E.g. addressing a decline in profitability.
The standard issue tree would include revenue and cost, but where would you include an overview of the market/competition/etc.? I usually make a side note but that doesn't make it very MECE - is there a different type of issue tree to use?
I feel like this is such a simple question but can't figure out how to structure this properly.
If I understood your approach correctly, wouldn't the interviewer think that the initial framework is not complete? In other words, we don't show the interviewer a complete framework at the beginning. This is more efficient as you said, but it does not show an end-to-end solution to the problem at the beginning of the case.
