While your first instinct should always be to solve any problem you are confronted with, there are a class of issues for which the solution might be out of reach. Perhaps the costs outweigh the benefits, or the steps to resolution are overly complex, risky or will take too long to implement.
In these situations, focusing on mitigating the harm being done might be the right solution (at least temporarily). Yes, “making things less worse” isn’t traditionally considered a business triumph. However, there are cases where it makes sense.

I couldn’t agree more. It reminds me a bit of the saying “the remedy is worse than the disease” (Francis Bacon). At the end of the day, not all problems have solutions and in the words of Frank Sinatra “that’s life”.
