The challenge for most organizations is that the use of technology to drive human performance is relatively new and not well understood. To gain insight on the sort of e-performance solutions that practitioners are using, TechEmpower spoke with some 150 people from nearly 50 companies. We found numerous and varied examples of e-performance, but there was little consistency in the descriptions of similar solutions. In general, it was difficult to know what worked--and what did not. It soon became clear, though, that most success stories involved quick, targeted implementations, such as self-service action and development planning. Here are four case studies that illustrate a variety of approaches that may help you identify options and your own quick wins.
