Inspection is one of the most important parts of quality control. Inspection involves measuring, examining, and testing products, process and services against specified segments to determine conformity.An inspection determines if the material or item is in quantity and condition, and if it conforms to the applicable or specified requirements.If inspection is done properly, it helps to great extent in ensuring proper control on quality of the materials and products.

  • Inspection is generally divided into three categories; (1) Receiving inspection, process inspection, and (3) Final inspection.In quality control, the role of inspection is to verify and validate the variance data.
  • The use of inspection has been evident throughout the history of organised production.During the early years of manufacturing,inspection was used to decide whether a workers job or a product met the requirements.It was not done in a systematic way, but worked well when the volume of production was resonantly low. However, as organisations being larger,the need for more effective operations became apparent.
  • In 1911 Frederick W. Taylor helped to satisfy this need.One of taylor's concepts was clearly defined task performed under standard conditions. Inspection was one of these tasks and was intended to ensure that no faulty product left the factory or workshop.

  • Is carried out at the end of the productions process and relies on specially trained inspectors
