If you have done one or both of these cases, would you mind setting up a brief chat to go over some of the math? Or, if you can leave a comment, my main question on the Helicopter case is this (and it wasn't answered in the video):

Why should the interviewee only multiply 1250 * 10 for the Canadian and UK markets (for the fee to take these into America). They are making a lot more helicopters than this, right? And, if they are making more - who is buying the rest? Why are we making so many in the UK and (potential Canada)? (If you watch the youtube, he actually lets the guy multiply some totally insane numbers that are completely wrong.)

For the Lube case, The website says:

In Germany each of the approximately 40 million households has on average one car. This corresponds to a stock of approximately 40 million cars and accordingly a density of 500 cars per 1.000 inhabitants (population: 80 m.).

This is random as hell. Is there any rationale? Are we really supposed to know there are 40m households in Germany and each has 1 car?

Also, why on earth would you set up a "test market" in Turkey without analyzing the market with market research first? Turkey tells you nothing about France - or 20 other Euopean countries. This should've been done analytically looking at data for each market, not setting up a test market...like cereal at a grocery or something. I think the whole approach is wrong, but if you can convince me you're right - I'd love to hear.

Let me try to take a stab at the lube case.

1. While it is rather random to use cars per 1,000 inhabitants as your metric, it is useful because that is the metric that the case has already established for Russia and Turkey. Table 1 shows information on Turkey, Russia and Germany, but omits the car density for Germany. Thus, it then becomes an exercise to try to estimate that missing information. Some clarifying questions are needed to figure out that "car density" means "# of cars per 1000 inhabitants". Once you know that is what you are solving, then it is just an estimation exercise. In this case, having some sense of the German population (80M) would help, but if you don't, it is fine. You could just say, I am not too familiar with the population of Germany, I know that the US is about 300M, would it be fair to assume that Germany is about half the size of the US?" Your interviewer would probably then just give you the accurate information, not penalizing you for not knowing it but appreciating that you understand how to find the info. in this case 40M households and 1 care per household is the information the case suggests, in real life you could come up with any reasonable number and it would make sense, but your interviewer would probably then say something like, "that makes sense, but for this case let's just assume there are 40M households in Germany and on average 1 car per household". It doesn't make it necessarily true, just a consistent number for both you and the interviewer to ensure that you both can reach the same end conclusion.

So in the end, yea it is random, but that comfort with ambiguity is part of what they are testing.

2. Also, in choosing a pilot in Turkey. The case is intended to focus on 3 countries in particular that the company has already identified as preferred countries for expansion (Turkey, Germany and Russia). I think that is part of the clarification process, asking if there is any specific area or countries in Europe that they are considering expanding into. Once you get that information, it becomes clear that you are really only looking at 3 countries. And then you narrow it down even more by looking at the pros and cons of each of those countries. This leads you to focus on Turkey.

3. A pilot program is suggested in this case because data can only tell you so much, at some point you have to actually do it. And in this case it is best to do it on a small scale to ensure that it works. Yes data is essential, and that could be part of the risk/risk mitigation in the final recommendation, but in the end, consultants (especially Bain, as this is a Bain case) are partial to action. So the recommendation (especially for Bain) is generally preferred to be rooted in an actionable recommendation while considering the risks involved and next steps to address them.

Something like, "I would recommend the client gets started with a pilot program in Turkey for these three reasons, 1. blah, 2. blah, 3. blah., There are a few risks I would need to iron out first; primarily how valid the growth, profitability and customer demand projections we have are. In order to address this I would want to dive more analytically into the data and get a bit more market research. But with that said, I believe that a pilot program in Turkey is the best course of action based on the information available right now."

That's the best I can quickly think of addressing the issues you mentioned. It's probably important to mention that the solution that is recommended is by no means the only answer to the problem. If you had a different conclusion, it very well could be just as valid.

John - Awesome answer. Thank you so much for taking the time to type all of that out. I just re-read my question and I sound crazy. ha. I get annoyed when I get cases wrong sometimes. So, essentially the German cars is a mini-estimation case with a couple of facts provided, and a couple that you need to feel comfotable asking (or knowing Germany has 80m people)...but that one fact (the 1000 metric) because I felt that Turkey and Russia were too different from Germany. That could've easily been validated by the interviewer, "is it ok if I use the same density metric?"

Interesting take on the "action plan" vs. my "analytical plan". That makes sense...and again, maybe is in the case notes or an actual interviewer interaction - saying "is the goal to start selling right away or did the client simply want a breakdown of these countries, etc..." then move to the activities in opening Turkey.
