Market sizing for number of people at a London tube station

How would you approach to calculate the number of people at a busy tube station at a given hour?

I was thinking of approaching it this way. Let me know your thoughts:

Pick a station, look at the average duration between 2 trains at that station. This will help me calculate the number of trains either arriving at or departing from this station in an hour. I will then see what is the average number of coaches each train has and further look at the occupancy rate of the coaches. Depending on the hour of the day, the trains can be filled at varying capacity. (For the purpose of simplicity, I'll look at standing and seated passengers equally, and include both when looking at capacity). Using this number, I will have an idea of the number of passengers crossing the station at a given hour. If I can determine turnover rate (number of people getting off the train minus those getting on the train) at the station, I will have an idea of the average number of people at the station at a given time. I believe this will again depend on where the station lies - if it is the city centre and the hour of the day is 9-10 am, more people will get off the train than get on. I will then multiply this with 2 as there will be two train directions at any station. I am unable to understand how to estimate this rate.

Could you calculate the proportion of London population who do a morning commute in via tube, then divide by number of stops / in central London?

Bain case: Asian lubricants producer

Solved 154.0k times
Bain case: Asian lubricants producer LubricantsCo, a very successful Asian premium producer of lubricants in their native region, would like to further increase their revenue and profit. The product range ranges from lubricants in the automotive sector (e.g. motor and gear oil) to industrial applications (e.g. fats, heavy-duty oils). According to preliminary examinations, further growth potentials in the Asian core market are rather limited. Thus LubricantsCo would like to investigate options to internationalize in the passenger car business – also outside the premium segment which is given priority. Therefore your consulting firm was instructed to elaborate a market entry strategy for the European market.

Bain Case: Old Winery

Solved 66.3k 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 46.5k 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.
