Kevin and Alice discuss how small changes in the incoming box volume will impact the cash-flow analyses. This is how sensitivity analyses are tested for in a case.
Alice completes the qualitative portion of the sensitivity analyses by discussing what would be needed for the rate of input to drop from 10MM boxes to zero.
Alice effectively wraps up the case because she is able to immediately recall the key insights from the case, without pausing, and review her notes while speaking.
This case is based on a true story and teaches an important analytic skill in cases around understanding the different forces, which may impact similar areas of a business.
