The quality of a product, service or process should always be checked in project management. This is the reason why the quality control measurements are used by project managers to document the results of the control quality activities.
The quality control measurements are used to analyze as well as evaluate the quality of the different processes involved in a project against the standards of the organization or on the requirements specified during the project management planning.
This measurement can also be used to compare the processes that are used in making the measurements. It is also used to validate the actual measurement to determine their degree of correctness.
Since quality control measurements are documented results, it is crucial that they be captured in formats that are specified through the Plan Quality Management process. It is also important to take note that this particular document is also an important input for the Perform Quality Assurance. It is one of the inputs needed to generate change requests, project document updates, project management plan updates and the organizational process assets updates. This is to ensure that the quality standards, as well as operational definitions, are satisfied.
This term is defined in the 5th edition of the PMBOK.
