that the framework can be used for a total codification of knowledge in the enterprise.

3) Do work with the business architecture. After all it is the enterprise’s business systems that generates value.

3) Don’t assume that the framework is perfect after you have designed it at the desk. The framework has to be improved during the implementation and after the implementation since new stuff and perspectives will occur.

4) Do work with an approach to keep the framework simple.

4) Don’t assume that people align themselves with a centrally planned strategy. Assume that the organization consists of many different entities that can be impacted by elements outside the organization’s boundary.

5) Do work with the stakeholders understanding of what the framework is and why it is important.

5) Don’t develop a “paper tiger” it makes no sense to develop at lot documents that nobody reads or acts according to.

Which leads to the conclusion of this paper.

Conclusions

A framework is a fundamental element that the chief architect and the decision makers of the enterprise have to be involved with in order to ensure that the Enterprise Architecture program can be implemented in the enterprise. As such there are five things that the chief architect should take into consideration while developing his action plan e.g. Include the stakeholders in the development of the framework, the inclusion of business and IT, the business architecture is the primary architecture, keep the framework simple and ensure that the stakeholders understand what the framework is about and why it is important. Likewise are there five pitfalls that the chief architect has to take into consideration while he develops on the framework e.g. avoid to focus too much on the technical architecture, he shouldn’t assume that the framework is a Swiss army knife in regards to knowledge sharing, he shouldn’t think that the framework is perfect, especially pre-implementation, he shouldn’t believe that people just align themselves with planes developed by a central administration and last but certainly not least. The chief architect shouldn’t develop a paper tiger.

The keyword to framework development is simplicity, prototyping and iterative change.

Week 22 Enterprise Architecture Summer Camp (Day 2)

Posted on
Reply

This blog post deals with the second and final day of the summer school dealing with Enterprise Architecture. The tagline for the summer school is “Scandinavian Design and Oblique Angles”.

The day was characterized as a setup that was dominated by companies and industry professionals who presented topics of a wide variety of topics.

A Next-Generation EA Approach to Modeling the Firm using Capability Sets

John Gotze has in cooperation with Pat Turner written a paper on how to use capability sets in order to make Enterprise Architecture to work, how to sell Enterprise Architecture and what the value of Enterprise Architecture is all about.

The primary problem that the paper is about to answer is what capabilities the enterprise can get and how it can enhance it through shared capabilities.

John Gotze emphasized that one of the problems with the model that Ross and Weill (2006) proposed for Enterprise Architecture is based on that they don’t give a clue on what is their platform for execution and what is a part of the foundation platform.

John Gotze defines a capability as “an Ability or Expertise upon which that the Enterprise relies to fulfill its core functions”. Likewise does Gotze and Turner define an enterprise capability as “A capability that pervades across the whole of the enterprise”.

According to John Gotze, one organization that applies enterprise capabilities, is the U.S. Army. An example could be the tagline “one army”. With this in mind John Gotze made a reference to David A. Clark’s book on world poverty that deals with how to ensure capabilities among other things.

John Gotze later said that a capability set is directly coupled to the execution of the various processes. The second case that John Gotze presented was the Australian Customs and Border Protection Service. The agency should have one of the biggest Enterprise Architecture programs that John Gotze has ever seen and as such they have articulated a five year plan and roadmaps on how to achieve a better architecture.

In order to achieve enterprise capabilities for the enterprise John Gotze and Pat Turner has developed a rather comprehensive framework in order to achieve a better enterprise.

  • A big part of the value of enterprise architecture program can be traced to the capabilities that the program can aid the enterprise with.
  • The paper investigates case studies on how Enterprise Architecture could generate “enterprise capabilities”.
  • An academic investigation of Enterprise Architecture is all about and how “competitive advantages” can be achieved through the implementation of a Enterprise Architecture program.

Vestas Wind Systems – Windy Architectures

The keynote speaker is Troels Fleckenstein who is Vice President at Vestas Wind Systems.

According to the keynote speaker all windmills from Vestas are equipped with technology that enable the windmills to communicate through the Internet with Vestas. Each of the Windmills communicate with Vestas 512 times yearly. This has created a large quantity of data that the corporation has to deal with in order to ensure maintenance of the windmills. Vestas hasn’t an Enterprise Architecture program, or at least that is what the speaker from Vestas said.

The keynote included a video on what Vestas is all about and Ditlev Engel appeared. Apparently Vestas has a slogan that they apply internally that is known as “people before megawatt” that as such means that Vestas doesn’t have HR-department but a department for people and culture (which I presume is pretty much the same). Vestas’ strategy is based upon that they believe they should be number one in wind energy. As such Vestas claims that 1/3 of all windmills sold on a global scale is produced by Vestas.

For Vestas the People’s Republic of China and the Republic of India represents the key markets due to the development of the various enterprises. Most likely are other countries in the BRIC group also of interest to Vestas Wind Systems.

Vestas has 15 locations around the world that develops on new products. Vestas produce nacelles in 15 locations, blades in 7 locations and towers in 2 locations and as such Vestas is able to deliver “Wind Power Plants” in eight regions of the world, or at least that is what the keynote speaker proclaimed.

Vestas’ current strategy is named the triple 15. The current corporate strategy goes to 2015 and they want to achieve a yearly revenue on 15% (currently it is 8.5%) and an EBIT (Earnings before interest and taxes) on 15%.

The keynote speaker presented the Vestas business model as titled it the strategy for empower the corporate strategy. With this approach in mind I am sure that Vestas applies an idea that is compatible with “Cybernetics paradigm”. Furthermore Vestas applies an approach they have titled “The Vestas’ High Five” that entails that energy should be competitive, predictable, independent, fast and clean. According to the keynote speaker the most important partners for Vestas are their customers. In other words Vestas would like to own the means of production of “wind energy” and thereby be able to set the price(s) for producing Windmills.

Vestas’ enterprise architecture team is located within the department for strategy and innovation and this is located in Vestas’ group IT. Apparently Vestas apply a model that includes four perspectives: 1) Innovation, 2) Roadmap, 3) Projects and last but not least 4) System Portfolio.

The Vestas’ Enterprise Architecture program is about “business and value adding activities”, or that is the opinion of the keynote speaker.

When working with enterprise architecture the keynote speaker presented the Vestas’ value management square, that most of all looks like a strategy map or balanced scorecard as Kaplan and Norton would define it.

“The way I see, we add value to the business is to have insight into what systems that the business would need” – Troels Fleckenstein (Week 22, 2011).

Vestas applies a framework that is known as the BSG-model in architecture. BSG stands for Business Service Group that is a sheet of paper detailing how the enterprise works. The documents details how the processes works in the enterprise. The BSGs are linked to the various enterprises processes in Vestas and as such the enterprise architects are working with modeling the architecture a long side the BSGs.

Besides the enterprise architects Vestas applies the title “domain architects” for individuals who have a specific knowledge on how the enterprise applies.

Vestas have made use of IBM, Accenture and other consultancies in order to develop their framework. In other words Vestas Wind Systems have developed a synthesis that hey apply in order to enable the systems.

According to the keynote speaker there aren’t any off-the-shelves process frameworks that Vestas was able to make use of.

“We are not such a box” – Troels Fleckenstein (Week 22, 2011).

Vestas applies Aris as a tool for modeling, but the keynote speaker has a rather controversial view on how the tool works which is represented in the quotation below:

“When speaking of Aris it is quite clear it has been developed by German engineers. It is not made for white people” – Troels Fleckenstein (Week 22, 2011).

Vestas’ IT fundamentals deals with providing fast prototyping, innovation lab, enabling agility, “show me – do it”, safeguard end-to-end transparency of business processes, partnering with the business and providing enterprise architecture to guarantee reliability.

It seems like the approach to Enterprise Architecture that Vestas makes use of, is dealing with communication on how the enterprise can deal with the problems and how the enterprise is able to deal with the problem.

When it comes to the focus on governance and advice Vestas have applied boards for processes, BPS community, Vestas Government and SteerCo where a representative from Group IT (and thereby a representative for the Enterprise Architecture group) is represented. The boards usually handles investments, strategy and innovation, program and projects. One of the many interesting things that Vestas works with in their Enterprise Architecture program is “the line of sight”.

“I’m not a particular big fan of frameworks since they tend to distract us from the communication side of EA and the value adding part of EA” – Troels Fleckenstein (Week 22, 2011).

While educating the enterprise architects Vestas applies an approach where they send their architects to Gartner summits and certification modules. However they haven’t made use of TOGAF or other approaches to Enterprise Architecture.

When Vestas works with IT forecasts they usually take in consultants from Gartner and other consultancies to give the various stakeholders in Group IT ideas on what kind of IT the enterprise should invest in.

Obviously Vestas experiences situations of when and where to break away from their own Enterprise Architecture standards. The way the keynote speaker presented the issue it seemed like that it is based on “intuition” and what the “business” defines as a necessity to cope with. The keynote speaker used an example from the implementation of the windmills and how the various committees dealt with the particular problem.

  • Vestas’ is a rather complex enterprise that have developed its own framework to deal with its architecture.
  • The Enterprise Architecture program is owned by the IT department, or at least it appeared that way while the VP presented the situation.
  • The IT and EA agents are represented in various investment and governance boards in Vestas Wind Systems.

Qualiware Enabling Positive Change

The CEO of Qualiware, Kuno Brodersen, acted as keynote speaker on knowledge management and modeling.

The keynote speaker was of the opinion that the modeling of the change processes is a vital key to success, since the model can help the decision makers and individuals in the enterprise to focus on particular areas of attention.

The keynote speaker was of the opinion that many modern enterprises shares the same view on how the management model. In Denmark most enterprises agrees upon that the Scandinavian management model is the best way to achieve.

A fundamental part of the Scandinavian management model. According to Kuno Brodersen, social capital is what enterprises gains when the social systems solves problems.

There are several factors that impacts the concept of social capital e.g. the individual factors, job factors, group factors, company factors.

In reality these factors have to be included when you measure enterprises and their ability to deal go beyond the expected approach to achieve their individual goals.

“The point of modeling tools is that knowledge from the individual actors in the enterprise are modeling and archived in the model” – Kuno Brodersen (Week 22, 2011).

While implementing the modeling tools it becomes a necessity to involve all of the employees, understand knowledge sharing, we have to focus to create transparent management systems and the system has to facilitate distribution of decision making.

It seemed like that CEO Kuno Brodersen was a bit skeptical about the Gartner Group and their approach to information technology and Enterprise Architecture, though he chose to apply one of their models in order to define the “new way of thinking” in Enterprise IT and Enterprise Architecture.

In the future it becomes a necessity to know how the social networks and the way people interact in social networks in order to facilitate knowledge sharing.

Technology trends will have an even greater impact on how knowledge sharing can be facilitated. In the future modeling software trends like the “Like” feature or comments on the various artifacts. Likewise will the concept of rating most likely be implemented in modern modeling tools.

Features from the social networks will in time be incorporated in to the modeling tools, or this is perspective that Kuno Brodersen presented. The reason for this is that it can be used as a form for “information filtering” and “quality insurance”.

“One of the best qualities of an Enterprise Architecture program is that the various models can be viewed by various stakeholders in the enterprise, and as such this can be used to define the enterprise ontology” – Kuno Brodersen (Week 22, 2011).

The QualiWare EA Framework is an organization of artifacts, but according to Kuno Brodersen, graduate students who are about to start writing on their master thesis could or should think on how the Enterprise Architecture framework represents the “social capital”, social networks, and social knowledge.

Kuno Brodersen presented the QualiWare analytics approach to artifacts and modeling that was build like a balanced scorecard that could be used in order to define how KPIs are aligned with the various processes. As such the data that should be represented in the QualiWare models should be collected from the data warehouses and business intelligence systems, this should add value to the platform for enterprise ontology. His approach to business intelligence and knowledge sharing, Kuno Brodersen, applied a rather positivistic approach and as such this seemed slightly in contrast to his initial approach on the Scandinavian management school; however he did emphasize that the business intelligence approach should be used with caution.

Gamification is “the new black” and it will become part of the modeling tools, or at least this is the views that Kuno Brodersen presented. E.g. Qualiware as a modeling tool has a “treasure hunt” game embedded in the modeling tool in order to train or motivate people in order to make people learn about the new models, processes and activities.

  • New tools are needed to document and deal with knowledge.
  • Enterprise ontology is a part of knowledge management.
  • In engaging the various stakeholders in learning more about the enterprise’s architecture the concept of gamification should be introduced into new products.

The Proof of the Pudding is in the Eating

Olov Östberg was the keynote speaker. As such his presentation dealt with e-government and changing social and technological systems in Sweden.

In his presentation Olov Östberg showed dias that stated that only 18% of IT projects are delivered on time and that are succesfull and he put this in light of the Swedish approach to e-government.. Through time (about 300 years) the Swedish approach to government has resulted into very independent public agencies.

There have been different approaches in order to deal with the data that the Swedish government has collected over time. In the 90s and the early 2000s the focus was onto developing portals.

From his experience there are three levels of e-government that should be dealt with in the future. Government 1.0 is the classical approach, the second level is dealing with more communication and at some point slightly more openness and the third and last level deals with engaging the citizen as a co-creator.

The Swedish approach to e-government includes a rather liberal approach to how the local agencies handles its processes. As such it can become increasingly difficult to implement one approach to Enterprise Architecture. Likewise did the national authorities (the Swedish government) refused to install a national CIO, national roadmap or for that matter a national portal for data and information sharing.

Olov Östberg presented various initiatives on how the Swedish approach to e-government dealt with common problems like insufficient road maintenance, electricity etc.

“We have to realize that the foundation of Swedish society is changing.” – Olov Östberg.

I hereby publish the notes I have taken during the course in Enterprise Architecture that I have attended at the IT University of Copenhagen in the spring of 2010. The compendium is published under creative commons SA, BY, NC which means that it can be used for most purposes; however the purposes have to be non-commercial.

The notes are centered on Bernard’s EA Cube and the statement “EA = Business + Strategy+ Technology” and that has been the key organizer for how the notes are presented in the compendium.

The Foundation for Coherency Management: A Framework for Change.

Posted on

A Framework for Organization to Embrace Coherency Management

When an organization choses to pursuit the implementation of Coherency Management then it the organization have to focus on organizational change. The idea of the organizational change is when the managers, middle managers and the employees will have to work in a different way and humans and organization culture have a tendency to be conservative and react hostile against change.

For this the Coherency Architect should focus on how create the proper form of change within the organization.

A Quick Summary of Coherency Management

Coherency Management deals with how to achieve alignment, agility and assurance through maturing the enterprise’s Enterprise Architecture. According to Doucet et al (2009) then there are three stages for an Enterprise Architecture. The first one is the form that is called the Foundation Architecture which is typically led by the IT department and sponsored through the CIO. The second stage is the so called extended enterprise architecture where both the business side and the IT-organization have adopted and applied Enterprise Architecture to expose the current situation (AS IS architecture) and is used to manage the enterprise’s strategic, business and technology elements.

The third and last stage is called the Embedded Architecture. This particular form of architecture is defined by the most employees in some way or the other work with the Enterprise Architecture. However there are two forms of Enterprise Architects. The first form is the explicit of architect of which there can be defined to dominant forms. The mature and advanced form of Enterprise Architects that are working with an established architecture office that handles the various forms of strategies to create a so called coherent overview. The other form of explicit architect are working with various sub architectures such as the business architecture, technology architecture or the solution architecture.

It is worth to mention that these three stages of architectures are supported by Herzum in his 2003 paper on the topic.

The Framework

When dealing with organizational change then the Coherency Architect needs to work with developing and internal pressure for enabling change. The question can be if the organization is loosely coupled or not. In this particular framework the assumption is that the organization (enterprise) isn’t loosely coupled.

When the organization (enterprise) isn’t a public given monopoly such as the Danish postal services then it will face competition. The competition deals with that the competitors will work for gaining market share this is done through various strategies and those enterprises that sees that they can’t make money in a particular market focuses on differentiating their products or services.

The various moments the competing enterprises makes are in a way a path to more innovation (since it emphasis the development of new products or differentiating the products e.g., make products of a better quality), and this can be defined as a part of the external pressure. It is worth mentionable that not only does the competitors add to the external pressure e.g., the government, press or other external entity. The external pressure can be an enabler for an internal pressure of which is needed to create the urge for change. Change or initiatives for change can be limited through the persistence of organizational culture (as before mentioned organizational culture tends to be rather conservative) and urge is a feeling among the actors within the organization to approve the change initiatives.

It is a preferable situation for the enterprise and the Coherency Architect would be if there can be created a synergy between the external pressure and the internal pressure. This particular synergy would be the burning platform.

When the external pressure e.g., competition, law (regulation) or other element changes in the enterprise’s domino then the Coherency Architect should work with influencing the various groups within the organization that holds some form of power. For this the Coherency Architect needs to produce valid arguments for the need for change and arguments on what to do. For this an elevator pitch can be necessary. According to Bernard (Bernard 2005) then the concept of Enterprise Architecture embraces strategy, business and technology so all of them can be aligned.

The elevator pitch could therefore be something like this “Enterprise Architecture assists in creating a coherent overview of business, strategy and technology”. The elevator pitch has to be supported through an economic and strategical estimation of the benefits that Enterprise Architecture and Coherency Management can add to the enterprise.

When done so then the Coherency Architect should establish an Enterprise Architecture group where he or another person should be appointed the Chief Architect and this person should be granted the resources, responsibilities and power needed to implement an Enterprise Architecture program. Before Coherency Management can be implemented then the organization needs to implement an Enterprise Architecture program and through the principles of Coherency Management evolve the Enterprise Architecture to more than just the “Foundation Architecture”. When establishing the Enterprise Architecture program a suitable Enterprise Architecture framework should be applied e.g., Bernard’s EA 3 Cube framework. The framework should as a documentation form and as a management form ensure that the enterprise’s current projects are investigated and if possible aligned with the strategy, business and technology goals for the Enterprise.

While the Enterprise Architecture program is established then the Coherency Architect should communicate with the sponsors

When the alignment has been established then the Coherency Management framework CoMOF framework should be adapted to the needs of the organization e.g., should issues like repositories be dealt with which leads to the example of the Modular (modular repositories) Coherency Management Framework (needless to say that the framework is based on Doucet et al. basic suggestions for a framework). When the maturing process for the Enterprise Architecture has been matured then it is important for the Coherency Management to verify and moderate the feedback channels that is the foundation of the renewing the Coherency Management and Enterprise Architecture programs and eventually the need for changes have to be implemented along side a new burning platform.

Key Issues

An Enterprise Architecture program should be enterprise – wide and therefore the Coherency Architect will have to deal with resistance to change and for that communication is vital for all the necessary stakeholders. Therefore a communication plan is needed and it has to focus on three particular issues. 1) The stakeholders don’t think like the Coherency Architect. 2) The various stakeholders needs different kinds of information. 3) The need for urgency needs to be enabled through communication and therefore should the Coherency Architect communicate the victories and the victories needs to be sequenced over the period of time one iteration takes and the communication needs to be done in a way that appeal to the feelings of the stakeholders.

Conclusion

When an Enterprise Architecture program and a Coherency Management program is about to be established then it is vital for the success of the program, that the Coherency Architect deals with the issues of pressure to establish a burning platform and then anchor an EA office or for that matter a coherency management office to the power bases in the organization. When done so communication about victories has to be prioritized and sequenced to so the stakeholders continue with their support for both the Enterprise Architecture and Coherency Management program. Since Coherency Management is based on the foundation of Enterprise Architecture then it is a necessity that the EA program is anchored first and for that the proper approach is to apply an EA framework e.g., Bernard’s Enterprise Architecture 3 Cube Framework and use the EA program to align the business and IT projects of the organization to support new or improved business processes (TO BE architecture) that are dictated by the corporate strategy.

When the EA program has been established then the usage of a Coherency Management framework needs to be implemented and the framework needs to be modified to the needs of the particular enterprise e.g., by adding multiple repositories.

When both the EA program and Coherency Management program has been established then it is vital that the Coherency Architect ensures improvement and that can be done by established and routinized channels for verification and feedback.

The need for adaption to the domain of the organization will lead to a continued demand for the establishment of a burning platform.

Artifacts: The Items the Enterprise Architect has to Identify.

Posted on
Reply

Enterprise Architecture Artifact

First of all we need a definition of what an EA artifacts is. Scott A. Bernard defines “an EA artifact as a documentation product, such as a text document, diagram, spreadsheet, briefing slides, or video clip” (Bernard 2004, p. 111).

Please note that the EA artifact documents the EA component. An EA component is in the Enterprise Architecture components are those elements that are owned by Lines of Business. The components can be shared (cross cuts) or the component can be shared a cross various levels (this is with in the EA3 Framework).

Various Forms of Artifacts

There are various forms of artifacts in the EA 3 framework. Combined with the Cube to illustrate what kind of artifacts than can be identified at the five levels of the cube.

The first (and highest level) is the layer titled “Goals and Initiatives” deals with documents and diagrams dealing with mission statement, overall strategy (corporate and IT strategy), purpose of the organization. E.g., SWOT analysis, Porter’s Five Forces analysis, competitive strategy, Concept of Operations.

The second (and second highest level) is the layer titled “Products and Services” deals with the business plans, swim lane diagrams, business cases (for investment in new business and IT projects), use case diagrams and node connectivity diagrams among other stuff.

The third (and third highest level) is the layer titled “Data and Information” deals with identifying the knowledge management plan, the information exchange matrix, objects state – transition diagram, logical data model, data dictionary / object library.

The fourth (and fourth highest level) is the layer titled “Systems and Applications”that deals with identifying systems interface diagram, systems communication diagram, systems interface matrix, system data flow diagram, system or operations matrix, systems data exchange matrix, systems evolution diagram and web application diagram.

The fifth (and fifth highest level) is the layer titled “Network and Infrastructure” deals with identifying artifacts like network connectivity diagram, network inventory, capital equipment inventory, building blueprints, network center diagram, cable plant diagram and the rack elevation diagram.

Acquiring the Artifacts

When the Enterprise Architect or for that matter the Coherency Architect have to acquire information on the various layers in the EA3 Cube.

The Enterprise Architect has to go to the CIO or other members of the executive group who the Enterprise Architect assumes have access to the corporate strategy and the IT strategy. However many organizations there aren’t isn’t an IT strategy or for that matter an explicit up to date the corporate strategy. Most of that information that all in all can be combined into a functional strategy.

In such cases the Enterprise Architect has to go an interview the stakeholders. However the Enterprise Architect should expect that he or she hasn’t unlimited resources to investigate and uncover the strategies (level 1). He or she should therefore try to focus on the stakeholders that can give them the greatest amount of value through the uncovering process.

The persons or stakeholders should be set into a matrix where the axis should be aligned around importance and impact on the uncovering process.

Importance - Contribution Matrix.

Importance - Contribution Matrix.

When the various stakeholders have been identified then those actors and stakeholders who are in the upper right quadrant should be interviewed. If it is possible then those persons who are in the lower right quadrant should be engaged as well however only as second or third priority.

When interviewing the executive group the Enterprise Architect should focus on applying techniques that enables the interview victims on expressing what they mean by illustrating the strategy e.g., rich pictures, flow charts, concept of operations diagrams etc.

The interview technique could be applied on the other levels in the EA 3 Cube. Likewise can the various managers and employees be categorized in the matrix and likewise should the Enterprise Architect focus on maximizing the values of his work through interviewing those persons who have contributes the most and who are most important to the data collection.

Conclusion

The Chief Enterprise Architecture should work with identify the proper stakeholders and make use of interview techniques to collect the necessary artifacts they need to create the “AS IS” view of the Enterprise Architecture. All organizations faces the conflict of resource shortage which means that the executives needs to prioritize their actions to create maximum value and that includes the way the Chief Enterprise Architect and the Enterprise Architects should handle.

Bushido of the Coherency Architect: The Ways of the Coherency Architect to Efficiently Apply Suitable Solutions!

Posted on

The Path to Improvement

The focus is to combine lean, Toyota Production System, Enterprise Architect and Coherency Management into a guide line like the Bushido: The ways of the warrior.

The main principle of Coherency Management is to implement a holistic management approach that enables the management to achieve alignment, assurance and agility.

Enterprise Architecture is the foundation of achieving Coherency Management and it is possible to combine that with efficiency to achieve an enterprise that have a lesser amount of slack and adds more value to its share holders and customers.

First of all an Enterprise Architecture program has to be established.

Second of all an economic analysis of the activities that the organization performs to get income.

Third of all communication of change needs to be performed. That means that the Chief Enterprise Architecture needs to communicate to various stakeholders. The various forms of stakeholders needs to be dealt with in different ways. The various stakeholders needs different kind of information.

Third of all the Enterprise Architect has to work with various applying a framework e.g., the EA3 Framework, TOGAF, OIO or other framework.

Forth of all the Chief Architect needs to demonstrate the value of the Enterprise Architecture. The Enterprise Architect should apply the evaluation models that give the information that the stakeholders needs to make their mind (approve or disapprove) the Enterprise Architecture program. It is necessary to apply the evaluation model for the business processes and IT processes before the EA program has been established. This is needed to compare the before and after approach.

Fifth of all the Enterprise Architect has to make use of his or her talent to deal with the persons who have to change their way of working after the Enterprise Architecture program has been established. According to Doucet et al. (Doucet et al 2009) then the organization then there are three forms of applied Enterprise Architecture. The first form is known as Foundation Architecture. The Foundation Architecture is when the organization has applied Enterprise Architecture in the IT department. The IT department has been the driver of the Enterprise Architecture and made use of it to uncover the the operational model of the Enterprise Architecture. When the organization mature the Enterprise Architecture then it should over time come to the Extended Enterprise Architecture where both the business side of the enterprise and the IT side. The IT side and the business side works uncovering the business and its processes. There are several forms of architects who have various functions and responsibilities. There will be a centralized office for Enterprise Architecture and there will be a commitment from the Executive Group1 to enhance and use Enterprise Architecture to govern the enterprise. There are business architects, process architects, technology architects information architects and the Enterprise Architects. The Enterprise Architects will be dealing with handling the overall aspects of Enterprise Architecture. The Enterprise Architects will be dealing with keeping the other architects in line with the Enterprise Architecture program.

After the Extended Enterprise Architecture level then the organization will be moving toward the Embedded Enterprise Architecture. The form of architecture is so far a kind of utopia where every employee in some way acts as an architect which leads to that there are explicit and implicit architects. Theres is a focus on a central EA department that consist of the best Enterprise Architects who works with the overall Enterprise Architecture framework and enabling the other architects with their work through empowering the framework and governance of the Enterprise Architecture.

Sixth of all the Chief Architect has to implement a Coherency Management framework so far there is only one kind of a kind. That means the CoMOF framework has to be adapted. As it is with all other frameworks then the CoMOF framework is a generic framework and it has to be modified for the particular organization. While applying the modified CoMOF framework in the organization then Coherency Architect (or Chief Architect) has to make use of the efficiency theories such as LEAN, Six Sigma or Toyota Production System. This is a necessity to improve the organization’s enterprise.

Seventh of all the Coherency Architect has to ensure that executive group continues supporting the Enterprise Architecture program and Coherency Management program. This have to be done through emphasizing the support for Enterprise Architecture by using external pressure to enable the internal pressure(groups with power) to invest resources into renewing the program. If the Enterprise Architecture program isn’t renewed then the value of the Enterprise Architecture program will lose value. The same is the case for the Coherency Management program.

Eight of all the Chief Enterprise Architect should be working for improving the channels of how the Enterprise Architecture is transforming.

The Code

The Coherency Architect should be therefore be working with being efficient, effective and use his or her experience to develop develop efficient enterprises through Enterprise Architecture.

  1. Focus has to be on efficiency and effectiveness. The ideal is that the Coherency Architect should be thinking in systems where to much slack is minimized; however enough slack to harvest the benefits of innovation.

  2. The vision of Enterprise Architecture has to be communicated to the stakeholders . The people skills and abilities to communicate fluently with people are virtues.

  3. Improving the Enterprises and their Enterprise Architectures then the Coherency Architect have to focus on influencing the organization cultures to institutionalize improvement through Enterprise Architecture.

The Steps of the EA approach

There are defined 20 steps to establish the EA program according to the EA 3 Cube framework (Bernard 2005). The 20 steps have different importance in the four different phases which needs to be taken into consideration.

The first and thereby primary step is the establishment of the EA program. If the EA program isn’t established the organization will experience difficulties with improving its Enterprise Architecture.

The second phase deals with how the organization should define an methodology and the tools that are compatible with the EA approach (framework). If that is not in order then the EA program will not aggregate a proper view “AS IS” perspective.

The third phase deals with how the execution of the EA documentation program.

The fourth phase deals with how the EA program should be linked to the management and other kinds of management processes so the organization can generate the full advantage of the investment in the program.

Phase 1: Establishment of the EA Program

  1. Establishment of the EA Program and identifying the EA Chief Architect.

  2. Establish of the EA Methodology.

  3. Establish EA Governance and links to other management processes.

  4. Develop an EA communication plan to ensure EA stakeholder buy in.

The EA Program needs a person in charge to apply the right framework and the right tools and the person needs to be hold responsible and accountable. This means that the top management and management of the organization needs to buy in (#4). If they don’t buy in then the EA program will easily be detoured.

The EA program needs to be linked to other management processes so they can be coordinated and when they are coordinated they can become a greater asset for the organization. When the coordination has been established and the coordination has been applied then it might turn into a competitive advantage.

Phase 2: EA Framework and Tool Selection

  1. Select an EA documentation framework.

  2. Identify the EA lines of business (LOB) and cross cuts and the order of the documentation.

  3. Identify the EA components to be documented framework – wide.

  4. Select documentation methods appropriate to the EA framework.

  5. Select the software applications or tools to support the automated Enterprise Architecture documentation.

  6. Select and establish an online EA repository for documentation and analysis.

The documentation framework is frame for how the various elements have to be put into to create a systemic analysis. The analysis have to be focusing on identifying symptoms and finding the cure for the right problems within the organization.

The Enterprise Architecture should be documented so an “AS IS” is produced and used as a blueprint so management and the EA program chief architect can articulate a transition plan that can enable the organization to achieve its goals and thereby create the “TO BE” situation for the enterprise architecture.

Phase 3: Documentation of the Enterprise Architecture

  1. Evaluate existing business and technology documentation for the use in the Enterprise Architecture.

  2. Document the current views (AS IS) of the existing components in all frameworks areas (levels). Organize and store the artifacts in an online repository.

  3. Develop future business / technology operating scenarios.

  4. Identify future planning assumptions for each future scenario.

  5. Use the scenarios and other program / staff input to drive the documentation of future EA components in all EA framework areas. Store artifacts in the online repository.

  6. Develop an EA management plan to sequence the planned changes in the Enterprise Architecture.

The business and technology documentation is needed to create the “AS IS” since the EA consist of Business, strategy and technology and acts as a kind of governance tool for the organization.

The scenarios needs to deal with a positive scenario where everything stays the same and a scenario where things change and a scenario where everything goes down the drain (worst case scenario).

Involve the the staff to assist in making the documentation since many of them probably act as SMEs (Subject Matters Experts).

The EA management program needs to be the blueprint for changes that needs to be implemented in the enterprise architecture. This means that the program will have to be broken down to projects that can change the various components (and other elements of the enterprise architecture).

Phase 4: Use and Maintain the Enterprise Architecture

  1. Use EA – documentation to support planning making.

  2. Regularly updates current and future views of the EA components, and link information in the EA repository to create high – level and detailed perspectives of Enterprise Activities and resources in the current and in the future operating environment.

  3. Maintain EA repository and related EA modeling and analysis capabilities.

  4. Release annual updates to the EA management plan.

When working with the EA framework then it should be used to assist in the planning making (the transition plan) and not to mention that the methodology needs to be in place for the transition plan.

The EA repository needs to be maintained so every stakeholder in the organization can relate to the objects and terminology in the same way.

The EA management plan needs to be updated so it is matches the changes in the domain.

Information Systems and Enterprise Architecture: An insight to Zachman’s Initial Ideas on his Framework.

Implementation of Information Systems

The development of information systems have become more complex. The development of the systems and the cost of development has to lead to that the systems can minimize the barriers (constraints of the organization system).

The complexity of the systems leads to issues that the system only adds value to the organization when it is implemented. The barriers that have been diminished by the information systems have lead to that many organizations have become more flat in their structure.

The flatness of the structure leads to decentralization. The decentralized organization will end in anarchy if the system is not build upon an architecture. Zachman deduces that the information systems architecture is related to strategy both the corporate strategy and the IT strategy.

Since it becomes of strategic importance then the enterprise has to invest more attention to the concept of the Information Systems Architecture. The meaning of an Information Systems architecture is losing its meaning without the creation of a framework (this was later known as the Enterprise Architecture framework or Zachman’s Framework).

The framework and the paper is not supposed to present a new strategy planning framework though as before mentioned the foundation for IS architecture is closely related to the concepts like IT strategy and business strategy. The Focus on Architecture The framework was in its origin based on ideas that origin from the architecture paradigm. This means that Zachman is of the idea that enterprises (organizations and companies / corporations) can learn from the thousands of years of experience. The Bubble Charts and the Process Along The first step for an architect is to draw a bubble chart. The bubble chart shows the relationships among the various components.

Thereto the bubble char indicates the shapes and the size of the building. The purpose of the bubble chart is to deal with the communication between the architect (later the Enterprise Architect) and the customers. Then the bubble chart is refined to something a bit more “serious”. This is called the “the architect’s plan” of which the contractors and the sub-contracters will draw their plans. It is notable that the plan might change several times since the estimated costs will lead to changes in the design since the cost is a constraint. This means that the chart has to include more information in a more precise sketchup. Which leads us further into the analogy. The contractor then redraws the architects plan so it fits with the perspective of the persons who are building the systems. Zachman summarizes the various design plan purposes in a table similar to this. It is worth mentioning that the “Nature or Purpose”:

The Public Sector has to take Charge of its IT Architecture

The public sector has had a sector wide view on IT investments (that includes investments in information systems and architecture) that they should focus on purchasing the cheapest and most relevant solution.

The cheapest solution has often led to that the solution has been developed with in a narrow scope. This has had an impact on the IT architecture since it has been optimized for the local department or unit. The result of this is in general not desirable since the government in 2003 articulated goals for that the architecture should be scalable and reusable.

The suppliers to the IT architecture are still in charge of developing components and implement the business logic. The public sector then have to demand a common set of standards to enhance interoperability.

The reason for the public sector should promote these demands are that the level of competition will become more intense which will be an advantage for the public sector.

The public sector has to realize that if it wants to be ahead of the suppliers and thereby gaining a competitive advantage then it should focus on developing its employees in the skills of Enterprise Architecture or IT Architecture Management.

According to John Goetze the reason for why the public sector (the ministry of Research and Science) chose to name the concept IT Architecture due to the secretary of Research and Science preferred the name “IT architecture” compared to the title “Enterprise Architecture”.

A common IT Architecture Framework

The framework focuses on coordination, a common set of methods, a common choice of methods, systems and principles, and common tools.

The common coordination deals with that the public sector should establish a committee that create the common IT architecture that public sector should mature and develop. The common frame of method is a common standard of processes, concepts and processes. The common choice of systems and principles deals with the public sector should deal with standards and infrastructure that should led to a reference profile and a Service Orientated Architecture.

The common set of tools deals with establishing common databases, libraries, contracts, description of processes, definition of data, software components including descriptions of infrastructure solutions.

Consequences

To promote the usage of IT and the be able to scale the systems across several departments, ministries, counties, communes and other public administrative sectors and institutions can make use of the stored data.

The public sector will experience that the costs for developing the IT architecture and the costs of the processes will also diminish over time.

However when the organizations within the public sector in one way or the other invests in a new information system then the specific organization has to apply specific controls and methods to ensure that the systems are designed and optimized for the specific processes (of course build the reference public reference profile).

The new repository and framework will give the public sector the benefits of organizational change and the understand of systems changes as well since they are build around the same systems and principles of management and Service Orientated Architecture. It is notable that the implementation of the IT architecture will be a hugh investment and the investment can result in big benefits and opportunities as well.

The Background for the OIO-framework

The reason and background for the development of the public IT architecture (and the OIO-framework) is to establish a foundation for Enterprise Architecture to ensure maturity in the common enterprise architecture to enhance and develop public services to citizens and customers.

The government has established a vision for what is known as digital governance & management. The vision is based on four goals (principles) that needs to be taken into consideration:

  1. The digital governance & management has to empower the citizens and corporations to the network society.

  2. The public sector has to work and communicate digitally.

  3. The public sector has to provide coherent services and products to the citizens and the corporations.

  4. The tasks in the public sector has to executed where the tasks can generate the largest benefits.

The above mentioned goals have to be translated into processes and these will be implementing over several years and with different development logic.

  1. Goal two to four deals with that the IT architecture should better public support through higher quality in the IT foundation.

  2. Support the development of innovative cross governance processes through greater coherence in the informations.

  3. Achieve a more effective governance through larger efficiency in IT usage.

  4. Gain access to rapid support of new or changed governance processes and organization changes through tested infrastructure solutions.

  5. Give access to public information through open to citizens, corporations and public institutions and authorities.

  6. Give sufficient protection of public information through secure solutions to manage and communicate data.

  7. To create more successful IT solutions through larger predictability of the results of IT investments.

  8. Give the public sector access to stabile IT systems with sufficient capacity.

Experiences that can be Crystalized from the OIO-framework

There are several other countries that have made an effort to implement IT architecture (Enterprise Architecture) and these countries have gained some experiences.

These experiences are as follows:

  1. Commitment has to be on government level.

  2. A cross government institutions and departments collaboration is needed.

  3. Standardization of data structure and functional data interfaces has to be implemented.

  4. Choice of technical standards are needed.

  5. A common infrastructural platform has to be implemented.

  6. Anchoring the knowledge and change through certifications and common shares of practice have to be implemented.

Guiding principles

The OIO-framework emphasizes 10 principles that the Coherency Architect has to take into consideration when the government of one reason or the other implements a new IT architecture:

  1. The Service Orientated Architecture is a paradigm of which the government has to invest its resources so a coherent digital governance can be applied.

  2. The prospect is that the government will take an active role in the service orientated architecture.

  3. The national common IT architecture has to be the lowest common standard that in the same time enables the ability to add to it (a kind of dogma architecture).

  4. The IT architecture should reflect the vision of the business side and there should be a consensus regarding the choices the business side has committed itself to.

  5. The national IT architecture should be applied in those cases where there is a business needs and business analysis should support the usage of the usage of the IT architecture.

  6. Legacy systems shouldn’t be scraped or for that matter be converted to run on the same platform. In the other hand none of the legacy systems should be spared in advance of the implementation.

  7. The implementation should focus pragmatic assumptions and the implementation should be done in iterations.

  8. The IT Architecture should be based on the lowest possible political foundation to ensure that those persons who know about the situation locally can take the proper responsibility and accountability for the situation and implementation.

  9. Denmark is not the only country on this planet and therefore should the work with the architecture be coordinated with international players.

  10. The work with the IT architecture and the standards should be published on a public website www.oio.dk.

The IT Architecture Process

The white book is based on two cycle processes that enriches each other while they are executing. The two processes are iterative which means that these have to be executed continuously.

Since the public sector is rather decentralized and therefore is the principles and concepts discussed in the white book based on the idea that these can be dragged down onto the various self-governing institutions and their contexts.

Strategy Process.

Strategy Development Process.

It is worth to mention that the upper circle is the strategic process and the lower circle is the implementation process.

  1. Vision and goals describes the strategic business goals and that will be with a special focus on those that are related to Information Technology. It is a necessity to keep a dialog with the top management of the enterprise and the political side of the business is a necessity as well.

  2. The Business Architecture describes those processes the IT system has to support both when it comes to functionality and procurement. This state is a result of an analysis and an optimization of existing work related processes.

  3. The Information Architecture describes the business strategy and its demands to the organization of information. This contains both the high level description and low level technical description.

  4. The Technical Architecture is based a common shared systemic description of the demands which can be categorized with the high level part of the systems and modules and the low level description of each of the modules.

  5. The Conceptual Architecture Principles is a rule set that handles the initiation of the IT solutions so these are within the demands presented in the “Conceptual Architecture Principles and former mentioned architectures”.

Besides the strategical architecture process the practical implementation process will be executed.

  1. Document the existing situation (AS – IS).

  2. The Gap analysis deals with identifying the identifying what legacy systems that fit into the conceptual architecture principles.

  3. Prioritization and planning. This phase deals with the planning the technical change that is needed to bring the “AS IS” to the desired state “TO BE”.

  4. Implementation projects deals with implementing the changes through a series of projects.

The Three Layer Model

The three layer model can be utilized and linked directly to the architecture model.

  1. The user interface layer (3-layer) that is directly linked to API & Services and Presentation.

  2. Business Logic Layer (3-layer) that is directly linked to application server, integration server and database sever.

  3. Storage Layer (3-layer) that is linked directly to server hardware and operating system, data layer, and network.

When the public sector starts the redefinition of its “Enterprise Architecture” (IT Architecture) then it should focus on to break down the known barriers and not just enabling old government procedures or processes. This means that the old processes should be supported with new technology since they often just led to the same result as the old processes and these rarely enables the true potential of the technology.

Principles

The foundation of work with IT Architecture (Enterprise Architecture) is based on the principles developed by the chief architect and the EA team.

On the lowest level of principles we find the principles that are focused on a specific system where we in the highest level is based on the idea that the entire enterprise should align their decision making with.

The principles should be build upon:

  1. Interoperability is a necessity to enable the usage of and recycle the data. However interoperability can also be viewed as a way to create coherence in new ways.

  2. Security is a paradigm and an imperative. If the system is not based on the

  3. Openness is based on the idea that the interfaces have to be open so the can ensure communication and interoperability among the systems components.

  4. Flexibility is based on the idea that the system has to be build so it would be easy to modify to the system (enterprise architecture will be suited to its surroundings).

  5. Scalability deals with how the system will be working when there is a greater demand for its features and usage.
