Enterprise architecture: decide with a target, not with a diagram
An exhaustive map has never been enough to make a decision. What is most often missing is the link between the target and the trade-off.
Set a target architecture, break it into realistic steps and settle application choices with arguments everyone understands.

An accurate map is not enough to make a decision. Leadership needs a target that states choices: which applications to keep, merge or retire, in what order, and at what cost.
A map of applications, flows and contracts, built with your teams from what actually runs.
Two or three possible paths, each with its costs, risks and dependencies written down.
Stable intermediate states that each deliver something, rather than a big-bang switch.
Short, enforceable architecture principles that committees use to decide.
