What is Brooks' Law?
Brooks' Law refers to a well-known software development principle coined by Fred Brooks in The Mythical Man-Month. The law, 'Adding Manpower To A Late Software Project Makes It Later', states that when a person becomes one Project team is added and the project is already late, the project time is longer rather than shorter.
Brooks Law can be used for two main reasons:
The 'ramp-up' times required by new project members for productivity due to the complexity of software projects are complex. This takes existing resources (personnel) away from active development and places them in training roles.
An increase in the number of employees increases the amount of communication required, including the number and variety of communication channels.
