Quality assurance is performed during which phase of a project?

While quality is controlled throughout the project, quality *assurance* specifically focuses on the *processes* during execution, distinct from the broader controlling phase which also monitors overall project performance.

Although quality control (monitoring specific results) happens throughout execution and controlling, quality *assurance* is specifically about the *process* of building quality into the work, which is active during execution.

Quality assurance (QA) involves auditing the quality requirements and the results of quality control measurements to ensure that proper quality standards and operational definitions are being applied. This process predominantly occurs during the execution phase, as the project team performs the work, to ensure that the correct processes are followed to produce high-quality deliverables.

The planning phase involves defining the quality management plan and requirements, but the actual performance of quality assurance-auditing processes-occurs when the work is actively being performed.
