Summative Usability Testing
Summative testing is more than confirming a product meets the needs of its users. Summative testing demonstrates that all the hard work has paid off in confirming that your product is safe and effective. A summative test allows representative users to complete tasks using a production model of your product (or its functional equivalent). Summative testing is the only place where “everything comes together” to make sure, before it reaches the market, that a product can be used safely and effectively. We like to say that during summative testing there should be no surprises and nothing more to learn about your product. Passing a summative test gives confidence that your product can be used, and used safely.
