In the development of complex systems the requirements for the system will almost always remain uncertain late into the software development. In gas turbine engine control systems at Rolls-Royce, typically 50% of requirements will change between Critical Design Review and Entry into Service. Ignoring or not planning for requirements uncertainty will cause(More)
A complex system's requirements almost always remain uncertain late into its software development. In gas turbine engine control systems at Rolls-Royce, for a traditional project (non-product line) typically 50% of requirements will change between Critical Design Review and Entry into Service. Requirements uncertainty is particularly relevant when(More)
