''Rationale''

In recent years there has been a trend for all engineering disciplines to have tools that support the engineering work (design, analysis, visualisation) that use underlying models of the concepts in that domain. For instance, structural design moved from physical draughting drawings, to electronic versions of drawings, then to models of structures that could be re-rendered with plan, elevation views analogous to drawings. However such tools support other capabiliies, for instance, perspective projections of the structures, where the view can be dynamically rotated, assisting understanding.
Arguably systems engineering is the last engineering discipline to see this trend to model-based approach adopted. It is becoming clear that model-based systems engineering will be a necessary competency for systems engineers now and into the future.
