Stakeholder Mapping: How to Identify and Engage Key Decision Makers

Tuesday, 1 September 2026

For professionals working in procurement, project management or organisational change, the ability to map stakeholders accurately is not optional. It is one of the strongest predictors of whether an initiative will get the support it needs to succeed. The Project Management Institute (PMI) confirmed this in its 2025 Pulse of the Profession report, finding that 91 to 94% of project professionals consider stakeholder management a foundational capability, regardless of whether they face scope, budget or timeline pressures.That statistic carries particular weight in Australia’s public sector, where multi‑agency governance structures mean that decisions are rarely made by one person alone.

How the power‑interest grid works

The most practical starting point for stakeholder mapping is to assess each stakeholder along two dimensions: how much power they hold over the outcome and how much interest they have in it. This is the basis of the power‑interest grid, a framework first introduced by Aubrey Mendelow in 1991 and built on the foundational stakeholder theory set out by R. Edward Freeman in his 1984 book Strategic Management: A Stakeholder Approach. Freeman defined a stakeholder as any group or individual that can affect, or is affected by, the achievement of an organisation’s objectives. Mendelow’s contribution was to turn that broad concept into something a team could draw on a single page and use in a meeting.

The grid produces four quadrants. Stakeholders with high power and high interest need to be managed closely, because they can shape outcomes and they care enough to act. Those with high power but low interest should be kept satisfied, as they have the authority to intervene if they become displeased but are unlikely to engage unless provoked. Low‑power, high‑interest stakeholders should be kept informed, because they are engaged and vocal even though their direct authority is limited. Finally, low‑power, low‑interest stakeholders simply need to be monitored. Spending equal effort across all four groups wastes time on people who neither want nor need close attention, while neglecting those who do.

The grid is only useful if it reflects current reality. Stakeholders move. A regulator who sits in the “keep satisfied” quadrant on a routine project may shift to “manage closely” the moment a compliance issue surfaces. An end user who was content to observe may become deeply interested if the project directly changes their workflow. Treating the grid as a living document, reviewed at each phase gate or milestone, is what separates functional stakeholder mapping from a one‑off exercise filed away after kickoff.

How to identify the decision makers who matter most

In procurement, supply chain and project environments, the real decision makers are rarely confined to a single function or seniority level. A procurement manager may need sign-off from a finance director, technical input from an engineer, legal clearance from a compliance team and political support from a senior executive, all before a contract can proceed. Missing any one of these people creates blind spots that surface later as delays, objections or rework.

The Chartered Institute of Procurement & Supply (CIPS) distinguishes between three categories of stakeholders in procurement: internal stakeholders such as budget holders, department heads and senior leadership; external stakeholders such as suppliers, regulators and community groups; and connected stakeholders, individuals or organisations that have a contractual relationship with the organisation. Each group holds a different form of influence, and each requires a different engagement strategy. CIPS also notes that influencing is now one of the top five soft skills most in demand for procurement and supply chain professionals.

Identification works best when it follows a structured approach. List everyone affected by the decision or its outcome. Ask who has authority to approve, block or alter the direction. Consider who shapes opinion informally, because the person who does not sign the contract but who advises the person who does can be just as influential as the formal decision maker. Finally, plot each name on the power‑interest grid. The resulting map will tell you where to concentrate your engagement and who you can afford to keep at arm’s length.

Stakeholder mapping in the Australian context

In Australia’s public sector, governance and accountability requirements make multi‑stakeholder decision making the norm rather than the exception, and stakeholder mapping is a formal expectation. The Australian Public Service Commission (APSC) provides practical guidance that formalises what good practice looks like. The APSC advises public servants to identify and map stakeholders based on their interest in and influence on taskforce objectives, determine which issues require stakeholder input, develop strategies for each group and evaluate the effectiveness of engagement as work progresses.

The broader APS Framework for Engagement and Participation sets out four modes of engagement: share, consult, deliberate and collaborate. Not every stakeholder needs or expects the same level of involvement. A senior departmental secretary may need a concise briefing on commercial outcomes, while an end‑user group may want to be consulted in detail about how a new system will change their daily work. Matching the mode of engagement to the stakeholder’s position on the power‑interest grid is what turns a stakeholder map into a workable engagement plan.

For professionals working in Australian state or federal government procurement, this is not abstract theory. Audit bodies including the Australian National Audit Office routinely examine whether agencies have appropriately identified and engaged stakeholders during procurement and contract management processes. Getting stakeholder mapping wrong creates governance risks that attract scrutiny long after the project is complete.

Common mistakes that undermine stakeholder engagement

The most frequent failure is treating stakeholder mapping as a one‑off exercise completed during project kickoff, then filed away and never revisited. Projects evolve, people change roles, organisational priorities shift, and the stakeholder map that was accurate in week one can become dangerously misleading by month three. A second common error is treating all stakeholders with equal priority. When every stakeholder gets the same level of communication, the people who genuinely need close management receive too little attention, while those who simply need monitoring receive too much.

Another trap is confusing seniority with influence. A mid‑level technical specialist who writes the evaluation criteria for a tender may have more practical influence over the outcome than a senior executive who signs the final approval. Mapping should capture actual influence, not just formal authority. Finally, many professionals default to a single communication channel for all stakeholders. A detailed written briefing may suit a finance director, but a quick face‑to‑face conversation may be far more effective with an operational manager who is time‑poor and prefers verbal updates. Effective stakeholder engagement requires adapting both the message and the medium to the audience.

Building your stakeholder engagement capability

Stakeholder mapping produces a diagram, but turning that diagram into better outcomes requires a set of practical skills: the ability to influence without formal authority and the judgement to read a room when circumstances shift.

AcademyGlobal (AG) has been helping professionals develop these capabilities since 2004. AG’s faculty bring practical experience across procurement, project management, negotiation, leadership and contract management, drawn from senior roles in both commercial organisations and government agencies. AG delivers programs for public sector, private sector and not‑for‑profit organisations across Australia and internationally, with a strong focus on building the skills that turn analysis into action.

AG’s Influencing to Achieve Better Outcomes program directly addresses the capability gap between knowing who your stakeholders are and being able to engage them effectively. Participants learn how to map stakeholders and influence pathways, adapt communication styles to different audiences, build trust and credibility and respond constructively to resistance. It is a practical program designed for managers, project professionals, procurement practitioners and anyone who needs to gain support, build alignment or encourage action from others.

Frequently asked questions

What is stakeholder mapping and why is it important?

Stakeholder mapping is the process of identifying all individuals and groups with an interest in or influence over a project or decision, then categorising them by their level of power and interest. It is important because it allows professionals to focus engagement effort where it will have the greatest effect, reducing the risk of missed approvals, unexpected opposition or misaligned expectations.

What is the difference between a stakeholder map and a stakeholder engagement plan?

A stakeholder map identifies who is involved and plots them by power and interest. A stakeholder engagement plan goes further by setting out how each stakeholder or group will be communicated with, how often and through which channels. The map is the diagnostic step. The engagement plan is the action step.

How do you identify key decision makers in a large organisation?

Start by listing everyone affected by the decision or its outcome. Then identify who has formal authority to approve or block progress. Next, look for informal influencers: the people who shape opinion, advise decision makers or control access to resources. Plot each person on a power‑interest grid to determine who needs close management and who can be kept informed at a distance.

How often should a stakeholder map be updated?

At minimum, review the stakeholder map at each project phase gate or major milestone. You should also update it whenever there is a significant change in scope, team membership, organisational structure or external conditions. A stakeholder map that is only created once at kickoff will quickly become unreliable.

What skills do you need for effective stakeholder engagement?

Effective stakeholder engagement requires influencing and persuasion skills, the ability to adapt communication styles to different audiences, active listening, empathy, negotiation capability and the confidence to manage resistance constructively. These skills can be developed through structured training such as AcademyGlobal’s Influencing to Achieve Better Outcomes program.
