Hi, I have some questions regarding this case:
1. This case is only focusing on the solution of increasing profitability. I'm confused about the sentence "The cost side is more important to better understand the profitability issue." Indeed we know that the house in Munich has a slightly higher margin compared to those in Berlin. But how should I decide whether it is more important to discuss ways to increase revenue first, or ways to reduce cost?
2. The recommendations don't look solid. It seems to me that these are solutions that are being "brainstormed". For instance, one recommendation is increasing new revenue stream. How do I know whether this would increase the profitability, since client's main concern is about profit?
3. In a real interview scenario, would these kind of recommendation seem "solid" enough?
