The Project Management Plan is the document that describes how the project will be executed, monitored and controlled, and closed. It serves as the central reference for all project operations, integrating and consolidating all subsidiary plans into a coordinated and actionable blueprint for delivery.
This plan defines how scope, schedule, cost, quality, resources, communication, and risks will be managed, ensuring consistency, accountability, and alignment with organizational objectives.
