Different Systems Engineering techniques and approaches are applied to design and develop Command and Control solutions for complex problems. Command and Control is a complex sociotechnical system where human commanders make sense of a situation to support decision making, planning and distribution of orders with decision support and communication systems. The complex and dynamic operational environment make Command and Control systems difficult to develop. A modelling and assessment methodology in support of Systems Engineering is required to understand the behaviour and underlying structure. It must capture the dynamic interaction as well as the effect of humans performing work in a complex environment. Cognitive Work Analysis and System Dynamics are two complementary approaches that can be applied within this context.
