The focus of the course and the examples used span a variety of technologies. Indeed, systems engineering can be viewed as technology-independent principles and methods of the engineering of systems.
The system used for all the courses, through requirements analysis and through design, is an Emergency Communication Buoy. In Requirements Analysis, of course, the technology is not relevant. In design, system solution normally has a mixture of technologies which delegates can choose, including mechanical. We do a “dry-run” mini-workshop, in which the example used for logical and physical design is mechanical, involving Archimedes Principle. Delegates are free to choose a requirement to which relates any aspect(s) of solution technology. The value model building part of the trade-off study course is technology-independent, whilst the trade-off study itself involves various technologies. The first design optimization trade involves trading increased size for improvements (mostly) in other Measures Of Effectiveness (MOEs).
More generally, examples are chosen during course delivery to match, as much as practical, the technology and application interests of the group.
