I am currently applying for new jobs, so I'm planning my exit. And since I am the subject matter expert for an entire tech product, I've been doing my best to create as much documentation as I can to keep them running after I'm gone. But I am not going to tell them my plans because, well, I don't want management to get wind of it since I have not secured an offer yet. Some of my coworkers are great people and have helped me a lot, so I don't want to throw them under the bus.
Obviously, I will give two-weeks notice once I get an offer, and I imagine that will involve training (if they can find someone). But I mean before I even get to that point.
I've created all this documentation, shown it to people, given presentations on it, even suggested they help contribute to it when they have a great new idea. And not just in a passing conversation. I'll mark a comment in the document where they should add it and send it to them, holding their hand as much as possible.
However, no one uses it. Still, everyone comes to me for questions without even trying to use the docs. When I answer the question, I mention, "You can find more about this in the docs as well." And that polite suggestion does not work.
The problem is that this product team is horizontal, so we don't have the same manager. I can't just ask my manager to tell them to use the docs or something. I actually already did that for the one coworker in my same department, but he still didn't contribute (and he's the only one with certain knowledge on his area of the product).
Are there any other strategies I can use to convince people to use and contribute to these docs? Or is it just time to give up so that once I leave, they'll finally realize it's now their problem?
