In GMP manufacturing, the batch record is the evidence. It is the contemporaneous, signed account of exactly how a batch was made and tested — and in an inspection, it is the first thing a reviewer reaches for. Getting batch records right is not paperwork for its own sake; it is what makes your quality real and defensible.
What a batch record captures
- Materials: identities, lots and quantities of every input.
- Process steps: each operation, parameter and in-process control, recorded as performed.
- Equipment: what was used, and that it was qualified and clean.
- People: who performed and who verified each critical step.
- Results & deviations: testing results, any deviations and their resolution.
- Disposition: the quality decision to release or reject.
ALCOA+ in practice
Audit-ready records embody the ALCOA+ data-integrity principles: Attributable, Legible, Contemporaneous, Original, Accurate — plus Complete, Consistent, Enduring and Available. In short, the record must show who did what, when, with what, and that nothing was reconstructed after the fact. This is the operational heart of data integrity and digital R&D.
Key point: “audit-ready” means ready now, not reconstructed later. Records assembled after the fact are the single most damaging finding in an inspection.
Common findings to avoid
- Entries completed late or in advance rather than contemporaneously.
- Missing signatures, verifications or dates.
- Unexplained deviations or uninvestigated out-of-specification results.
- Illegible or corrected entries without proper audit trail.
Why it protects your program
Strong batch records turn an inspection from a threat into a formality, and they are the raw material for your CMC filing. They are exactly what to probe when evaluating a manufacturer — see how to choose a peptide CDMO — and a hallmark of a mature quality system built around ICH Q7.
