Module 6 - Use-Case AnalysisUse-Case Analysis StepsUse-Case Analysis Steps• Supplement the Use-Case Description• For each Use-Case Realization• Find Classes from Use-Case Behavior• Distribute Use-Case Behavior to Classes• For each resulting analysis class• Describe Responsibilities• Describe Attributes and Associations• Qualify Analysis Mechanisms• Unify Analysis Classes• CheckpointsMastering Object Oriented Analysis and Design with UMLCopyright © 2003 Rational Software, all rights reserved 5The above are the major steps of the Use-Case Analysis activity.First we must review the use-case descriptions developed in the Requirementsdiscipline. Chances are, they will need some enhancements to include enough detailto begin developing a model.Next, we study the use-case flow of events, identify analysis classes, and allocate usecaseresponsibilities to the analysis classes. Based on these allocations, and theanalysis class collaborations, we can begin to model the relationships between theidentified analysis classes.Once the use case has been analyzed, we need to take a good look at the identifiedclasses, making sure they are thoroughly documented and identify which analysis andmechanisms they implement.Last, but not least, we need to make sure that our developed Analysis Model isconsistent.6 - 5
