The initiating process group is the one that occurs at the beginning of the project. It involves defining the project scope, objectives, and deliverables, obtaining the project authorization, identifying the key stakeholders, and establishing the project manager’s authority. The initiating process group helps to set the vision and direction of the project, and aligns it with the strategic goals of the organization. The initiating process group also ensures that the project is feasible, viable, and desirable, and that it has the necessary support and resources to proceed. References:
