How do you best prepare for a Design Sprint?

No matter how many Design Sprint I've done, I always get a slight anxious feeling when​ preparing for the next one.

New team, new location, new domain. Which is great, I'm getting out of my comfort-zone.

One question that always directly comes to mind: Does the Decider know how to create a great Design Sprint challenge?

I like to be over-prepared in new situations. When something unexpected happens this gives me the mental space to think about how to best handle that. So I'll already start thinking about solutions for the challenge.

Of course it's a slippery slope. I can easily lose myself in the preparation and already be steps ahead of the team when starting on Sprint Monday. With the big risk that I'm thinking about steps that don't account for the big picture.

I created the Design Sprint Brief to help the Decision Maker get prepared and in the right mindset for ​the sprint. It makes them think about what success means for them, and how this best serves their audience. This helps them in creating a great challenge.
