(2) Project managers in central IT would like help from EA in improving solution architectures delivered by their projects, to make their projects more technically sustainable. To meet this expectation, the EA practice should:

Scenarios such as the ones above arise continuously in the evolution of an EA practice. With each change comes a reassessment of the EA practice: Is our scope still clear? Are we still engaged with the right stakeholders? Do we need to deliver and measure value in new ways? Do we have the right team? The maturity model provides structure for identifying these questions and keeping the EA practice on track to increasing maturity.
