   A team uses a requirements management tool and an MBT modeling tool that are not integrated. A requirement changes frequently, and the team manually updates the model each time. This has led to inconsistencies. What is the most effective way to improve consistency?

   • AEstablish a formal change-control process that requires model updates to be reviewed alongside requirement changes.
   • BStop updating the model and rely on the requirements document.
   • CRegenerate the model from scratch after every requirement change.
   • DAsk the developer to update the model whenever they change the code.

   • BData dictionaries that define field types
   • CWorkflow steps that describe the sequence of activities

   An insurance company is modeling its claim-approval workflow. The business process has an approval step that is skipped for claims under $500. The team wants to ensure the MBT model reflects this rule. Which approach best maps this process information to the model?

   • APlace the approval step in the model but mark it as 'optional' without a condition.
   • BAdd a decision node in the model that branches on the claim amount, with the approval step on one branch only.
   • CDocument the rule only in the requirements document and not in the model.
   • DCreate two separate models, one for claims under $500 and one for claims over $500.

   A team has a large MBT model with over 500 model elements and 200 requirements. A new requirement REQ-300 is added that affects the behavior of an existing state. The team wants to know which test cases will be affected. What is the most efficient approach?

   • AUse the traceability links to trace from REQ-300 to the model element, then to the generated test cases.
   • BManually review all 500 model elements to find the affected state.
   • CRegenerate all test cases and compare the outputs.
   • DAsk the developer to identify the affected code and then find the tests.
