# North Star Metric

Identify a North Star Metric and 3-5 Input Metrics that form a metrics constellation. Classifies the business game being played and validates against criteria for an effective North Star. Use when defining key metrics, setting up a metrics framework, or choosing what to measure.

## Domain Context

NSM is **NOT**: multiple metrics, a revenue/LTV metric (must be customer-centric), an OKR (that's a goal-setting technique), or a strategy (but choosing the right NSM is a strategic choice).

NSM **IS**: a single, customer-centric KPI that reflects the value customers get from the product and serves as a leading indicator of long-term business success. You can use Key Results (OKRs) to express expected change in NSM.

## The Three Business Games

Before identifying your North Star, classify your business into one of these three games:

- **Attention Game**: How much time do customers spend using your product? (Examples: Facebook, Spotify, YouTube, TikTok)
- **Transaction Game**: How many transactions occur between customers and your platform? (Examples: Amazon, Uber, Airbnb, PayPal)
- **Productivity Game**: How efficiently can someone complete their work or achieve their goals? (Examples: Canva, Dropbox, Loom, Notion)

## Prompt

You are a metrics strategist specializing in North Star metrics and growth measurement frameworks.

Given the following business context: $ARGUMENTS

**Step 1: Classify the Business Game**
Determine which game this company plays: Attention, Transaction, or Productivity.

**Step 2: Identify the North Star Metric**
Suggest a single metric that meets all seven criteria for an effective North Star:

1. **Easy to Understand**: Clear definition that everyone in the organization comprehends
2. **Customer-Centric**: Reflects value delivered to customers, not just revenue or activity
3. **Sustainable Value**: Indicates habits and long-term customer engagement
4. **Vision Alignment**: Represents meaningful progress toward the company's vision and mission
5. **Quantitative**: Measurable with clear, numeric tracking
6. **Actionable**: Teams can directly influence it through product, marketing, and operational changes
7. **Leading Indicator**: Predicts future business success and revenue growth

**Step 3: Identify Input Metrics**
Define 3-5 Input Metrics (also called leading indicators) that most directly influence and drive the North Star Metric. Each input metric should:
- Be easier to move in the short term
- Directly contribute to the North Star outcome
- Help identify where optimization efforts should focus

## Tips for Best Results

- Provide details about your business model and revenue model
- Share your company's vision, mission, or long-term goals
- Include current metrics you're tracking
- Mention key customer segments and use cases
- Describe the primary value you deliver to customers
