Requirements engineering in systems engineering practice

Advances in microprocessor and network technology led to the proliferation of complex systems with distributed processing and databases, internal communication systems, and heterogeneous components. The processing components can by themselves comprise a system or they may be embedded in a physical system. Both the encompassing system and the processing system are known as computer-based systems (CBS). Due to complex CBS dynamics and component interdependencies, current system engineering processes are inadequate. Problems with current practice are summarized, and a new solution is proposed
