SYSE.5:1 - Problem Frame

An engineered System participates in a use situation through interactions under stated conditions. A desired outside effect can often be produced by several functional organizations, and one functional contribution can often be borne by several Systems together. Conversely, one System can bear several contributions in one configuration and different contributions in another. Distribution can change, for example, across operating modes, failure states, product variants, sites, and time.

The engineer therefore needs more than functional decomposition and more than a component search. The working result links functional and constructive candidates to their outside use, proposed allocations, interface realizations, placement, integration dependencies, and evidence. The result table below states its required content. These selected structures answer different questions and need explicit correspondence where the decision depends on them.
