Two terms, side by side

Pick any two terms to see definitions, context, pitfalls, and sources in parallel.

Quality & Risk

Quality Management System Regulation(QMSR)

In one line

FDA's harmonized successor to the QSR, incorporating ISO 13485:2016 by reference.

Definition

Issued in 2024 and effective in 2026, the Quality Management System Regulation amends 21 CFR Part 820 to incorporate ISO 13485:2016 by reference, with additional FDA-specific requirements for records, labeling, and complaint reporting.

Why it matters

QMSR aligns U.S. quality system expectations with international practice, but adds U.S. specificity. Manufacturers must reconcile procedures, terminology, and records strategies before the effective date.

Common pitfalls

•Assuming ISO 13485 conformance alone is sufficient under QMSR - FDA-specific provisions remain.

Quality & Risk

Quality System Regulation(QSR / 21 CFR 820)

In one line

FDA's current good manufacturing practice (cGMP) requirements for medical devices.

Definition

The Quality System Regulation (21 CFR Part 820) sets out the cGMP requirements that govern the methods used in, and the facilities and controls used for, the design, manufacture, packaging, labeling, storage, installation, and servicing of finished medical devices intended for human use.

Why it matters

FDA has harmonized the QSR with ISO 13485:2016 in the Quality Management System Regulation (QMSR), which becomes effective in 2026. Manufacturers must align procedures with the new framework.

Why compare MedTech terms side by side?

MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.

Common comparison patterns

Regulatory pathway choice - 510(k) vs PMA, 510(k) vs De Novo, Abbreviated vs Special 510(k).
Quality systems - QSR vs ISO 13485, QMSR vs QSR.
Software classification - SaMD vs SiMD, Locked vs adaptive AI.
EU frameworks - MDR vs IVDR, CE Mark vs UKCA.
Cybersecurity artifacts - SPDX vs CycloneDX SBOM, CVE vs CVSS.
Post-market actions - Recall vs field action, Removal vs correction.
