My advice or, better yet, what I’ve learned, is that if you need to know which business process to improve first, start with anything that involves “cutting and pasting.”
Like my boss says, “one offs are invariably #($)# up.”
“One offs” usually involve a process of cutting and pasting large rows of data from one source to another.
Try to focus on the goal of the analysis that requires the "cutting and pasting” and deliver that to the user. The more successful you are at providing these types of solutions, the more “buy in” you’ll gain.
Eventually you’ll start seeing emails with solid business goals and defined processes as part of the requests for help.
