My other skill (apart from IT) is saxophone. Over the years I have noticed that if I can get my students to purposefully play a mistake it makes the mistake conscious. Then they can go about getting it right. If, on the other hand, If I just try to get them to play it correctly the success rate is much lower. This is akin to Steve's showing "video evidence" to his volleyball players. I think a lot of our IT or management practices are based in habits that were formed long ago. Sometimes habits are just bad habits, but often habits that were formed in a different set of circumstances that don't translate well into our current situation. Yet we just keep hammering away as we have always done. Until hopefully someone comes along and points out a better way or even a slight shift that makes all the difference in the world. A good work environment encourages this kind of collegial help between everyone involved in a project, and I've noticed that I have to be open to receiving suggestions as well as giving them.
