A team is maintaining an MBT model for a system that has undergone several requirement changes. The model is becoming inconsistent with the current requirements, and some elements are no longer traceable. What is the best approach to address this?

Remove the traceability links and rely on the model's structure to convey requirements.

Create a new model from scratch to avoid the complexity of updating the existing one.

Keep the model as is and document the inconsistencies in a separate document.

Update the model to reflect the new requirements and re-establish traceability links.

A team is working on an MBT model for a customer relationship management (CRM) system. They have states like 'New', 'Active', 'Inactive'. They are adding a state for 'Prospect'. What naming convention should they use?

Use 'Prospect' but in lowercase to differentiate it from other states.

Use 'Prospect' as it is clear and consistent with the existing single-word state names.

Use 'P' to keep it short and consistent with abbreviations.

Use 'ProspectState' to explicitly indicate it is a state.

A team is developing an MBT model for a banking application. They have made several assumptions about business rules and have linked model elements to requirements. What should they do to ensure the model remains maintainable and auditable?

Only document assumptions that are critical, and skip traceability to save time.

Use informal notes in the model without linking to requirements.

Keep the model simple and avoid documenting assumptions to reduce overhead.

Document all assumptions and decisions in a separate document and link model elements to requirements.

Which activity is part of validating an MBT model?

Deleting all test-specific elements to simplify the model.

Checking that the model accurately reflects the system's behavior as described in the requirements.

Adding more details to the model to make it more comprehensive.

Renaming all model elements to shorter names.
