Just a quick note. I ran across this interesting post from Leo de Sousa, an Enterprise Architect in the Higher Education setting, who uses a Capability Maturity Model to help him to measure and drive EA maturity.
This is one of the most common ways to use measurement to improve Enterprise Architecture. As I pointed out in my post on measurement, EA in every organization needs not only to have a balanced scorecard but also to participate in a balanced scorecard in order for the value to be measured and rewarded. In many ways, a maturity model is a balanced scorecard. Doing better at "maturity" means that your measurement improves. Driving to improve that measure motivates change.
I'll blog again on this topic. I just wanted to share Leo's excellent post.
