"Good manufacturing practice" or "GMP" is part of a quality system covering the manufacture and testing of active pharmaceutical ingredients, diagnostics, foods, pharmaceutical products, and medical devices. these guidelines provide minimum requirements that a pharmaceutical or a food product manufacturer must meet to assure that the products are of high quality and do not pose any risk to the consumer or public.GMP covers all aspects of production from the starting materials, premises and equipment to the training and personal hygiene of staff. Detailed, written procedures are essential for each process that could affect the quality of the finished product. There must be systems to provide documented proof that correct procedures are consistently followed at each step in the manufacturing process - every time a product is made Good manufacturing practices (GMP) are the practices required in order to conform to the guidelines recommended by agencies that control authorization and licensing for manufacture and sale of food, drug products, and active pharmaceutical products.

GMPs are guidelines that outline the aspects of production and testing that can impact the quality of a product. many countries have legislated that pharmaceutical and medical device companies must follow GMP procedures,and have created their own GMP guidelines that correspond with their legislation.

Benefits provided by GMP:

• It establishes the first step of HACCP Food Safety System as it arranges the infrastructure and work environment of the product to be manufactured.
• It ensures positive results from official audits (Production Permit, Work Permit and Food Registry) as it covers all minimum requirements necessary to gain official permissions.
