1. RelayOps maps interview hours to top risks: dispatcher adoption, COO budget trigger, IT integration delay. What strategic logic does this mapping follow?

2. Which Mom Test adaptation is appropriate for RelayOps B2B discovery with COOs?

3. After 10 coded RelayOps interviews, tab_switching appeared in 9/10 notes. What is the correct next synthesis step?

4. RelayOps assumption A2 targets dispatcher rebalance loop ≤120 seconds. Prototype median was 112 seconds but p75 was 145. How should the team interpret this?

5. RelayOps IT calls showed review days of 30, 45, 60, 75, 40 (median 45, two above 45). Assumption A3 status became 'At risk.' Why?

6. Which question is an anti-pattern in RelayOps dispatcher interviews?

7. RelayOps Friday synthesis promotes CRM read sync after tag frequencies update. Which mistake is avoided by weekly synthesis memos?
