Prototyping allows you to quickly test and measure what's effective and what's not working. Would it be great to launch the striking 2.0 or 3.0 with no delay in time?
The key is to create something people can interact with. Something big picture and low fidelity. Sit back and observe their interactions. Ask them to think out loud.
I've found that teams love this. We sometimes miss building things with our hands. Working with whatever resources are available nearby.
Prototyping is better communication. It is touchable, clear, and multi-dimensional.
