What is GMP (Good Manufacturing Practice)?
GMP, or Good Manufacturing Practice, is an international guideline for the quality and safety of production processes. The aim of GMP is to ensure that products — particularly in pharmaceuticals, food, cosmetics and medical devices — are consistently produced and controlled in accordance with established quality standards.
GMP = prevention rather than correction.
🎯 Why is GMP important?
| Goal | Description |
|---|---|
| Consistent product quality | Every product must meet specifications, batch after batch |
| Consumer safety | No contamination, errors or unknown variation in production |
| Traceability | Every process, ingredient and change must be traceable |
| Compliance with legislation | Compliance with regulations such as EU-GMP, FDA, WHO GMP |
| Audits & inspections | Production must be fully verifiable for regulators |
🔧 What does GMP regulate specifically?
GMP includes requirements on, among other things:
- Personnel – training, hygiene, accountability
- Premises & equipment – clean, suitable and controlled
- Documentation – everything must be recorded and traceable
- Raw materials – validated, registered and controlled
- Production processes – validated and assured (e.g. with MES or LIMS)
- Quality control – samples, testing and release criteria
- Complaints and recalls – procedures for handling and reporting
🏭 Examples of GMP applications
| Sector | Example process under GMP |
|---|---|
| Pharmaceuticals | Filling and packaging injectable solutions |
| Food | Mixing and filling of dairy or infant formula |
| Cosmetics | Batch production of creams, lotions or shampoos |
| Medical devices | Assembly and sterilisation of surgical instruments |
🔗 GMP and automation (OT)
| System | GMP role |
|---|---|
| MES | Securing batch records, recipe management and electronic signatures |
| LIMS | Recording analysis results, batch release and data integrity |
| SCADA | Process monitoring and alarm history for GMP reporting |
| Historian | Continuous logging of process data (temperature, pressure, flow) |
🔐 Data Integrity & GMP
Part of GMP is safeguarding data integrity, in line with the ALCOA+ principles:
- Attributable – traceable to the source/user
- Legible – readable and permanent
- Contemporaneous – recorded at the moment of action
- Original – original data (or true copy)
- Accurate – correct and complete
- Consistent, Enduring, Available
📌 In summary
GMP is a global quality framework that compels production companies to operate with care, documentation and control. Automation with MES, LIMS and SCADA supports compliance with GMP guidelines.
