I have been using the LOMS recently and got confused by the logic proposed when tackling profitability problems.
Generally, VC (Victor Cheng) is totally fine with candidates concluding that if revenues are down and costs are down, then we actually have a revenue (growth) problem in order to turn profits back to profitability. So candidates directly tackle the revenue side regardless of the profitability segmentation i.e. there might be segments that are more profitable than others.
This way of tackling profitability problems is also suggested on the preplounge boot camp and I have been using it successfully. However, in the LOMS Case 4 candidates concluding that the profit problem is a revenue problem (due to decrease in revenue and decrease in costs) is marked as a mistake. According to VC, the company has different business segments and one would tackle first which businesses are profitable and which are not. He also suggests that focusing on the one with the highest profits is the solution instead of turning around the one with the lowest (most negative) profit.
So, I'm quite confused by how to proceed further. Concluding directly that we are dealing with a revenue (not profitability) problem if revenues are down while costs are down as well seems to be a mistake. However, in the cases 2 and 3 candidates solved it in that way and it was corect according to VC. The only difference: Cases 2,3 deal with a company with 1 business segment but various products, while Case 4 has 3 different business lines. In my opinion if we segment into product/business lines etc. does not really matter.
Help is highly appreciated here! Especially from people with LOMS knowledge. Sorry for this very specific question.
