Stakeholder mapping is the process of identifying and visually analyzing everyone who affects or is affected by a project. In Six Sigma, it starts in the Define phase of DMAIC. It helps teams understand who holds power, who has high interest, and how to engage each person effectively. Without it, even technically sound projects can fail due to resistance, miscommunication, or lack of support.

What Is Stakeholder Mapping?
Stakeholder mapping is a structured process. You identify, analyze, and visually chart everyone connected to your project.
A stakeholder is anyone who affects or is affected by a project’s outcome. That includes sponsors, process owners, frontline staff, customers, suppliers, and senior leadership.
ProjectManager.com defines it this way: “Stakeholder mapping is a visual process. It charts each stakeholder for your project, product, or anything with stakeholders to show who can influence the work you’ll be doing.”
A completed stakeholder map shows each person’s level of power and interest. It helps teams decide how to communicate with each group. And it prevents the costly mistake of ignoring someone who can block progress.
Why Stakeholder Mapping Matters: The Data
Skipping stakeholder mapping carries a measurable cost.
According to PMI research cited in the PM Study Circle’s 2025 analysis of PMI data, weak stakeholder engagement and poor communication remain among the top causes of project failure. The same research notes that projects without formal change management processes are 35% more likely to exceed costs or miss deadlines.
The Standish Group’s research, cited by ClickUp (2024), puts the project failure rate at 65% across industries.
TeamStage’s 2024 analysis of PMI data adds a direct finding: 62% of successfully completed projects had supportive sponsors. Stakeholder engagement is listed as the most valuable project management process in that dataset.
These numbers make the case plainly. Projects with strong stakeholder management succeed more often. Projects that skip it fail more often.
In Six Sigma, where the goal is permanent, measurable process improvement, failing due to human factors is avoidable. Stakeholder mapping is how you avoid it.

Who Counts as a Stakeholder?
In Six Sigma projects, stakeholders fall into two broad groups.
Internal stakeholders:
- Project Champion or Sponsor
- Process Owner
- Black Belt or Green Belt leading the project
- Yellow Belts and team members
- Department managers whose processes will change
- Finance team members who will validate savings
- IT teams when system changes are involved
- Frontline staff who perform the process being improved
External stakeholders:
- Customers whose experience the project affects
- Suppliers whose inputs feed the process
- Regulators when compliance is a factor
- Partners or vendors connected to the work
Not every project has every type. Your first task is to list every individual or group with a stake in the outcome. Include people who might resist the change. Include people whose cooperation you need.

The Power-Interest Grid: The Core Tool
The most widely used stakeholder mapping tool is the Power-Interest Grid.
It is also called Mendelow’s Matrix. Aubrey L. Mendelow, a professor at Kent State University, introduced it in 1991 at the Second International Conference on Information Systems in Cambridge, Massachusetts.
The matrix places each stakeholder on a two-axis grid:
- Power: the ability to influence project outcomes, decisions, or resources
- Interest: the degree of concern a stakeholder has about the project’s success or failure
Plotting both axes creates four quadrants. Each quadrant requires a different engagement strategy.
| Quadrant | Power Level | Interest Level | Engagement Strategy |
| Manage Closely | High | High | Fully engage throughout the project |
| Keep Satisfied | High | Low | Provide regular updates; involve in key decisions |
| Keep Informed | Low | High | Communicate frequently; seek input |
| Monitor | Low | Low | Observe; minimal active engagement needed |
The most under-managed quadrant is “Keep Satisfied.” High-power, low-interest stakeholders feel safe to ignore until they suddenly care. At that point, they have the power to disrupt the project and no existing relationship to draw on.
The lesson: build those relationships before you need them.
Stakeholder Mapping Inside the DMAIC Framework
Stakeholder mapping is not a standalone exercise. It runs through every phase of DMAIC.
Define Phase:
This is where stakeholder mapping begins. You identify all stakeholders during Define. You assess their power and interest levels. You document them in a stakeholder register.
According to lean6sigmahub.com (2025), project leaders should “identify initial stakeholders and secure sponsorship” during the Define phase. The project champion and process owner need to be engaged and aligned before any data is collected.
You also build your SIPOC here. The Suppliers and Customers columns of your SIPOC are a natural starting point for stakeholder identification.
Measure Phase:
Your measurement plan depends on people. The staff who operate the process must trust the data collection effort. Frontline workers who feel excluded often reject the process or provide inaccurate data.
Engage process workers during Measure. Explain why you are collecting data. Acknowledge their experience and knowledge. Their buy-in makes data collection more accurate and builds trust for the Improve phase.
Analyze Phase:
Root cause analysis requires input from subject matter experts. These are often mid-level stakeholders in the “Keep Informed” quadrant.
Bring them into fishbone diagram sessions and cause-and-effect analysis work. Their insight reduces the risk of identifying false root causes.
Improve Phase:
The Improve phase is where resistance peaks. You are asking people to change the way they work.
The Lean 6 Sigma Hub notes (2025): “Many Six Sigma projects fail not because of technical deficiencies but due to human factors. Without proper stakeholder engagement, even the most statistically sound solutions can face resistance.”
Your stakeholder map tells you exactly who is most likely to resist and why. Address their concerns directly. Involve them in solution design where possible.
Control Phase:
The process owner must accept ownership of the new standard. Monitoring responsibilities must be assigned clearly.
If the process owner is not engaged and committed, the improvement will not hold. Control phase work depends entirely on human accountability.

How to Create a Stakeholder Map in Six Sigma Projects
Use the following six steps to build a stakeholder map for any Six Sigma project.
Step 1: List every potential stakeholder.
Start broadly. Include anyone who touches the process, makes decisions about resources, or will be affected by the outcome. Use your SIPOC, project charter, and interviews with the Champion to build this list.
Step 2: Assess each stakeholder’s power level.
Power is the ability to affect project outcomes. It includes formal authority, budget control, and the ability to block or accelerate progress. Rate each stakeholder as high or low power relative to this project.
Step 3: Assess each stakeholder’s interest level.
Interest is the degree to which a person cares about this project’s success or failure. High-interest stakeholders are directly affected. Low-interest stakeholders may have limited impact on their daily work. Rate each stakeholder as high or low interest.
Step 4: Plot stakeholders on the Power-Interest Grid.
Place each stakeholder in one of the four quadrants: Manage Closely, Keep Satisfied, Keep Informed, or Monitor. Do this as a team. Different team members often have different perceptions of stakeholder positions. Discuss disagreements openly.
Step 5: Define an engagement strategy for each quadrant.
The quadrant determines the approach. Document how often you will communicate with each stakeholder. Define the format (one-on-one meetings, team updates, written reports). Assign responsibility for each relationship.
Step 6: Update the map throughout the project.
Stakeholder positions shift. A process owner who starts as “Keep Informed” may move to “Manage Closely” once the Improve phase begins. Review the map at each phase gate. Adjust your engagement strategies when positions change.
Common Mistakes in Stakeholder Mapping
The following errors are common in Six Sigma projects.
Only mapping upward. Teams often focus on Champions and senior leaders. They overlook frontline operators and middle managers. These groups frequently determine whether solutions actually get implemented.
Treating the map as a one-time document. A stakeholder map created in Define and never revisited quickly becomes inaccurate. Stakeholder positions change as the project progresses.
Confusing position with relationship. Knowing where someone sits on the grid does not mean you understand their concerns. Stakeholder mapping tells you who to engage. Stakeholder interviews tell you what they care about.
Ignoring potential resistors. Teams sometimes leave out stakeholders who seem hostile to the project. This is exactly backward. Resistors need more attention, not less. Understanding their concerns early prevents problems later.
Stakeholder Mapping and the Six Sigma Project Charter
The project charter is the foundation document of every Six Sigma project.
It identifies the project sponsor, the Black Belt, and the process owner. It defines the problem statement, goal, scope, and timeline.
Your stakeholder map extends from this document. Every person named in the charter is a stakeholder. Every department named in the scope boundary is a source of additional stakeholders.
Build your stakeholder map alongside your project charter in the Define phase. The two documents work together.
Key Takeaways
- Stakeholder mapping identifies and analyzes all individuals affected by a project, helping teams engage effectively.
- It showcases each stakeholder’s power and interest, which aids in communication and prevents project failure.
- Using the Power-Interest Grid, teams can categorize stakeholders into four quadrants and tailor engagement strategies accordingly.
- Skipping this mapping can lead to costly project delays, as poor stakeholder engagement is a major cause of failure.
- In Six Sigma, stakeholder mapping begins in the Define phase and must be updated throughout the entire project.
FAQ: What Is Stakeholder Mapping?
What is stakeholder mapping in simple terms?
Stakeholder mapping is the process of identifying everyone who affects or is affected by a project and charting them visually. You assess each person’s level of power and interest in the project outcome. The result is a map that guides how you communicate with and engage each group throughout the project. In Six Sigma, this work begins in the Define phase of DMAIC.
What is the Power-Interest Grid?
The Power-Interest Grid, also called Mendelow’s Matrix, is a two-axis chart that places stakeholders into four quadrants based on their power and interest. It was introduced by Aubrey L. Mendelow in 1991. The four quadrants are: Manage Closely (high power, high interest), Keep Satisfied (high power, low interest), Keep Informed (low power, high interest), and Monitor (low power, low interest). Each quadrant requires a different engagement strategy.
When should you do stakeholder mapping in a Six Sigma project?
Stakeholder mapping begins in the Define phase of DMAIC. You identify stakeholders alongside your project charter and SIPOC. However, the map should be updated throughout the entire project. Stakeholder positions shift as the project progresses from Measure through Control. Review and update the map at each phase gate.
Why do Six Sigma projects fail due to stakeholder issues?
Many Six Sigma projects fail not because of technical problems but because of human resistance and lack of support. Lean 6 Sigma Hub notes that technically sound solutions can still face resistance if the right people are not engaged throughout the project. PMI research confirms that weak stakeholder engagement is a top cause of project failure. Frontline staff who are excluded during Define often resist changes in the Improve phase.
What is the difference between stakeholder mapping and stakeholder analysis?
Stakeholder mapping identifies who the stakeholders are and places them visually on a grid. Stakeholder analysis goes deeper. It assesses each stakeholder’s specific interests, concerns, motivations, and potential impact. Mapping tells you who to engage and how intensively. Analysis tells you what they care about and how to address their concerns. In practice, both are done together as part of the same process.
How does stakeholder mapping connect to SIPOC?
SIPOC is a Define-phase tool that maps Suppliers, Inputs, Process, Outputs, and Customers. The Suppliers and Customers columns identify external stakeholders directly. Process steps identify internal stakeholders such as operators and department leads. SIPOC is a strong starting point for building your stakeholder list before placing individuals on the Power-Interest Grid.
