It is important to verify that the model is correct and complete at intervals throughout analysis.
Model confirmations become increasingly important as you near the completion of this development phase. It is especially important to ensure the model is ready for continued refinement during the next phase of system development. Apply confirmation techniques systematically before proceeding with design activities.
CA Gen provides facilities to support confirmation techniques. However, confirmation can never be completely automated. In particular, the Consistency Check facility performs much of this checking automatically. The toolset documentation explains this facility in detail.
Consistency Check can be run against:
In design, CA Gen performs automated checks and will not accept inconsistent model objects. The model must be completed and corrected before finishing analysis on any part of the model that a system will support.
The automated consistency check facility verifies that the model conforms to CA Gen rules and conventions. The confirmation techniques described in this chapter help the analyst to ensure that the meaning of the model is correct as well.
By the end of analysis, you should also have produced, confirmed, or modified the following:
