Hang on... That could also work in your favour. In fact, I am almost certain that there is some kind of system around:
It may not be documented, and people may not be fully aware of it, but they must have ironed out reasonable ways to solve their tasks over the years. That is your starting point, so beware of reinventing the wheel before you know that it is not already there. When you start figuring your processes out, that system will emerge from the shadows, and as previously suggested, a gap analysis will show what else you need. <snip>
