EPSS: What Does It Mean to You

Electronic Performance Support System(s), or EPSS, automates three types of traditional performance support for software users: training, documentation, and help desks. Integrating these support mechanisms into software--using wizards, clear and simple interfaces, and various forms of embedded user assistance--allows novice users to perform competently with minimal help from training, documentation or calls to help desks.
