I have a new project at work that involves foreseeing how customers might use a software and recommend to our IT experts / programmers how this software can be improved, test for issues, etc. by different deadlines set by their department. (I have been assigned to this as I have extensively used a similar software in my previous work at the company, was the top performer in the department and manage my staff of users of that software; though I don't know how software is created)
I don't know whether it is due to my recent issues with focusing or whether I simply am unable to do this regardless - but it appears that I am not doing a good job on this because the IT guys later find more program errors than I do, and for the past few weeks my boss has been admonishing me all the time:"See you should have found this", "This is what you were supposed to find", "You need to check more thoroughly" etc.
I am just plain confused because, obviously, I didn't know that a customer could do a process I didn't know about, i.e. it is actually not written in stone what all the different scenarios are (they could potentially go beyond the previous software I used) - but they would count that as an error as well!
So there are two possibilities: I am unable to forecast all scenarios either because I have an irritating health issue that hinders my focus, or because I am not learning this.
What should I do in the second case, i.e. I don't understand exactly what I need to do, no matter how many times my boss admonishes me?
