Funny thing is the tools are dumb in that they can't actually predict the long-term and mid-term effects of bringing on such a change. And this is a text-book case of that because they have reverted back to independent entities. Like for instance knowledge lost. How do you account for that? Loss of morale? How do you account for that. Communication problems, etc. etc. etc. All these things can be a competitive advantages or disadvantages for a corporation. They can potentially make or break a company.
In fact someone should create an AI called MBA AI to do this sort of shit and make a killing doing it. Just replace idiot MBAs with their dumb tools with an AI. It should be simple enough to automate to generate cost saving estimates and so on. Without actually being able to predict the actual outcome in any meaningful way.
I will finally add that in the end Jurassic Park was caused by an underpaid IT contractor.
