Enterprise Architecture Value Model

Do not attempt to jump from your current position to Level 4 in a single organizational initiative. Architecture functions that attempt to take on horizontal ownership before they have built delivery credibility, engineering capability, and organizational trust find that the investment required exceeds their mandate and that the platforms they build are not trusted by the vertical portfolios they are supposed to serve. The right sequencing is the one the ladder implies: advance through the levels in order, building the organizational evidence and capability at each level that makes the next level achievable.

If your architecture function is at Level 1 or Level 2, identify one or two at-risk or high-risk initiatives where you can authorize the Level 3 engagement model — where you can give your architecture team real decision authority and measure it by delivery outcomes. The track record from those engagements becomes your organizational evidence for the Level 4 investment conversation. Simultaneously, identify the horizontal platform with the highest cross-portfolio demand and the lowest current governance quality in your enterprise. That is your first Level 4 ownership target. A well-chosen first platform, executed with engineering rigor and demonstrated cross-portfolio value, is more effective than an ambitious horizontal ownership strategy pursued across too many fronts simultaneously.
