   A team is planning to use MBT for a system that will be developed incrementally. They want to minimize the cost of model maintenance. What is the best practice?

   • AAvoid updating the model until the system is complete
   • BCreate a complete model of the entire system before development starts
   • CDevelop the model incrementally alongside the system
   • DUse a tool that automatically generates models from code

   A team is adopting MBT for a system that is already in production. They have a limited budget and need to show value quickly. The system has a high number of regression tests that are run manually. What is the most cost-effective strategy?

   • AModel the entire system to ensure complete coverage
   • BInvest in training for all testers before starting any modeling
   • CModel the most critical workflows and generate regression tests to replace manual ones
   • DPurchase the most advanced MBT tool to ensure success

   A company has a mature manual testing process for a product that changes frequently. They are evaluating MBT to reduce regression testing effort. The team has strong domain knowledge but no modeling experience. Which cost-benefit trade-off is most favorable for adopting MBT?

   • AHigh tool licensing cost that is justified by eliminating all manual testing
   • BLow initial modeling cost because the team already knows the domain
   • CLow maintenance cost because the model only needs updating when the requirements change
   • DHigh initial modeling cost offset by reduced effort in future regression cycles

   How do the cost factors of MBT typically interact to affect the overall cost-benefit?

   • AModel creation costs are negligible, so the main cost is always test execution
   • BTool costs are always the largest expense, making other cost factors irrelevant
   • CTraining costs are the only factor that determines whether MBT is cost-effective
   • DHigh initial model creation costs are often offset by reduced test maintenance and execution effort over time

   In a project with a tight budget, which cost factor would most likely lead to a decision to use MBT only for a subset of the system?

   • AHigh model creation costs for the entire system
   • BHigh costs for test execution tools
   • CLow training costs for the testing team
   • DLow maintenance costs for models
