What Is Quality Control?
Quality control is the operational techniques and activities that are used to fulfill requirements for quality.
Quality control involves operational techniques and activities aimed both at monitoring a process and at eliminating root causes of unsatisfactory performance at relevant stages of the quality loop in order to result in economic effectiveness.
When one is referring to quality control, special care should be taken in describing what really is meant, so that confusion is avoided.
For example: Is manufacturing quality control the same as company-wide quality control?
Quality control focuses on and emphasizes the appraisal of quality as opposed to the planning of quality.
