Run Your First Loop This Week

1. Monday: Write one hypothesis in this format: 'We believe [user] will [do behavior] because [reason]. We will know we are right if [metric] moves by [threshold] within [time window].'

2. Tuesday: Identify the smallest build that tests only that hypothesis. Scope it to 3 days maximum.

3. Wednesday to Thursday: Build and instrument. Do not add features. Do not change the hypothesis.

4. Friday: Review the metric. Hold a 30-minute debrief. Write one sentence: what did we learn and what does that mean for next week?

One loop per week means 50 validated learnings per year. Most teams get fewer than 10. The compounding advantage belongs to whoever runs the tightest loop.
