A team maintains an MBT model for a CRM system. After a sprint, requirement REQ-201 is changed to remove the 'export to CSV' feature. The model contains a state 'ExportMenu' and a transition 'ExportCSV'. What should the team do to maintain consistency?

Change the 'ExportCSV' transition to a different export format.

Keep the model unchanged and note that the feature is deprecated.

Remove the 'ExportCSV' transition and the 'ExportMenu' state if it is no longer reachable.

Update the requirement to keep the CSV feature because the model already has it.

A modeler maps a business rule 'the system shall send a confirmation email' to a model transition. The rule is derived from a stakeholder interview, not from a formal requirement document. What should the modeler do?

Document the source of the rule as a stakeholder interview in the traceability record.

Ask the stakeholder to write a formal requirement before modeling.

Add the rule to the model without any documentation.

Do not include the rule in the model because it is not in the requirements document.

A team discovers that a model element was updated to reflect a new requirement, but the corresponding requirement was not updated. The team is now unsure whether the model or the requirement is the source of truth. What is the best way to resolve this?

Assume the requirement is correct and revert the model.

Assume the model is correct because it was updated more recently.

Delete the requirement and keep the model as the source of truth.

Convene a review with the stakeholders to determine the intended behavior and update both the requirement and the model.

When a requirement changes, what must be done to maintain consistency between the requirement and the MBT model?

Freeze the model and only change the requirement

Update the model to reflect the change and update the traceability links

Delete the affected model elements and recreate them from scratch

Only update the traceability matrix without changing the model

A team is creating an MBT model for a new feature. Requirement REQ-10 is linked to a model element 'Login'. The team later realizes that REQ-10 also covers 'Logout', which is a separate model element. What should the team do to maintain traceability?

Create a new requirement REQ-11 for 'Logout' and link it to the 'Logout' element.

Remove the link from REQ-10 to 'Login' and link it only to 'Logout'.

Create a link from REQ-10 to both the 'Login' and 'Logout' model elements.

Keep the link only to 'Login' because that was the original mapping.
