8.1. GAUGING MATURITY
Organizations gauge the maturity of their EA/SOA adoption for one of two fundamental reasons:
Reactive benchmarking to determine where the organization is with respect to other business units or enterprises
Proactive strategy and planning to align EA/SOA initiatives with objective criteria and business goals
Inevitably, gauging the organization's maturity leads to the examination of formal maturity models. The reactive/proactive perspectives do not materially change the crafting or populating of the models; they simply change the metrics, reporting, and interpretation of them. Generally, either the available models are standalone, SOA-specific models or they depend on and define a mapping to CMMI (which is great if you are working with an organization that is familiar with this approach).
