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.
Explanation
Control Quality is a Monitoring and Controlling process that deals with inspecting actual deliverables and work results. It involves measuring specific project results against quality standards to determine whether they conform to requirements. The process uses techniques such as inspection, testing, statistical sampling, and the seven basic quality tools.\n\nWhen deliverables do not meet quality standards, the Control Quality process generates change requests, defect repairs, and updates to lessons learned. Verified deliverables, which have been confirmed as correct, are an output of this process and become inputs to the Validate Scope process where the customer formally accepts them.\n\nControl Quality is reactive in nature compared to Manage Quality. It identifies defects after work has been performed and ensures those defects are corrected before deliverables are presented to the customer. However, the data gathered during Control Quality also feeds back into Manage Quality for process improvement.
Key Points
- •Part of the Monitoring and Controlling process group
- •Inspects deliverables, not processes
- •Outputs include verified deliverables and quality control measurements
- •Verified deliverables feed into the Validate Scope process
Exam Tip
Control Quality produces verified deliverables. Validate Scope produces accepted deliverables. Control Quality happens first, then Validate Scope. This sequence is frequently tested.

Manage Quality
Manage Quality is the process of translating the quality management plan into executable quality activities that incorporate the organization's quality policies into 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.
Statistical Sampling
Statistical sampling involves selecting a representative subset of a population for inspection, allowing the project team to draw conclusions about overall quality without inspecting every item.
Check Sheets
A check sheet is a structured form used to collect and organize data in real time at the location where the data is generated, often used as a preliminary step for other quality analysis tools.
Histograms
A histogram is a bar chart that shows the distribution of data by grouping measurements into intervals (bins), revealing the shape, central tendency, and variability of the data.
Pareto Chart (80/20 Rule)
A Pareto chart is a type of bar chart in which the categories are ordered by frequency from highest to lowest, with a cumulative line showing the running total percentage, based on the 80/20 principle.
