At Roberts Express, for example, this is done by putting top customer service agents together with course developers and having them develop courseware as a team. In other companies training technicians on monitoring industrial processes. The training cases they look at in animated versions of control devices are replays of incidents which actualy happened on digitally controlled equipment. The net version is just a replay of an actual event. There are clearly some ways in which the training itself is better when delivered over the net.
Trainees can get information closer to the point where they put it to work.
That helps a lot in the transfer part of training. There's some evidence that folks who learn something in context and with some effort at discovery on their part, learn their lessons better. There's another almost invisible benefit here for some companies. In a classroom-based training corporate world, instructors are often flying from place to place to conduct training. Often they arrive, tired and jet-lagged.
