Which quality metrics are commonly used in CQM?

• A. NCR closure time, defect rates, test pass rates, and schedule adherence.
• B. NCR closure time, defect rates, test pass rates, punch list items, and schedule adherence.
• C. Defect rates and punch list items only.
• D. Monthly safety meeting counts.

Answer: (B)

Quality metrics in construction quality management focus on how well the project controls defects, verifies performance, and progresses toward turnover. The best set includes NCR closure time, defect rates, test pass rates, punch list items, and schedule adherence because each metric covers a key area: NCR closure time shows how quickly nonconformances are resolved; defect rates measure how often defects occur; test pass rates reflect how well testing verifies compliance with specifications; punch list items capture remaining work needed before final acceptance; and schedule adherence ties overall quality performance to timely completion and readiness for turnover. Monthly safety meeting counts, while important for safety culture, don’t directly measure construction quality performance, and other options miss one or more essential quality-tracking elements.
