A Model for Literature on Enterprise Architecture

I have been working with several different perspectives on governance, strategy, it architecture and enterprise architecture. I have read several books on the three topics and as such I have been able to build a model for categorizing the literature.

The Model

The model is segmented into three different levels and three different categories. The first (vertical) category deals with information and how information is used. The second (vertical) category deals with strategy (you shouldn’t articulate a strategy that isn’t based on information). The third category (vertical) is about innovation since strategy is often about doing new things and do them well in order to move the enterprise.

The categories that are horizontal deals with different perspectives and as such as economy, organization and technology. There are some “blank” spaces in between the three horizontal categories and as such these should be seen as in the spectra of the three perspectives.

The various authors that I have organized in the model have been mentioned under the Harvard source notation standard e.g. Beer (1994).

The model is essentially constructed upon the same principles as Leavitt’s model for organizational and technological alignment which means that I can only recommend the reader to read books with-in all of the perspectives in order to gain a holistic understanding of what Enterprise Architecture is all about. The model is of course a simplification of the reality.

Feel free to contact me if you feel that other books should be added to the model. You can contact me by comment this blog post or using the contact form.

The Enterprise Architect: The Abilities of the Enterprise Architect, and what Should be Expected of Him.

The Enterprise Architect

There is no real definition of what an enterprise architect is or what he or she does. There is no exact definition of what the enterprise architect does and where he can be found in the enterprise. There are many different disciplines within the sphere for the enterprise that has something to do with Enterprise Architecture.

According to Doucet et al (2009) there are both explicits and implicit roles dealing with enterprise architecture, especially if the architecture is mature. The roles all have something to do with being enterprise architects, and there are different ways how they interact with the architecture.

The Chief Architect is according to Bernard (2005) the person who is in charge of establishing an Enterprise Architecture group in the enterprise, and likewise is it the Chief Architect who choses or creates a synthesis for a framework that can be made use of in the particular enterprise. It is Chief Architect who selects who are to take part of the particular enterprise architecture group and what each individual is supposed to do.

The definition that Bernard proposes is that the enterprise architect is a kind of liaison among other forms of architects like solution architects, technology architects, business architects. The enterprise architect the person who works as liaison but also the person who translate, codify and organize the various artifacts.

At the conference on Enterprise Architecture in Copenhagen 2010 the representative for The Open Group said “that The Open Group Architecture Framework has to be adapted to the individual enterprise otherwise wouldn’t give the enterprise any value to make use of it” this particular statement from the largest provider of frameworks illustrates the importance of the Chief Architect and the synthesis process. It does also stress the importance of the highly adaptable enterprise architect who can see possibilities and act upon them.

Op’t Land et al (2009) presented in the book “Enterprise Architecture: Creating Value by Informed Governance” different roles that characterize the enterprise architect. They define the roles as follows:

  1. The Change Agent. The change agent has to encourage both the management and the employees to change their views on what Enterprise Architecture is, and adapt the policies and programs that the Enterprise Architecture can generate for them.

  2. The Leader as having a vision for the Enterprise Architecture program. This includes a visionary focus on the various strategies and how they influence the Enterprise Architecture program.

  3. The Manager has to make sure that the Enterprise Architecture Program is dealt with and updated so it entails the proper way to do practices, projects and principles are kept alive and these are meaningful for “the business” of the enterprise.

  4. The Communicator is one of the roles that the chief architect and the team of enterprise architects have to master to achieve that the various stakeholders collaborate.

  5. The Modeler is a role that is necessary to master for any given enterprise architect, otherwise wouldn’t he or she not be able to create the META-models needed to show how the enterprise works and should be working.

Furthermore did Op’t Land et al (2009. p 119) argue that the Enterprise Architect has five different ways of thinking within the perspective of working and changing the enterprise. These ways of thinking are dealt with below.

  1. Yellowprint – thinking that deals with brings interests together, the approach includes stimulating stakeholders, formulating opinions, creating a “win – win” situation and forming coalitions.

  2. Blueprint – thinking that deals with formulation of unambiguous objectives, development of an action plan, that includes monitoring and adjusting the change process accordingly.

  3. Redprint – thinking deals with ensuring people are aware of new perspectives, ensuring that they (people) are aware of their personal shortcomings. Last but not least does it deal with motivation of the people to see, learn and do things. The focus is the learning process.

  4. Whiteprint – thinking deals with articulation of plans that includes people’s processes, interests and energies. The focus deals with the removal of blockades and barriers.

All of the above mentioned ways of thinking are necessary for the enterprise architects to be able to operate with the Enterprise Architecture approach. It depends on the situation and the the maturity of the enterprise’s architecture.

In conclusion it is important that the enterprise architect can see possibilities and he or she is able to act upon his justified instinct and deal with various people who work and thinks in silos or sees the world very differently from the Enterprise Architects. The Enterprise Architects would have to be able to sell the idea of Enterprise Architecture to people who resent holistic approaches and systems thinking and in the same way be able to be diplomatic.

All of the above mentioned characteristics are to be operationalized in the enterprises regardless of how mature their Enterprise Architecture programs are. Furthermore does the views that Hoogervorst et al (2009) presents and the views that I present in this blog post indicate that the enterprises would have to test the enterprise architects in order to investigate what kind of architects they need and define what roles they would have.

The Chief Architect and the Roles in the Enterprise

Doucet et al (2009) argues that in order to mature the enterprise’s architecture it is a necessity to change a few roles within the management group and for that matter within the IT group. Doucet et al. argues for the changes in the IT – organization is because the concept of Enterprise Architecture originates from the IT department and the world of Information Systems it is a necessity to force the management of the IT department (and this usually includes the management of the Enterprise Architecture group) to think in new ways.

Doucet et al argues that in the perfect world the ownership of the Enterprise Architecture program has to change from the IT department (the CIO) to a leader within the organization who works with the operations or other executive.

In my opinion the change of focus is needed as long it doesn’t mean that IT and the enablement of new and old business processes aren’t neglected. Likewise does Potts (corporate strategist, speaker and author) advocate for a new and slightly different approach to IT management and IT investment. His approach that entails that the CIO role should be abolished and replaced with the role of chief internal investments officer (CIIO).

The CIO or his successor CIIO should deal with corporate transformation through investment planning and corporate program management that would have to entail all strategically important projects. Strategy is according to Potts the implicit and it is defined by the embodiment of actions taken by the executive group. This is in its way a perfect situation for the chief architects and for that matter the enterprise architects since they would be able to identify how the enterprise has invested its resources and how they in the future would be able to invest.

The Elite Architecture

According to Doucet et al (2009) the focus of working with the Enterprise Architecture program is to go beyond the IT – centric approach that usually is applied in the IT department. In this approach it becomes a necessity to work with the maturation of the Enterprise Architecture program and by that establishing a group of elite architects who in term work withs the focus of developing and adapting the Enterprise Architecture approach to solve the problems that the enterprise experience. The focus of the elite architecture is to aid those enterprise architects that are involved in the various business units. In other words the focus is to facilitate a community of practice.

The establishment and later on the facilitation of communities of practice seems to be the greatest difficulty for the enterprise.

In my opinion it isn’t possible to establish communities of practice, they are simply a social phenomena that happens if the right people are present at the right time. However it is a possibility to facilitate the communities of practice after the enterprise has identified what they are and who participate; however this is only possible to a certain degree.

If the management or other element within the enterprise begin to interfere with the community of practice it will eventually become irrelevant and dissolve itself.

Communities of practice are too specialized in their ability to deal with their tasks, and impact of the behavior of the people who participate in them are to random to any kind of generic rule for dealing with facilitation of communities of practice can be established.

Focus has to be on the enterprise allows people from different parts of the enterprise to meet in areas suited for meetings and informal talks.

The community of practice would enable the enterprise with achieving an elite architecture team and as a result an elite architecture program.

The architects would have to interact with one another in different ways and tasks where they can take advantage on the expertise that they posses and the understanding of these expertise and the registration of knowledge abilities they posses.

In order to achieve elite architecture the enterprise would have to establish an incentives program that ensures that the enterprise architects who evolve with the Enterprise Architecture program can handle tasks that are suitable for their personal development and as such could this enable the enterprises to retain knowledge on how to innovate, develop, deploy and mature its enterprise architecture. It is needless to say that the hypothesis of this blog post is that the more mature the enterprise’s architecture is, the better the enterprise would be able to assure alignment, assurance and agility and through that would the enterprise be able to crystallize competitive potential into competitive advantages.
