What is the purpose of the “Define the EA Meta-model” process?


Define the EA metamodel.

This process defines the Meta-model that will be used for gathering and analysing information that is to be stored in the EA Modelling Tool.

Since some EA Modelling Tools have pre-existing and somewhat static Meta-models this process may not be required. However, even if the approach is to use whatever Meta-model that comes with the Tool that will be selected, it is still a good idea to go through this process to identify the initial entities, relationships and views that are initially important to the Enterprise as beginning with a massive and detailed Meta-model can dilute the focus.

Another dimension to be aware of is that whatever Meta-model is chosen, the Meta-model will expand as times goes on and therefore consideration should be given not only to the initial Meta-model but also how that Meta-model will grow over time.


¨      Find out what Meta-models exist and how they map to the PEAF Ontology.


¨      Using the Artefacts section of PEAF, decide what Meta-models are required.

Plan Transition

¨      Create a detailed plan of the things that need to be done to rollout the changes made and make them real.
