Medical device manufacturers that contract for usability testing services are advised to develop an RFQ, which might also be called a request for proposal (RFP) or statement of work (SOW). The following is a list of some of the details to include in a request to conduct a usability test of a medical device:

• Test type: Specify which type of usability test you want the vendor to conduct. As discussed in “What is the difference between formative and summative usability testing?” and “What is a benchmark usability test?” in Chapter 6, common usability test types are formative, summative, and benchmark tests.
