What should you measure weekly versus quarterly for an AI product?

THE SHORT ANSWER

Use two measurement layers on purpose. On the fast cadence (weekly, and per diff) measure direction with seven leading indicators: eval pass rate, agent quality, iteration count, design coherence, escalation rate, dispute rate, and latency. On the slow cadence (monthly, quarterly) measure outcomes. The reason is timing: AI features iterate ten to twenty times a week, but an outcome cycle still runs four to twelve weeks, so by the time an outcome attributes back you have shipped forty to eighty more changes. Outcome accountability alone becomes a lagging signal that cannot drive daily decisions. Most teams run only one layer; the fix is to run both.

Outcome accountability is a luxury good. It works when you can complete an outcome cycle inside a single decision cycle. AI products break that assumption, so you need two measurement layers, deliberately. Most teams run only one.

Why one cadence is not enough

AI features iterate ten to twenty times a week. The outcome cycle for those features still runs four to twelve weeks. By the time an outcome attributes back, you have shipped forty to eighty more changes. So an outcome number, on its own, is a lagging measurement that cannot drive the decision you have to make today. You are steering with a signal that describes a version of the product you already replaced.

That is not an argument against outcomes. It is an argument for adding a second layer that moves as fast as the product does.

The fast cadence: measure direction

On the fast clock (weekly, and in practice every diff) measure direction with seven leading indicators:

  1. Eval pass rate. The share of your eval suite the current build passes.
  2. Agent quality. How good the outputs are against your rubric.
  3. Iteration count. How many times you shipped this week. Velocity is itself a signal.
  4. Design coherence. Whether the experience is holding together as it changes.
  5. Escalation rate. How often the system hands off to a human.
  6. Dispute rate. How often users push back on or correct the output.
  7. Latency. Speed, which is a quality dimension for anything interactive.

These tell you which way quality is heading before the slow outcome number can. When eval pass rate slides three weeks running, you do not wait for the quarterly outcome to confirm it.

The slow cadence: measure outcomes

Outcomes still matter. They just live on a monthly and quarterly cadence, where the cycle time actually fits. Review them the way outcome-driven planning always intended, but stop asking them to drive daily decisions they are too slow to inform.

The honest framing

This is a respectful argument with the canon, not a rejection of it. Outcome accountability was right for the products it was written about, where an outcome cycle fit inside a decision cycle. AI-native products are different. Run both layers: direction on the fast clock, outcomes on the slow one. If you only have one, add the other this week. Start with eval pass rate and escalation rate; they are the two that move first.
