Every business experiences document workflows. They are the way information moves between employees internally and suppliers and clients externally. They have a direct impact on business revenues and results.
They are unseen since they are not documented or understood very well. The information flows in a business are simply seen as a part of doing everyday work. Sometimes individual components of these flows are looked at as a way to administer costs and potentially to save money. 
Consider printing costs as an example. Many businesses have started to look at the amount of paper they produce and the cost of the tools used to do so.

This is an excellent way to drive unneeded costs out of a business if done right. read more here from my friends at Leppert!
