First of all, GMP is the abbreviation of good manufacturing practices, which has become a "good production practice" in the industry and a requirement for the quality system of production enterprises. According to these requirements, the products can be guaranteed to meet the expected requirements. These requirements start from the source of production (raw and auxiliary materials) and cover the production process, environmental control, personnel control and after-sales complaints and recalls. The specification requires that production enterprises can trace the production batch records according to customer complaints, and trace the production personnel and the production situation at that time from the batch records, so as to judge whether there are quality problems in the production process and whether there are problems in the transportation process.

Because the implementation of this quality management system requires a lot of manpower and material resources, there is no mandatory requirement for general enterprises. Only drugs produced in China are enforced according to GMP. GMP in China was promulgated by the US Food and Drug Administration and is currently being revised in 1998, which can be found on the website of the Food and Drug Administration. However, the new version of GMP will be promulgated soon, which will make the domestic requirements equal to those of developed countries such as the European Union, and will also greatly improve the entry threshold for pharmaceutical manufacturers.

GMP training is the training of this management concept. The idea of GMP is that quality is produced, not tested. It means that when the last working procedure of the product is completed, the quality of the product has been formed, and this quality will not change with the changes of inspection instruments and inspectors. No matter how good your testing instrument is, you can only find defects and can't correct them. Even because general sampling is sampling, there is a probability problem. Passing the inspection can only show that all the samples you take are qualified, and there is no guarantee that all the products are qualified. In order to obtain a good product, the most important thing is to strictly control every process of production. To be extreme, if the production process is designed reasonably and implemented effectively, the final inspection will become waste.
