A Pragmatic Approach Using PEAF


◄◄◄ Previous Page

PEAF is a framework and therefore is governed by EMMA (The Framework Ontology) for its use and adoption. The three phases, as defined by EMMA, map to the six fundamental phases of Transformation. For each of the phases, we indicate (in green) the resources that phase will require to execute and (in red) the resources that are being sought to execute the next phase.

¨      Evaluate - Measured in days.

¨      Strategising - EA - Why Should I Care?

This sets out the high level reasons why any other work related to EA should take place. It should take less than 30 minutes to explain to a member of the C-Suite or senior Executive and sets the domain of interest.

¨      Roadmapping - Select EA Framework.

This allows for the review and ultimate selection of an EA framework and to perform a high level evaluation of the Enterprises EA Maturity to determine what work is required to utilise it.

In addition, at this point, it may also be decided that other sub-parts may require improvement. If that is the case then those initiatives would begin their own journey using EMMA with Strategising and “Why Should I Care?” and would become sub initiatives.

¨      Analyse - Measured in weeks.

¨      Initiating - Understand EA Framework

Here we do whatever is necessary to understand how to apply PEAF. This may entail reading books, attending workshops or training, using a consultancy or any combination thereof depending on the Enterprise and the individuals involved.

¨      Elaborating - Plan Rollout of EA Framework.

Here we use PEAF to consider our maturity in detail. What level we are, what level we wish to attain, what the benefits are, and what actions need to be taken in order to effect that increase in maturity.

¨      Modify - Measured in months.

¨      Constructing - Develop Changes.

Here we use PEAF to produce the things required to effect the increase in maturity.

¨      Transitioning - Rollout Changes.

Here those things are rolled out into live operation.

The ultimate goal is to increase the effectiveness and efficiency of the domain in question.


Questions to ponder...

Does your Enterprise care about EA?

Does your Enterprise periodically evaluate its EA maturity?

Who is responsible for that?

At what maturity level is your Enterprise?

Is that an appropriate level for it?

If not, what do you need to do to increase it?
