Plot everyone who touches your product by how much power they hold and how much they care — so you spend your engagement energy where it actually changes outcomes.
▸ Try the interactive toolThe Power-Interest Grid is a 2×2 stakeholder-mapping framework that positions everyone who interacts with — or is affected by — your product along two axes: Power (their ability to influence decisions, approve budgets, or block progress) and Interest (how much they actively care about what you're building).
The result is a map that tells you how to engage each person: who to manage closely, who to keep satisfied, who to keep informed, and who to monitor with minimal effort. The point isn't to rank people's importance — it's to allocate your finite communication energy so the high-power, high-interest people are never surprised and the low-power, low-interest ones don't drain your week.
High power, high interest → manage closely · High power, low interest → keep satisfied · Low power, high interest → keep informed · Low power, low interest → monitor
PMs lead without authority, so stakeholder energy is a scarce resource. Spend it uniformly and you'll over-serve the indifferent while blindsiding the people who can kill your project.
| The shortcut | What it costs | What it gives you instead |
|---|---|---|
| Treating all stakeholders equally | Equal energy to everyone means too little for the people who matter. | The grid concentrates effort where power and interest are highest. |
| Blindsiding power | A high-power stakeholder surprised by a decision can block it. | “Manage closely” and “keep satisfied” ensure the powerful are never ambushed. |
| Drowning in the indifferent | Long updates to people who don't care waste everyone's time. | “Monitor” and “keep informed” right-size the communication. |
| Ignoring quiet blockers | A low-interest but high-power person can derail a launch late. | Mapping power explicitly forces you to plan for them in advance. |
Internal and external: execs, eng leads, design, sales, support, key customers, economic buyers, even adjacent teams. Don't pre-filter — capture all of them.
Power: can they approve, fund, or block? Interest: do they actively care about this work? Rate both high/low — be honest, not flattering.
Map every stakeholder to one of the four cells. Watch for the dangerous one: high power, currently low interest — they can become a late blocker.
Manage closely (involve, co-decide), keep satisfied (brief, don't overload), keep informed (regular updates), monitor (light touch). Match cadence to cell.
Power and interest move — a reorg, a new exec sponsor, a launch nearing. Re-map periodically; the grid is a living document, not a one-time artifact.
A PM mapped stakeholders before a launch and found a senior leader in the high-power / low-interest cell — someone who'd shown no engagement but controlled the budget. Standard plan would have left them on a generic mailing list.
Instead the PM gave them a tailored, brief “keep satisfied” update ahead of each milestone. When a competing project later tried to claim the launch's resources, that leader — already informed and bought-in — defended it. An un-engaged version of the same person might have shrugged and let it go.
The deliverable is the populated 2×2 with an engagement strategy noted for each person.
| Quadrant | Strategy | Cadence |
|---|---|---|
| High power, high interest | Manage closely — involve in decisions | Frequent, two-way |
| High power, low interest | Keep satisfied — brief, don't overload | Milestone summaries |
| Low power, high interest | Keep informed — they're allies | Regular updates |
| Low power, low interest | Monitor — light touch | As needed |
Stakeholder energy is finite and the temptation is to spread it evenly. The grid's whole job is to make you spend it unevenly — concentrated where power and interest are high, minimal where they're low.
The highest-leverage insight is usually the high-power, low-interest quadrant: people who could block or rescue your work but currently aren't paying attention. Left alone, they surface late as a surprise veto. Engaged early with the right light-touch cadence, they become the sponsor who defends you when resources get contested. The grid earns its keep by making you notice them in advance.
A passionate but powerless advocate can't unblock a budget. Rate the axes independently.
High-power, low-interest stakeholders are the classic late blocker. Plan for them deliberately.
Long updates to “monitor”-quadrant people waste their time and yours.
Positions shift with reorgs and milestones. Re-map; a stale grid misleads.
The grid sets who and how often; the comms-cadence and exec-briefing tools (Module 6) set what and how.
The grid maps power and interest; archetypes (Module 6) add personality and motivation to each person on it.
Knowing who's in “manage closely” shapes how you frame and sequence a roadmap review.
Influence, political capital, and navigating organisational power build directly on this map.
Pick a current project and list five people who affect or care about it. Rate each on power (can they fund/approve/block?) and interest (do they actively care?), and place them in a quadrant.
Find anyone in high-power / low-interest. That's your at-risk relationship — the person most likely to surprise you later.
The stakeholder you're not currently talking to, who quietly holds power, is almost always the one worth an hour this week.
