I am preparing for am interview next week and I would much appreciate if anyone could share his thoughts on this question! Also, how would the answer change if the timeframe was in a day?

Many thanks

Hi there,

You'll really get the best out of this exercise if you try it yourself. Why don't you post what you're thinking and we can help?

Hint: Do you think this makes more sense top-down or bottom up?

General Tips

Remember that there's rarely a "best" answer with market sizing. What's important is that you break down the problem the way it makes sense to you. Importantly, break it down so that the assumptions you make are the ones you're most comfortable in.

For example, do you know all the major brands? Great go with that. Do you understand all the segments of that country's population (either age or wealth or job breakdown)? Go with that. Do you know the total market size of a similar industry? Then break it down that way.

If it will be done bottom up, you think we should start with what?

Here's how i would do it Equation: # of births/Day X Avg Duration a Bed is needed # of births in US is slightly over 1% of pop so 4 M new kids born year or 4M/400 = 10K births per day Now now all births are same so i would break down into normal delivery and c section. I would assume a 60:40 so 6K normal briths and 4K c section That means 6,000 X 3 Days (avg bed needed for normal) + 4,000 X 5 Days (Avg bed needed for c section) 18K + 20K = 38K making it 40K. Let me know your thoughts. I feel I am missing something.

Hey there!

Why wouldn't you write your solution first? This way you would practice and test your skills. We will give you extensive feedback then!

Hope to see your approach!

Hi Gaurav, thanks a lot for your comment! I would approach it as follows: I would assume that the # of hospital beds required for pregnant women is equal to the # of babies born each year. Assuming that (i) the population is evenly distributed by age (ii) the average life expectancy is 80 years and (iii) US population is 300 M people, the # of newborns per year(= to the # of hospital beds necessary for pregnant women) is 300M/80years = 3.75 M. Do you think it makes sense? Many thanks, M

That is incorrect and so is my answer posted below. Why would you need 3/75 Million beds. Not everyone is born on the same day.

Here's how i would do it

Equation: # of births/Day X Avg Duration a Bed is needed

# of births in US is slightly over 1% of pop so 4 M new kids born year or 4M/400 = 10K births per day

Now now all births are same so i would break down into normal delivery and c section. I would assume a 60:40 so 6K normal briths and 4K c section

That means

6,000 X 3 Days (avg bed needed for normal) + 4,000 X 5 Days (Avg bed needed for c section)

18K + 20K = 38K making it 40K

Experts, please weigh in

Good breakdown, only usually bed is needed for a day after normal birth, and 3-4 days after c-section
