For Capstone II, I had to make up a test method to validate the product. I don’t remember having to use a specific set of criteria for validation. When I had to do it along with my team, we thought of what could be done by ourselves to validate our design. For example, I was responsible for the mechanical properties of the product. So what I did was I suggested Instron testing. Another property I had to validate was its stability when worn, I thought to myself how to do this and I came up with a test method where I had to wear the device and do certain movements to see if the device had moved from its original location. So, I believe there is no real criteria for it because of the nature the feature/characteristic that needs to be validated.
