A five-step process for understanding who affects your product decisions, what they want, and how to engage each — extending the basic Power-Interest grid with the dimension that actually predicts behaviour.
▸ Try the interactive toolAdvanced Stakeholder Mapping is a five-step process for understanding the people who affect or are affected by your product decisions, then planning a tailored engagement strategy for each. It extends the basic Power-Interest grid from Module 1 by adding the dimension that genuinely predicts behaviour: each stakeholder's attitude — are they a supporter, a blocker, or neutral?
Power and interest tell you who to pay attention to; attitude tells you how. A high-power, high-interest stakeholder who supports you needs different handling than an identical one who opposes you — the basic grid treats them the same, which is its key limitation. The five steps run from identifying stakeholders, through assessing power/interest/attitude, to planning a specific engagement strategy per stakeholder. The output isn't a static map but a tailored plan: who to convert, who to keep close, who to neutralise, who to simply keep informed.
Basic grid: power × interest (who to attend to). Advanced adds attitude (supporter / neutral / blocker) — which predicts how to engage. A high-power supporter and a high-power blocker need opposite strategies the basic grid can't distinguish.
The basic Power-Interest grid tells you who matters but treats supporters and blockers of equal power identically — missing the dimension that actually determines how you should engage them.
| The shortcut | What it costs | What it gives you instead |
|---|---|---|
| Power/interest without attitude | A high-power supporter and blocker get the same plan — wrongly. | Attitude tells you how to engage, not just whom. |
| Treating stakeholders generically | One engagement approach for all; fits none. | A tailored per-stakeholder strategy fits each. |
| Ignoring blockers until late | Opposition surfaces too late to address. | Mapping attitude surfaces blockers early, when convertible. |
| Static mapping | A map made once and never revisited as attitudes shift. | Treating it as a living plan keeps engagement current. |
List everyone who affects or is affected by your product decisions — not just the obvious ones. Missing a stakeholder is how opposition blindsides you later.
Use the basic grid: how much power does each have over your work, and how much do they care? This tells you who warrants attention.
For each, assess their stance toward your direction. This is the dimension that predicts behaviour: a powerful blocker is a very different problem than a powerful supporter.
For each stakeholder, decide the approach their power×interest×attitude calls for: keep powerful supporters close and active, convert or neutralise powerful blockers early, keep interested-but-low-power people informed.
Attitudes shift as the work progresses — a neutral becomes a blocker, a blocker is won over. Revisit the map regularly so the engagement plan stays current.
A PM used the basic Power-Interest grid and identified two high-power, high-interest stakeholders as equally important — 'manage closely,' the grid said for both. But the grid was blind to a crucial difference: one strongly supported the direction, the other quietly opposed it. Treated identically, the blocker's opposition festered unaddressed until it surfaced late and forcefully.
Adding the attitude dimension would have flagged it immediately: the powerful supporter needed to be kept close and活用 as an ally, while the powerful blocker needed early, deliberate engagement to convert or neutralise the opposition before it hardened. Same power, same interest, opposite strategies — a distinction the basic grid couldn't make but the advanced map made obvious.
The deliverable is a map of stakeholders by power, interest, and attitude, each with a tailored engagement strategy — revisited as attitudes shift.
| Power × Interest × Attitude | Strategy |
|---|---|
| High power, supporter | Keep close, activate as ally |
| High power, blocker | Engage early — convert or neutralise |
| High interest, low power | Keep informed and heard |
| Low power, neutral | Monitor lightly |
Advanced stakeholder mapping adds the dimension — attitude — that turns a map of who matters into a plan for how to engage them. A powerful supporter and a powerful blocker demand opposite strategies the basic grid can't tell apart.
The power-interest grid is genuinely useful for triage — it tells you where to spend attention — but it's silent on the question that actually drives engagement: is this person for me or against me? Attitude is what predicts behaviour, and it's what determines strategy. A high-power supporter is an asset to activate; a high-power blocker is a risk to manage early, while there's still time to convert them or neutralise the opposition. Conflating the two — as the basic grid forces you to — means either smothering an ally or, far worse, leaving a powerful opponent unaddressed until their opposition hardens and surfaces at the worst moment. Treating the map as living matters too, because attitudes shift: today's neutral is tomorrow's blocker or convert, and the engagement plan has to keep up.
Treats allies and opponents identically. Add the attitude dimension.
Each stakeholder needs a strategy fit to their power, interest, and attitude.
Unaddressed opposition hardens. Surface and engage blockers early.
Attitudes shift. Revisit the map and update the plan regularly.
It adds attitude to the basic grid (Module 1, Tool 15).
The map says who and how; archetypes (Tool 05) say what behaviour pattern to expect.
Engagement strategies become the standing cadence (Tool 06).
Engaging stakeholders draws on your influence sources (Tool 01).
Take two stakeholders you'd both rate high-power, high-interest. On the basic grid they look identical. Now add attitude — is each a supporter, neutral, or blocker?
Describe how your engagement strategy for the two should differ, given the attitude difference the basic grid missed.
If the powerful supporter and powerful blocker end up with opposite strategies, you've seen exactly what the attitude dimension adds — and why the basic grid alone leads you to mishandle one of them.
