To create an object-behavioral model, the analyst performs the following…

Correct answer summary: The object-behavioural modelling process involves evaluating all use-cases, building state transition diagrams for the system's stateful objects, and reviewing the object behaviour model for accuracy and consistency.

Key steps and why each matters:

• Evaluate all use-cases: Use-cases reveal scenarios, actors, events and responsibilities. Extracting objects and the events that affect them starts here.

• Build state transition diagrams for the system (or individual stateful objects): These diagrams show states, events, transitions and actions, capturing object behaviour over time.

• Review the object behaviour model to verify accuracy and consistency: Check that events, states and transitions match the use-case scenarios and that there are no contradictions or omissions.

Why the other statement is not correct as written:

• The statement that says to "identify events that do not derive the interaction sequence" is incorrect or poorly phrased. In practice you identify events that drive or trigger interaction sequences; saying "do not derive" contradicts that purpose. Identifying events is part of use-case analysis, but the phrasing here makes the item invalid.

Practical order: Evaluate use-cases to find objects and events → identify interactions and events that drive sequences → create state transition diagrams for stateful objects → review and refine the behaviour model.
