Abstract:

How can we choose among customer data collection methods when limited staff and financial resources must be spread across the whole development cycle? This tutorial helps participants understand the tradeoffs, so they can make effective choices among methods at different points during product design and development. It focuses on early user-centered intervention to gain cost-effective, reusable end-user information.
