TRAINING is the glue that determines how well the system holds up. Training is much more than just showing a client a few ways to move a mouse via voice. Training is complete when the client demonstrates Independent performance of a defined goal.
To be effectual, training must contain a core of components: (1) reference point, (2) goals, (3) knowledge/devices & (4) application. (1) & (2) define where the client is and where he's heading. (3) identifies the tools with which to accomplish the transition and (4) is the proof of the pudding – the hands-on which the client must perform to demonstrate success.
