Quality Metrics
Quality metrics are specific, measurable attributes of project deliverables or processes that describe what will be measured and how it will be measured during quality management activities.
Explanation
Quality metrics are an output of the Plan Quality Management process and serve as a foundation for both Manage Quality and Control Quality. They define the specific measurements that the project team will use to evaluate whether deliverables and processes meet quality standards. Examples include defect density, test coverage percentage, on-time delivery rate, mean time between failures, and customer satisfaction scores.\n\nEffective quality metrics are specific, measurable, and directly tied to project quality objectives. They establish clear thresholds and tolerances so that the team knows when a measurement is within acceptable limits and when corrective action is needed. Metrics should be defined during planning and communicated to all relevant stakeholders.\n\nDuring execution and monitoring, actual measurements are taken and compared against the planned quality metrics. These quality control measurements become data points for analysis in processes like Control Quality. The results help the team make evidence-based decisions about whether deliverables are acceptable and whether processes need improvement.
Key Points
- •Output of Plan Quality Management
- •Define what will be measured and acceptable thresholds
- •Used as inputs to Manage Quality and Control Quality
- •Must be specific, measurable, and tied to quality objectives
Exam Tip
Quality metrics define what to measure. Quality control measurements are the actual results of those measurements. Know the difference between the planned metric and the actual measurement.

Cost Performance Index (CPI)
Cost Performance Index (CPI) is an EVM efficiency metric that measures cost performance as the ratio of earned value to actual cost: CPI = EV / AC.
Schedule Performance Index (SPI)
Schedule Performance Index (SPI) is an EVM efficiency metric that measures schedule performance as the ratio of earned value to planned value: SPI = EV / PV.
Earned Value Management (EVM)
Earned Value Management (EVM) is a methodology that integrates scope, schedule, and cost data to assess project performance and progress objectively.
