Differences between QA&QC

Quality Assurance, and Quality Control

 Quality Assurance: It is defined as “All the plan and  systematic activities implemented within the quality system that can be demonstrated to provide confidence that a process used to fulfill requirement of product or service will fulfill requirements for quality.”

Quality Assurance is fundamentally focused on planning and documenting those processes to assure quality including things such as quality plans and inspection and test plans.

Quality Control: It is defined as “the operational techniques and activities used to fulfill requirements for quality”.

Quality Control on the other hand is the physical verification that the product conforms to these planned arrangements by inspection, measurement etc.
