How much should we, as ID's, know?
I'm currently working on a class for Tableau and need to make some changes to our Advanced Tableau course. I need to add an exercise and, since I designed the course from scratch, I'm the SME. No problem, right?
Well, it is a problem because, while I designed the course, I don't "know" it. The Tableau learning community is incredible, but I just spent literally hours on developing another exercise and found the solution/process doesn't work! (And, honestly, that's what I get when I use an article from 2014; I'm assuming upgrades to Tableau have deprecated the solution in the article).
Anyway, while I know this isn't a question about SL specifically, how much do we, as ID's, need to "know" to get good stuff out there? I apologize if I'm being insanely ambiguous or generic (and I'm sure it depends on the project), but when you're creating something, how far into learning and understanding the concept, software, etc. do you get before you stand back and say, "Whoa. I'm not the SME here; I need some help to make sense of this." Does that make you look incapable as the ID? How often do you come across individuals who think ID=SME and just a couple books, some research and BOOM! you'll be able to create magic that solves all the client's problems? And if you do come across those types of situations, how do you handle that?
Thanks for any ideas, suggestions, comments, etc.!
