When people don't do their job properly?

They don’t know why they should do it
Solution: Some people will blindly follow rules, but most want to know the “why” behind something that they are asked to do. It they believe a task or process is x (insert label here: low importance, arbitrary, a waste of time, or just plain stupid), no amount of training will effect a change in behavior. You might get begrudging compliance but that is about it. To get commitment, you have to explain the “why” to change the belief. (Until they believe his IS important, worth my time, etc.)
