Hi everyone, just came out of an interview where the case was new product development within the technology sector - case went along the lines of: "The year is 1970 and your client just invented the fax machine. Should they manufacturer and sell it?"
While I applied the business situation framework here and estimated a payback period, I still didn't think I addressed questions around how to project the market for this new technology well enough. Does anyone have any insights into how you would project market demand for a case like this?
