This thinking is taught in MBA programs but does not map onto real businesses. If you're in the ice cube business and you made the profoundly unwise decision to set up vending machines in Inuit communities, you don't recover by laying off x% of both your Alaskan retail and Caribbean Cruise wholesale businesses.
You do if you have multiple primadonnas in middle management that can’t come to an agreement otherwise, and if you can’t sack them due to other factors that require years to resolve.
The real world is thousands of times more complex then ‘MBA programs’ or theoretical examples from people who haven’t been in the hot seat making such serious decisions.
If your management team can't figure out how to do what you're asking, maybe you should be firing them instead. If _no one_ can figure it out, maybe you should be firing you.
