Introduction to GMP

What Good Manufacturing Practice is, what it exists to prevent, and how its principles translate into the documents, systems and engineering decisions a facility is actually judged on.

  • EudraLex Vol. 4
  • 21 CFR Part 210
  • 21 CFR Part 211
  • WHO GMP
  • PIC/S PE 009
  • Schedule M

Every element of GMP can be traced back to a specific failure that killed or harmed people. Read that way, the rules stop being arbitrary and start being legible — which is the difference between a site that complies and a site that understands why it complies.

This module sets out what GMP is, the four risks every control ultimately addresses, how the documentation hierarchy carries them, and where the boundary between engineering practice and GMP qualification has to be drawn and defended.

What this module covers

Origins
The disasters that produced the rules — and why each major element of GMP can be traced to a specific failure.
Standards map
EudraLex Volume 4, 21 CFR 210 and 211, WHO TRS, PIC/S PE 009, Schedule M, and how they relate to each other.
What GMP is
The definition, and what the "c" in cGMP actually obliges a manufacturer to do.
Quality
Why quality cannot be tested into a product, and what that single idea implies for everything downstream.
The risks GMP controls
Mix-up, contamination, cross-contamination, and failure of traceability — the four things every control ultimately addresses.
The pillars of GMP
Premises, equipment, personnel, documentation, process and quality control, and how each is inspected.
Documentation hierarchy
From quality manual to record, what sits at each level, and the difference between an instruction and evidence.
GMP and GEP
Where engineering practice ends and GMP qualification begins, and why getting this wrong is expensive in both directions.
GMP and validation
How the validation lifecycle serves GMP rather than existing alongside it.
The regional landscape
EU, US, WHO, PIC/S and India compared — what is law, what is guidance, and what inspectors actually cite.

Questions this module answers

  • Can you state precisely what the "c" in cGMP obliges a manufacturer to do?
  • Which of your engineering activities are GMP-qualified, which are GEP-commissioned, and who decided?
  • Is your documentation set a hierarchy, or a collection of documents that grew separately?
  • Of the four risks GMP exists to control, which is your weakest control against?
  • For the markets you supply, which GMP text is law and which is guidance?
  • Could you defend your GEP/GMP boundary to an inspector tomorrow, from a written assessment?
