## 01 · From assumptions to useful experiments.

Welcome the group. Confirm access needs and the fictional example boundary. No attendee data is sent anywhere.

## 02 · Know what good looks like.

Read each learning objective and its observable success criterion. Adapt language and pacing to this group's prior knowledge.

## 03 · A plan with room to practice.

Show the full run-of-show in the workshop room. The remaining activity windows are in agenda.csv. Review transitions and breaks for the actual group.

## 04 · Notice before interpreting

Ask for literal observations first. A pause does not prove confusion or intent. Invite at least two alternative explanations.

## 05 · Choose one useful question

Keep questions neutral. Replace 'How do we prove the new sign works?' with a question that permits the idea to fail.

## 06 · Make three alternatives visible

A polished design is unnecessary. Ask whether each alternative can answer the question or merely demonstrate an attractive solution.

## 07 · Build a reversible experiment

Review consent and privacy needs for a future real test. No outreach is performed. Keep the planned intervention small enough to stop or revise.

## 08 · Agree on the signal before the result

A small exercise does not establish statistical significance. Preserve uncertainty and sample limits. Discourage universal causal claims.

## 09 · Review, revise, leave with a next step

Ask for actionable feedback rather than a score alone. Confirm that everyone has downloaded their worksheet before closing.

## 10 · Review the work. Keep the evidence visible.

Use the full emerging/ready/strong rubric. Invite a peer to name one observable improvement, then revise the worksheet.

## 11 · Use a question to reveal the gap.

Practice answers and explanations are bundled client side for self-study. Scores are local and are not secure assessments.

## 12 · Leave with one experiment you can run.

Invite a short reflection and next action. Download the worksheet before closing the browser; it is not saved automatically.
