CCM Quality Management Principles 3 — Questions and Answers
Question 1: The Plan-Do-Check-Act (PDCA) cycle is most closely associated with which quality management concept?
- Cost-benefit analysis
- Continual improvement (Correct answer)
- Earned value management
- Risk transference
Correct answer: Continual improvement
PDCA, developed by Deming, is a cyclical framework for continual improvement by planning changes, implementing them, checking results, and acting on findings.
Question 2: Which document formally defines the quality standards and inspection procedures applicable to a construction project?
- Project charter
- Quality Management Plan (Correct answer)
- Organizational breakdown structure
- Risk register
Correct answer: Quality Management Plan
The Quality Management Plan describes quality standards, inspection checkpoints, roles and responsibilities, and procedures for the project.
Question 3: Statistical Process Control (SPC) in construction quality is primarily used to:
- Determine contract award criteria
- Monitor process variation over time and detect out-of-control conditions (Correct answer)
- Calculate critical path durations
- Assess subcontractor financial stability
Correct answer: Monitor process variation over time and detect out-of-control conditions
SPC uses statistical methods and control charts to monitor ongoing processes and distinguish normal variation from special causes requiring intervention.
Question 4: A cause-and-effect diagram (fishbone or Ishikawa diagram) is used in construction quality to:
- Plot defect frequency over time
- Identify and organize potential causes of a quality problem (Correct answer)
- Track material deliveries
- Sequence inspection activities
Correct answer: Identify and organize potential causes of a quality problem
The Ishikawa diagram visually maps potential causes of a defect across categories such as materials, methods, machines, and manpower.
Question 5: During construction, 'quality surveillance' refers to:
- Security monitoring of the construction site
- Ongoing observation of work activities to ensure compliance with quality requirements (Correct answer)
- Reviewing subcontractor invoices for accuracy
- Inspecting final deliverables only
Correct answer: Ongoing observation of work activities to ensure compliance with quality requirements
Quality surveillance involves continuously observing construction activities in progress to verify that procedures and requirements are being followed.
Question 6: What is the primary purpose of a pre-construction quality meeting with subcontractors?
- To negotiate lower subcontract prices
- To communicate quality expectations, submittal requirements, and inspection procedures before work begins (Correct answer)
- To review the subcontractor's tax records
- To assign overtime scheduling
Correct answer: To communicate quality expectations, submittal requirements, and inspection procedures before work begins
Pre-construction quality meetings align all parties on quality standards, submittals, testing, and inspection hold points before work commences.
Question 7: Which concept describes a systematic examination of a quality management system to determine whether activities comply with planned arrangements?
- Quality control inspection
- Quality audit (Correct answer)
- Acceptance sampling
- Benchmarking
Correct answer: Quality audit
A quality audit is a structured, independent review of a quality system or process to verify conformance with standards and identify improvement opportunities.
