No not at all..
The reason behind this is, the concept of “Nice guys finish last” which is followed by most in managing the project. It drives me crazy, and its totally unpleasant. It will set a false expectation to your team. If you are a manager and assigning a task to someone if he/she finishes it on time then it doesn’t mean that every time that the given task is simple. Never quantify the nature of work based on the time spent on that. Always rely on the result and rewrite your perception “Nice guys brings best results”.
