This module will continue to further develop a student’s understanding and application of systems engineering (SE) from the basic introduction provided in the second year module Engineering Systems (WM204). This will extend the coverage of SE to include the whole system life-cycle and seek to develop the student’s ability to apply the techniques of SE to real-life problems. The module will further develop Concept Development (discussed inWM204) by describing the early stages of the system life cycle in which a need for a new system is demonstrated, its requirements identified, alternative implementations developed, and key program and technical decisions made. Engineering Development will then be covered and will describe the later stages of the system life cycle, in which the system building blocks are engineered (to include both software and hardware subsystems) and the total system is integrated and evaluated in an operational environment. The role of SE in Post-development, (describing the roles of SE in production, operation and support phases of the system life cycle) and what domain knowledge of these phases a systems engineer should acquire, will be identified and developed through the use of examples.
