The Learning Curve
It is in the interest of the organization for the Enterprise Architect to start the AEAR by basing the functional and linkage metrics on the current metrics of the organization for three reasons. First, it lends a feeling of continuity. The leadership and management see the data they are expecting; though the Enterprise Architect should expect to suppliment the current metrics with additions for those functions and, in particular, links, without current metrics. Second, using the current metrics provides an immediate baseline of data for those metrics that do not need immediate revision--yes, there will always be some good metrics. Third, inserting the current metrics into an architectural structure, especially if linked to good visualization tools, will allow the leadership and management to "see" at least some of the poor metrics--poor from the standpoint that they do not measure what they are supposed to measure.
