You kind of have to be a rebel to get that knowledge. Most teams don’t want developers talking to customers or spending time understanding the domain beyond their next ticket, and even in that case they’ll get a product managers distilled version. If the industry has courses/exams and a path of its own that’s helpful so you can get the knowledge that way.
I don't think that is the case, or atleast that has not been my experience. Most teams would be happy if you do these, but not affecting the next deliverable. So if you are willing or can spend extra hours that becomes manageable, but one can't always be in a position to spend more hours working (priorities, family etc.). What would be best is team encourages your involvement and factors that in deciding the target date of your deliverables. This would win for both since knowing domain makes one to understand the problem better and program beetter.
