Hi Raj,

I think you're asking how we would coach you to solve these types of problems, is that right?

This is a process optimization/throughput problem. Essentially, whenever we're looking at throughput, we need to figure out which step/s is/are the bottleneck. The bottleneck = where there is less throughput.

Throughput = units/time.

So, in this case, we need to grab potential throughput and multiply it by entitlement to see how many products go through that step/sub-process. Then, within each process, we need to add those sub-process #s together.

The process with the lowest total # (throughput) is your bottleneck and is where we should focus our efforts!

You have three machines. The products goes through each of the three machines.

Each machine can do 3 different tasks, so you need to allocate time for each one.

Overall, the product will need to go through the 9 tasks.

So either you have to optimize the process (allocating different time), or find the bottleneck, or the max capacity of the process (which depends on the bottleneck). The question of course, depends on the case and questions being asked.

Hi there,

Not sure exactly you're after but there's a way to approach these types of questions in conjunction with big tables and lots of numbers.

The key is to create new numbers, but fewer, that collectively tell the story. The question is not testing your engineering skills but your ability to synthesize insights using quant.

Is this going in the right direction? Let me know - happy to elaborate more!

Best,

Moritz

As before, Just to add to what others are saying, if this is from a preplounge case, you should point us to it so we can have a look.

Hi Raj,

It is basically impossible to describe in a few sentences how I would be able to help you - especially since I doubt that the only weak spot you might have is understanding this specific system.

If you would like a more detailed discussion on how to address your specific situation, please don't hesitate to contact me directly.

Best,

Hagen
