Frame the lesson as guided rehearsal before independent project work
Before you tackle your own café analysis project in Lessons 8-10, we're pausing for one guided rehearsal with shared teacher data.
Same data, today
Every group works with the exact same café weekend dataset. This isn't accidental — it's so you can compare your reasoning and evidence quality directly with classmates.
Guided practice for your project
Today reveals exactly what a complete project workbook must contain — the evidence chain, the Definition of Done, and how to trace a recommendation back to data.
Next lesson: Each team gets its own café scenario and dataset. The structure you learn today is what you'll carry forward into the real project.
