I’m struggling with how to start a market sizing case (and so not a market sizing question within a wider case):
- Do I have to start directly to brainstorm/find the right drivers to estimate the market size and then ask questions/information during case about the drivers you found?
- Do I have to start first with preliminary questions about the market and then keep going on with brainstorming and cracking the case? If yes, what kind of questions since you do not have precise information?
Thanks a lot.
