What product measurement is for

Product measurement exists to help teams make better product decisions. It is not only about tracking performance, producing reports, or filling dashboards. Those things can be useful, but they are not the purpose of measurement.

Measurement is useful when it helps a team understand behaviour, evaluate change, identify problems, spot opportunities, or decide what to do next.

Good product measurement helps teams answer questions such as:

  • Are users able to complete important workflows?
  • Where are users struggling or dropping out?
  • Is a product change having the intended effect?
  • Which problems are worth investigating?
  • Which opportunities should we prioritise?
  • Are we improving something that matters?

When to use this

Use this article when a team is asking for “more metrics”, a new dashboard, or a reporting view, but has not yet agreed what decision the measurement should support.

It is also useful when a metric exists but nobody can explain what question it answers.

Product question → decision examples

Product question Possible evidence Possible metric Decision supported
Are users able to create an account and access the product? Registration events across form, email verification, and first access Registration completion rate Where should we improve the registration workflow?
Are mobile users struggling to complete checkout? Checkout events by device type Mobile checkout completion rate Should we prioritise mobile checkout fixes?
Are users getting stuck while creating a plan? Plan creation steps, errors, and completion events Plan creation completion rate Which step should we simplify or investigate?
Are users returning after first use? First-use and return events Repeat use rate Should we improve onboarding, reminders, or product value moments?

Measurement starts with questions

Useful measurement starts with a question, not a chart. A team should not begin by asking what they can report. They should begin by asking what they need to understand.

Instead of asking:

What metrics should we put on the registration dashboard?

A team might ask:

Are users able to create an account and access the product without unnecessary friction?

That question gives measurement a purpose. It points the team towards the workflow, the behaviour they need to observe, and the evidence they need to capture.

Without a clear question, measurement becomes a collection of numbers with no obvious use.

Measurement connects behaviour to decisions

Product teams make decisions about journeys, features, content, priorities, trade-offs, and investment. Those decisions should be informed by evidence of user behaviour.

Measurement helps create that connection:

User behaviour
↓
Evidence
↓
Insight
↓
Decision

A user submits a form. A user encounters an error. A user verifies an email. A user completes a workflow. These behaviours can be captured as evidence, turned into metrics, and used to decide what to investigate, improve, keep, remove, or prioritise.

The metric is not the end point. The decision is the point.

Reporting is not the same as measurement

Reporting tells a team what happened. Measurement helps a team understand what happened well enough to respond.

A report might show that registration completion has fallen. That is useful, but it is only a signal. The team still needs to understand where the fall is happening, which users are affected, and what response would make sense.

A measurement approach would ask:

  • Did fewer users start registration?
  • Did more users abandon the form?
  • Did validation errors increase?
  • Did users fail to verify their email?
  • Did users complete registration but fail to access the product?

These questions turn a reported number into a product investigation.

Metrics need a job

Every useful metric should have a job. It might help a team monitor a workflow, diagnose a problem, evaluate a change, compare alternatives, prioritise work, or understand progress towards an outcome.

A simple test for any metric is:

What decision could this metric support?

The answer does not need to be immediate or dramatic. Some metrics are used for monitoring, some provide context, and some help teams spot changes over time. But the metric should still have a reason to exist.

Measurement improves confidence

Product measurement rarely gives perfect certainty. Products change, users behave in unexpected ways, data can be incomplete, and events may be missing, duplicated, or poorly defined.

The goal is not to remove all uncertainty. The goal is to improve confidence.

A team may not know exactly why every user abandoned a workflow, but they can gather enough evidence to make a better decision. They can see where drop-off is concentrated, compare behaviour before and after a change, segment the data, and combine analytics with user research or support insight.

Good measurement does not make decisions obvious. It helps teams make them more responsibly.

Measurement is a shared practice

Product measurement is not only an analytics task. Product managers define the questions. Designers and researchers help explain the workflow and user behaviour. Engineers implement instrumentation. Analysts turn evidence into metrics and insight. Leaders use measurement to understand progress and make trade-offs.

When these disciplines work separately, measurement becomes fragmented. When they work together, teams can agree what matters, what should be captured, how metrics should be defined, and how the evidence will be used.

That shared understanding is often as valuable as the metric itself.

How to apply this

Before creating, requesting, or reviewing a metric, ask:

  • What question does this metric help answer?
  • What decision could it support?
  • What user behaviour sits underneath it?
  • What evidence do we need to capture?
  • What would make us confident enough to act?

These questions help teams avoid measuring what is merely available. They help teams focus on measurement that supports product decisions.

  • The Workflow–Event–Metric model
  • Metrics should answer questions
  • Designing dashboards around decisions

Key takeaway

Product measurement is for decision-making.

A useful metric should help a product team decide, learn, or improve. If it does not, it may still be a number, but it is not yet doing useful work.
