How to structuring the market sizing case?

Taking an example, "Children vaccine" case, I wonder how we structure the case, whether it use the same structure (MECE or issue tree) like other types of case or we use the different structure for market sizing case.

Hi,

First of all, market sizing can be either a part of the case or a standalone case.

Secondly, It's less about different types of the problems but rather about the tools that you use:

1) First of all, there are 2 ways to structure market sizing:

  • Formula - basically a math formula to come up with a solution. The problem with the formula is that it is easy to forget something or get lost.
  • Tree - same as with regular cases you build a tree. A very simple example: you need to calculate the number of dogs on manhattan. A number of dogs = share of households having a dog * # of households. # of households = population / average household size. In the end, you'll have a pyramid where you have to fill the numbers on the base of the pyramid. This approach is much easier and help you track all the numbers

2) You should learn the key market sizing techniques:

  • Making assumptions based on personal experiences (Use the example of your house where out of 100 apt-s 10 have dogs)
  • Adjusting numbers (NY is a busy city thus fewer people have dogs)
  • Sanity check - try to apply your calculations to the real environment
  • etc.

3) You should learn the key tools:

  • Using age even age split (suppose life expectancy is 80 years. Assuming even age split we have 4 mln people in US of each age)
  • Using 80/20 split (suppose 20% people earn 80% wealth and the average salary is xx...)
  • Using approximations (Length of NY-SF flight and plane speed to calculate US length)
  • etc.

4) Learn key numbers: populations, gas price, gas consumption, Boeing speed and nmber of seats, average salary, # of gates in the airport, GDP growth rate, inflation, etc.

5) Practice 10-15 cases and you'll be fine. Almost all casebooks have good market sizing examples and the solutions

Feel free to PM for clarifications

Good Luck!

Bain Case: Old Winery

Solved 45.7k 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 29.6k 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.
