When to Perform Consistency Checks

A usual sequence of events is for you to:

• Develop, in parallel, the data and activity aspects of the analysis model
• Perform checks at intervals
• Analyze interactions and the completeness of the model

Because the modeling activities also enable you to detail interactions between activities and data, it is normal to require a progressively more detailed and consistent model of the data as a prerequisite to interaction analysis.

It is useful to perform consistency checks on the data and activity objects at regular intervals during analysis, and especially before:

• Completing an aspect of analysis and beginning a new analysis activity, for instance, developing a progressively more detailed and consistent model of the data and activities before moving to interaction analysis.
• Review
• Moving to design
• Business system definition

These tasks are shown in the following illustration.
