Validation is a tool of quality assurance which provides confirmation of the quality in equipment system, manufacturing process, software and testing methods. Validation of the individual step of manufacturing processes is called the process validation. The concept of validation was first proposed by two Food and Drug Administration(FDA) officials, Ted Byers and Bud Loftus, in the mid-1970s in order to improve the quality of pharmaceuticals Assurance of product quality is derived from careful attention to number of factors including selection of quality parts and materials, adequate product and process design, control of the process, and in process and end product testing.
