DESCRIPTION
Argues that traditional usability testing is too slow and expensive to properly support an iterative approach to design. Presents the "design checkpoint" as a complement: an informal exercise in which 1 designer meets with 1 user for 1 hour every 1 or 2 weeks. From the "7 Minute Soapbox on User Experience" in Waterloo, Ontario on June 14/07.
