Like creativity, it is stifled by pressure and targets. It's rare that people think it effective to instruct others to "be creative", and yet it is quite common to instruct others to "be more efficient", and to even set targets for that efficiency.
To get your employees to make processes more efficient:
- let them know that efficiency is important, and that it's something that should be seized where opportunity arises
- give them space to be efficienct
- give them time to be efficienct
- give them the confidence to be efficienct, that they can make mistakes without fear
