Who are the right users to be involved in the design process of health products

The misuse of medical products can cause harm to the health of patients and other users. Many international standards are practiced in the medical product development industry to ensure quality and safety, including guides and models with various ways to engage the user in the development process. There are methods that can be performed at any stage of development, which hampers the project-planning phase. Nevertheless, there is a lack of information that helps companies select the most appropriate users, according to a particular profile or attribute. In order to demystify how users can be involved in the development of the product for health and using case studies in the literature as a basis, this research aims to present the recurrent activities that users perform when involved in development of medical devices. The main contribution of this word is the model of user tasks crossed with users characteristics developed.
