Many companies that have made themselves dependent on IBM-equipment (and in doing so have sold their soul to the devil) will collapse under the sheer weight of the unmastered complexity of their data processing systems.
Interestingly, this still applies except s/IBM-equipment/Microsoft software/. Further, I have not seen any companies collapse due to the unmastered complexity (IBM or Microsoft), but I do see a lot of people that have no clue what they are doing, they just do the same steps over and over because someone in the dim dark past discovered that those steps formed a path through the maze of complexity. The Office equivalent of "Up Up Down Down Left Right Left Right A B Select Start".
I'm pretty sure entire companies don't collapse, but projects are canceled and companies are limited in what they can do by relying on overly-complex solutions. I know that from experience.
Of course, that's one thing that can give a startup an advantage against a giant, provided the startup doesn't fall into the same trap.
