High-Documentation is so out of fashion, for all the wrong reasons. If you are designing anything that is intended to last longer than 6 months, documentation is a critical part of the system. Meetings are great for communicating with people here and now, but only writing can communicate with people from the future. When you meet with your current colleagues, spare a thought for your future colleagues who haven’t yet…
Agile taught us working software over comprehensive documentation, but it also made huge generation of people thinking that all documentation was bad, and not just "comprehensive" (or "overblown").
Documentation (words) is how many complex concepts are communicated.
I've built a requirements management system to handle this (https://userdoc.fyi), and it's made many projects I've worked on 200% easier for developers, project managers, and all stockholders.
I think high-Documentation is out of fashion as a reaction to agile, but things are swinging back the other way.
