Quality control is a process by which entities review the quality of all factors involved in production. This approach places an emphasis on three aspects:[citation needed]

The quality of the outputs is at risk if any of these three aspects is deficient in any way.

Quality control emphasizes testing of products to uncover defects, and reporting to management who make the decision to allow or deny the release, whereas quality assurance attempts to improve and stabilize production, and associated processes, to avoid, or at least minimize, issues that led to the defects in the first place.[citation needed]

Total quality control

"Total quality control" is a measure used in cases where, despite statistical quality control techniques or quality improvements implemented, sales decrease. If the original specification does not reflect the correct quality requirements, quality cannot be inspected or manufactured into the product. For instance, the parameters for a pressure vessel should include not only the material and dimensions, but also operating, environmental, safety, reliability and maintainability requirements.

Quality control in project management

In project management, quality control requires the project manager and the project team to inspect the accomplished work to ensure that it's aligned with the project scope[3]. In practice, projects typically have a dedicated quality control team which focuses on this area.[citation needed]
