This is a very common and intuitive response to a schedule slip in a project. Surprisingly after additional manpower is added the project actually slips later. Brooks’ Law is often cited to refute the common myth; stating ‘adding manpower to a late software project makes it later’ (Fred Brooks – The Mythical Man-Month). While an oversimplification, it is a good rule of thumb. The counter-intuitive result of a later project is due to the increase in necessary communication between the team; which increases exponentially as additional people are added to a team. |
