Batch record review
Batch release waits on a page-by-page review that mostly confirms entries are fine. The agent checks every entry against the master record and your systems, and QA spends its time on the entries that need a decision.
Typical volumes for this process, not a client figure.
QA reads every page of every batch record before release, looking for gaps.
Every entry checked against the master record; QA reviews the flagged ones and decides.
Where the time goes today
An executed batch record can run to hundreds of pages: dispensing, line clearance, process steps, in-process results, labelling, reconciliation, printouts stapled in from equipment. Before a batch can be released, QA reads it all. Each entry needs a value, a unit, a signature and a date; critical steps need a second-person verification; values must sit within the limits of the master record; corrections must follow good documentation practice, with a single line, initials, date and reason.
Much of the review is cross-checking against other systems. Someone has to confirm that the balance on this line was within its calibration period on the day of use, that the material lots match what the warehouse dispensed, that the deviation referenced on page 42 is closed, and that the yield on the reconciliation page adds up. Each check means leaving the record and opening another system.
Most pages turn out to be correct, but nobody can know which ones without reading them. Review becomes the longest step between manufacture and release, and the attention it needs is spread evenly over entries that are almost always fine, which is when a blank field or a late correction slips through.
How the agent works
- Read the recordThe agent reads the scanned paper record or pulls the electronic one. Handwriting is read entry by entry with a confidence level; entries it cannot read with confidence are marked for a person, never guessed.
- Align to the masterIt maps each executed entry to its step in the master batch record, using the version that was effective on the date of manufacture.
- Check each entryIt checks completeness, signatures and second-person verifications, the sequence of dates and times, units, values against limits, and correction practice. It recomputes yields, reconciliations and any other calculation on the page.
- Cross-check systemsIt checks equipment identifiers against calibration and maintenance status on the day of use, material lots against dispensing records, and referenced deviations against their status in the quality system.
- Write the reviewIt produces an observation list, each with page, entry, expected value and value found, classified according to your review procedure, plus a status for every entry in the record.
What stays with a person
The release decision stays with the person your applicable GMP rules name for it; the agent never approves, signs or releases a batch. QA reviewers work through the observations and decide which are documentation errors to correct under your procedure and which are potential deviations to open. Corrections to the record itself are made by production, not by the software.
Reviewers also read every entry the agent marked as unreadable or low confidence. That list is short when scan quality is good and long when it is not, and it is the honest measure of how much reading the agent has taken off QA.
What it reads, what it produces
| It reads | It produces |
|---|---|
| The executed batch record, scanned or electronic | An observation list per batch, with page and entry references |
| The master batch record at the version effective on the manufacturing date | A status for every entry: checked, flagged or unreadable |
| Equipment calibration and maintenance records | Recomputed yields and reconciliations, shown next to the recorded ones |
| Dispensing and material lot data from the ERP or warehouse system | Confirmation of each referenced deviation's status |
| Deviations and change controls in the quality system | A trend of recurring documentation errors by step and by shift |
| Your review procedure and documentation practice rules |
Controls that come with it
- The agent never signs, approves or releases
- Every entry receives a status, so nothing is skipped silently
- Low-confidence handwriting always goes to a person
- Validated under your GMP rules for computerised systems, with a test set of past records rerun after every change
- A new master record version triggers a re-test before the agent reviews batches made under it
- A full audit trail: which entry was read, which rule applied, what was flagged
How you know it works
- QA review time per batch record
- Time from end of manufacture to release decision
- Observations found at final sign-off or audit that the agent missed
- Flagged entries dismissed by QA as not relevant
- Right-first-time documentation rate by process step
Is your process ready?
- Written rules: master records are written and versioned by nature, and your documentation practice rules exist. What is often missing is an agreed classification of observations; write it before the build.
- Systems: calibration, dispensing and deviation data must be readable by interface or export, and each vendor licence must permit automated reading.
- Cheap check: QA already signs off every batch, so each review the agent produces is checked by a qualified person as part of release.
- Volume: dozens of batches a month with long records repays the build and the validation. A few short records a month does not.
- One description: production and QA must agree what review by exception means for your site before the agent starts flagging.

What goes wrong
- Stamps, overlapping signatures and faint carbon copies degrade scans; fix the scanning before blaming the reading.
- Hybrid records with equipment printouts stapled in need each printout linked to its step, or values go unchecked.
- Reviewers who do not yet trust the checked status re-read everything, and no time is saved; plan a staged period with sampling.
- The validation effort is underestimated; agree the test set and acceptance criteria with quality before development starts.
Questions we get
Can the agent release a batch?
No. Release is a decision your applicable GMP rules assign to a named, qualified person, and it stays there. The agent prepares the review: every entry checked, every observation written up with its location, every calculation recomputed. The qualified person reads the observations, looks at anything unreadable, and decides. The agent has no permission to sign in your systems.
Does it work with paper records?
Yes, from scans, provided the scan quality is adequate. Handwriting is read entry by entry, each with a confidence level, and anything below your threshold goes to a person. Sites with good scanning practice get a short unreadable list; sites with poor scans get a long one, and the first improvement is usually at the scanner.
We have electronic batch records. Is there still a use?
Electronic records already enforce many entries, so the in-record checks matter less. The cross-checks remain: equipment calibration status, dispensing records, deviation status, and comparisons with other batches of the same product. For many sites with electronic records, those cross-system checks are where most of the review time now goes.
How is it validated?
Like any computerised system in a GMP environment: a documented intended use, a set of past batch records with known observations, acceptance criteria agreed with your quality unit, and change control. The same set is rerun after every change to the model, the rules or the master records, so any drift is visible before it reaches a live batch.
