Getting the Requirements: Techniques and Experiences Capturing Requirements for Several Real-Time Applications

摘要

This paper discusses techniques used and experiences gained while gathering and documenting the functional requirements for several control systems and one engineering database system. This work was performed in the Atomic Vapor Laser Isotope Separation and Security programs at Lawrence Livermore National Laboratory over a period of three years. Teams of from one to four engineers gathered requirements for a large laser control system, several separator control and diagnostic systems, a security system, and an engineering database system. These systems required gathering requirements data from physicists, electrical, mechanical and material engineers, and in the case of one security application system, police officers. The paper discusses team structure, the advantages of larger teams and problems with one person teams. It defines the interview, document, feedback and critique cycle used for requirements acquisition. (ERA citation 12:040282)
