GMP stands for Good Manufacturing Practice, & the term is used globally for managing the control and management of manufacturing, testing and overall quality of pharmaceutical products. It defines certain guidelines that talks about the quality assurance approach. GMP certification ensures that products are produced following the quality standard norms.
Joint Commissioner is authorized by Commissioner, Food & Drug Administration, to sign & issue the certificates under the WHO-GMP certification scheme. GMP certification deals with issues like documentation, record keeping, personnel qualifications, sanitation, cleanliness, equipment verification, sanitation, complaint handling, and process validation.
GMP requirements are not peculiar in any sense instead they are open ended and easy to implement also these requirements give liberty to the manufacturer to decide individually how to efficiently implement the necessary controls.
