Yes–it is absolutely the thing you need to do (document and create processes). But there are limits to this. For example, with my WordPress plugins there are integrations we support and those 3rd party plugins have limits or quirks I can’t fix or create a process for. Often, I’ll create an FAQ article for it–but I still have to answer that question 3x a week (my support volume is about 1000 emails/month, more or less–anything I can do to reduce it is helpful)
That’s an example of what I meant above. It’s process-documented and there’s no more value in my participating in the conversation anymore. Create the FAQ, tell someone when to answer the question with it, and boom–move on.
