It is very important to know the difference between verification and validation plan while working in medical device company. It was also not clear to me in the beginning but once after working on a project during capstone, it became simpler to understand since we had to write these plans for our project. Basically, verification is matching all your outputs to the inputs of the product and validation is making sure the product does what customer has asked for. As an example, lets say customer would like to find deformation of something. That would be one of the customer needs. As design inputs you would use strain gauges and get the output. When you check if the strain gauges worked accurately or not, that’s verification. When you check if the product is giving out deformation, which would be validation.
