Chapter 9Technical Analysis Drives End-State Architecture Structural Decomposition

There is no shortage of technical implementations and installed products in a production environment. And there is no dearth of sub-architectures in a sizeable end-state architecture. The design styles could be spotted anywhere. But with increasing product deployments, the variations of sub-architecture styles are growing as well. Not all patterns, however, of enterprise asset arrangements on a network could be classified. In fact, many formations are not even understood by production engineers. This inability to categorize sub-architectures only increases operational confusion and creates business continuity perils.

The chief technical analysis mission then would be to decompose an end-state architecture into sub-architectures buy classifying them. This process may be applied to a proposed enterprise grand design or an operating production landscape. Ascertaining how the various products and technologies carry business functionality would then be a good starting point. In other words, the end-state decomposition effort ought to be driven by technical capabilities.

Remember, here we do not pursue sub-architecture classification and end-state architecture decomposition from a business perspective.

Technical capabilities demonstrate the power of the technologies driven by enterprise architecture to provide solutions. Only a technical analysis could delve into sections of an end-state architecture ...
