At one job we had a digital form for new user requests. This existed for auditing purposes, but it also helped to collect all the necessary information for the change. I was always impressed at how people managed to fill it out wrong every single time.

For example, I would get a request to update someone's name and they would fail to include the former name or the new name or even enter their OWN name for one of the fields.

What I learned is no system is idiot proof, no form will ever be filled out perfectly, and everything will need manual intervention at some point.
