Case Prompt

Your client is a medical device company. Recently they acquired a company that produces heart stents. The CEO feels that the previous management had not maximized the market potential for these heart stents.

  • There are three distribution options
    • Use our current proprietary sales force
    • Create a distinct sales force for heart stents
    • Have medical distributors distribute our product
  • Our current sales force is comprised primarily of pharmaceutical style sales-reps with little or no medical training
  • Other heart stent manufacturers use distributors
  • If we were to build a new, distinct sales force it would be comprised of surgeons who would do a heart surgery alongside a cardiologist and show them how to use the heart stents
  • It is not a problem to hire qualified sales reps for a new sales force

He has asked you to determine what the potential market size is as well as determine the best method to distribute the product.
