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.

  1. This is copied directly from Scott Bernard’s own book, right? As far as I can see, it is just a copy or paraphrasing of what he already wrote.

    1. Hi Bruce H. !

      It isn’t ‘directly’ copied from Bernard’s work “An Introduction to Enterprise Architecture”. It is a summary based on my own notes taken during a class in Enterprise Architecture. To make it clear then I have added “Sources” of that refer to the book.

      Best wishes,
      Peter
