Make sure people understand that napkin sketches are an exploratory tool. You
will kill or transform many of the sketched out ideas during the prototyping and
testing process.
The best napkin sketches…
Contain only one core idea or direction (ideas can be merged later).
Explain what an idea is about, not how it will work (no processes or business
models yet!).
Keep things simple enough to get it in a glance (details are for more refined
prototypes later on).
Can be pitched in 10 to 30 seconds.
