How to Write Non-Conformance Report the Right Way

“From minor to major issues, every deviation tells a story. 

A non-conformance report captures that story with clarity, control, and compliance.”  

For quality and compliance leaders, audit readiness starts long before the regulator walks in. A non-conformance report (NCR) helps businesses capture, analyze, and resolve deviations from established processes, product standards, or regulatory requirements. As regulatory requirements grow more rigorous, poor NCR practices now top the list of audit observations across FDA, ISO, and global quality standards. 

Learning how to write a non-conformance report that is factual, traceable, and aligned with your organization’s risk posture can dramatically reduce the likelihood of repeat findings—and support successful inspections. Decision-makers need more than just a template. They need a systemized NCR process that transforms each deviation into a corrective strategy.   

This isn’t about compliance checklists. It’s about creating a high-integrity system for identifying failure, learning from it, and protecting future outcomes. This blog will explore how to write a non-conformance report in the right way, highlight key report elements, and guide organizations in streamlining their quality response through proven practices. 

Next, let’s break down why NCRs fail—and what makes well-written ones stand out in audits and reviews.  

The Importance of Writing a Non-conformance Report the Right Way 

A high-impact non‑conformance report drives corrective action—and protects your organization from repeat failures.  

Top-tier organizations treat the non‑conformance report process not as a formality, but as a critical input to governance and continuous quality improvement. ISO 9001, FDA QSR, and MHRA guidelines demand NCRs be factual, comprehensive, and traceable. Executives and quality teams depend on these reports to prioritize resources and close compliance gaps swiftly. 

When NCRs are poorly executed, the results can include: 

• Repetitive quality failures, as root causes remain unaddressed 

• Delays in CAPA—exposing operations to prolonged compliance risk 

• Audit citations from missing or inconsistent documentation 

• Damage to brand equity and degradation in stakeholder confidence 

On the other hand, well-crafted NCRs deliver: 

• Reliable audit trails and evidence for inspection readiness 

• Accelerated CAPA cycles, reducing business risk 

• Stronger interdepartmental collaboration through transparency 

Did you know? Recent FDA data shows that 30%+ of inspection observations stem from vague or incomplete non‑conformance report entries.  

Now that we’ve covered why writing an NCR the right way matters, let’s unpack how to classify deviations: minor vs major non‑conformance.  

Difference Between Minor and Major Non-Conformance Reports 

Not all deviations carry the same weight. Effective NCR systems distinguish between minor and major non-conformance reports, allowing organizations to focus investigative resources where the risk is greatest.   

Minor Non-Conformance: 

• Involves deviations with negligible impact on product quality or safety 

• Example: Using outdated forms without compromising process integrity 

• Often resolved quickly without escalated corrective action

Major Non-Conformance: 

• Involves failure to meet critical process, safety, or regulatory requirements 

• Example: Manufacturing a product without validated equipment 

• Typically triggers a full investigation and CAPA process

Criteria	Minor Non-Conformance	Major Non-Conformance
Impact	Low	High
Regulatory Risk	Minimal	Significant
Action Required	Immediate correction	Formal investigation + CAPA
Example	Missing signature	Product deviation affecting safety

 From the fact files? ISO 9001:2015 does not define “minor” or “major” non-conformances. These terms are contextual, based on each organization’s internal risk matrix.  

What is Included in a Non-Conformance Report 

A comprehensive non-conformance report includes more than just a problem description. It should be structured to support investigation, traceability, and future audits. Below are the essential components:  

1. Report ID/Reference Number – For tracking and documentation
2. Date of Detection – When the non-conformance was first observed 
3. Description of Non-Conformance – Objective, fact-based summary 
4. Affected Product/Process – Identifying what was impacted 
5. Root Cause Analysis – Tools like 5-Whys or Fishbone used 
6. Containment Action – Immediate measures taken 
7. Corrective/Preventive Actions (CAPA) – Long-term resolution 
8. Assigned Personnel – Owner of investigation and actions 
9. Verification & Closure – Confirming that CAPA was effective

With these fields in place, your NCR can act as a complete investigative and compliance document.

Nonconformance Report Process 

A structured non-conformance report process allows organizations to manage deviations with consistency. It ensures that each issue is documented, analyzed, and resolved in a traceable manner—supporting both compliance and continuous improvement.  

Here is a five-step framework widely implemented across compliant operations: 

1. Detection – Issue identified via routine monitoring, audits, or feedback 
2. Documentation – Initial data captured in a standardized report or digital QMS 
3. Investigation – Root cause analysis using structured tools 
4. Action Planning – Implementation of containment and corrective actions 
5. Closure Verification – Follow-up to confirm effectiveness before closure 

Up next, let’s explore how to write a crisp and audit-ready non-conformance report.  

Steps to write a Crisp and Clear Non-Conformance Report 

Knowing how to write a non-conformance report requires more than following a format. It involves clear communication, structured reasoning, and compliance-aware thinking. Executives and quality managers must ensure that their teams understand how to write a non-conformance report using a process-driven, compliance-first approach.  

Follow these reporting principles: 

1. Be Objective: Describe the event based on facts, not assumptions or blame. 
2. Sequence Events Logically: Present events in chronological order to support traceability. 
3. Use Quantifiable Data: Avoid generalizations; include measurable evidence. 
4. Attach Supporting Evidence: Inspection logs, photographs, or system logs should supplement the narrative. 
5. Apply Structured RCA Tools: Use 5-Whys or Fishbone for consistent analysis. 
6. Avoid Personal Attribution: Replace names with roles or process identifiers. 
7. Leverage Standard Templates: Maintain consistency using approved documentation formats. 

Let’s review NCR examples from different industries to contextualize these principles.  

Mini template sample for better understanding: 

• Title: Packaging Line Label Error 

• Date Detected: 03 July 2025 

• Non-Conformance Description: Product labels printed with outdated batch info 

• Root Cause: Operator used old template due to system lag 

• Immediate Action: Halted line and isolated affected boxes 

• Corrective Action: Updated label software and retrained staff

Examples of Nonconformance Report 

• Manufacturing Example: 

Title: Incorrect component used in assembly 

Root Cause: Wrong part pulled from bin due to mislabeling 

Action Taken: Updated bin labels; issued operator retraining  

• Pharmaceutical Example: 

Title: SOP deviation in batch documentation 

Root Cause: Operator skipped documentation step due to shift overlap 

Action Taken: Implemented checklist review system  

• Software Quality Example: 

Title: Missed validation test before release 

Root Cause: Test case was archived unintentionally 

Action Taken: Reviewed test management process; reinstated QA checkpoints  

These examples show how different industries can tailor NCRs while maintaining core principles.  

Common Mistakes to Avoid in NCRs

Even the most robust systems are vulnerable to breakdown when NCRs are poorly executed.  

Despite having structured procedures in place, many organizations fail to optimize the value of their non-conformance reports due to recurring process-level errors. Understanding how to write a non-conformance report includes knowing what to avoid as much as what to include.  

Here are five critical mistakes seen across industries: 

• Lack of specificity – Vague phrases like “defective output” offer no clarity for root cause analysis. 

• Missing root cause logic – Jumping to solutions without verifying the actual problem origin often leads to repeated issues. 

• No assigned ownership – Without designated accountability, NCRs remain unresolved or poorly followed up. 

• Overlooking closure verification – CAPA activities must be verified post-implementation to ensure effectiveness. 

• Timeline neglect – Delays in closing NCRs create compliance risks, especially during audits.
