“Adding manpower to a late software project makes it later.”
The Mythical Man-Month – also regarded as the Bible of Software Engineering, is the book by Fred Brooks with the central theme based on Brooks Law mentioned above. It says that the man-month relationship is a myth = where-in the concept is that a unit of work proportional to the number of people working multiplied by the time they work. This concept would work for the kindergarten math problems where the work is to build a house or dig a well. But would definitely require a lot more contemplation when dealing with software projects.
The factors like – the time required for the new programmers to learn about the project and the increased communication overhead, will consume an ever increasing quantity of time.
I have heard high recommendations about this book from one of my colleagues and after reading much details about it, it’s definitely another addition to my to-read list.
