Altough I'm able to solve most of the guessestimate questions (brainteaser and market sizing in particular), sometimes I struggle to approach and then solve with the most difficult ones. Therefore, I wonder whether my approach is not that general that I can "size" for every guessestimate case.
So I ask you:
- Do you have a general approach/framework you use to solve any kind of guessestimate, brainteaser, market sizing ecc. like any other business case framework that, a part from details, you can always use once you understand the case?
- If not, how do you handle the most difficult and strange guessestimate? It may be a matter of practice?
