A project team member is uncertain how many activities are required to complete a task. Which of the following documents should be referenced?

Key Performance Indicators (KPIs) are metrics used to measure performance and progress, not a document detailing the specific activities required for a task.

The Project Charter authorizes the project and provides high-level objectives and constraints, but it does not detail the specific activities needed to complete tasks.

The Work Breakdown Structure (WBS) is a key project document that breaks down the project deliverables into smaller, more manageable components, including work packages and the specific activities required to complete them. If a team member is uncertain about the activities needed for a task, consulting the WBS will provide the necessary detailed breakdown of work.

The Statement of Work (SOW) describes the scope, objectives, and deliverables of the work to be performed, but the WBS provides the granular decomposition of that work into activities.
