Medical device quality management system: a practical guide
A medical device quality management system (QMS) is the set of documented processes, responsibilities and records a manufacturer uses to design, make and support safe, effective devices. ISO 13485:2016 is the international standard for it, and since February 2, 2026 the FDA's Quality Management System Regulation (QMSR) incorporates that standard by reference.
What it covers
The core processes every device QMS needs
Document and record control
Controlled procedures, work instructions and forms with review, approval and version history, plus records that prove the processes were followed.
Design controls and risk management
Planning, inputs, outputs, verification, validation and design transfer, tied to an ISO 14971 risk management file.
Suppliers, production and nonconformance
Supplier qualification and monitoring, process validation, handling of nonconforming product, and change control.
Feedback, complaints and CAPA
Complaint handling with reportability decisions, corrective and preventive action, internal audits, training and management review.
How to build one
A sensible order of work
- 1Define the scope: your devices, markets and which regulations apply (for example FDA QMSR, EU MDR, MDSAP).
- 2Write a quality manual and top-level procedures mapped to ISO 13485:2016 clauses.
- 3Stand up document control and training first — every other process depends on them.
- 4Add design controls, risk management, supplier control, complaints and CAPA as your products require.
- 5Run an internal audit and management review before any certification or FDA inspection.
