    The playbook

    1. 1

      Metric 1 — Accuracy

      % of agent outputs that pass human review without correction. Target: >95% for production.

    2. 2

      Metric 2 — Deflection rate

      % of inbound tasks the agent fully handles without human escalation. Target: 60–80%.

    3. 3

      Metric 3 — Cost per task

      All-in agent cost ÷ tasks completed. Compare to human equivalent. Target: <20% of human cost.

    4. 4

      Metric 4 — Time to resolution

      Average end-to-end time from task in to task complete. Target: 5–10× faster than human baseline.

    5. 5

      Metric 5 — Customer satisfaction (where applicable)

      CSAT or equivalent on agent-handled interactions. Target: same or better than human baseline.
