Ciao Guillaume

I found a lot of good, profit / loss cases in the LBS case books. Especially in the one of 2012. Let me know if you have them. If not, I can share.

Cheers,

Andy

Hi,

There are several types of operational cases that you may have:

1) Operational math problems. (e.g. Should we increase the speed of the elevator or just buy a second one? How should we reduce the queues? How should we increase the output of a factory?).

Structuring:

  • Usually, you have to look at the process (value chain). Even the most complicated systems have the inflows and outflows

The key concepts that you have to learn:

  • Capacity and utilization (both machine and people)
  • Cycle time, Throughput time, Little's Law
  • How the does lowest cycle time influence the production? (Lead time = cycle time of the slowest process)
  • How can we mitigate the bottlenecks with low cycle time? (Buffer, Parallel process, speeding up)

2) Cost cutting cases

Structuring:

  • What is the cost composition and what are the biggest costs
  • Benchmarking of the biggest costs to find the improvement potential
  • Process improvements to meet the benchmarks
  • Costs and benefits of the proposed initiatives

The key concepts that you have to learn:

  • Internal / external benchmarking
  • Idle time
  • Core processes (usually are optimized) and the supporting processes (usually are cut)
  • Math structures (Frequency of operations * time per operation)
  • Other useful structures (e.g. people - process - technology)

Feel free to reach me for further help with these cases.

Best
