> My latest line of thinking is that I need a way to show the user interface, and then the data flow and logic all the way back through the system (usually a back-end DB or a customer legacy system). Yes, this. It's what I've wanted as a software engineer and as a product manager. A unified overview. I find the project materials become siloed, and cross-referencing is time-consuming, error prone, and not done enough. There is often a written spec, and a separate set of wireframes, with clickable areas to show interactions. Those two need to be merged together. Then a bunch of JIRA tickets, again separate. These need to be associated with the wireframes and the spec. I have yet to find any system that makes this work.
