Crossing the Chasm: Progressive​ Enterprise Architecture Model (PEAM)

[Updated October 5, 2016]

Inspired by Gerben Wierda’s thoughtful discussion about how the full framework is depicted in the new ArchiMate* 3.0 specification (An AchiMate 3 Map (Layers? What Layers! — 1)), I’m going to suggest there’s another level of improvement that can be made to the specification’s “peanut butter and jelly sandwich” diagram. [Please excuse the visual metaphor but that’s what it looks like – with PB&J leaking out on all sides.]


Figure 1. ArchiMate 3 Layers and Aspects

In his posting, Gerben suggests a succession of improvements (depicted below).

But they still left my question unanswered: Why were Strategy, Motivation, Implementation & Migration left as disconnected layers on opposite sides of the enterprise architecture map? [I don’t accept Motivation being classed as an Aspect but that’s a topic for another article.]

What happened to the architectural principles of simplicity and elegance?

Aren’t the following series of enterprise architecture maps more informative and more understandable?  …more pragmatically useful?  I refer to the version below as the Progressive Enterprise Architecture Map.

p.s. If the arrows make the enterprise architecture map too prescriptive from a pure ArchiMate specification perspective, what do you think of this version?

p.p.s. In October 2016, in the article Crossing the Enterprise Architecture Chasm, I extended PEAMs to include:

  • Continuous Transformations
  • Strategy Chasm
  • Enterprise Architecture Chasm

What’s the difference between improving the design and operation of an aircraft engine vs. an enterprise?

Answer: Nothing

Continuous Transformation 2

Continuous Transformation is a key principle of the Progressive Enterprise Architecture Model (PEAM); part of the practice of Total Enterprise Architecture Management (TEAM).

Please post your feedback in the comments …good or otherwise.  Please let me know what you think and, more importantly, how are these helping you and what you would like to see next?
