In pharmaceutical manufacturing, the batch record (BR) review is more than a regulatory formality — it’s a critical control point for ensuring product quality and release readiness. For many organizations, this step remains a manual, paper-heavy, and time-consuming exercise. Years of process and checks are layered on the documents, generating complex layouts and many handwritten notes. Review cycles stretch for days or even weeks, tying up valuable inventory and staff time.
Yet the data in batch record documents holds the key to product quality, patient safety, reduced deviations and yield optimisation. Beyond GMP and regulatory requirements, efficient batch reviews are a driver of profitability and performance for the whole organisation. Especially for CDMOs whose batch records are heavily scrutinised by their clients.
The Electronic Batch Record (EBR) Dilemma: while fully integrated Manufacturing Execution Systems (MES) and EBR platforms are appealing, the costs and complexity of implementation—often running into millions—plus the physical limitations of existing equipment make them a distant goal for many manufacturers.
How can paper batch record processes be improved without spending millions? Where can digital and automation tools provide support without requiring complex rewiring and transformation?
Who This Guide Is For:
- Quality Assurance Managers seeking to reduce review backlogs and improve RFT

Stage 1: Manufacturing Floor — Getting It Right the First Time
The most efficient review is one focused on critical quality decisions, not hunting for missing signatures. The foundation of improvement starts where the data is generated: on the manufacturing floor.
1. Track Top 5 KPIs and Implement "Right First Time" (RFT) Incentives ⭐⭐
The Challenge: You cannot improve what you don't measure. Without visibility into error patterns, teams default to a "QA will catch it" mindset rather than owning data quality.
Action: Identify and track the 5 most impactful indicators for your context. Common choices include:
- Right First Time (RFT) rate per batch
- Number of missing signatures per batch
- Number of minor deviations
- Calculation errors requiring correction
- Average time to resolve investigations
Display these metrics publicly in manufacturing areas. Recognize teams with the lowest error rates through symbolic awards, certificates, small bonuses, or other meaningful recognition.
✅ Why It Works: Pride and drive for progress are powerful motivators. Public KPIs create healthy competition and enable proactive feedback loops. One mid-sized CDMO reported a 35% improvement in RFT rates within three months of implementing visual KPI boards and monthly recognition.
2. Adopt Concurrent Review: Don't Wait Until the Batch Is Finished ⭐⭐
The Challenge: Traditional batch record reviews happen after the entire manufacturing process is complete—often days or weeks after the events occurred. By then, operators may have moved to different batches or shifts, and memories have faded.
Action: Assign a supervisor or designated "in-process reviewer" to check paperwork at the end of every shift or after each unit operation completes. For example, immediately after granulation is finished, review that section before the team disperses.
✅ Why It Works: Errors are caught while the crew is still present and events are fresh in memory. Corrections become instantaneous conversations rather than investigations requiring people to reconstruct what happened weeks ago. This approach can reduce deviation investigations time by 40-50%.
3. Improve "Visual Management" in Templates ⭐
The Challenge: Complex batch record templates create cognitive overload. Operators struggle to know which fields are mandatory, which are conditional, and where to focus attention.
Action: Redesign the physical paper record to be nearly impossible to complete incorrectly:
- Use shading (grey out boxes that don't require input)
- Apply distinct borders or colors for Critical Process Parameters (CPPs) and Critical Quality Attributes (CQAs)
- Include explicit "N/A" checkboxes for fields that may not apply
- Pre-print units of measure (e.g., "_____ kg" instead of leaving it blank)
✅ Why It Works: Reviewers can scan pages visually. An empty white box signals an error; an empty shaded box is acceptable. This reduces cognitive load for both operators completing the record and reviewers checking it. Visual design leverages human pattern recognition—our brains spot deviations from expected patterns in milliseconds.
4. Implement a "Buddy Check" System for Calculations ⭐
The Challenge: Math errors are the easiest to make, especially in night shifts, and hardest to correct retroactively because they often imply the wrong amount of material was added.
Action: Require a second operator to verify and initial all calculations. This includes yield calculations, dilution ratios, equipment settings based on batch size, and material quantity verifications.
✅ Why It Works: No one gets it always right and it’s hard to catch your own mistakes. Just bake it in the process.
Stage 2: Early Detection — Catching Errors Early to Enable Fast Resolution
Even with strong floor practices, some errors will slip through. The key is detecting them immediately rather than discovering them days later during formal QA review.
5. Implement Automated Checks Before Sending to QA ⭐⭐⭐
The Challenge: Batch records often sit on a QA reviewer's desk or email inbox for days. When errors are discovered, the resulting back-and-forth between QA and Operations adds days to the review cycle.
Action: Before submitting batch records to QA, scan the completed documents and run them through an automated verification solution. These systems can check for:
- Missing entries and signatures
- Batch number consistency across all pages
- Date sequence and logic
- Calculation correctness
- Out-of-specification or out-of-range values
- Completeness of required attachments
Solutions like Acodis Batch Record Review, as well as a few other specialised document automation platforms, can perform hundreds of such checks in minutes.
✅ Why It Works: A quick correction or additional piece of information provided immediately can eliminate entire rounds of back-and-forth between teams and save days of review.
6. Establish a Rapid Deviation Resolution Workflow ⭐⭐
The Challenge: Deviations discovered days after occurrence require time-consuming investigations to reconstruct events, gather statements, and determine root cause.
Action: As soon as a deviation occurs or is spotted, the Supervisor must immediately classify it:
- Minor: Simple documentation errors, minor variance within acceptable limits: documented and closed before the shift ends
- Major: Out-of-specification results, equipment failures, unplanned material substitutions: a parallel process involving QA immediately
✅ Why It Works: This triage system prevents low-risk issues from clogging the formal deviation process while ensuring serious problems get immediate attention. It also captures information while fresh.
7. Use Coloured Flags or Digital Bookmarks ⭐
The Challenge: Batch records for complex products can exceed 150 pages. Reviewers waste significant time flipping through documents searching for specific sections, attachments or issues.
Action: As the batch record is assembled, use color-coded or digital bookmarks:
- Physical records: Use coloured sticky tabs or digital bookmarks (Red for deviations, Yellow for critical calculations, Green for Certificate of Analysis attachments, Blue for Material Reconciliation)
- Digital scans: Apply bookmarks in PDF viewers or specialized software such as the Acodis Batch Record Review that allow jumping directly to flagged sections
✅ Why It Works: Reviewers can jump immediately to high-risk areas without hunting through hundreds of pages. This simple organizational tool can save 30-60 minutes per batch review.
Stage 3: QA Review Efficiency — Automation & Systematic Processes
The QA review includes many repetitive checks and documentation steps. Streamlining these through automation and structured approaches allows QA professionals to focus on true quality decisions.
8. Create Reviewer Checklists ⭐
The Challenge: Reviewers often rely on memory and experience to navigate complex batch records, leading to inconsistency between reviewers and lost time when switching products.
Action: Create a product-specific or batch-record-specific checklist that serves as a roadmap for the reviewer. Include:
- Specific page numbers where CPPs and CQAs are documented
- Required attachments with expected page counts
- Known complexity areas requiring extra scrutiny
- Sequence of review (risk-based rather than page-by-page)
Provide this as a cover sheet that the reviewer completes and signs as evidence of systematic review.
✅ Why It Works: Checklists ensure the reviewer prioritizes safety and efficacy data first rather than getting bogged down in administrative formatting issues. They also provide training tools for new reviewers and create consistency across the team. Studies in other high-reliability industries show checklists reduce oversight errors by 30-50%.
9. Use Automated Checks and Summaries to Decrease Load on QA ⭐⭐⭐
The Challenge: QA reviewers often spend hours performing repetitive verification tasks and checks on the batch documents.
Action: Upload scanned batch records to a dedicated automation tool that can:
- Automatically verify hundreds of data points and completeness checks
- Flag discrepancies or missing information for human review
- Generate draft review summaries highlighting key data and any issues
- Extract data for Bill of Materials consumed
- Pre-populate deviation forms with relevant batch information
Different solutions exist in this space, including Acodis Batch Record Review among a few Life Science Quality specialists.
✅ Why It Works: Computer-based checks not only save review time (typically 40-60% reduction) but also catch more errors through consistent application of rules. These systems also support online collaboration, full traceability of review decisions, and faster downstream actions like Product Quality Review (PQR) data gathering, deviation analysis or yield improvement initiatives.
10. Establish Dedicated "Correction Hours" ⭐
The Challenge: Batch records often sit on desks in "waiting for information" status, particularly when specific operators are on days off or busy with current production and unavailable to address questions about previous batches.
Action: Establish a specific daily time window (e.g., 2:00 PM - 3:00 PM) where operators and supervisors are specifically available to address documentation corrections and questions from QA.
Schedule this during a lower-intensity period in the production day. Make this a protected time—operators should not be pulled into production emergencies except in genuine crises.
✅ Why It Works: Both QA and Operations know when to expect availability, reducing frustration and accelerating resolution. This simple scheduling change can eliminate days of "wait time" per batch and contributes to a more collaborative work atmosphere.
Stage 4: Collaboration: Efficient Processes Are Achieved when People Work Well Together
Technology and procedures alone won't transform your batch record review process. Lasting improvement requires changing how QA and Operations teams view their roles and each other.
11. "Coach & Empower" Mindset ⭐⭐
The Challenge: Traditional quality cultures, regulatory demands and time pressure can lead to adversarial relationships. Operations perceives QA as nitpicky gatekeepers; QA views Operations as careless. When QA corrects errors on behalf of operators "just to move things along," it teaches reliance on the QA safety net, leading to repeat errors and stagnating RFT metrics.
Action: Transform the QA-Operations relationship from enforcement to coaching:
- Avoid blaming language. Instead of "You made another mistake," try "I noticed this field was left blank—let's talk about why this data point matters to the patient."
- Treat errors as learning opportunities. Focus on why it matters and how to do it better next time.
- Never correct on behalf of others just to save time. Require the person who made the error to correct it themselves (with coaching if needed).
- Make expectations clear with dignity. "I know you want to do excellent work. Here's what 'excellent' looks like for this process..."
✅ Why It Works: Most people genuinely want to do well and will improve when treated with respect and given proper context. Research in organizational psychology consistently shows that blame cultures suppress reporting and learning, while growth-mindset cultures accelerate improvement.
12. Create Shared Batch Record Review Certification ⭐⭐⭐
The Challenge: Friction and misunderstanding occur because QA demands are perceived as overly burdensome by Operations, while Operations errors are perceived as carelessness by QA. This results from a lack of shared perspective on the batch record's function and consequences.
Action: Mandate shared, cross-functional Batch Record Review Certification:
For QA reviewers:
- Spend a shift shadowing or executing operational steps to understand data entry challenges
- Experience the difficulty of recording data, managing time pressure or working with inconvenient equipment placement
- Understand why certain errors happen
For Operations Supervisors:
- Perform a simulated QA review of a historical batch record (ideally one with errors)
- Review actual FDA 483 observations or warning letters related to batch record deficiencies
- Understand the direct regulatory consequences and patient safety implications of their documentation
✅ Why It Works: Beyond training skills and mutual understanding, such programs build empathy and respect. When QA reviewers understand why an operator might skip a signature during a crisis, they can design better processes. When operators see how incomplete documentation can halt drug distribution to patients who need it, they related to the impact.
Stage 5: Continuous Improvement — Optimizing Your Master Batch Record
With KPI tracking and strong collaboration, it becomes easier to spot the patterns and distinguish the issues that are execution related from those resulting from the process design. Improving the overall process and the Master Batch Record can further support efficiency and happiness at work.
13. Limit Free Text Entries and Create Handwriting Guidelines ⭐⭐
The Challenge: Illegible handwriting is a massive time sink during review and prevents Optical Character Recognition (OCR)-based automation. Free-text comments introduce ambiguity and variability.
Action: Systematically reduce handwriting requirements:
- Replace comments with pre-set choices: Instead of writing "Scale calibrated ok," provide a checkbox: "☐ Scale Calibrated"
- Pre-print constants: If a unit of measure is always the same, pre-print it ("_____ kg")
- Require CAPITAL LETTERS for key fields and important notes
- Create a one-page "Documentation Standards" poster showing acceptable versus unacceptable examples of handwriting, date formats, and abbreviations. Make it fun so it remains engaging.
✅ Why It Works: Structured data eliminates ambiguity and the need for reviewers to decipher handwriting or guess missing units. It also enables future OCR automation as you digitize your processes.
14. Remove Unnecessary Fields — The "So What?" Filter ⭐⭐
The Challenge: Over time, organizations layer on requirements and checks, many of which become redundant or superfluous. Every data field costs time to complete, review, and manage - yet not all fields add value.
Action: Conduct a systematic review of your Master Batch Records. For every signature, checkbox, or data field, ask: "If this specific data point were missing or wrong, would it violate a specific GMP regulation or affect the safety or efficacy of the drug? If the answer is "no", consider removing it.
✅ Why It Works: Elimination of unnecessary documentation allows focus to remain on what actually matters rather than mindless tick-boxing.
15. Redesign Complex Logics — The "Friction" Filter ⭐⭐⭐
The Challenge: Some sections of batch records generate errors not because operators are careless, but because the template design itself creates friction and opportunities for mistakes.
Action: Conduct "gemba walks" — spend time on the floor observing operators physically filling out problematic sections. Watch for:
- Math performed on calculators: Consider pre-calculating or providing reference tables
- Flipping pages back and forth: Bring reference information forward or consolidate related data
- Squeezing handwriting into tiny rows: Increase spacing or split into multiple lines
- Confusion about which row to use: Improve labelling or visual design
- Looking up the same information repeatedly: Pre-print or provide at point of use
✅ Why It Works: Templates are often complex for legitimate reasons—but you cannot identify how to fix them by sitting at a desk applying standard frameworks.
