Every successful project depends on managing the right people, not just the right tasks. The Power-Interest Grid helps you map stakeholders based on how much influence (power) they hold and how much they care (interest) about your project.
In this guide, you’ll learn how to build and use the grid step-by-step, apply engagement strategies for each quadrant, and access an editable interactive Stakeholder Grid Template to start mapping your own network.
By the end, you’ll know exactly who to manage closely, who to keep informed, and how to communicate effectively with all stakeholders.
What Is a Power-Interest Grid?
A Power-Interest Grid (also called a Mendelow Matrix) is a visual framework for categorising project stakeholders based on their influence and engagement level.
Definition and Purpose of the Power-Interest Grid
The power-interest grid helps project teams analyse stakeholder dynamics to prioritise communication and resources.
By plotting stakeholders according to their power (ability to influence project outcomes) and interest (level of concern or involvement), project managers can decide who to engage deeply and who to monitor lightly. This ensures engagement efforts focus where they create the most value.
It’s not about ignoring anyone. It’s about recognising that different stakeholders need different levels of attention, and your time matters. When you map people clearly, you stop over-communicating with those who don’t need it and under-communicating with those who do.
Typical Use Cases of a Power-Interest Grid
The Power-Interest Grid becomes particularly useful in these situations:
- Planning communication strategies
- Prioritising stakeholders for engagement
- Preparing governance reports
- Supporting stakeholder analysis in project initiation
- Integrating into project management frameworks (PMBOK, PRINCE2, Agile roles)
Components of the Power-Interest Grid
The grid has two axes (Power and Interest), creating four quadrants representing how to manage each stakeholder group.
Power-Interest Grid Quadrants Explained
Each quadrant tells you how to allocate your attention and communication effort:
1. High Power / High Interest: Manage Closely – Engage regularly through meetings and updates. These are your sponsors, senior leaders, or key decision-makers who care deeply about the outcome and can shape it directly.
2. High Power / Low Interest: Keep Satisfied – Share concise updates focused on high-level outcomes. They have authority but limited bandwidth, so respect their time with clarity and brevity.
3. Low Power / High Interest: Keep Informed – Provide open communication and feedback opportunities. These stakeholders are invested emotionally or operationally but lack formal authority.
4. Low Power / Low Interest: Monitor – Track occasionally for awareness; minimal communication needed. A brief status note now and then keeps them in the loop without overloading anyone.
Benefits of Using the Power-Interest Grid for Stakeholder Mapping
Mapping stakeholders visually has tangible advantages for clarity, communication, and proactive management.
Key Benefits
The grid offers practical value in several areas:
- Prioritises effort where it matters most.
- Highlights potential sources of conflict or resistance.
- Helps identify stakeholder champions early.
- Supports transparent communication planning.
- Enables focused reporting for leadership or sponsors.
- Adapts easily to Agile or Waterfall environments.
- Encourages accountability within the project team.
When you know where each person sits on the grid, you stop guessing about who needs what. You communicate with intention, not habit. That clarity reduces noise and builds trust across the entire project network.
How to Create a Power-Interest Grid Step-by-Step
Follow these clear steps to build your own Power-Interest Grid and make stakeholder management measurable and strategic.
Step 1: Identify Stakeholders
List all internal and external stakeholders: customers, sponsors, suppliers, regulators, and team members. Capture anyone with influence, authority, or interest. Don’t filter yet. At this stage, completeness matters more than precision.
Step 2: Assess Power and Interest
Evaluate each stakeholder’s authority, decision-making influence, and engagement level. Use interviews or historical data to determine where they sit. Ask yourself: Can they block progress? Do they care about daily updates or just outcomes?
Step 3: Plot on the Grid
Using a visual matrix or spreadsheet, map each stakeholder into one of the four quadrants. Colour-code or tag by department for easy reference. Keep it simple. The grid should clarify, not complicate.
Step 4: Develop Engagement Strategies
For each group, define how often and by what means you’ll communicate: reports, meetings, dashboards. Match the channel to the quadrant. High power stakeholders rarely want Slack pings.
Step 5: Monitor and Update
Review regularly. Roles and priorities shift as the project evolves. Update the grid at key milestones or governance reviews. A static grid becomes outdated fast, and outdated maps lead to miscommunication.
Power-Interest Grid Example for Stakeholder Mapping
Here’s an example of a simple Power-Interest Grid applied to a project launch scenario.
Sample Grid
Imagine you’re leading a website redesign project. Your stakeholders might map out like this:
Project: Website Redesign
Stakeholders:
• Sponsor (High Power / High Interest): Weekly review meetings. They control budget and direction, and they’re invested in success. Keep them close and informed early.
• Marketing Lead (High Power / Low Interest): Monthly dashboard summary. They have authority over go-live decisions but focus on outcomes, not process. A concise visual update works best.
• Design Team (Low Power / High Interest): Daily updates via Slack. They care deeply about the work but don’t control major decisions. Open channels keep morale high and feedback flowing.
• Customer Service Rep (Low Power / Low Interest): Quarterly status note. They’re affected indirectly but don’t need regular involvement. A light touch maintains awareness without creating noise.
This simple visual clarifies who needs what type of communication, reducing confusion and ensuring alignment throughout delivery. When everyone knows their role in the communication flow, you avoid both over-engagement and neglect.
Stakeholder Engagement Strategies by Power-Interest Grid Quadrant
Once stakeholders are mapped, use the grid to drive customised communication strategies for each quadrant.
Engagement Approach
Different quadrants call for different engagement rhythms and formats. Here’s how to tailor your approach:
• Manage Closely (High Power / High Interest): Schedule one-on-one briefings, use dashboards, provide early updates. These stakeholders shape decisions and care about progress. Give them visibility before issues become problems. Regular touchpoints build trust and alignment.
• Keep Satisfied (High Power / Low Interest): Focus on concise executive summaries and visual metrics. They want outcomes, not details. A single-page status update or a three-minute conversation respects their time while keeping them confident in your direction.
• Keep Informed (Low Power / High Interest): Share team newsletters, surveys, or open feedback channels. These people are your advocates and your eyes on the ground. Engage them authentically. Their enthusiasm and insight often surface risks or opportunities you’d otherwise miss.
• Monitor (Low Power / Low Interest): Maintain minimal but professional contact, like a quarterly digest. Don’t ignore them completely, but don’t burden them with updates they don’t need or want.
Each approach ensures resources are spent engaging those with real impact on success, not maintaining unnecessary communication volume.

Stakeholder Power vs Interest vs Influence: What’s the Difference in Project Management?
Power, interest, and influence are related but distinct dimensions of stakeholder analysis.
Comparison Overview
Understanding all three helps you see the full picture of stakeholder dynamics:
| Dimension | Definition | Example Metric |
|---|---|---|
| Power | Authority or ability to affect decisions | Budget control, approval rights |
| Interest | Level of concern or engagement | Project outcome impact |
| Influence | Degree of persuasion or advocacy | Informal leadership, expertise, relationships |
Power is formal. It’s written into org charts and job descriptions. Interest is emotional or operational. It’s about care and attention. Influence is social. It’s the person everyone listens to, even if they don’t sign off on anything.
Some stakeholders have all three. Others have one without the others. A junior team member might have high influence and high interest but no formal power. A distant executive might hold power but show little interest or influence day to day.
Understanding all three ensures your stakeholder strategy reflects both formal authority and informal influence.

FAQs on Power-Interest Grid
What’s the difference between Power-Interest and Power-Influence grids?
Power-Interest focuses on stakeholder concern and engagement. Power-Influence examines ability to sway others. Use Power-Interest for communication planning and Power-Influence for coalition building and advocacy strategies.
How often should a stakeholder grid be updated?
Update at major milestones, phase gates, or when roles change. Monthly reviews work for long projects. Agile teams might reassess each sprint. Stakeholder dynamics shift, so your grid should too.
Can Agile teams use Power-Interest mapping?
Absolutely. Map product owners, scrum masters, stakeholders, and users. It helps prioritise feedback loops and clarifies who attends sprint reviews. Agile thrives on transparency, and the grid supports that.
Who owns the stakeholder grid in a project?
Typically the project manager or business analyst. In Agile, it might be the product owner. Ownership ensures accountability, but the grid should be visible and shared across the team.
Should the grid be shared with all stakeholders?
Not always. Share it within the project team and governance groups. External sharing depends on culture and trust. Use judgment. Transparency builds trust, but labeling people publicly can backfire.
