In the early stages of product development it is crucial to understand users in order to create products that reflect their needs, desires, limitations and capabilities. This paper introduces a user-centered approach for interpreting users’ needs into actionable knowledge for product design. The proposed framework consists of multiple inter-related knowledge sets for representing users’ mental models in relation to product structure and function, and users’ procedures and context-of-use. Structure and function pertain to the product’s behavior and attributes; procedures refers to the tasks users engage in during product interaction; and context-of-use refers to the wide range of influences by which product performance can potentially be affected. The models are interpreted using an event script, an image representation, and a set of influences that allow developers to envision cause and effect, and thereby specify product performance specifications. A case study illustrates the framework and how this methodology can be applied.
