A power/interest grid answers one question: how much does this person matter, and how much are they paying attention. It says nothing about whether they want you to succeed. Plenty of consultants build a clean four-quadrant map, place someone in "manage closely," and still get blindsided — because high power and high interest describe a stakeholder's position, not which way they're leaning.
Position and sentiment are two different axes
Position is structural: how much authority someone has, and how closely they're watching. Sentiment is relational: are they an advocate, neutral, or actively skeptical of your work. A standard grid only plots position. That's useful for deciding how much attention someone deserves, but it tells you nothing about the tone of that attention — and the tone is what determines whether their attention helps you or hurts you.
A high-power, high-interest stakeholder who's an advocate is your best asset on the account. The same position occupied by a skeptic is your biggest risk. Both sit in the same box on a standard grid. Only sentiment tells them apart.
Add a third dimension instead of a new grid
You don't need to throw out the power/interest grid — you need to tag each stakeholder on it with a sentiment reading. Three buckets are enough for most engagements:
- Advocate: Actively wants the engagement to succeed. Defends you when others question the work, volunteers information, makes introductions without being asked.
- Neutral: No strong pull either way. Will go along with whatever the group decides. Persuadable, but not currently persuaded.
- Skeptical:Doubts the value of the work, the vendor, or the approach. Doesn't have to be loud about it — a skeptic who says nothing in meetings is still a skeptic.
Read sentiment the same way you read power: from behavior, not from what people tell you directly in a room. Does this person loop you into information proactively, or only answer what's asked? Do they reference your work approvingly to peers, or route around it? Did they attend the kickoff and then quietly stop showing up to anything optional?
Why the combination changes your engagement plan
The standard grid tells you to "manage closely" anyone with high power and high interest. Sentiment tells you what managing closely should actually look like for that specific person.
Two stakeholders, same quadrant, opposite plan:
VP of Ops — high power, high interest, advocate.She pushed for this engagement internally and checks in weekly because she wants updates to share upward. Managing closely here means feeding her wins she can repeat to her boss — she's doing sales work for you inside the org for free.
Director of Finance — high power, high interest, skeptical.He also checks in weekly, and asks just as many questions as the VP. But his questions are about cost overruns and whether this could have been done in-house. Managing closely here means over-documenting deliverables and ROI before he asks, and not treating his engagement as enthusiasm — it's scrutiny.
A grid with position alone tells you to invest equal effort in both. It won't tell you that one relationship needs ammunition and the other needs armor.
Sentiment moves faster than position
Someone's formal power rarely changes mid-engagement — titles and budget authority are sticky. Sentiment shifts constantly, often for reasons that have nothing to do with your work: a reorganization, a bad quarter, a competing initiative eating their attention. A neutral stakeholder can turn skeptical after one missed deadline that wasn't even yours. That's exactly why sentiment needs to be tracked as its own field, checked at every renewal or check-in, rather than assumed to hold steady once you've set it.
The stakeholders worth watching most closely aren't the ones with the strongest current opinion — they're the high-power neutrals, because a neutral with real authority is the one swing vote that can move an account either direction.
Position and sentiment together give you the full picture the grid alone can't. If you haven't built the base layer yet, the Stakeholder Mapping Tool handles the power/interest plotting — sentiment is the field to add on top of it for each person.
