Introduction

With the February 2, 2026 deadline approaching, companies are rushing to implement QMSR requirements. Speed creates risk. Based on transition assessments of dozens of medical device manufacturers, we're observing patterns of mistakes that present significant compliance risk and are likely to draw FDA scrutiny during post-2026 inspections—or worse, will require expensive rework after the deadline.

This article identifies the most common compliance gaps we're seeing and provides practical guidance on avoiding them. The regulatory requirements are clear enough to act on today; waiting for additional FDA guidance consumes the remaining transition time without progress.

Key regulatory references:

• Final Rule: 21 CFR Part 820 (QMSR), effective February 2, 2026 (Federal Register, Vol. 89, No. 23, February 2, 2024)
• Incorporated by reference: ISO 13485:2016
• FDA-specific additions: 21 CFR §820.35 (Control of Records), §820.45 (Device Labeling and Packaging Controls)
• FDA resources: QMSR Key Takeaways (FDA website), QMSR Premarket Draft Guidance (November 2025)

Strategic Mistakes

Mistake 1: Treating QMSR as a Documentation Exercise

The mistake: Focusing on updating document titles, updating the Device Master Record (DMR) to Medical Device File (MDF) structural format, revising regulatory references in procedures—while ignoring operational changes that actually matter.

Why it happens: Documentation changes are visible and feel productive. Operational changes require harder conversations about how work actually gets done.

The problem: FDA will not cite you for the terminology you use to describe your device master records. However, FDA will cite you for quality system gaps, including:

• Combined corrective/preventive action procedures that don't adequately separate reactive from proactive processes
• Management review records that lack required inputs and evidence
• Risk management that exists on paper but doesn't influence actual decisions
• Supplier oversight procedures that don't reflect operational reality

Critical distinction: The DMR-to-MDF transition is not simply a rename. ISO 13485:2016 defines the Medical Device File (MDF) as a consolidated structure that integrates design history, master record, and production/quality documentation (ISO 13485:2016, Clause 4.2.3). This represents a structural and organizational shift, not cosmetic relabeling. The content scope and integration requirements differ materially from QSR-era DMR practices.

How to avoid it:

• Prioritize operational gaps over documentation cosmetic changes
• Focus gap analysis on process compliance, not document terminology
• Ask "what do we actually need to change about how we work?" not "what do we need to rename?"
• Map operational changes directly to ISO 13485:2016 clauses and corresponding procedures
• Verify that personnel understand the substantive "why" behind procedure changes

---

Mistake 2: Assuming ISO 13485 Certification Equals QMSR Compliance

The mistake: Companies with ISO 13485:2016 certification assume they are automatically QMSR-compliant and do minimal transition work.

Why it happens: QMSR incorporates ISO 13485:2016 by reference. Same standard, same compliance—or so it seems.

The problem: FDA explicitly states that ISO 13485 conformance certifications do not exempt firms from FDA inspections and do not demonstrate QMSR compliance. Specific gaps include:

• FDA-specific additions (21 CFR §820.35, §820.45) address records control and labeling/packaging oversight beyond ISO scope
• UDI requirements (21 CFR Part 830) and device identifier controls are FDA additions not covered by ISO certification
• Inspection methodology differs: Certification auditors use sampling-based audits; FDA investigators apply risk-based, data-driven inspection approaches with different intensity
• Records that passed certification sampling may not withstand FDA inspection scrutiny under different sampling intensity and investigation protocols
• FDA may interpret requirements differently than certification auditors even on identical clauses
• Certification is point-in-time; compliance drift can occur between audit cycles

Regulatory reference: FDA Preamble to QMSR final rule explicitly addresses this distinction. FDA does not recognize ISO 13485 certification as exempting firms from U.S. regulatory requirements.

How to avoid it:

• Assess your QMS against FDA-specific additions explicitly (Parts 803, 806, 821, 830 in addition to Part 820)
• Review records and processes with FDA inspection intensity in mind, not certification sampling criteria
• Verify that your management review process addresses all ISO 13485:2016 Clause 5.6 inputs (not just those required by certification)
• Don't assume certification means inspection readiness
• If ISO-certified, conduct a specific gap assessment against QMSR requirements, treating them as separate compliance obligations

---

Mistake 3: Waiting for FDA Guidance

The mistake: Delaying implementation waiting for FDA to publish comprehensive implementation guidance, QMSR inspection procedures, or additional clarification.

Why it happens: Companies want certainty before investing resources. "What if we implement something and FDA clarifies it differently?"

FDA's actual guidance posture: As of December 2025, FDA has:

• Released the final rule with preamble (February 2024)
• Published "QMSR: Key Takeaways" document
• Issued draft guidance on QMS information for certain premarket submissions (November 2025)
• Hosted QMSR webinars (December 2025)
• Explicitly stated it does not intend to issue comprehensive implementation guidance before the February 2026 effective date

The requirements are in ISO 13485:2016 and the final rule preamble. They are clear enough to act on.

The problem: The deadline doesn't move. FDA provided two years of implementation time (doubled from the initially proposed one-year transition in response to industry comments). Waiting for additional guidance consumes that time without progress.

How to avoid it:

• Implement based on reasonable interpretations of ISO 13485:2016 and the final rule
• Reference the ISO 13485:2016 standard and QMSR preamble language when making implementation decisions
• Document your interpretation basis for requirements where ambiguity exists
• Adjust if FDA provides different guidance later—that is easier than starting from zero on February 3, 2026
• Use gap analysis templates aligned to ISO 13485 clauses to drive implementation, not wait for FDA procedures

---

Mistake 4: Under-Resourcing the Transition

The mistake: Treating QMSR transition as a side project for the quality team to handle alongside normal responsibilities.

Why it happens: Companies underestimate the scope of operational changes required, especially for:

• U.S.-only companies new to ISO 13485 framework
• Organizations without MDSAP experience
• Companies with mature QSR systems that must fundamentally shift operational philosophy

The problem: Quality teams are already fully loaded. Adding major transition work without additional capacity means something won't get done—either normal quality work or transition work. Both suffer, and corrective action systems become backlogged.

Specific scope underestimation: QMSR transitions typically require:

• Risk management integration throughout lifecycle (ISO 13485:2016 Clauses 4–8), not just design phase
• CAPA process redesign for CA/PA separation with distinct triggers and workflows
• Management review redesign with comprehensive inputs and inspectable records
• QMS software validation documentation for document control, training, CAPA databases, complaints systems
• Customer communication and feedback procedure development
• Supplier risk assessment and monitoring procedures aligned to risk-based approach
• Internal audit competency development for ISO 13485 assessment
• Training program updates and competency verification

How to avoid it:

• Assess transition scope realistically across all ISO 13485:2016 requirements (not just high-profile changes)
• Allocate dedicated resources—internal subject-matter experts OR external consulting support OR both
• Secure executive commitment for resource allocation with visible sponsorship
• Reduce other quality team obligations during the critical transition window (next 45–60 days) if needed
• Establish project governance with clear accountability, milestones, and tracking

Documentation Mistakes

Mistake 5: Creating Separate CA and PA Procedures Without Substance

The mistake: Splitting your CAPA procedure into two documents but keeping essentially the same process for both. You now have two procedures that describe the same thing.

Why it happens: Companies recognize that QMSR requires CA/PA separation but don't understand the substantive difference between corrective and preventive action. They rename processes without redesigning them.

The regulatory requirement: ISO 13485:2016 specifies:

• Clause 8.5.2 – Corrective Action: Addressing nonconformities (existing problems)
• Clause 8.5.3 – Preventive Action: Addressing potential nonconformities (prevention of problems)

These are separate requirements because they have fundamentally different triggers, approaches, and success metrics. Combining them into a single CAPA process was acceptable under QSR but violates the ISO 13485 structure.

The problem: Having two documents doesn't demonstrate separate processes. If your "preventive actions" all start from actual problems (complaints, deviations, failures), you've renamed corrective actions, not created preventive actions. FDA investigators will immediately recognize this gap. During inspection, investigators will review:

• Whether PA triggers are truly prospective (based on trends, risk assessments, near-misses, industry alerts)
• Whether CA triggers are reactive (based on actual nonconformities)
• Whether metrics distinguish between CA and PA activities
• Whether closure criteria differ between processes

How to avoid it:

Understand the fundamental distinction:

• Corrective Action (ISO 8.5.2): Addressing existing nonconformities (reactive)
• Preventive Action (ISO 8.5.3): Addressing potential nonconformities (proactive)

Define distinctly different triggers for each process:

Corrective Action Triggers	Preventive Action Triggers
Customer complaints	Trend analysis (e.g., yield declining 2% quarter-over-quarter)
Audit findings	Risk assessment identifying potential vulnerabilities
Internal nonconformances	Near-miss events (close calls that didn't result in failure)
Process deviations	Industry alerts or regulatory updates
Product failures	Process observations suggesting capability concerns
Customer feedback indicating problems	Supplier performance data showing emerging risks
Deviation reports	Change impact assessments

Implement operational separation:

• Define separate procedures with explicit triggers for each
• Use different templates, forms, or workflow categories to ensure operational visibility
• Track metrics separately (number of CAs initiated vs. PAs initiated; closure rates; effectiveness; cost impact)
• Ensure personnel understand the difference in their roles (who initiates, who investigates, who approves)
• Document decisions that changed because of PA assessment (e.g., "Risk assessment identified potential for operator error in step 3; preventive action implemented enhanced training prior to failure occurrence")

Measure success:

• Both processes are active in the QMS with documented evidence
• PA metrics demonstrate proactive activity (not just CA activity)
• Closure documentation shows different approaches, root causes, and actions

---

Mistake 6: Ignoring Management Review Record Quality

The mistake: Continuing to conduct management review the same way you always have, with informal notes, incomplete input coverage, or weak follow-up documentation.

Why it happens: Management review was exempt from FDA inspection under QSR 21 CFR §820.180(c). Nobody was looking, so documentation quality didn't matter.

The regulatory change: QMSR removed the 21 CFR §820.180(c) exemption. Management review records are now fully inspectable by FDA investigators, with the same rigor applied to other quality records.

The problem: Informal or incomplete records will draw scrutiny and potentially result in findings. FDA investigators expect:

• Comprehensive agenda addressing all ISO 13485:2016 Clause 5.6 required inputs
• Evidence of discussion (not just attendance)
• Documented decisions with clear rationale and decision-maker accountability
• Action items assigned with specific owners and due dates
• Follow-up tracking demonstrating closure and evidence of implementation

Management review must address ISO 13485:2016 Clause 5.6 inputs:

• Status of actions from previous management review
• Feedback from external parties (customers, regulators, notified bodies)
• Process performance and product conformity data
• Effectiveness of risk management activities
• Effectiveness of corrective and preventive actions
• Follow-up from internal audits
• Adequacy of resources
• Organizational changes affecting QMS
• Opportunities for improvement

How to avoid it:

• Create a comprehensive, mandatory management review agenda addressing all Clause 5.6 inputs
• Establish clear format and documentation requirements (e.g., meeting minutes template)
• Document actual discussion, not just attendance list (e.g., "Quality Manager presented complaint trend showing 15% increase in sterility concerns from Supplier A; team discussed root cause assessment in progress; decision: escalate to supplier audit before next production run")
• Record decisions with rationale (e.g., "Decided to invest in upgraded environmental monitoring equipment: ROI on reduced recalls estimated at $400K annually; implementation by Q2 2026")
• Assign action items with specific owners, due dates, and acceptance criteria
• Track actions to closure with evidence (completed training records, audit reports, lab confirmations)
• Ensure management review demonstrates strategic QMS oversight, not just operational metrics review

---

Mistake 7: Leaving Internal Audit Findings Open

The mistake: Having internal audit findings from months or years ago that remain open without documented corrective action or closure.

Why it happens: Internal audits were exempt from FDA inspection under QSR. Open findings were internal matters without regulatory consequence.

The regulatory change: Internal audit records are now fully inspectable under QMSR. Open findings are no longer an internal matter.

The problem: Open findings suggest your corrective action process doesn't work. If you can't close findings from your own internal audits, how will you address external findings (customer complaints, FDA observations)? This signals ineffective CAPA process to any investigator.

FDA inspection perspective: Investigators review:

• How long findings remain open
• Whether corrective actions are actually implemented
• Whether closure is supported by evidence
• Whether effectiveness checks verify corrective action worked

How to avoid it:

• Review all open audit findings with target closure dates
• Close findings with documented corrective action and evidence of effectiveness
• If closure isn't possible, formally document justification (e.g., "Finding regarding supplier process capability remains open pending 2026 supplier audit; interim controls established; re-evaluation date Q2 2026")
• Escalate findings that cannot be closed to management for formal acceptance of risk or alternative control
• Establish and enforce reasonable closure timeframes (e.g., minor findings 30 days, major findings 60 days, critical findings 15 days)
• Implement automated tracking to surface overdue findings to quality leadership monthly
• Use overdue findings as a management review input (Clause 5.6)

---

Mistake 8: Missing QMS Software Validation Documentation

The mistake: Using document control systems, training management software, CAPA databases, complaint systems, or other QMS software without adequate validation documentation.

Why it happens: QSR requirements for QMS software validation were implicit. Many systems were implemented without formal validation or with minimal documentation. Companies assumed "if it works, it's fine."

The regulatory requirement: 21 CFR §820.35 and ISO 13485:2016 Clause 4.1.6 explicitly require validation of computer software used in QMS functions:

• 21 CFR §820.35: "Where a manufacturer uses computer software in the manufacturing or quality system, the manufacturer shall validate the computer software for its intended use."
• ISO 13485:2016 Clause 4.1.6: "When monitoring and measuring equipment is essential to ensure product conformity, the organization shall determine the software requirements...and implement processes to ensure that monitoring and measuring equipment is fit for its intended use."

This applies to:

• Document control/management systems
• Training management and tracking systems
• CAPA/non-conformance databases
• Complaint/adverse event systems
• Risk assessment tools
• Statistical analysis software
• Calibration tracking systems
• Production scheduling systems with quality functions
• Traceability systems

The problem: Missing validation documentation is a gap, regardless of whether the software actually works correctly. FDA will expect:

• Documented requirements for the software
• Evidence of validation performed (not just operational use)
• Change management for software updates
• Risk assessment if validation was deferred
• Revalidation criteria and process

Validation approach should address:

• Software requirements and intended use
• Validation methodology (testing approach, test cases)
• Test results and acceptance criteria
• Change control procedures
• Revalidation triggers (system changes, bug fixes, version updates)
• Risk-based extent of validation

How to avoid it:

• Inventory all software used in QMS functions
• Assess validation documentation for each system (often inadequate or missing)
• Create or update validation documentation as needed, aligned to validation requirements and risk
• Document the validation approach, not just test results
• Establish criteria for revalidation on software changes (patches, version upgrades, configuration changes)
• Maintain validation files as part of QMS records (inspectable)
• If systems were implemented without validation, consider conducting retrospective validation with documented justification

Operational Mistakes

Mistake 9: Implementing Risk Management as Paperwork

The mistake: Adding risk references to procedures and creating risk assessment forms without actually using risk to make decisions.

Why it happens: Companies recognize that QMSR and ISO 13485 require risk-based thinking but don't know how to operationalize it. They default to documentation as compliance evidence.

The regulatory requirement: ISO 13485:2016 integrates risk-based thinking throughout the standard (Clauses 4–8), not just in design phases. 21 CFR Part 820 emphasizes risk-based decision-making across supplier management, process validation, and inspection approaches.

The problem: Investigators can tell when risk management is theater. If:

• Every risk assessment concludes "proceed as planned" with no controls
• Risk scores don't correlate with extent of control implemented
• Risk assessment language appears in procedures but never in actual decisions
• Decisions are made, then risk assessments documented to justify them retroactively

...the process isn't real, and investigators will cite the gap.

Real risk-based thinking requires:

• Risk assessments inform actual decisions (design choices, supplier selection, control selection)
• Higher-risk items receive proportionally greater controls
• Documentation shows the decision-making thought process (not just results)
• Different risk levels lead to observable operational differences

How to avoid it:

• Use risk assessments to actually inform decisions
• Document in decision records how risk assessment influenced the choice
• Ensure control extent clearly correlates with risk level (e.g., "Supplier A poses high risk (new, unproven, similar defect history); implemented enhanced testing protocol—100% incoming inspection vs. standard AQL sampling for Supplier B")
• Include risk discussion in decision records, not separate documents nobody reads
• Require management sign-off on risk-informed decisions, especially for trade-offs (cost vs. quality, schedule vs. safety)
• In management review, discuss risk-based decisions made during the period as evidence of dynamic risk management
• Train personnel on the "why" of risk-based controls so behavior aligns with documentation

---

Mistake 10: Not Training Personnel on Changes

The mistake: Updating procedures without training the people who execute them. Procedures change; behavior doesn't.

Why it happens: Time pressure. Training takes time, and the deadline is approaching. Procedure updates feel more urgent than training execution.

The problem: Procedures that aren't followed are actually worse than no procedures—they demonstrate you know what you should do but don't do it. FDA will cite this as non-compliance with your own procedures.

Specific training gaps we observe:

• CAPA procedure changes (CA/PA separation, new triggers, different workflows)
• Management review participation requirements
• Risk assessment integration into decision workflows
• QMS software changes (document control, training, CAPA system updates)
• Supplier risk assessment and monitoring
• Internal audit scope expansion (ISO 13485 requirements)
• Customer communication procedures (new requirement)

How to avoid it:

• Include training in your transition plan from the start (not as an afterthought)
• Prioritize training on operationally significant changes (not administrative updates)
• Verify understanding, not just attendance (e.g., practical exercise, competency assessment)
• Update training records to document competency, not just attendance
• Schedule training before procedure implementation whenever possible
• Conduct refresher training for key processes annually
• Use training as a management review input (discuss training compliance and effectiveness)

---

Mistake 11: Forgetting Customer Communication and Feedback

The mistake: Focusing on the high-profile changes (CAPA separation, record preparation) while ignoring new requirements like customer communication procedures and feedback systems.

Why it happens: These are truly new requirements without direct QSR equivalents. They're easy to overlook when focused on transitioning existing processes.

The regulatory requirement: ISO 13485:2016 includes explicit customer-focused requirements:

• Clause 7.2.3 – Communication: "The organization shall determine and implement effective arrangements for communicating with customers regarding: (a) product information; (b) inquiries, contracts or order handling, including modifications; (c) customer feedback, including customer complaints."
• Clause 8.2.1 – Customer satisfaction: "The organization shall determine what it needs to do to achieve customer satisfaction."
• Clause 8.2.2 – Internal and external audit (feedback): Procedures must address feedback mechanisms.

These are inspectable, documented requirements.

The problem: Missing procedures entirely is a clear gap. Companies often address only complaints (QSR-equivalent) but miss:

• Formal customer communication procedures (regulatory updates, product changes, recalls)
• Proactive customer feedback solicitation (not just complaint-driven)
• Feedback loop closure (communicating resolution to customers)
• Feedback trend analysis as management review input
• Feedback integration into design review and preventive action processes

How to avoid it:

• Use a comprehensive gap analysis that covers all ISO 13485:2016 clauses, not just those with QSR equivalents
• Don't assume QSR coverage equals QMSR coverage
• Specifically verify:
  • Customer communication procedure exists (Clause 7.2.3)
  • Customer feedback system exists and captures non-complaint feedback (Clause 8.2.1)
  • Feedback is analyzed for trends
  • Feedback results in corrective or preventive action (Clause 8.5.2/8.5.3)
  • Feedback is addressed in management review
• Document procedures addressing how feedback is solicited, received, analyzed, and closed
• Train personnel responsible for customer interface on communication requirements

---

Mistake 12: Applying One-Size-Fits-All Templates

The mistake: Downloading generic ISO 13485 templates and implementing them without adaptation to your specific operations.

Why it happens: Templates seem efficient. Why develop something from scratch when a template exists?

The problem: Generic templates may not reflect how your organization actually works. They may:

• Include requirements that don't apply to your business model
• Miss requirements specific to your products or processes
• Fail to address your suppliers, customers, or operational realities
• Not help when an investigator asks why your procedure says what it says

Personnel won't follow procedures they don't understand or that don't match operational reality.

How to avoid it:

• Use templates as starting points, not final products
• Adapt to your specific operations and products
• Remove or modify requirements that genuinely don't apply (document why)
• Add requirements specific to your risk profile or operations
• Have process owners and operators review procedures for clarity and accuracy
• Ensure personnel understand what procedures require and why
• Document applicability decisions (e.g., "Clause 6.2 Personnel: We do not require a human resources department; personnel competency is managed by Production Manager and Quality Assurance Manager")
• Update procedures based on actual operational changes (not just regulatory changes)

Conclusion

QMSR compliance is achievable, but only with focus on operational substance, not documentation cosmetics. The mistakes outlined here reflect common patterns in industry transitions, and all are preventable with prioritized execution.

The core principle: Treat QMSR as a fundamental operational shift requiring risk-based decision-making, substantive CAPA redesign, and inspectable records—not as a renaming exercise for existing QSR systems.

The timeline is fixed. February 2, 2026 is a hard deadline. Waiting for additional FDA guidance, perfect procedures, or "better timing" consumes the transition window without progress. Implementation based on reasonable ISO 13485 interpretation, adjusted as guidance emerges, is the practical path to compliance.

Companies that prioritize operational gaps, resource appropriately, and focus on substantive compliance will be inspection-ready. Those that treat QMSR as a documentation exercise will face findings, rework, and potential enforcement action.

The choice is execution today vs. remediation later.
