A board of directors rarely validates a direction without the discreet approval of certain middle managers. The CEO’s signature is not always enough to lock in a strategic decision; less visible players, such as the CFO or the HR manager, sometimes hold unexpected blocking power.
In some organizations, a technical project manager can influence the trajectory of a major investment, well beyond their official scope. The displayed governance scheme often masks the reality of decision-making circuits, where each choice depends on fluctuating alliances and informal networks.

Who really makes decisions in a company? Decoding visible and hidden roles
Forget the clichéd image of the all-powerful company boss: the decision-making mechanics play out on a much larger chessboard. Identifying the true circuits of influence involves going beyond the CEO figure to explore the diversity of decision-making actors who operate in both shadow and light. The main decision-makers are not limited to top management. The business decision-maker often controls the budget, the approver makes the final call, and the evaluator analyzes and validates the proposed choices.
Around each project revolves a range of roles, of which here are the main ones:

- Champion: this internal supporter advocates for the solution, lays the groundwork, and accelerates buy-in.
- Domino: a cross-influencer, they subtly guide the positions of other stakeholders.
- Purchasing manager, CFO, site HR: their technical, financial, or social validation conditions the next steps of the project.
The decision-making dynamic is rooted in these interactions, where the official hierarchy intertwines with real informal forces. A steering committee can make decisions, but buy-in depends on intermediate relays, sometimes invisible on the organizational chart. The executive must embody the strategy to senior managers, who then pass it on to middle managers. Everyone plays their part, deciphers signals, navigates alliances, and seeks the right tempo. And let’s not forget the role of key collaborators: their departure can crack the structure, forcing the company to implement solid plans to retain and replace these strategic profiles.

Mapping key actors: understanding influence circuits for better collaboration
Managing a project is not just about setting deadlines or running meetings. For project management to bear fruit, it is essential to create a complete map of the stakeholders and their areas of influence. The project manager cannot just organize: they must identify who really matters, measure their weight, and anticipate their reactions. This approach, far too often overlooked, can transform the course of a project, from the initial action plan to its realization.
| Actor | Weight in decision | Type of influence |
|---|---|---|
| Project manager | High | Coordination |
| Stakeholders | Variable | Direct or indirect |
| Support from decision-makers | Determining | Strategic |
A poor reading of power dynamics can derail the return on investment or cause unexpected blockages. Researchers from MIT Sloan have shown that strategic alignment, or its absence, durably shapes the trajectory of an organization. Consider the sudden disappearance of a leader, like Steve Jobs at Apple: the question of succession and influence transfer becomes urgent. Conversely, meticulous preparation, like that conducted at Total after the loss of Christophe de Margerie, reduces the risk of abrupt disruption.
Influence networks are constantly reshaping, with each new initiative, each crisis, each delicate negotiation. Mapping these forces means identifying supporters, opponents, and mediators, then adapting one’s strategy to move forward without getting lost in complexity. In this labyrinth, those who see clearly always maintain an edge.
