Hi there,

Got to say the question is very confusing and a few concepts are mixed up.

"Divide in value chain" refers to the gap in value chain. To identify the divide in value chain, you need to first map out the value chain, what are all the different steps/stages in the end-to-end process. E.g. Procurement -> Supply Chain Planning -> Manufacturing -> Distribution -> In-store sales -> After sales service. An example of "divide" here could be the procurement function and the supply planning function is not working in sync, e.g. supply planning requires 100 tons of materials, but procurement only purchases 80 tons.

On the car accident example quoted here, tbh it is not clear to me how it is a value chain problem?

Best,

1 and 2 are very different concepts. I think you're confused because they're both represented by "rates" but one is counting "in minus out" and the other is "how long" from the point of putting something in to it coming out - very different.

In regards to your denominator question (which is what I think you're asking for), like any case question, you should frame it already with a hypothesis in mind. So, what do you think is the denominator of car accidents? Say "I'm thinking the denominator is x" or "I'm going to go with the view that the denominator is x", and then confirm that that logic is correct.

Hi,

I think you put in one place the value chain approach and the math approach:

• Value chain - is going through the key steps of the value creation / process
• Math - you list the mathematical parts: Birth rate, death rate, migration

You can use math to structure the process even based on common sense. Value chain - you can either ask the interviewer what is the process or you can build based on common sense as well

Hello!

This applies particularly to the value chain cases. Hints to identify those: cases involving supply chain and logistics, cases with operational bottlenecks, etc.

For those, totally agree with you that it´s key to identfy and even draw in a piece of people asap in the case the whole value chain, not only including product flow but also influencing agents (e.g., for the go-to-market of an specific drug, don´t only include the flow factory > distributors > pharmacy > patients but also dotted lines with insurance companies and doctors.

For this, make questions such as "do you have information about the different agents in the value chain?", etc.

Hope it helps!

Cheers,
