- Decision question
- Did the treatment earn a place in the product roadmap?
- 01 Observed evidence
Checkout initiation breaks after cart intent.
Cross-channel telemetry and session evidence point to unresolved delivery cost and reassurance before checkout.

The uncertainty arrives too late.
Fulfillment cost, timing, and progress are not visible when the shopper decides whether to continue.
- 03 Testable hypothesis
Make the commitment legible before checkout.
A side-cart treatment combining delivery reassurance and shipping progress should increase eligible checkout starts.
- 04 Controlled treatment
50/50 eligible-session exposure.
Control retained the existing cart. Treatment added the combined reassurance module with no other journey changes.
