Market sizing case questions

Hi there,

The answer depends a bit on the type of market sizing case.

1. Short market sizing within the context of another case

• You can do this quick and dirty by just adding a % on top of your estimation
• “I would say for every private TV, there is at least one public TV, for instance in pubs, hospitals, etc. Hence, I would like to double my initial estimate.”
• Be prepared to defend your choice and increase or decrease the % if pressed

2. Long market sizing standalone case

• You need to identify one area, then extrapolate for the country as a whole
• In that area think of segments that have TVs, list every area you can think of, and then make assumptions, essentially exactly as you mentioned in your answer
• The focus should be on the way you think and defend your assumptions, not on being 100% accurate
• Interviewers want to see a directionally correct answer that is well-defended and interpreted

The funny thing is that short and efficient market sizing usually yields the same “accurate” results as longer and more complex approaches. Try it for yourself and see where you end up. :-)

Hi there, 

If this is still relevant, happy to share a case book with market sizing questions that could provide some extra practice and guidance.

The simple answer is - for commercial use a multiple of consumer. So if consumer is 100 TVs then commercial should be a multiple (either less than 1 or greater than 1) of 100 depending on your rationale - for example if there are more use cases for TVs, if you need more than one TV per person etc. Usually its a percentage of consumer but it really depends on what you are looking at.
