The Mythical Man-Month is a concept developed by Fred Brooks while he was tasked with guiding a team of programmers to develop a new operating system dubbed the “360.”
Fred realized that adding more programmers because the project had fallen behind and was late, did not actually help get it done sooner, and actually caused further delay. He wrote about this concept in his book “The Mythical Man-Month” which was later named “Brooks law.”
IBM decided to discontinue production of OS/360 due to the hardware having memory limitations as well as the development taking much longer than anticipated.
Many of the structures, techniques and scheduling in the current software development environment is passed down from this epic failure in software programming.
