I joined a company a few years ago, and there was a long term dev that had been there forever and was now a manager and did live trainings on webex with Lucid chart, where there was no prepared docs or whatever, but he drew the architecture diagram as the training, providing detailed explanations and answering questions as the diagram went. It was astonishingly effective at getting the points driving the architecture (and the salient business context driving the architecture). Each detail and each big overarching principal stuff would come at at the time when its context was right there on the evolving diagram. i was so inspired I bought a Lucid subscription, tho I never have done such good presentations, having some pictures I find makes it easier to communicate with more people.
