CPC Project Scope Management 2 — Questions and Answers
Question 1: Scope validation is different from quality control because:
- Scope validation confirms acceptance of deliverables by stakeholders, while quality control checks correctness (Correct answer)
- Scope validation checks for defects and quality control checks for completeness
- They are the same process with different names
- Scope validation only occurs at project closure
Correct answer: Scope validation confirms acceptance of deliverables by stakeholders, while quality control checks correctness
Scope validation is stakeholder sign-off on completed deliverables, whereas quality control verifies they meet technical specifications.
Question 2: Which technique involves gathering requirements by observing end users performing their actual job tasks?
- Observation (job shadowing) (Correct answer)
- Brainstorming
- Focus groups
- Benchmarking
Correct answer: Observation (job shadowing)
Observation allows the coordinator to see firsthand how users work, revealing requirements they might not articulate in interviews.
Question 3: A requirements traceability matrix (RTM) is used to:
- Link requirements to their source and track them through the project lifecycle (Correct answer)
- Assign team members to requirements
- Schedule when requirements will be implemented
- Document approved scope changes
Correct answer: Link requirements to their source and track them through the project lifecycle
An RTM ensures every requirement can be traced to its business objective and to the deliverable that satisfies it.
Question 4: What is a work package in a WBS?
- The lowest level of the WBS where work can be scheduled, estimated, and assigned (Correct answer)
- A summary task at the top of the WBS hierarchy
- A grouping of all deliverables by phase
- The final deliverable of the project
Correct answer: The lowest level of the WBS where work can be scheduled, estimated, and assigned
Work packages are the smallest units in a WBS, detailed enough to estimate cost and duration and assign ownership.
Question 5: Which of the following is the BEST way to prevent scope creep?
- Establish a formal change control process and obtain written approval for all changes (Correct answer)
- Refuse all change requests from stakeholders
- Only allow changes at the end of each project phase
- Allow minor changes informally to keep stakeholders happy
Correct answer: Establish a formal change control process and obtain written approval for all changes
A formal change control process ensures every change is evaluated, approved, and tracked before being incorporated.
Question 6: When decomposing scope in a WBS, you should stop breaking down work when:
- The work can be reliably estimated, assigned to one owner, and completed within a reporting period (Correct answer)
- You have reached at least 10 levels of hierarchy
- Every work package is under one hour of effort
- The sponsor approves the breakdown
Correct answer: The work can be reliably estimated, assigned to one owner, and completed within a reporting period
Decomposition is sufficient when work packages are small enough to estimate, assign, and track without further breakdown.
