   Which cost factor interaction is most likely to improve the cost-benefit of MBT in a long-lived system?

   • AHigher initial modeling effort reduces the need for frequent test case updates as requirements change
   • BIncreased model maintenance costs are offset by reduced need for system changes
   • CHigher tool license costs are offset by reduced need for any testing expertise
   • DLower training costs lead to higher model quality, which always reduces overall costs

   A team is comparing the cost of maintaining a set of manual test scripts versus maintaining a model for MBT. The system has a high rate of change. Which statement best reflects the cost trade-off?

   • ABoth have the same maintenance cost because they both require updating test logic
   • BManual test scripts are cheaper to maintain because they are written in a familiar language
   • CManual test scripts are cheaper because they do not require a tool
   • DModel maintenance is cheaper because a single change in the model can update many generated tests
