What is Software “Validation?”
Validation testing answers the simple question of “Are we building the right product?” This type of testing confirms that all of the users’ needs and intended uses for the device are met. Validation tests include, but are not limited to, usability, acceptance test, and, when necessary, comparing data with gold standards. Specifically, software validation almost always occurs in clinical, or patient-care, settings in which the finished medical device is used to ensure that it functions as it is intended to (i.e. control heart rhythm, measure heart rate, improve hearing, etc.).
The Importance of Software Validation
Software can be an essential part of your medical device, whether you are designing a brand new product or improving the functionality of an existing one. As medical device software continues to grow and expand across many new devices, patient safety must remain a top priority of medical device companies. The FDA is constantly monitoring and reporting on medical device issues, and failure to implement software controls or develop legitimate medical device software testing procedures can lead to issues within the software that ultimately cause a need for correction or removal of the device. A lack of software validation within the medical device developmental process can single-handedly alter patient safety, company reputation, and legal issues.
Software Validation Limits the Amount of Software Failure
Understanding the role that medical device software verification and validation (“V&V”) has in design, development and use is the first step to avoiding software failure and FDA recall. Although V&V testing is considered a critical part of the medical device development process, a lot of the time the value that it brings to medical device development is overlooked because it is not given the proper emphasis. All software (including software that has gone through V&V testing) is subject to failure after updates. This makes software validation critical at each point in a device’s life when its software undergoes a change. These changes within the medical device’s software are happening continuously to accommodate for technological advancements and evolving user needs, while also correcting existing errors within the software.
