A Brief History of Agile

The history of agile software development is not what most people think, and is nothing like the story pushed by most Agile Evangelists.

Our latest publication A Brief History of Agile shows that from the beginning of large system software development the people managing the software engineering understood the need for prototyping and iterative and incremental development. This approach has always been part of the way good software is developed.

The environment the authors of the early papers referenced and linked in the article were operating in, satellite software and ‘cold-war’ control systems, plus the limitations of the computers they were working on, did require a focus on testing and documentation – it’s too late for a bug-fix once WW3 has started…..  But this is no different to modern day control systems development where people’s lives are at stake. Otherwise, nothing much has changed, good software is built incrementally, and tested progressively,  

The side-track into ‘waterfall’ seems to have bee started by people with a focus on requirements management and configuration management, both approached from a document heavy bureaucratic perspective. Add the desire of middle-management for the illusion of control and you get waterfall imposed on software developers by people who knew little about the development of large software systems. As predicted in 1970, ‘doing waterfall’ doubles to cost of software development. The fact waterfall survives in some organisations through to the present time is a factor of culture and the desire for control, even if it is an illusion.

The message from history, echoed in the Agile Manifesto, is you need to tailor the documentation, discipline, and control processes, to meet the requirements of the project. Developing a simple website with easy access to fix issues is very different to developing the control systems for a satellite that is intended to work for years, millions of miles from earth.
