01

Prerequisite

What needs to be finished first

Complete firstClear scope

Agree the subject, boundary and decision before filling the model.

A broad or mixed scope produces a misleading model.
Complete firstAccess to relevant evidence

Bring source material and people who know the work; distinguish facts from assumptions.

Unverified interpretations become false certainty.
02

Preparation

What needs to be ready before start

Materials

Shared visual workspace, source evidence, and an agreed decision question.

People / roles

Product, analytics, customer research, engineering/data, decision owner.

Pre-read

Collect existing data, examples, constraints and relevant stakeholder perspectives.

Time needed

2–4 h for a working session plus data validation with analytics owners.

Setup

Describe the durable customer value the product exists to create. Propose metrics that represent that value, not output, activity or revenue alone. Check candidate for user value, influence by product/marketing and leading relationship to business results. Choose a small set of input metrics and guardrails that explain drivers and quality. Specify event definitions, segments, baseline, owner and review/correction cadence.

03

Core question

The one question this method answers

Which single metric best captures recurring customer value?

04

Flow

Phases with goal, actions, output and pitfall

Connects customer value to a leading product metric, its input metrics and guardrails.

North Star driver model

Fictional worked example

Fictional product: North Star Metric = successfully booked appointments attended per week, when both sides confirmed the appointment. Input metrics: bookable slots available, searchers selecting a slot, confirmed bookings. Guardrails: cancellation and no-show rates. Define cohorts, window and exclusions first; more bookings alone do not prove more user value.

  1. 1

    User value

    Describe delivered user value

    Goal

    Value statement

    Inputs for this step

    • Product vision, user research and use context

    Actions

    • State the repeatable value users should receive, independent of revenue or internal delivery activity.

    Output

    Value statement

    Value statement

    Quality check

    Would the metric reflect an actual user success?

    Pitfall

    More page views are assumed to equal user value. Name a completed user task or received benefit.

    Timing: Allow time according to scope and evidence; no universal duration.

  2. 2

    Candidates

    Propose and test metric candidates

    Goal

    Justified NSM candidates

    Inputs for this step

    • Events, user value and long-term business outcomes

    Actions

    • Test candidates for user value, team influence and a leading relationship to sustainable business results.

    Output

    Justified NSM candidates

    Justified NSM candidates

    Quality check

    Is it understandable, influenceable and leading?

    Pitfall

    Revenue or activity measures short-term performance only. Choose a value metric and keep business measures as guardrails.

    Timing: Allow time according to scope and evidence; no universal duration.

  3. 3

    Drivers

    Derive inputs and guardrails

    Goal

    Driver model and guardrails

    Inputs for this step

    • Candidate metric, behaviour and quality risks

    Actions

    • Derive a few observable drivers and add measures that reveal unwanted side effects.

    Output

    Driver model and guardrails

    Driver model and guardrails

    Quality check

    Are inputs plausibly causal rather than merely correlated?

    Pitfall

    Too many inputs dilute focus or invite gaming. Keep measurable drivers with a plausible connection.

    Timing: Allow time according to scope and evidence; no universal duration.

  4. 4

    Measure

    Specify measurement and review

    Goal

    Metric specification and review

    Inputs for this step

    • Event names, cohorts, windows and data owner

    Actions

    • Specify numerator, denominator, period, exclusions, segments and owner; define review triggers when product changes.

    Output

    Metric specification and review

    Metric specification and review

    Quality check

    Could two analysts calculate the same value?

    Pitfall

    Inconsistent events break the time series. Test with real events and version definition changes.

    Timing: Allow time according to scope and evidence; no universal duration.

Stop criteria

When to pause, resolve prerequisites, or choose another approach

Stop if the decision question or scope is disputed; align it first.
Stop if key inputs are unavailable; list what evidence is needed.
Stop if the group treats assumptions as observed facts.
