There are many employees (if you want to call them that) that love their job so much that they just don’t care what the incentive is. They just want to excel at what they do. They just love the work they do. And that’s the kind of employee one should ever want in their team for the right job. No incentive ever helps if the person you employed doesn’t love doing “what you expect them to do”.
There are different styles of processes, and the techniques to handle those will have to differ. And all will continue to exist.
