Performance support systems can play an important role in corporations by managing and allowing distribution of information more easily. These systems run the gamut from simple paper job aids to sophisticated computer- and web-based software applications that support the entire corporate supply chain. According to Gery (1991), a performance support system improves employee performance by reducing the complexity of a task, providing information the employee needs to perform the task or providing the decision support that enables employees to determine what action to take under a specific set of situations. For trainers and instructional designers, performance support typically has taken the form of computer-based instructional design (ID) tools. Research and development in the field is dominated by authoring tools for the production and development of computer- and web-based instruction (van Merrienboer & Martens, 2002). More recently attention has turned to computer-based ID tools that support analysis and design activities as well as implementation and evaluation activities (van Merrienboer & Martens, 2002). Spector (2002) introduced the notion of Knowledge Management Systems as a type of computer-based ID tool. These tools support the collaborative activity that surrounds most of the design and development process. This article: (1) describes how TPMS supports Training Program Managers (PMs) who guide the development of the new product training; and (2) highlights the impact of the system on the performance of the PMs and the Customer Advocacy Training team of which they are a part.
