Intent Detection

Activate this skill when the user:

• Wants to build a metric framework for a product, feature, or team
• Needs to define KPIs with leading and lagging indicators
• Asks about AARRR/pirate metrics or similar frameworks
• Wants to create a measurement or instrumentation plan
• Needs health metrics or counter metrics for existing goals
• Is preparing metrics for a product review or OKR cycle
• Asks "how do we know if this is working"

Core Principle: Every Metric Has Two Sides

This is non-negotiable in every metric framework you produce.

Every metric must be paired:

• Leading indicator: Predicts future movement. Actionable today. Input-oriented.
• Lagging indicator: Confirms past impact. Outcome-oriented. Validates the leading indicator.

If a PM cannot name the leading indicator for their goal, they are flying blind. If they cannot name the lagging indicator, they cannot prove impact.

Process

Phase 1 — Problem Clarity (Ask First)

Mandatory questions (ask all 3):

1. What are you measuring and why now? Is this a new product launch, an existing product health check, a team OKR exercise, or a specific initiative? Context determines scope.
2. Do you have a North Star metric defined? If yes, what is it? If no, we should define one first (suggest the pm-north-star skill). The entire framework flows from the North Star.
3. What is the current state of measurement? Do you have analytics instrumented? What tools are in place? (Mixpanel, Amplitude, custom, nothing?) This determines how pragmatic we need to be about what is measurable today vs. aspirational.

Contextual questions (ask if relevant):

• What teams will own metrics in this framework? (Product, Engineering, Growth, CS, Sales?)
• What is the review cadence? (Weekly product review, monthly business review, quarterly OKR?)
• Are there existing metrics that people care about but you suspect are wrong or misleading?

Wait for answers before proceeding.

Phase 2 — Framework Selection

Choose and customize the decomposition framework:

## Framework Selection

### Option A: AARRR (Pirate Metrics) — Modified for B2B SaaS
Best for: Product-led or hybrid growth motions

| Stage | B2C Definition | B2B SaaS Adaptation | Domain-Specific Example (see `domain-context.md`) |
|-------|---------------|--------------------|--------------------|
| **Acquisition** | User visits site | Account created / trial started | Trial started, source tracked |
| **Activation** | First value experience | First meaningful workflow completed | First compliant transaction completed |
| **Revenue** | First payment | First contract signed / first expansion | First paid plan activated, first add-on |
| **Retention** | Returns to product | Active usage in renewal window | Key workflow completed, data export run |
| **Referral** | Invites others | Expansion within org + word-of-mouth | Additional entities added, partner referral |

### Option B: Input-Output Tree — Custom
Best for: Established products with a clear North Star

North Star → Input Metrics (team-owned) → Health Metrics (system-level) → Counter Metrics (guardrails)

### Option C: Jobs-to-be-Done Metric Map
Best for: Multi-module products where different user segments have different jobs

Map metrics to customer jobs rather than funnel stages.

### Recommendation: [State which framework fits based on user's answers and why]

Phase 3 — Full Metric Hierarchy

Build the complete hierarchy. This is the core deliverable.

## Metric Hierarchy

### Level 0: North Star
| Metric | Definition | Owner | Cadence | Target |
|--------|-----------|-------|---------|--------|
| [North Star] | [Precise definition] | [Head of Product / CPO] | [Weekly/Monthly] | [Target] |

**Leading indicator:** [What predicts North Star movement — e.g., activation rate trend]
**Lagging indicator:** [What the North Star itself predicts — e.g., NRR, LTV]

---

### Level 1: Input Metrics
These are the levers that teams pull to move the North Star.

#### Input Metric 1: [Name] — Owner: [Team]
| Aspect | Detail |
|--------|--------|
| Definition | [Precise, unambiguous definition with counting rules] |
| Why it matters | [Causal link to North Star — not just correlation] |
| Leading indicator | [What predicts THIS metric will move] |
| Lagging indicator | [What THIS metric predicts will happen next] |
| Target | [Specific number + timeframe] |
| Cadence | [How often measured and reviewed] |
| Data source | [Where the data comes from — event, database, survey] |
| Instrumentation status | [Exists / Needs work / Not yet tracked] |

#### Input Metric 2: [Name] — Owner: [Team]
[Same structure]

#### Input Metric 3: [Name] — Owner: [Team]
[Same structure]

#### Input Metric 4: [Name] — Owner: [Team]
[Same structure]

---

### Level 2: Health Metrics
System-level indicators that confirm the product is functioning correctly. These are not directly optimized — they are monitored for anomalies.

| Health Metric | Definition | Healthy Range | Alert Threshold | Leading | Lagging |
|--------------|-----------|--------------|----------------|---------|---------|
| [Performance] | [e.g., p95 latency for key workflows] | [< X ms] | [> Y ms] | [Error rate trend] | [Task completion rate] |
| [Reliability] | [e.g., uptime for critical paths] | [> 99.X%] | [< 99.Y%] | [Deploy failure rate] | [Support tickets] |
| [Data Quality] | [e.g., booking accuracy rate] | [> 99.X%] | [< 99.Y%] | [Validation error rate] | [Correction entries] |
| [Compliance] | [e.g., regulatory validation pass rate] | [> 99.X%] | [< 99.Y%] | [Schema violation rate] | [Audit findings] |
| [Engagement Quality] | [e.g., sessions with value-action] | [> X%] | [< Y%] | [Feature discovery rate] | [Retention at day 30] |

---

### Level 3: Counter Metrics (Guardrails)
Every optimization creates a risk. Counter metrics prevent you from winning the metric game while losing the product game.

| Primary Metric Being Optimized | Counter Metric | Why | Threshold |
|-------------------------------|---------------|-----|-----------|
| Activation rate | Time-to-activate | Rushing users through setup = poor quality activation | Must not exceed [X] days |
| Feature adoption | Support ticket rate | Forcing feature usage without understanding = support burden | Must not increase > [X]% |
| Transaction volume | Error rate | More transactions without accuracy = compliance risk | Must stay below [X]% |
| User count growth | Revenue per user | Adding free/low-value users dilutes ARPU | Must stay above € [X] |
| NPS score | Response rate + bias | Cherry-picking happy users inflates NPS | Response rate must stay > [X]% |
| Onboarding completion | 30-day retention | Completing onboarding checklist ≠ finding real value | Retention must stay > [X]% |

Phase 4 — Instrumentation Plan

## Instrumentation Requirements

### Event Taxonomy
Define the events needed to power this metric framework:

| Event Name | Trigger | Properties | Metric(s) Powered | Priority |
|-----------|---------|-----------|-------------------|----------|
| [account.created] | New account registration | plan, source, segment | Acquisition metrics | P0 |
| [transaction.created] | User creates a transaction | type, amount, is_compliant, entity_id | North Star, Activation | P0 |
| [period_close.completed] | Period close finished | entity_id, duration_days, error_count | Retention, Health | P0 |
| [export.generated] | Data export run | entity_id, period, record_count, export_type | Activation, Retention | P1 |
| [feature.discovered] | User first interacts with feature | feature_name, context | Adoption, Health | P1 |
| [error.compliance] | Compliance validation failure | error_type, document_id | Health, Counter | P0 |

### Instrumentation Priorities
- **P0 — Must have for North Star + Input Metrics:** Ship within [X] weeks
- **P1 — Required for Health + Counter Metrics:** Ship within [Y] weeks
- **P2 — Nice to have for deeper analysis:** Backlog

### Data Quality Requirements
- Events must include: timestamp, user_id, account_id, session_id
- Compliance events must include: entity_id, document_reference
- Financial events must include: amount, currency, fiscal_period
- All events must be idempotent (no double-counting on retry)

### Dashboard Specification
| Dashboard | Audience | Metrics Shown | Refresh Rate |
|-----------|----------|--------------|-------------|
| Product Health | Head of Product, PMs | North Star + all input metrics | Daily |
| Team Dashboard: [Team] | Individual team | Their owned input metrics + counter metrics | Real-time |
| Executive Dashboard | C-Suite | North Star + revenue metrics + NRR | Weekly |
| Compliance Dashboard | Legal, Audit | Health metrics for compliance | Daily |

Phase 5 — Review & Governance

## Metric Governance

### Review Cadence
| Review | Frequency | Attendees | Metrics Reviewed | Decision Rights |
|--------|-----------|-----------|-----------------|----------------|
| Weekly Product Review | Weekly | PMs, Head of Product | Input metrics, counter metrics | Adjust tactics |
| Monthly Business Review | Monthly | Product + Leadership | North Star, revenue, NRR | Adjust strategy |
| Quarterly Metric Audit | Quarterly | Product + Analytics | Full framework | Revalidate or change metrics |

### When to Change Metrics
Metrics should be stable for at least one quarter. Change a metric only when:
- It no longer correlates with the North Star (proven with data, not gut feel)
- The team can no longer influence it (external dependency took over)
- The product strategy fundamentally changed
- You discover it is being gamed and cannot be un-gamed

### Metric Retirement Process
1. Flag metric as "under review" in the quarterly audit
2. Run parallel tracking of old and new metric for 4-6 weeks
3. Present comparison to stakeholders
4. Retire old metric, archive dashboards, update documentation

### Anti-Gaming Measures
- Every metric has a counter metric (see Level 3)
- Metrics are reviewed in context, never in isolation
- Teams present leading AND lagging indicators together
- "Green on metric, red on counter metric" triggers investigation

Output Format

Deliver as a structured document:

1. Framework Overview (which framework, why)
2. Complete Metric Hierarchy (all 4 levels with leading/lagging pairs)
3. Metric Definitions (precise, unambiguous)
4. Instrumentation Plan (events, priorities, timeline)
5. Dashboard Specification
6. Governance & Review Cadence
7. Known Gaps & Next Steps

Tone & Style

• Rigorous: Every metric must be precisely defined. "Active users" is not a definition. "Accounts with at least one booking created in the last 30 days" is.
• Balanced: Push for both leading and lagging on every metric. If someone gives you only lagging indicators, ask "But how will you know BEFORE the quarter ends whether you are on track?"
• Practical: If instrumentation does not exist, say so. Do not build a framework on data you cannot collect.
• Anti-vanity: Challenge any metric that looks good on a slide but does not drive decisions.
