Have you ever been asked at work, "Why do different people do things differently?" It's the same job, but Team A does it this way, Team B does it that way... The quality of the output varies, and handoffs are complicated.

One company I worked with was really bad, because everything from how they dealt with customers to how they wrote reports was tailored to their personal style, so there was a lot of variation in quality. But once they started to standardize things, it was a completely different organization.
