Which document serves as a guide for the execution and control of a project?

The project plan serves as a comprehensive guide for the execution and control of a project. It outlines the project's scope, objectives, timelines, resources, and tasks necessary to achieve the desired outcomes. The plan acts as a roadmap that helps project managers and teams understand their roles, responsibilities, and the sequence of activities involved in completing the project successfully. By providing details such as work breakdown structures, scheduling information, and resource allocations, a project plan enables teams to monitor progress, make informed decisions, and effectively manage changes throughout the project lifecycle.

In contrast, while a change log records modifications made to the scope, schedule, or resources, it does not provide the overarching structure needed for execution and control. A project report offers insights into the project's status and performance but is more focused on communication rather than guiding execution. A risk matrix identifies potential risks and assesses their impact but lacks the detail needed for overall project management. Thus, the project plan is essential for directing and controlling the various elements that contribute to successful project delivery.
