ABSTRACT Electronic performance support systems (EPSS) deliver relevant support information to users while they are performing tasks. The present study examined the effect of different types of EPSS on user performance, attitudes, system use and time on task. Employees at a manufacturing company were asked to complete a procedural software task and received support from either an intrinsic, extrinsic, external performance support system or no system at all. Results revealed significant differences on performance, attitudes and use between several treatment groups. The study suggests that providing any kind of EPSS to support task performance is better than having none at all. In addition, designers can improve user performance, attitudes and use by creating systems that integrate with the primary work interface.
