Defining procedures is difficult, but if you want to successfully train new users, it’s something that needs to be done.
Three and a half years ago, I experienced this firsthand. I began working for an organization, and was assigned to replace an employee who was leaving. I remember sitting down with them so they could show me how to do their job. But after an hour of chatting, I still didn’t know what I would to be doing - I didn’t get a list of tasks, nor did I receive any standard operating procedures.
I was going to have to learn through trial and error.
