Model Verification and Validation : Model Inspection

Model Inspection

Several errors in the model can be detected by visual inspection. While this can be done on-line, it is more convenient to work from a hardcopy produced by printing the chart with the “With Elements' Dictionary” option enabled.

Common visual checks are:

Visual inspection should be done by the creator of the chart or by another engineer familiar with the chart(s) being inspected.

Model inspection should also include the “cleanup” of the design. (Refer to the Style Guidelines and Best Practices section.) It involves e.g. the definition of actions in order to make charts more readable, redrawing flows and transitions that cross unnecessarily, ensuring that actions are consistently placed either on transition labels or in static reactions, checking for items that can be relocated into the Global Definition Set, and compacting the chart hierarchy.
