When I think of retention I think of elementary school days as to when students were retained because their grades were not adequate to advance the next grade or class. This is the negative connotation of the word. The positive side is knowing that something is producing well or effectively working well. An example is an employee you have had for 10 years and they are excellent at managing people. The employees are happy and content with the PM in charge. The PM also loves exciting and challenging tasks. Therefore, retaining a PM like this every companies dream, perhaps. The question then becomes is the PM happy at staying at the job or company? If that’s the case then retain the PM because she or he skills will be a competition to other companies to do well.
