What’s good about communicating ideas via sketches?
They Kill ambiguity helping to envision the future. It’s as simple as that. Verbalizing an abstract thought the one that exists only in our mind is not very practical especially when we tryng to explain rather complex components.
Sketching saves the day ! Fleshing out an idea as a simple storyboard helps better define it but also help the audience build a shared understanding, because you won’t be forcing them to imagine things as much.
