The tool is called: “One, Some, All”.
If you want to get the group engaged, and you want to get them to start participating, do it in a way that’s safe and progressive.
First, you say, “On your own, think about this. Write down any ideas that you might have. Take 90 seconds.”
Then, to a small group, (or just lean to your neighbor sitting next to you). “Talk about what you all have.” As a group gets bigger, you need to give more time, from 90 seconds, give them 3 minutes.
Finally, “Ok, now. Who wants to start us on the conversation?” Boom! Immediately 4 hands go up.
So it’s: One (On your own), Some (At your table), All…
I’m David Marquet, that’s your leadership nudge.
