  Question: Why did the industrial designer and the project manager disagree to make the product upgradable?
  Answer:
output: The marketing suggested producing the controller in a way that makes it upgradable like a sim card in the telephone. However, the industrial designer argued that if the controller was to have other functions it would need more buttons and they should design another version instead. Also, the project manager pointed out there would be some risks of making it unusable or less usable.
