Enterprise Transformation

A Pragmatic Approach Using POET

Here we see a way of understanding of how the utilisation of XOET (which is an Enterprises Operating model for Enterprise Transformation, based on POET) and XEAF (which is an Enterprises Enterprise Architecture Framework, based on PEAF) plays out when applied to actually doing Transformation.

While the approach described here is changing the Transformation domain (or more specifically the EA part of the Transformation domain) the process described actually is the same for changing any domain, i.e. create a Physical intermediate state model based on physical current model, and logical and conceptual Target models. Then use that Physical intermediate model to determine a plan to change the MACE that exists. This fundamental approach is detailed in more detail in the Methods section.

So let’s walk through what’s happening with respect to maturing the EA domain and the part that POET and PEAF play in that.



The centre of the diagram represents the Transformation capability of an Enterprise, which utilises Transformational information on the left, and Structural information on the right. It comprises the 6 phases of Transformation (Strategising, Roadmapping, Initiating, Elaborating, Constructing and Transitioning) and takes information though 5 levels of abstraction (Contextual, Conceptual, Logical, Physical, Operational) culminating in physical changes at the bottom.



Looking at the Enterprises Transformation capability in the middle, we can model these phases of Transformation at different levels of abstraction (Contextual, Conceptual, Logical, Physical, Operational), and for each level of abstraction, we can model the Methods, Artefacts, Culture and Environment for that phase.



We can now show:

a) How XOET provides the models at the Contextual and  Conceptual levels for all phases of the transformation domain

b) How XEAF provides the logical model for the Strategising and Roadmapping phases (EA) and,

c) How XEEF provides the logical model for the project phases of Initiating, Elaborating, Constructing and Transitioning.

We can also see that The Physical model, Operational model and Physical World levels are Enterprise specific, because this level of detail is generally different for each Enterprise, but is created by the Enterprise, under the guidance of the models above them provided by XOET, XEAF and XEEF.



Finally, we show that the Methods (for each phase) drive the “How we will Transform”, and the Artefacts (for each phase) drives the How to model the “Domain to Transform”. The Culture and Environment parts, provide the (Human and Technical environment used for each phase.


Questions to ponder...

Does this approach look familiar?

What approach does your Enterprise take when maturing parts of it?
