GMP, or good manufacturing practice, is a system manufacturers use to make sure all their products are the highest quality possible. Good manufacturing practice covers all areas of a manufacturing process, addressing things like:
- Equipment
- Cleanliness of workspace
- Raw materials
- Complaints
- Records

GMP has five core components, often referred to as the five Ps. Those five components represent the areas of your business that it is necessary to optimize by applying good manufacturing practice. The goal of GMP is that your products end up consistent, appropriate for their intended use, and high quality.
Among the benefits of this quality management system are:
- Reduced waste
- Increased productivity
- More profits
- Fewer recalls or other production issues
