When is a Quality Management System (QMS) needed for Medical Devices?

A QMS for medical devices describes structured procedures and processes that cover all aspects of manufacturing, procurement, supplier management, risk management, complaints handling, and storing, distributing, and labeling clinical data in an organized and systematic manner. In Quality Management Systems, procedures and processes are used to organize data in a systematic manner.

Medical device companies sometimes have a hard time determining when to start setting up a Quality Management System (QMS). Moreover, considering that the time required to fully establish a QMS can range from 3 to 9 months, it becomes even more critical to know when it is best to do so. 

However, the right time for deploying a QMS can vary greatly according to numerous factors. Firstly, depending on the region you wish to market your medical device, secondly, whether you plan to register a technology or bring a device to market, and finally depending on the device classification type. In this article, we take an overview look of what a QMS is and when you need to have one in place.

Medical Device QMS: An Overview

What is QMS for Medical Device? (Quality Management System)

QMS Medical Devices: Everything You Need to Know: A QMS for a medical devices is a structured system for documenting the procedures and processes implemented throughout a part, or even the whole lifecycle of a medical device. It can cover a variety of aspects such as medical device design, manufacturing, supplier management, product labeling, storage & distribution, clinical data, risk management, and complaint handling. QMS standards are enforced in most of the world’s markets through ISO 13485: Quality Management System for Medical Devices, and the US FDA QSR: Quality System Regulation for Medical Devices.

Why is it Difficult to Determine When to Implement a QMS?

Typically, there is no formal requirement for a Quality Management System to be implemented from as early as the design and development stage. Many medical device developers in these early stages will work quickly to meet investor milestones or obtain an income through launching initial sales. Doing so, they sometimes don’t keep systematic records such as design controls or change management.

However, later on during regulatory submission of the device, they will need to demonstrate that from the beginning they had controls in place for developing the device. A Design History File (DHF) or a Technical file are prime examples. These requirements entail documentation of key aspects such as control of records, design history, basic SOP’s (Standard Operating Procedures), change control, and risk management. It is therefore imperative to maintain these records from early on, in order to be able to answer to any regulatory bodies challenging the device regulatory submission dossier. 

The Partial QMS Approach

Even though a QMS will meet the requirements mentioned above, medical device development companies may find it best to hold off full QMS implementation until absolutely mandatory. That’s because especially in the very early stages of development, a full QMS can be burdensome and hinder the flexibility required.

The best approach in this case is to implement a partial (or pre-production) QMS, where only the most important parts of a QMS are implemented. This way companies can have a systematic method of handling the critical parts of medical device development, without being burdened by a full blown QMS. This results in having adequate controls and documentation from the start, creating a quality oriented culture from early-on in the project, and reducing the difficulty of implementing a full QMS in the future.

QMS Requirements for Different Regions

United States

The US has its own set of regulations for medical device QMS, through the FDA QSR, or regulation 21 CFR Part 820. QSR proof of compliance is expected when companies go through the 510(K) process for a Class III medical device. However, the FDA will not require proof of QSR compliance at this stage for Class I and Class II devices, which is mandatory only after the device 510(K) process is complete and it is ready to be marketed in the US. 


The Canadian Ministry of Health requires conformance to ISO 13485, certified through an auditing process called Medical Single Audit Program (MDSAP). This means that a full QMS is mandatory before you can get a license for marketing your medical device in Canada. 


In Europe, obtaining CE Marking is mandatory for marketing medical devices, which means conforming to the new EU Medical Device Regulations. The easiest way for medical device companies to demonstrate conformance is through an ISO 13485 certification, resulting in the need for a QMS before submitting for a device market license.

Other Regions

Every big country such as China, Brazil, Japan, and others, has its own QMS requirements. In most cases those are based on the ISO 13485 standard or the FDA QSR regulation. This means that companies can have a clear goal for setting an ISO compliant QMS system to cover for every market. The only real challenge being when to implement it and in what degree, according to each specific case. 

A Solution to QMS Considerations

Simply by partnering with an established medical device development and manufacturing company can alleviate the hassle of establishing and maintaining your own QMS for medical devices. For example, working with Quasar grants you access to a long established QMS with demonstrable efficiency, including standard operating procedures, ISO quality system, audits support, and documentation. This way you eliminate the learning curve of implementing and managing a QMS from scratch, reducing complexity and saving up on both time & resources.
