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.

Plan Quality Management
Plan Quality Management is the process of identifying quality requirements and standards for the project and its deliverables, and documenting how the project will demonstrate compliance with those requirements.
Control Quality
Control Quality is the process of monitoring and recording the results of executing quality management activities to assess performance and ensure project outputs are complete, correct, and meet customer expectations.
Quality Management Plan
The quality management plan is a component of the project management plan that describes how applicable quality policies, procedures, and guidelines will be implemented to achieve the quality objectives of the project.
Control Charts
A control chart is a graph used to study how a process changes over time, displaying data points plotted against upper and lower control limits to determine whether the process is in statistical control.
