Scenario Direction Domain

As we build a modeled system, we will want to evaluate it while it is executing.

We define a scenario director domain to let us specify scenarios that we can run against a completed model.

The concepts and activities necessary to run a scenario actually have little to do with the internal design or modeling of a system under test of evaluation.

So rather than extend the SM Metamodel with yet a scenario management subsystem, we split it off into its own domain.

This means that we need to defined a vocabulary to reflect a set of concepts orthoganal to what we have in the metamodel.

So concepts like domain, class, external event, and so forth are properly part of the meta model and not scenario direction.

We do define terms such as scenario, direction, actor, stage and so forth which may be configured to represent our active metamodeling elements.
