Project Management Project Scope and Quality 3 — Questions and Answers
Question 1: A control chart shows data points consistently trending toward the upper control limit over 8 consecutive measurements. This pattern indicates:
- Random variation within acceptable limits
- A process that is out of control (Correct answer)
- Acceptable common cause variation
- A process performing exactly as designed
Correct answer: A process that is out of control
The rule of seven states that seven or more consecutive points trending in one direction signal a non-random, out-of-control process.
Question 2: Which technique involves breaking down deliverables into progressively smaller components until they can be reliably estimated and managed?
- Rolling wave planning
- Decomposition (Correct answer)
- Prototyping
- Benchmarking
Correct answer: Decomposition
Decomposition is the technique used to subdivide project deliverables and work into smaller, more manageable components within the WBS.
Question 3: A project manager and team are reviewing project deliverables against the scope baseline to determine if they are complete and correct. This activity belongs to which process?
- Control Quality (Correct answer)
- Validate Scope
- Plan Quality Management
- Control Scope
Correct answer: Control Quality
Control Quality is the process of monitoring and recording results of quality activities to assess performance and ensure deliverables meet requirements.
Question 4: The concept of 'fit for use' in quality management refers to:
- Meeting all documented requirements exactly
- Satisfying actual needs of the customer or end user (Correct answer)
- Passing all defined acceptance tests
- Conforming to international quality standards
Correct answer: Satisfying actual needs of the customer or end user
Joseph Juran defined quality as 'fitness for use,' meaning the product must satisfy the real needs of those who use it.
Question 5: Which of the following is NOT typically an input to the Control Scope process?
- Scope baseline
- Work performance data
- Requirements traceability matrix
- Risk register (Correct answer)
Correct answer: Risk register
The risk register is not a primary input to Control Scope; key inputs include the scope baseline, work performance data, and requirements traceability matrix.
Question 6: A customer requests a change that expands the project scope. After approval through the change control process, the project manager should update:
- Only the project schedule
- The scope baseline and related project documents (Correct answer)
- Only the WBS
- Only the project charter
Correct answer: The scope baseline and related project documents
Approved scope changes require updates to the scope baseline and any affected project documents such as the schedule, budget, and WBS.
Question 7: Prevention costs and appraisal costs are both components of:
- Cost of quality
- Cost of conformance (Correct answer)
- Cost of non-conformance
- Sunk cost
Correct answer: Cost of conformance
Cost of conformance includes prevention costs (training, process improvement) and appraisal costs (testing, inspections) to avoid defects.
