Design controls


Design controls designates the application of a formal methodology to the conduct of product development activities.
It is often mandatory to implement such practice when designing and developing products within regulated industries.

Medical devices

Since 1990, the Food and Drug Administration has required that medical device manufacturers that want to market certain categories of medical devices in the USA follow Design Control requirements. At a high level, this regulation requires:
The Medical Devices Directive similarly lists several requirements regarding the design of a medical device.
ISO 13485 is a voluntary standard that contains section 7.3 Design and Development recommending which procedures should be put in place by manufacturers in order to have a quality system that will comply with MDD 93/42/EEC.
The objective of Design Controls, in this context, is to require that manufacturers follow a methodologically-sound process to develop a medical device, with the intent of improving the probability that the device will reach an acceptable level of efficacy and safety.
