Market Sizing Questions - No. of Restaurants in Paris, can someone check my approach?

1. % of people in Paris going out to eat for lunch/dinner, and % who go to restaurants as compared to takeaway/supermarkets/bakeries etc.

population paris -> 3 Mio (wild guess) % eat outside per day, 30% (900.000), percent of those who actually go to a restaurant 50% (450.000)

tourists -> 300.000 in the city on a given day (1/10 of population) % eat outside 70% (210.000), % eat in restaurants 80% (approx. 170.000)

2. Overall target market: 620.000 people per day - define peak hours

Peak hours: 11:00 - 14:00 for lunch and 17:00-20.00 for dinner

concentration: 50% / 50% so 310.000 each

3. Avg. Number per group

Important to calculate the occupancy rate per table. Say on average, 3 people go to a restaurant together, Would mean there is a need for approx. 100k tables in the peak hours.

4. Avg. Time spend in restaurants

Say 1 hour, so a restaurant can serve 3 groups during peak hours

5. Avg. Tables per restaurant

Say a restaurant has on average 10 tables. This would mean during the peak hours 30 groups can be served which would mean 90 persons per restaurant in peak hour and 180 persons per day.

6. No of Restaurants

Take the 600.000 people from the beginning and divide by approximately 200 which would equal 3000 people per day

Sanity check: 3 Mio people and 3000 restaurants would equal a 1000 people per restaurant which would be quite high. Thus I would double my estimate to at least 6000 - which would indicate 500 people on every restaurant. This would be in line with my experience of smaller towns and even villages with around 20 restaurants per 10.000 people.

I would add a few points to your calculation to make it more robust:

  • Distribution of people that go for lunch vs dinner might not be equally split which increases the number of restaurants, as most are empty for lunch
  • It seems you're implicitly assuming that occupancy is 100% at peak hours for all restaurants,so you're calculating the minimum number of restaurants you need to serve the demand.

Other than that, I think your approach is solid and makes sense to me.

Hi,

You can also calculate from the supply side:

  • Calculate the ovarall area of the city
  • Split the city into tourist center, center,surbubs
  • Assume the number of blocks in each
  • Assume number of restaurats per block
  • Assume work hours, occupancy, av time

Honestly, it's pretty good! nothing to add from the other coaches.

The most important thing here is you split up things logically (i.e. not unecessarily) and made fairly reasonable assumptions.

Bain Case: Old Winery

Solved 68.5k 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 48.4k 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.
