This paper describes a project that uses real-world computer-troubleshooting scenarios to test and expand upon the latest research and technical knowledge in the area of procedural content development. Our goal was to improve the effectiveness of on-line help procedures for solving computer problems experienced by novice to intermediate computer users. Our focus was not just on writing techniques. We also focused on presentation aspects such as the structure of the content, use of graphics and screenshots. The outcome of the project is to develop procedural writing and presentation guidelines and to apply them to developing future support content, which we believe will lead to increased success of the target user. Prototypes based on the guidelines were usability tested with one prototype released on our public site. These tests showed positive results.
