As the process of matrix #2 (enterprise engineering) results in all deliverables of matrix #3 (the enterprise) it is relevant to ask: what is the process that brings about the enterprise engineering process and is it of interest to the enterprise integration community?
It is proposed that the subject matter of matrix #1 is the life-cycle of strategic enterprise management (SEM). As SEM operates it brings about (among other things) enterprise engineering projects.
Although not all subject matters in that matrix are directly relevant to enterprise engineering, some parts are. Namely, the methods for the identification of the necessity and the starting of enterprise engineering efforts belong to the operation of Strategic Enterprise Management and these methods should also be part of the generic enterprise integration methodology. Similarly, the selection of suitable methodology (and the methods to create a specialised methodology) belong to this matrix.
For the completeness sake matrix #1 should be defined to the extent that the above functions can be identified. The requisite methods need to be specified and (if possible) paradigmatic models should be incorporated.
