According to Allison Rossett and others, an electronic performance support system (EPSS) is a computer-based or an integrated electronic environment that is available to and easily accessible by users to improve their performance and learning. It facilitates skill and knowledge acquisition within a particular domain of study. As well as having pedagogic utility, an EPSS is usually designed and developed as an integrated support tool to assist employees by embedding performance and learning assistance within the system itself. It is structured to provide an immediate, individualized online access to full range of information, software, guidance, material, assistance, tools, data, and assessment and monitoring systems. The goal of an EPSS is to provide whatever is necessary to enhance or ensure performance and learning at the moment of need with minimal support from other people. It provides just-in-time or on-the-job access to integrated information, training, and learning experiences, to help enable users to achieve the optimum performance when and where needed, thus, also enhancing the performance of the overall work environment. This entry discusses the key characteristics and design of an EPSS, and its benefits and potential to improve performance.

Key Characteristics of an EPSS

A computer program or system should display key characteristics that are the minimum a program should have in order to be called an EPSS. Otherwise, it would not be different from any other computerized instructions or tools. First, an EPSS should be computer based to provide quick and easy access to the information just in time. This information may be in the form of text, graphics, audio, or video. Second, it should provide access to the discrete, specific information and tools needed to perform a task at the time the task is to be performed. Additionally, an EPSS should provide useful, job- or task-related information.

Another characteristic for an EPSS is that the user should be able to control it. There is usually no need for an instructor because the user is guided by the needs of the task at hand. The system should also be flexible, supporting inexperienced users with a minimum number of commands as well as experienced users with more procedures that may take longer to learn. The performance system should serve as an intelligent assistant responding to specific needs in reaction to various job and task requirements.

According to Rossett’s (2009) book First Things Fast, an EPSS should reduce the need for prior training in order to accomplish a task quickly and easily. The availability of information needed to perform a task reduces the need for much training. Other desirable characteristics of an EPSS include easy system updates, fast access to information, exclusion of irrelevant information, adaptation to different learning styles and knowledge levels, and integration of different learning experiences.

Overall Design of the EPSS

EPSSs are generally composed of a number of interrelated components, typically including an information database, an electronic advisory system, and applications or productivity software. The user interface for an EPSS should be intuitive since it provides direct connection between the user and software components. It should connect the major sections of the system to each other for ease of use and high accessibility. The success of an EPSS is dependent on its user interface since users need to access information quickly utilizing obvious navigation choices. The system should also be structured in a manner that allows different ways to access information.
