Power-Interest Grid
A classification of stakeholders by their influence over a decision and their level of concern with it, used to allocate communication effort deliberately.
Architecture work fails on stakeholders more often than on technology, and the usual cause is uniform communication: everyone gets the same document, so the people who decide are under-engaged and the people who care are ignored.
The grid gives four strategies:
High power, high interest — manage closely. Involve them in shaping the decision, not in reviewing it afterwards. A senior stakeholder who first sees a design at approval will find objections, and they will be legitimate ones nobody asked about earlier.
High power, low interest — keep satisfied. Brief, outcome-focused updates. Detail actively annoys them, and their interest rises sharply if something goes wrong.
Low power, high interest — keep informed. Frequently the engineers and operators who will live with the result. Under-consulting them loses information and produces resistance during implementation.
Low power, low interest — monitor. Minimal effort, and re-check occasionally, because positions move.
Two refinements that matter more than the grid itself: identify the actual decision-maker, who is regularly not the person chairing the meeting; and find the blockers early — the person who can stop the work is worth a conversation before the design is finished, not after.
