Hi All,
I understand that with market sizing questions you're supposed to lay out your structure in a tree first and then do the calculations afterwards. You're supposed to start from the top of the tree (e.g. total market size for balloons in the US) and eventually work down to something like population.
All the tutorials I've seen online are people starting from population, segmenting, and then working their way upwards towards the final answer.
Which is the best way to break down a problem?
For your tree method - I seen you've started from the top, rather than from population. A lot of people I see segment from population and talk their way up. Isn't that the method that is easier to follow?
That's what I'm saying - you start from the top in order not to miss anything and make a structure. Once the structure is done - you start filling the bottom level from population
