Beyond User-Centered Design and User Experience: Designing for User Performance  

The shortcomings and limitations of user-centered and user experience design are considered and contrasted with usage-centered design. The iterative, trial-and-error approach of traditional user-centered approaches is argued to lead to excessive dependence on user testing and user approval, leading to overly conservative designs. By contrast, model-driven approaches based on fine-grained task models have a proven record of leading to dramatic improvements in user performance through innovative designs.

Success Factors in Developing Electronic Performance Support Systems (EPSS)  

This session examines the factors that underlie a successful implementation of an electronic performance support system (EPSS). It introduces the concept of performance support and differentiates between supporting a software application and supporting a person performing work. An electronic performance support system being used in a major corporation to improve the performance of documentation developers is demonstrated. The results of a survey of implementors of electronic performance support systems to gague success factors is presented.
