Track outcomes customers feel and finance respects: on‑time ship rate, promise‑to‑delivery delta, contact rate, first‑contact resolution, NPS or CSAT, AOV, repeat rate, and contribution margin. Segment by cohort, device, and channel. Tie dashboards to alert thresholds so drift never surprises you. When metrics move, you’ll know exactly which lever to adjust next.
Sequence changes to avoid peak seasons and critical campaigns. Use feature flags, dual‑running systems, and shadow traffic to validate behavior safely. Provide agents and warehouse staff with clear playbooks and short video walkthroughs. Announce what is changing, when, and why. Tidy up deprecated workflows promptly so confusion never accumulates in the background.
