Good Manufacturing Practice (GMP) is a method for assuring that products are consistently manufactured and measured according to state criteria. It is intended to reduce the risks associated with any pharmaceutical product that cannot be discharged through testing the final outcome.
It covers all phases of stock from the starting elements, assumptions, and things to the education and personal hygiene of workers. Detailed, written plans are required for each method that could affect the nature of the finished product. There must be systems to produce documented proof that correct methods are consistently observed at each step in the production process, every time a commodity is made.
