FAIT: a systematic methodology for identifying system design issues and tradeoffs

As the role of automation in complex systems grows, so does the complexity of the system design process. Unintended consequences of automation may arise from unforeseen system failures, human errors, miscommunication between human and machine, and a great many other aspects of the interactions, among human, machine, and environment. To address these concerns, a methodology to identify and prioritize design issues associated with complex systems, called the function allocation issues and trade-offs process, is presented. The process is intended to be used very early in system design as an aid in allocating design resources and evaluating system concepts.<
