Defining Stakeholder Roles and Influence

A stakeholder is anyone who can affect or is affected by a project’s outcome. This influence can come from decision power, hands-on involvement, or simply being impacted by the final results. Stakeholders might shape goals, provide resources, approve deliverables, or rely on what the project produces.

To recognize who qualifies, teams need to look at how much a person’s work, interests, or responsibilities interact with the project. Someone becomes a stakeholder when their success or challenges are linked to the progress or completion. Understanding this principle helps identify everyone whose expectations must be considered, even before detailed planning begins.^[1]

Each stakeholder connects to a project through two dimensions that define their involvement: role and interest. The role describes what a person is responsible for, how they contribute, or what decisions they make. The interest shows what motivates them, what results they care about, and how those results affect their own goals.

For example, a product manager may have the role of defining priorities and guiding development. Their interest is in creating a product that meets user needs and supports business success. A customer has no official project role but a high interest in how the final product improves their experience.

Understanding the difference between these two dimensions helps teams see why people react differently to the same event. A stakeholder with limited authority can still hold a strong influence if the project affects them directly. Someone with high authority may have less emotional investment in specific details. By separating what people do from what they care about, teams gain a more accurate picture of who needs to be involved and why.^[2]

Stakeholders can be grouped by where they operate in relation to the organization. Internal stakeholders work within the company that owns or manages the project. They include people such as executives, department leads, project owners, designers, and engineers. Their influence usually comes from access to resources, knowledge of internal processes, and alignment with company goals.

External stakeholders operate outside the organization. They can be clients, customers, suppliers, investors, funders, regulators, or community representatives. Their influence often comes from expectations, market power, or dependence on the project’s outcomes. Internal groups tend to focus on delivery and strategy, while external ones often evaluate impact, value, and compliance. Recognizing both views helps build a realistic picture of how different interests interact in a single project.

Not all stakeholders are involved in a project in the same way or to the same degree. Primary stakeholders are the people or groups who have a direct role in shaping decisions, providing input, and approving work. They often include project owners, senior managers, decision-makers, or key contributors whose actions strongly influence success. Their participation is continuous and essential from start to finish.

Secondary stakeholders, in contrast, have an indirect but still meaningful connection. They may include supporting departments, customer-service teams, end users, or partner organizations. While they are not involved every day, they are the ones teams should not forget at key moments such as discovery, launch, or periods of change. These groups are affected by the outcome or can offer insights that enrich decision-making. Their viewpoints can uncover risks, dependencies, or opportunities that core teams might miss.

Authority is the power to make decisions. Influence is the power to shape those decisions.

These two forms of power often overlap, but they work in different ways. Authority comes from a formal role and the decision rights attached to it. Executives, project owners, and department heads hold authority because they can allocate resources, set priorities, or approve outcomes.

Influence, on the other hand, comes from expertise, trust, or communication skills. Someone without a senior title may still guide direction by shaping opinions, offering critical insight, or being the person others rely on for clarity.

Recognizing both types of power helps explain why some people drive change while others simply follow procedure. Authority gives control; influence gives persuasion. Effective stakeholder management depends on balancing both so that formal leaders and informal influencers move in the same direction instead of working against each other.

Influence in an organization rarely moves in a straight line. Decisions pass through layers of hierarchy, but real impact often travels through relationships and collaboration. Formal structures, such as reporting lines and approval steps, define who controls key stages of a project. Informal networks, built on trust or experience, can redirect those same decisions behind the scenes.

A simple rule helps clarify the difference: when teams need a decision, they target the person with authority; when they need adoption, they target the people with influence.

Understanding these patterns makes it easier to predict how information and priorities move between levels. An executive may hold final authority, yet a specialist or team lead may shape what that decision becomes by gathering data, framing options, or offering the recommendation that leadership relies on.

After a major decision, it’s helpful to ask: Who gathered the data? Who framed the options? Who gave the recommendation? That’s where influence flowed. Mapping both the visible and informal paths of influence helps teams anticipate who needs to be aligned for the work to move forward smoothly.

Authority defines who can approve or stop work. Impact shows who’s most affected when that decision becomes reality.

People with the power to make decisions are not always the ones who feel the consequences. Authority comes from the ability to approve budgets, assign work, or halt progress. Impact reflects how strongly the project’s outcomes influence someone’s goals, workload, or results.

For example, an executive may approve funding but experience little day-to-day change. Meanwhile, a customer-support lead or a user community may see their routines, tools, or responsibilities shift immediately once the project goes live.

Distinguishing between authority and impact helps prevent blind spots. When decisions rely only on high-level perspectives, teams risk overlooking practical challenges or user realities. Bringing in those who experience the impact firsthand creates a more accurate picture of risks, needs, and opportunities long before issues surface.

Stakeholders rarely act in isolation. Their influence depends on how they connect, share information, and rely on one another to achieve results. Internal departments coordinate through shared goals, while external partners, clients, or regulators contribute through agreements, expectations, or oversight. These links form a network that defines how easily collaboration happens and how quickly problems reach resolution.

When relationships are open and consistent, information flows smoothly and decisions are easier to align. Strong collaboration between product, design, and engineering teams, for example, helps identify risks early and keeps delivery predictable. In contrast, weak or competitive ties often lead to delays, unclear ownership, and missed feedback loops. Recognizing these connection patterns allows teams to see where communication supports progress and where it needs reinforcement.

Viewing relationships as part of stakeholder influence reveals that success often depends on how people cooperate, not only on how much power they hold.

Influence inside organizations moves both vertically and sideways. Hierarchy determines who approves budgets or sets goals, but much of the project’s real direction is shaped in the middle layers, where strategy meets execution. Middle managers interpret leadership goals and turn them into priorities for teams. Specialists and team leads then decide how those priorities take form in practice, often shaping outcomes more than expected.

Informal influence also crosses layers through expertise, credibility, and relationships. A senior engineer or experienced designer may have no formal authority but can still steer major decisions by being trusted across departments. These cross-level interactions can strengthen alignment when communication is transparent, but they can also create tension when expectations differ between strategic and operational levels.

Understanding how influence moves through both official and informal channels helps teams spot where coordination breaks down. When top-level intent does not match what happens on the ground, the issue usually lies in how influence is transferred, not in the plan itself.
