Aim: To understand the Perform Quality Control process
In the project context, quality is not only defined as delivering the right thing at the right time and at the right cost, but also delivering to customer expectations. As such, you, the project manager, have to ensure that the required metrics, tolerances, reports, and checklists are in place to ensure a quality-prone execution and delivery sandbox is in place. The perform quality control process enables the project manager to assess the level of quality of the project’s deliverables and take any required action.
The table below shows the inputs, tools and, techniques, and outputs for the perform quality control process.
| Perform Quality Control | ||
|---|---|---|
| Inputs | Tools & Techniques | Outputs |
| Project management plan Quality metrics Quality checklists Work performance information Approved change requests Deliverables updates Organizational process assets | Cause and effect diagrams Control charts Flowcharting Histogram Pareto chart Run chart Scatter diagram Statistical sampling Inspection Approved change requests review | Quality control measurements Validated changes Validated deliverables Organizational processes assets updates Change requests Project management plan Project document updates |
Some of the tools available to the project manager in controlling quality are
• The Ishikawa (also called the fishbone or cause and effect) diagram
• Control charts, such as the ones available using Three or Six Sigma
• Six Sigma—99.99% defect free or about 0.002 defective parts per million
• Three Sigma—99.73% defect free or about 2,700 defective parts per million
• Pareto chart (the 80/20 rule)
• Statistical sampling, such as the ones used in the standard audit processes
