To build upon user-centered design methods, we used a collaborative and multi-modal approach to involve users early in the design process for a website. This article presents our methods and results and addresses the benefits and limitations of the Collaborative Prototype Design Process (CPDP), including ways in which this new method can be implemented. The CPDP is an innovative approach to user-centered website design that emphasizes collaboration, iterative testing, and data-driven design. The CPDP balances the power and needs of users with those of designers and, thus, enables design teams to test more tasks and involve more users. We divided our initial team into three independent design teams to separately profile users, test usability of low-fidelity paper prototypes, and then create and test usability of resulting wireframes. After completing the user-centered design and usability testing, the three teams merged to analyze their diverse findings and create a final prototype.
