I’ll assume the Agents feature is a new AI-agent product (0 to 1 launch) whose primary objectives are to deliver real user value and build repeatable usage/trust (monetisation is a secondary goal). Below is a detailed, end-to-end measurement plan you can implement: goals, user journeys, the single North Star, full KPI set with definitions & formulas, instrumentation/events, dashboards & SQL, experiment ideas, targets/guardrails, rollout/monitoring, and qualitative research.


1) Clarify Scope & Assumptions

  • Scope: Measure success of Agents feature only (not whole product).

  • Primary goal: User value → adoption → retention / monetization path.

  • Audience: Existing users + early adopters.

  • Time horizons:

    • Launch health: Day 0–30

    • Early retention: Day 31–90

    • Growth/monetization: 90–180+ days

  • Assumptions: 0→1 launch, prioritized metrics: activation, successful completion, reuse, and quality (not revenue yet).


2) Goals

User Goal: Users can delegate meaningful tasks to agents and get reliable, useful outcomes with low friction.
Business Goal: Habit-forming usage that increases retention and creates avenues for monetization (upsell, usage pricing, enterprise adoption).

Success = not just trials, but trusted repeated usage.


3) Core User Journey

Flow and the critical behaviours to measure:

  1. Discovery: User sees/learns about Agents (exposed)

  2. Activation: User creates/enables an agent (activated)

  3. First success: Agent completes a task that meets quality / success criteria (first_success)

  4. Reuse: User reuses same agent or creates another (habit)

  5. Outcome: User delegates real work (conversion to paying product or long-term retention)

Two business-critical behaviours:

  • Users run agents to successful completion (quality + outcome)

  • Users come back and reuse agents (habit)


4) The North Star
