Good Manufacturing Practices

Good Manufacturing Practices, often written GMP or, in its enforceable US form, cGMP (current Good Manufacturing Practices), is a system of processes, procedures, and documentation that ensures products are consistently produced and controlled to defined quality standards. It governs the manufacture of pharmaceuticals, food, cosmetics, and medical devices, and its core promise is traceability: a regulator, an auditor, or a customer can follow the record from raw material to finished batch and see that quality was built in, not inspected after the fact.

• Documented procedures - Every step is written down, and work is done to the written procedure, so practice and record match.
• Batch traceability - Materials, equipment, and personnel are logged per batch, making any product recallable and any failure traceable.
• Validation and controls - Processes, equipment, and facilities are validated to prove they reliably yield the intended result.
• Audit readiness - The documentation trail is maintained so that a regulatory inspection can be satisfied at any time.

GMP is regulatory context rather than an API specification, but it shapes how APIs are built in regulated manufacturing. When a manufacturing execution or quality-management system exposes an API, the same expectations — immutable audit logs, validated changes, and traceable records — carry into the interface, and API governance becomes one more control that has to hold up to inspection. As manufacturers wire these systems to AI and agents, GMP’s demand for documented, verifiable process is exactly the discipline that keeps automated actions defensible.
