Inspection is one of the most important parts of quality control.

Inspection involves measuring, examining and testing products, process and services against specified requirements to determine conformity.

An inspection determines if the material or item is in proper quantity and condition.

If inspection is done properly, it helps to a great extent in ensuring proper control on quality of the materials and products Inspection is generally divided into three categories: 1) Receiving inspection, 2) In-process inspection and 3) Final inspection. In quality control, the role of inspection is to verify and validate the variance data.

In 1911, Fredrick W Taylor helped to satisfy this need. One of the Taylors concepts was clearly defined tasks performed under standard conditions.

Inspection was one of these tasks and was intended to ensure that no faulty product left the factory or workshop, Focuses on the product and the detection of problems in the product, involves testing every item to ensure that it complies with product specifications, is carried out at the end of the production process and relies on specially trained inspectors.

This movement led to the emergence of a separate inspection department. An important new idea that emerged from this new department was defect prevention, which led to quality control.
