Our research was motivated by a concern for the users of today s complex productivity applications. We assumed that if we as expert users were struggling then average users and novice users must be really struggling. There was very little actual research however that indicated whether or not this was the case. We noticed at the time we began our work in 1998 that the terms bloat and bloatware were appearing with some regularity in the computer literature and in the popular press. Although these terms were never clearly defined they certainly implied that users were having a negative experience of functionality-filled software. But again there was very little research evidence to show that all users were experiencing complex software as bloated. If all users do not experience complexity this way as bloat then we wondered what were the factors that impacted the user s experience Is it for example expertise or the number of functions that are used Our main research objectives were three-fold 1 to gain a systematic understanding of users experiences with complex software 2 to move toward a new interface model that is derived from this understanding and 3 to evaluate the new interface model in light of the problems that users experience. In this chapter we describe research that was conducted to address the above three objectives and the methodology used to eventually arrive at a multiple interfaces design solution for a complex commercial word processor. We conducted three studies one was a pilot study and the other two were full user studies. An overview of our three studies is shown in Figure . In Study One we conducted a broad-based assessment of user needs. We worked with 53 users of MSWord 97. Based on our findings from Study One we created our first multipleinterfaces prototype for MSWord 2000 that
