We tend to think that we experience the world as it is. We see and hear things, store them away as knowledge, and then take new facts into account. But that's not how our brains actually work. In reality, we filter out most of what we experience, so that we can focus on particular points of interest. In effect, we forget most things so we can zero in on what seems to be most important.
Using dashboards, you can create an internal learning center with embedded videos, documentation and even slide decks from previous training sessions or summits. This keeps onboarding content accessible and eliminates the friction of toggling between tabs or tools.
