An EPSS is a software context that integrates the support needed to perform a job task--information, software, and expert advice--with the actual job task or tasks. EPSS's provide this support at the appropriate time and in the most appropriate format--ED4 (EPSS Define, Design, Develop, and Deliver). This book describes ED4 and the process that the instructional designers and software engineers used to create the Learning Services Workbench.
