At what point of the project life cycle, does a stakeholder have the heaviest influence on the project?

The initiating stage is the first phase of the project life cycle, where the project is defined, its purpose is established, and the initial project scope is determined. At this stage, stakeholders play a crucial role in shaping the project by providing input, defining project requirements, and identifying the project's strategic goals and objectives. (Stakeholders are individuals or groups who are directly or indirectly affected by the project or have a vested interest in its outcome. They can include project sponsors, clients, end users, project team members, management, regulatory bodies, and other relevant parties.)
