Quality Assurance and Quality Control

Quality Control: “A part of quality management focused on fulfilling quality requirements”.

Quality Assurance: “A part of quality management focused on providing confidence that quality requirements will be fulfilled.”

Quality Assurance (QA) refers to the process used to create the deliverables, and can be performed by a manager, client, or even a third-party reviewer. Examples of quality assurance include process checklists, project audits and methodology and standards development. Quality Control (QC) refers to quality related activities associated with the creation of project deliverables. Quality control is used to verify that deliverables are of acceptable quality and that they are complete and correct. Examples of quality control activities include inspection, deliverable peer reviews and the testing process.

Implementing QA and QC, first properly define “Quality” and then the role that each (QA and QC) play in achieving quality. Quality Assurance is the planned and systematic activities implemented within the quality system that can be demonstrated to provide confidence that a product or service will fulfill requirements for quality. Whereas quality control is defined as the operational techniques and activities used to 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 plan whereas quality control on the other hand is the physical verification that the product conforms to these planned arrangements by inspection, measurement.

Quality Control just measures and determines the quality level of products or services. It is a process itself. Quality assurance is a complete system to assure the quality of products or services. It is not only a process, but a complete system including also control. It is a way of management.
