QUALITY ASSURANCE (QA) AND QUALITY CONTROL (QC) ARE SEPARATE, BUT CONNECTED, PROCESSES THAT ARE CENTRAL TO THE OVERALL QUALITY SYSTEM AT ANY MEDICAL DEVICE MANUFACTURING COMPANY.

Medical device engineers sometimes use the terms "quality assurance" and "quality control" interchangeably, but a clear understanding of the difference between these two processes can bring clarity to the overall structure of the quality process in any medical device company. Quality assurance is a proactive process that focuses on defect prevention by progressively refining manufacturing processes, policies and procedures. Quality control is a reactive process that focuses on effectively identifying defects in completed products before they can be shipped to customers.

QUALITY ASSURANCE: IT'S ALL ABOUT THE PROCESS

Quality assurance can be defined as the activities for ensuring quality in the processes by which products are developed. This proactive process includes many methods, all with the purpose of preventing defects in the final product. Effective quality managers engage in quality assurance by improving product development and testing processes so that defects do not arise when the product is being developed.

The QMS itself is a quality assurance tool, serving as a record of all quality policies and procedures that go into creating the final product. Purchasing controls ensure that the raw materials used to manufacture a product consistently meet acceptable standards. Production and process controls are designed to create uniformity and consistency in the manufacturing process, helping to ensure the consistent production of quality goods.

QUALITY CONTROL: IT'S ALL ABOUT THE PRODUCT

While much of your QMS will be focused on assuring the quality of processes, quality control represents a set of activities that focuses on identifying defects in the products that you create. Quality control is typically the last controlled process that a product will go through before it is shipped. As such, an effective quality control process acts as a buffer between defective products and the customer. A perfect QC process would ensure that defective products are always identified and never make it to a store shelf or into the hands of a customer.

Quality control is typically handled by a specific person or team that tests finished products against predetermined acceptance criteria to determine whether the product conforms to specified requirements.

INTEGRATING QA, QC AND GREENLIGHT GURU QMS

Greenlight Guru QMS offers the ideal support system for both quality assurance and quality control procedures at your medical device company. Product specifications are created in the product development stage of your medical device and documented in your QMS under the Design Controls section. These specifications set the expectations for how your product can be effectively manufactured.

Purchasing controls, production and process controls, and training guidelines for staff all live in your QMS and will need to be continuously updated in response to any defects you discover. Internal audits are also an important aspect of quality assurance, and any FDA audit will require that you present the findings of any internal audits you have conducted.

Quality control feeds back into quality assurance through the CAPA process, whose documents are all stored in your QMS. A non-conforming product creates a need for corrective and preventive actions, leading to a root cause analysis and a refinement of your procedures to help reduce incidences of non-conforming product in your inventory. Greenlight Guru QMS acts as a single source of truth for quality within your organization, allowing all authorized staff members to securely access your QA and QC processes and data, and use that data to build more powerful systems that produce better medical devices.
