“A small error in the former will produce an enormous error in the latter.”

Henri Poincare

A formalized workflow will undoubtedly reduce the number of errors that occur.  By programmatically performing tasks, consistent operations can be achieved and the business can scale.  Once a process has tested, it can largely be trusted to perform this series of tasks with each execution.

Customers, both internal and external appreciate when things work as advertised. When they can trust the system, then they can add value elsewhere. Conversely, when errors are prevalent, users spend time double checking results, or worse, accepting bad data and using that in their decision making.
