Abstract: This paper presents a
lightweight form of usage-centered design that has proved particularly
effective in designing highly usable Web-based applications. Fully
compatible with both traditional object-oriented software engineering
methods and newer agile techniques such as Extreme Programming, this
approach employs rapid, card-based techniques to develop simplified models
of user roles, tasks, and user interface contents. The process attempts to
resolve the conflict between the demands of rapid iterative design and
incremental development on the one hand and the needs for integrity in a
user interface fitted to the full set of user tasks on the other. The
resolution depends on creating a navigation architecture and a visual and
interaction design scheme based on quick but comprehensive task modeling.
The process is illustrated with experiences from the design of a
Web-deployed application for classroom teachers. |
