Read the first 7 Scope and WBS Development flashcards as text

  1. A project team uses the 100% rule when building their WBS. This means:

    Answer: The WBS captures 100% of the work defined in the scope and no more

    The 100% rule requires that the WBS captures all work necessary to complete the project and includes no work outside the project scope.

  2. A requirements traceability matrix links requirements to which of the following to ensure alignment throughout the project lifecycle?

    Answer: Business needs, WBS deliverables, and test cases

    The requirements traceability matrix links requirements from origin through business needs, deliverables, WBS components, and verification/validation activities.

  3. Which input to the Define Scope process provides guidance on how scope will be defined, validated, and controlled?

    Answer: Scope management plan

    The scope management plan describes how the project scope will be defined, developed, monitored, controlled, and validated.

  4. A project is constructing a hospital. The WBS includes 'Patient Ward' as a level-2 element. Level-3 elements include 'Electrical Systems' and 'Plumbing.' What decomposition approach is being used?

    Answer: Deliverable-based decomposition by physical location

    Decomposing by major deliverable or physical component (ward) into its subsystems (electrical, plumbing) is deliverable-based decomposition.

  5. A project manager wants to collect requirements from 200 geographically dispersed stakeholders efficiently. The BEST technique is:

    Answer: Questionnaires and surveys

    Questionnaires and surveys are the most efficient method for gathering structured data from large, geographically dispersed groups.

  6. What is the primary benefit of including a scope baseline in the project management plan?

    Answer: It provides a fixed reference for measuring scope performance and managing changes

    The scope baseline serves as the approved reference against which project scope execution is compared and change requests are evaluated.

  7. During a project review, an auditor finds that team members are completing work NOT listed in the WBS. What PMBOK process should have prevented this?

    Answer: Control Scope

    Control Scope monitors project and product scope status and manages changes to the scope baseline, preventing unauthorized work.
