Batch Record Review Workflow

📋

Batch Record Review - The Complete, Contemporaneous Story of a Batch

The batch production record is the primary documentary evidence that a specific batch was manufactured according to its approved procedure, and its review is the final gate confirming that evidence is complete and coherent before the batch can be released. 21 CFR 211.188 requires batch production and control records for each batch, 211.192 requires investigation of any unexplained discrepancy, and 211.194 sets the standard for laboratory records supporting the batch. Together they expect a record built contemporaneously, step by step, rather than reconstructed from memory once production has already finished.

EU GMP Chapter 4

First-Person Review (Production)

Initial review performed by production personnel or supervisor confirming the record is complete and internally consistent immediately after execution.

Timing: Immediately post-execution

Second-Person Verification

Independent verification of critical steps performed contemporaneously by a second qualified individual during execution, not only at final review.

Timing: Contemporaneous with execution

Exception / Deviation Review

Focused review of any deviation, blank field, or discrepancy identified during the record, requiring documented investigation before proceeding.

Trigger: Any identified discrepancy

Final Quality Unit Review

Comprehensive final review by the quality unit, independent of production, forming the basis for the batch disposition decision.

Timing: Before batch release

Phase 1

Batch Record Preparation and Issuance

1Issue a controlled, numbered blank record

Blank batch record issued as a controlled document with a unique identifier, tracked from the master document control system.

21 CFR 211.188

↓

2Verify current approved master version

Issued record confirmed to match the currently approved master batch record revision, preventing use of an outdated or superseded version.

EU GMP Chapter 4

↓

3Reconcile against the document control log

Issued record logged and reconciled against the document control system, supporting complete traceability of every copy issued.

21 CFR 211.188

↓

4Assign batch number and cross-references

Unique batch number assigned and cross-referenced to relevant material lots and equipment identifiers before execution begins.

21 CFR 211.188

Phase 2

Real-Time Execution Documentation

5Document each step contemporaneously

Each step recorded at the time it is actually performed, never completed in a batch afterward or reconstructed from memory.

21 CFR 211.188

↓

6Record actual values, not checkmarks

Actual observed weights, temperatures, times, and other values recorded directly, rather than a simple checkmark implying compliance without evidence.

21 CFR 211.188

↓

7Apply the correction procedure for errors

Any documentation error corrected with a single line strike-through, initials, date, and reason, preserving the original entry's legibility.

EU GMP Chapter 4

↓

Are all critical steps documented with required second-person verification?

YES → Proceed to review NO → Complete missing verification

Phase 3

Review and Reconciliation

8Perform first-level supervisor review

Production supervisor reviews the record for completeness and internal consistency before it advances to quality unit review.

21 CFR 211.188

↓

9Reconcile yields and material usage

Actual material usage and product yield reconciled against theoretical values, with any variance outside expected range flagged for explanation.

21 CFR 211.103

↓

10Investigate discrepancies and blank fields

Any deviation, unexplained discrepancy, or blank field investigated and documented before the record proceeds toward final review.

21 CFR 211.192

Phase 4

Release Decision and Retention

11Perform final QA batch record review

Quality unit performs a comprehensive final review of the complete record, independent of the production function that executed the batch.

21 CFR 211.192

↓

12Make the batch disposition decision

Formal disposition decision made, releasing, rejecting, or placing the batch on hold pending further investigation, based on the complete reviewed record.

21 CFR 211.192

↓

13Retain the completed record per requirements

Completed batch record retained for the required retention period, remaining retrievable to support any future investigation or inspection.

21 CFR 211.180

Review Tier Requirements

Contemporaneous Second-Person Verification

Critical steps verified by a second qualified individual at the time the step is performed, not reconstructed during final review.

21 CFR 211.188

Independent Quality Unit Review

Final batch record review performed by personnel independent of the production function that executed the batch.

21 CFR 211.192

Documented Discrepancy Resolution

Every identified discrepancy formally investigated and documented before the batch disposition decision is made.

21 CFR 211.192

Missing or Incomplete Documentation Response Steps

Step 1 - Identify the specific gap Determine precisely which field, step, or verification is missing or incomplete in the record.

Step 2 - Determine whether contemporaneous completion is still possible Assess whether the missing information can still be legitimately obtained, or whether the window for contemporaneous documentation has passed.

Step 3 - Never backfill from memory as if contemporaneous Where the record cannot be completed contemporaneously, address the gap through a documented deviation rather than an undated retrospective entry.

Step 4 - Assess batch quality impact Evaluate whether the missing documentation raises a genuine question about the batch's quality or whether it is a documentation-only gap.

Step 5 - Document root cause and corrective action Investigate why the gap occurred and implement corrective action addressing the underlying documentation practice.

Data Integrity Requirements (ALCOA+)

Attributable and legible Every entry attributable to a specific, identifiable individual and legible enough to be read without ambiguity.

Contemporaneous and original Entries made at the time the activity occurred, preserved in their original form rather than transcribed or recreated later.

Accurate and complete Recorded values accurate to what actually occurred, with no field left blank without a documented explanation.

Consistent, enduring, and available Data consistent across related records, retained durably for the required period, and available for review or inspection when needed.

Batch Record Content Elements

Master vs Executed Record Distinction Clear distinction maintained between the approved master batch record template and the specific executed record for an individual batch.

Critical Step Sign-Off Explicit sign-off required at each critical step, distinct from routine step completion, reflecting the elevated verification that step demands.

Yield and Component Reconciliation Complete reconciliation of components used and product yield obtained, documented and compared against theoretical expectations.

Deviation Cross-Reference Any deviation occurring during the batch cross-referenced by number within the batch record, linking the two records together.

Equipment and Material Traceability Specific equipment identifiers and material lot numbers used documented, supporting full traceability for the batch.

Environmental Data Attachment Relevant environmental monitoring data for the batch's manufacturing period attached or referenced within the record where applicable.

Electronic vs Paper Record Controls Electronic batch records subject to the same data integrity expectations as paper, plus audit trail and electronic signature requirements.

Review Timeliness Standard Defined internal timeline for completing batch record review, preventing indefinite delay between batch completion and release decision.

Never do this

Complete batch record entries after the fact and represent them as contemporaneous. Allow the same person to both execute and independently verify a critical step. Release a batch with an unresolved discrepancy or unexplained blank field. Treat electronic batch records as exempt from the correction and traceability standards applied to paper.

Contemporaneous vs retrospective documentation

Contemporaneous documentation is recorded at the moment the activity happens, capturing what was actually observed. Retrospective documentation, reconstructed from memory after the fact, cannot provide the same evidentiary value and should never be presented as if it were contemporaneous.

First-person vs second-person review

First-person review is the individual confirming their own work is complete. Second-person verification is an independent check by someone else, providing a genuine control against individual error or oversight that self-review alone cannot provide.
