Enterprise architecture is a recognized best practice for growing IT’s efficiency and effectiveness in supporting business. Despite this, the practice of EA itself has not always been efficient and effective. In many organizations, this has led to the EA function being formed, then dissolved, and then reconstituted as CIOs try to find the best way for the organization to get value from it. EA as a support function is not unique in this frequent flux—similar situations are found with enterprise PMOs, IT strategy, and process improvement efforts.
