There was a question about explaining complex business logic (the conversational stuff from the UIE podcast was part of that). I’m pragmatic about this kind of thing, so go with whatever works.
A diagram I find myself using a bit is a UML sequence or swimlane diagram. The combination of Visual Studio Code, GraphViz and a VS Code plugin is the nicest tool I’ve used for this. The plugin: Graphviz Preview - Visual Studio Marketplace, and GraphViz is https://graphviz.org/.
But I also use simple tables or random other diagrams if they make sense for the user, their problem and the document. Visualisations and other diagrams can benefit from their own user story too Visualisations and the stories behind them – Random Tech Thoughts
Someone suggested email as a kind of writing to think about. If they’re explaining emails, then I think the workshop touched on that. If they’re persuading emails or requests, I think that other UX techniques might help. I discuss this in a post that uses trying to introduce mutation testing as an example. I hope that the ideas in that can transfer to email writing. Using User Experience Techniques to Introduce Mutation Testing – Random Tech Thoughts
The person I’ve learned most UX stuff from is Paul Boag (website, podcast and Slack) https://boagworld.com/
