I’ve sat in countless AI measurement debates and noticed a recurring gap. One major voice has been noticeably underrepresented in the AI measurement conversation: the product manager (PM) that’s leading development. From experience, PMs and developers do need different measurement tools—and making those differences explicit is exactly what speeds up decisions and improves outcomes.
Developers optimize the model and system layer. Their toolkit centers on eval-driven development: offline evals, regression suites, red-teaming, latency and throughput monitoring, token cost tracking, and hallucination rate reduction. On the delivery side, engineering teams watch DORA metrics alongside CI/CD performance to keep iteration fast and safe. When building LLM-backed experiences, they also care deeply about retrieval-first pipeline quality and context window management because those mechanics determine grounding, relevance, and consistency.
PMs, by contrast, own outcomes. We instrument user journeys end to end and define a clear north-star tied to value: activation, time-to-value, task success rate, retention analysis, support deflection, and revenue contribution. We rely on A/B testing frameworks and minimum detectable effect (MDE) planning to separate real impact from noise, and we consolidate behavioral signals in a unified analytics platform like Amplitude analytics and Pendo to understand adoption, friction, and cohort differences. This is the heart of product-led growth and continuous discovery: evidence, not anecdotes.
The fact that these toolboxes differ is a strength, not a weakness. Specialized metrics keep responsibilities crisp: developers guarantee model quality and reliability; PMs guarantee that quality translates into customer and business outcomes. What we need is an explicit metrics ladder that connects layers—model-level quality floors and SLOs, feature-level KPIs, and company-level results—so trade-offs are transparent and prioritization is principled.
In practice, I create a shared measurement contract for every AI initiative. It links eval sets to user-facing success criteria, defines acceptance thresholds, and spells out observability across the stack. We include governance from day one—AI risk management, privacy-by-design, and data governance—so we can scale responsibly without slowing teams down.
Here’s the AI product toolbox I give my teams: start with a concise value hypothesis; define a success rubric the customer would recognize; instrument the happy path and the failure path; plan experiments with MDE up front; segment results by persona and job-to-be-done; and close the loop with qualitative feedback inside the product via in-app guides, product tours, and lightweight surveys. For AI features specifically, add Agent Analytics for agentic AI, capture grounding sources for explainability, and log model/context inputs to make debugging and iteration repeatable. That way, LLMs for product managers stop being magic and start being manageable.
When we roll out a new assistant—whether a retrieval-augmented copilot or a voice AI agent—we set two dashboards: one for developers (eval pass rates, latency, context integrity, error budgets) and one for PMs (activation, task completion, deflection, satisfaction). The dashboards read differently by design, yet they are joined at the hip by shared definitions and experiment IDs. This lets us move quickly with confidence: engineering can tighten quality loops while product steers toward the outcome that matters most.
If you’re feeling the tension between model metrics and product metrics, don’t collapse them—connect them. Start with a thin slice, agree on 3–5 measurable outcomes, and let your evals and A/B tests work together. With a clear metrics ladder and a unified analytics platform, PMs and developers can each excel at their craft and still ship AI that customers love.
