# How to estimate the # of business in china?

Hello everyone!

What do you think of this approach?

• To estimate the # of business that buy firewors I would find # people of working age on China that work on firms / Average # people per firm.
• To estimate the number of people of working age in China I would start by Chinese population x % in working age that work in firms.
• For that I would start segmenting 1b population into population on working age 52.5% (Population between 18-60 years) = 525 m. Then I would segment this by % Employed ( 90%) and % Unemployed (10%), then I would segment the %Employed into % Working by firms (80%) and % Self employed (10%), this would give me a 380m.
• To estimate the Average # people per business I would do the following segmentation: - 20 employes for 90% of firms - 50 employes for 9% of firms - 200 employes for 1% of firms This gives me 18. So I get 21.1 m

Thank you everyone.

Hey Floyd!

First, thanks for being so active on the Q&A!

Now, I can't help but note that this is like your 10th Market Sizing post.

Furthermore, your approach is always not quite right. You do all kinds of assumptions/step that really just beat around the bush, then you jump to a random estimation. For example, points 1-3 above do nothing for you! Point 4 is the entire point of the case...and you just put a finger in the air and guess. THIS is where you have to start the market sizing (i.e. break things down to figure out what this number could be).

You're really missing the point of market sizing...I highly high advise a coaching session to run home how you need to think about/approach market sizing.

Hello Ian, Thank you for your answer. I'm wondering, should I segment even more to get the # of business that sells fireworks? — Floyd on Mar 06, 2021

Hello Floyd!

Love that you are so active here with your market estimations :)

For this particular example: I would actually advise the more "conventional" ones. This, without further gudance, is more complicated than what you would usually find in an MBB interview.

Hope it helps!

Cheers,

Clara

### Bain Case: Old Winery

Solved 68.3k times
Bain Case: Old Winery You have inherited the “Old Winery” from your grandfather, a winery which has been family owned for five generations and can be dated back to the 16th century. Half of the eleven hectares are used to grow white grapes, the other half to grow red grapes. They are grown in the conventional way, i.e. they are not organically farmed and certified. The vine stocks are in a good condition regarding age and care. Overall, only ¼ of the harvest is made into wine by the winery itself; the rest is sold. Your grandfather never wanted to change the image of the winery and left the managerial and administrative task to a young and energetic wine-maker. Due to the not so well-known brand , the demand for the “Old Winery” wine is currently rather low. You do not intent to run the winery operatively, given your limited knowledge of wine making, but find the idea of owning a winery exciting. Your plan is to give the winery some fresh impetus.

### Roland Berger Case: Onlinestar

Solved 48.2k times
Roland Berger Case: Onlinestar Onlinestar, an online retailer of furniture and garden products (core business), has grown significantly in recent years as a result of an expansion of its product portfolio. The company mainly imports goods from Chinese manufacturers but also operates its own production of cat lavatories (special business) in Eastern Europe. The company sells its goods via Amazon and ebay, and recently via an online shop on its website. Despite this development, the financial ratios have deteriorated in recent years. In particular, gross profit margin decreased significantly. Combined with a significant increase in shipping costs, this led to a negative result for the first time in the recently ended fiscal year and a resulting strained financial situation. Against the background of expected stagnating sales for the current financial year, short-term action is required. The board of Onlinestar asks you for an analysis of the reasons for the negative result as well as a derived recommendation for action. As a consultant, you should bring in your knowledge in online trading and develop solutions. In addition, the management board would like to receive a sales and gross profit plan from you for the current financial year.
