A power and interest grid is a four-quadrant matrix that plots stakeholders based on two dimensions: how much power they hold over a project and how much interest they have in its outcome. First proposed by Aubrey Mendelow in 1991, it remains one of the most widely used tools in stakeholder management across project management, policy, and business strategy. The core truth about the grid is simple: not every stakeholder deserves the same amount of your attention, and this tool helps you decide who gets what.
How the Grid Is Structured
The grid is a 2×2 matrix with power on one axis and interest on the other. Each axis runs from low to high, creating four quadrants. Every stakeholder on a project, whether a person, team, department, or external organization, gets placed into one of those quadrants based on a judgment call about their influence and their stake in the work.
The four quadrants each come with a recommended engagement strategy:
- High power, high interest: Manage closely
- High power, low interest: Keep satisfied
- Low power, high interest: Keep informed
- Low power, low interest: Monitor
That’s the entire framework. Its appeal lies in its simplicity. You can sketch it on a whiteboard in under a minute, and anyone on your team can understand it without training.
What Each Quadrant Actually Means
High Power, High Interest
These are your key players. They have the authority to change the direction of the project and they care enough to use it. Think of a senior sponsor who controls the budget and checks in weekly. These stakeholders need frequent, substantive communication. You’re not just sending them status updates; you’re actively involving them in decisions, managing their expectations, and making sure they stay supportive. Losing their backing can stall or kill a project.
High Power, Low Interest
This quadrant requires caution. These stakeholders can influence the project significantly but aren’t paying close attention to it. A C-suite executive who approved the initiative but has moved on to other priorities is a classic example. The strategy is to keep them satisfied without overwhelming them with detail. The risk here is real: if they become dissatisfied for any reason, they have the power to intervene in ways that disrupt the project. Proactive, concise communication works best.
Low Power, High Interest
End users, customers, and front-line team members often fall here. They care deeply about the outcome but don’t have formal authority over decisions. These stakeholders should be kept adequately informed with regular updates. They’re likely to feel anxious about their lack of control, so transparency matters. One often-overlooked truth about this group: they can be extremely helpful with project details. Because they’re engaged and motivated, they’ll flag issues early, test assumptions, and advocate for the project within their own networks.
Low Power, Low Interest
Minimal effort is the guideline here. These stakeholders don’t have influence over the project and aren’t particularly invested in it. You still monitor them, because positions can shift, but you don’t spend significant resources on engagement. Periodic check-ins are enough to make sure nothing has changed.
Stakeholder Positions Change Over Time
One of the most important truths about the grid is that it represents a snapshot, not a permanent map. A stakeholder who starts in the low-power, low-interest quadrant can move to high power, high interest if they get promoted, if regulations change, or if the project suddenly affects their department. The grid only works if you revisit it regularly throughout the project lifecycle.
This means the initial mapping exercise at project kickoff is just the beginning. Effective teams reassess stakeholder positions at major milestones, after organizational changes, and whenever the project scope shifts. A grid that sits untouched in a planning document from month one has limited value by month six.
Known Limitations of the Grid
The power and interest grid has real weaknesses, and understanding them is part of understanding the tool correctly.
The biggest criticism is subjectivity. Placing a stakeholder on the grid requires a judgment call about their power level and interest level, and different team members will often disagree. There’s no standardized scoring system built into the framework, which means two project managers mapping the same stakeholder group could produce very different grids.
The grid also oversimplifies. Researchers have pointed out that grouping stakeholders into four broad categories can flatten important differences between individuals in the same quadrant. A regulator and a board member might both land in the high-power, high-interest box, but their motivations, communication preferences, and potential objections are completely different. The grid tells you to “manage closely” but doesn’t tell you how.
Another gap: the grid doesn’t capture stakeholder attitude. It tells you someone has power and interest, but not whether they support or oppose the project. A high-power, high-interest stakeholder who actively opposes your work requires a fundamentally different approach than one who champions it. Some practitioners address this by color-coding stakeholders as supportive, neutral, or resistant, but that’s an addition to the original framework, not built into it.
To address some of these shortcomings, Robert Newcombe proposed pairing the power/interest matrix with a power/predictability matrix. This second grid helps you assess how predictable each stakeholder’s behavior is, which is useful for risk planning. More complex models like Mitchell’s Salience Model add a third dimension, urgency, to create a richer picture of stakeholder priorities. These alternatives are worth considering when a simple 2×2 grid feels insufficient for the complexity of your project.
How to Get the Most Out of It
The grid works best when it’s treated as a living communication tool rather than a one-time planning exercise. Start by brainstorming every stakeholder you can identify, then place them on the grid as a team so you surface disagreements about who holds real power and who genuinely cares. That conversation alone is often more valuable than the finished grid.
Pair the grid with specific action plans for each quadrant. “Manage closely” is a label, not a strategy. For each stakeholder in that top-right quadrant, define what managing closely looks like in practice: weekly one-on-ones, inclusion in steering committee meetings, early review of deliverables. The same applies to “keep satisfied” and “keep informed,” both need concrete communication plans to be useful.
Set a schedule to review the grid. Monthly is a reasonable default for most projects. During each review, ask whether anyone has shifted quadrants due to organizational changes, evolving project scope, or new information. Move stakeholders on the grid accordingly and adjust your engagement approach.
Finally, keep the grid visible and shared. A stakeholder map locked in a project manager’s personal files doesn’t help the rest of the team make better decisions about who to loop into conversations, whose feedback to prioritize, or whose concerns to escalate. The grid’s greatest strength is its clarity, and that only works when everyone can see it.
