In 1975, Frederick Brooks wrote a classic book on software project management called The Mythical Man-Month. In the book, he famously argued that adding more people to a development project will hinder rather than help to get things done faster. The reason is that having more people working on the project introduces a non-linear overhead in communication.
Five years before Brooks' book, a software development methodology called the Waterfall Model was coined. This approach applied the insights from mature engineering disciplines (mechanical, civil, etc.) to software. The idea was to construct systems by first gathering requirements, then doing the design, then implementing it, then testing, and finally getting it out the door in one linear sequence.
We have come a long way since then and learned a lot about making software. The Waterfall Model is now considered a flawed method because it is so rigid and unrealistic. In the real world, software projects have ill-defined and constantly evolving requirements, making it impossible to think everything through at once. Instead, the best software today is created and evolved using agile methods. These techniques allow engineers to continuously re-align software with business and customer needs.
