Aim: To understand the Perform quality assurance Process
Quality assurance is the process of auditing quality requirements and the results from quality control measurements that are used to ensure the project employs all processes needed to meet requirements. It differs from quality control, which is monitoring specific project results to ensure they meet quality standards.
Even though the Perform Quality Assurance is part of the Executing phase and Quality Control is part of Monitoring & controlling, the output of Perform Quality Control is used as an input to Quality Assurance. Don’t get confused here. Both these activities happen hand in hand and the segregation between the Execution and Controlling phases is very slim.
The table below shows the inputs, tools and techniques, and outputs for the perform quality assurance process.
|Perform Quality Assurance|
|Inputs||Tools & Techniques||Outputs|
Project management plan
Work performance information
Quality control measurements
Plan quality and perform quality control tools and techniques
Organizational process asset updates
Project management plan updates
Project document updates
The benefits of continuous improvement include reduced waste and reduction in non–value-added processes, leading to increased efficiency and effectiveness.
Work performance information is an important input to quality assurance. Work performance information is defined as data on the status of project schedule activities. It can include such items as technical performance measurements, project deliverables status, schedule progress, and costs incurred. This information can be used in audits, quality reviews, and process analysis. Other important inputs to quality assurance include approved change requests and quality control measurements. Approved change requests are any change requests that have been processed through the change management process and approved by the proper authority. Quality control measurements are the results of quality control activities.
1. Memorize and understand all the inputs to quality assurance.
2. The tools used in quality planning and quality control can also be used in quality assurance
Along with the tools used in quality planning and quality control, two other tools in quality assurance are quality audits and process analysis. Quality audits are independent reviews to verify compliance with quality standards. For example, a review team looks at control charts to determine if the processes were being controlled properly and if proper actions were taken when processes fell outside control limits. Process analysis supports continuous improvement as explained in the previous section.
Root cause analysis is a technique to examine a problem, determine the underlying cause of the problem, and implement corrective action to prevent further occurrence.
The application of quality assurance might result in changes to the project, which take the form of change requests or recommended corrective action. Updates are made to the project management plan and/or organizational process assets.
