90% of the companies do not know how to manage software. They got weird dogmas, no KPIs, no ability to measure performance or debug problems. This is why they got external consultants and cloud vendors. What is really funny how they think internally about these issues. If Netflix and Amazon was publishing efficiency numbers and we were able to compare with the bottom 95% of tech users people would be shocked. The difference between the numbers I am aware of (number of computers / engineer for example) is 100x.
