Evolution of the systems integrator role and change management process within highly integrated aircraft systems

Aviation began with a simple Wright Flyer that relied on only three systems: aircraft structures, mechanical flight controls and a bicycle-inspired sprocket chain-driven engine. The project was one that a small team could manage without even worrying about the concept of “Systems Integration”. The very thought of documenting interfaces and establishing change management process would have added unnecessary complexity to the development process and would have seemed absurd to the Wright Brothers. Since that time, aircraft have evolved into complex, highly integrated system of systems designed and built by teams of tens-of-thousands. This has led to a change in aircraft systems integration methods and processes.
