Activity: Review Business Object Model

Recommended Review Meetings

If the model is large, you will have to examine different aspects of the business object model at separate review meetings. The following meetings are recommended:

• Review of the survey of the business object model, not looking at details of the business workers and business entities.
• Review of the business use-case realizations.

Checkpoints for the Business Object Model
