The organisation chart shows who reports to whom. It rarely shows who decides. Leaders who understand the real map of influence around a decision are far more likely to get it right — and get it done.
Every important decision in a company passes through a formal process: a proposal, a committee, a board vote. And every experienced leader knows that the formal process is only part of the story. Before a proposal reaches the board, its fate has often already been shaped by conversations, alliances and objections that never appear in the minutes.
Understanding this informal map of power is not cynicism. It is a condition for leading effectively. Leaders who ignore it are regularly surprised by resistance they did not see coming. Those who understand it can anticipate concerns, build support and avoid unnecessary conflict.
Formal authority and real influence
Formal authority is defined by statutes, shareholder agreements, delegations and organisation charts. Real influence follows other lines.
- A minority shareholder may carry disproportionate weight because of a historical relationship with the founder.
- A long-serving director may shape the views of newer board members.
- A chief financial officer may effectively hold a veto through control of information and relationships with lenders.
- A family member without a formal role may influence the controlling shareholder more than any director.
- An investor’s representative may be guided by an investment committee that never attends the board.
None of this is necessarily improper. But leaders who navigate only the formal structure will consistently misjudge how decisions are really made.
Building a power map
A power map is a simple but disciplined exercise. For each significant decision, it asks:
- Who decides formally? Which body or individual has the authority to approve or block?
- Who influences the decision-makers? Whose opinion will they seek, consciously or not, before deciding?
- What does each person want? Not only their stated position, but their underlying interests: financial, reputational, personal, institutional.
- What does each person fear? Loss of influence, exposure, criticism, financial risk, a change in their own role.
- How are they connected? Which alliances exist, which tensions, which historical grievances?
The output is not a document for circulation. It is a private tool for thinking about how to bring a decision to a successful conclusion.
Using the map well
A power map is useful only if it changes how leaders act. Several practices follow naturally from it.
Consult before proposing. Key influencers who are consulted early, and whose concerns are reflected in the proposal, are far more likely to support it. Those who discover a major proposal in the board pack often oppose it on principle.
Address interests, not just arguments. A director who resists a proposal may not be persuaded by better analysis if the real concern is loss of influence or a reputational risk. Understanding the interest makes it possible to address it.
Sequence conversations. The order in which people are approached matters. Securing the support of a respected voice before broader discussion can shape how others receive the proposal.
Anticipate coalitions. Resistance often forms quietly, through alliances between people who share a concern. Identifying potential coalitions early allows leaders to engage before positions harden.
The limits of influence work
Mapping power is not a substitute for a sound proposal. Influence can help a good decision pass; it should not be used to force through a bad one. Boards that feel manipulated tend to react strongly, and trust, once lost, is difficult to rebuild.
There is also a governance dimension. Informal influence that systematically bypasses the board, or concentrates power in individuals without accountability, is a warning sign. Part of a chair’s role is to ensure that informal dynamics support the formal governance rather than undermine it.
When the map changes
Power maps are not static. They shift with changes in ownership, leadership transitions, new board appointments, the entry of an investor or a crisis that alters who is trusted. Leaders who rely on an outdated understanding of influence are particularly vulnerable during such transitions.
New chief executives, incoming chairs and investors entering a company benefit especially from mapping power early, before they make decisions that depend on the support of people they do not yet understand.
The value of an outside view
Leaders are often too close to the dynamics around them to see them clearly. They have their own relationships, loyalties and blind spots. An independent advisor, with no position in the organisation and experience of similar situations, can help test the map: who has been overlooked, which interests have been misread and where resistance is likely to come from.
Seeing the room as it is
Effective leaders combine two forms of understanding: a clear view of the substance of a decision and a realistic view of the people who will shape its outcome. The first ensures that the decision is right. The second ensures that it is adopted and implemented.
The organisation chart shows the structure of a company. The power map shows how it really works.
