Start by framing the measurement framework around the product's core value proposition: solving customer problems via chat. Then structure your answer into layers: primary KPIs for PMF and monetization, guardrail metrics, operational definitions with formulas and attribution, target ranges with escalation triggers, and finally the 'not solved' metric with sentiment and CSAT calibration, including biases. Emphasize rigor, causality, and EU-specific considerations like GDPR.
Pro tip: Show maturity by acknowledging trade-offs between metrics (e.g., monetization vs. customer harm) and proposing a phased approach: start with proxy metrics, then validate with long-term holdouts. Also, mention that sentiment models need regular bias audits and calibration against human labels, especially for multilingual EU markets.
Identify leading indicators of product-market fit (e.g., retention, engagement depth) and monetization (e.g., conversion to paid, ARPU). Specify precise formulas and attribution windows.
Select metrics to prevent customer harm (e.g., spam rate, complaint rate, churn due to dissatisfaction) and ensure they have thresholds that trigger alerts.
For each metric, provide a clear formula, data source, and attribution rules (e.g., last-touch for conversions, time-decay for engagement). Include EU-specific data privacy considerations.
Define expected ranges based on benchmarks or pilot data, and specify what actions to take when metrics fall outside these ranges (e.g., pause rollout, investigate).
Combine sentiment model output and post-chat CSAT to create a composite 'not solved' indicator. Detail calibration process, bias assessment, and failure modes for each signal.
