Collaboration with product teams in effective user-centered design  research and practice is rarely a simple process.   In this talk, David will review two recent case studies, showing how research findings and methods can be agents of positive change, and offer some general lessons learned.

Hendry, D. G. (2000).  How people read on the web? Documentation and Training 2000 , April 10-11, 2000, Boston University Corporate Education Center [Invited]. 

How do people read Web pages? By employing a range of usability engineering techniques, along with eye-tracking data, Lycos seeks to answer this question. We present a framework of claims about how people scan, parse and scroll Web pages when deciding where next to click. We illustrate this framework with real examples, which suggest the strengths and weaknesses of various design alternatives for structuring information. The framework represents general themes derived from observations of hundreds of people interacting with dozens of products.
