I just left a $45B company that has many of the same issues you mention. There were efforts around consolidating competing technologies and vendors as well as a very large "digital transformation" effort which I was directly a part of. None of the efforts went very well for a variety of reasons including reorgs, two competing technology organizations, hard economic times, etc. Another underlying issue I saw was lack of accountability and communication. "Technical debt factory" is a great way to phrase it.

Ultimately, leadership has to make tough decisions cut costs while not impacting the company's continued growth.
