Designing through Data: How Formative Testing and Summative Testing Lead to Understanding User Needs and Creating Successful Products | Stephen Nelson

Stephen Nelson, IDSA, will focus on formative and summative user testing as they relate to medical device design in a large organization, with case studies from digital interface design and physical hardware design.

Nelson will show the use of prototyping as a tool to gain deep understanding of customers’ needs for the product, and their workflow, in methods and rationale between formative and summative testing, and how they relate to the documentation needed to submit a product for regulatory approval.  He hopes to spark a conversation about the place of design within the development of a medical device.
