The Architecture Crystal Ball: Predictions for 2012

Posted on by

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.

The Foundation for Coherency Management: A Framework for Change.

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.

The Enterprise Architecture Framework

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.

The OIO-Framework: The EA Framework Designed for the Danish Public Sector.

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.
