Final answer:
The Project Schedule is the optimal document for finding detailed planned value (cost) for various periods of a project, as it includes cost and resource planning, unlike the Project Charter, Risk Register, or Stakeholder Analysis (C).
Step-by-step explanation:
The Project Schedule is the best place to find the planned value (cost) of different periods within a project. The Project Schedule outlines the timeline for tasks and milestones, and includes detailed resource and cost planning. While the Project Charter includes high-level information about the project including initial costs, scope, and high-level risks, it does not provide period-specific cost details.
The Risk Register is used for identifying, assessing, and managing risks, and does not detail cost planning. The Stakeholder Analysis identifies and analyzes project stakeholders but does not focus on budgeting.
The project schedule is the best place to find the planned value (cost) of different periods within the project. The project schedule is a timeline that includes all the activities and milestones of the project, along with their planned start and end dates. It also indicates the estimated cost for each activity and period within the project.
