FAQ, sources, licence
Every question, every source, and the Creative Commons terms.
Read →Challenging, exciting, interesting, educational. I liked that in the legal track, there was a real industry practitioner who had first hand experience with user problems we tried to solve.

The templates, ready to steal
A good brief defines the user, their context, and their goal, then stops. Nothing about the solution; the solution belongs to the teams. The one I wrote for Ionian Technologies, 31 words:
"How might we help a returning 25-year-old Zara shopper open the app at 7:45 a.m. and choose a complete outfit from her saved looks and today's feed in under 90 seconds?"
- • The user is a person you can picture and recruit, not a segment
- • The timestamp sets constraints no feature list could
- • The 90 seconds is a finish line a judge can check with a stopwatch
- • No screen or feature named, so four teams can serve it four different ways
Write yours in that shape, aim for around 31 words, then test it on one person and watch their face.
It became clear to me that spinning up several working MVPs of the same idea — each implemented differently, with a different preset of features and design — is a genuinely fast task, and one that helps you figure out much earlier, right at the brainstorming stage, what actually belongs in the final version. I'm definitely adding this to my toolkit.

Used the playbook? Tell me.
Run a day from this book and write to me: what worked, what broke at 11:40, what your room decided. Every version of this playbook got better because a facilitator somewhere was honest with me. You ran it, you get the credit, and version 2.2 gets your fix.
