name: prd-v03-outcome-definition description: Define measurable success metrics (KPIs) tied to product type during PRD v0.3 Commercial Model. Triggers on requests to define success metrics, set KPI targets, determine what to measure, establish go/no-go thresholds, or when user asks "how do we measure success?", "what metrics matter?", "what's our target?", "how do we know if this works?", "define KPIs", "success criteria". Consumes Product Type Classification (BR-) from v0.2. Outputs KPI- entries with thresholds, evidence sources, and downstream gate linkages.

Outcome Definition

Position in HORIZON workflow: v0.2 Product Type Classification → v0.3 Outcome Definition → v0.3 Pricing Model Selection

Metric Quality Hierarchy

Not all metrics are equal. Use this tier system:

Rule: Every product needs at least one Tier 1 metric. Tier 3 metrics without Tier 1/2 correlation are vanity metrics.

Product Type × Metric Selection

Metrics must align with product type from v0.2 classification:

Leading vs. Lagging Framework

Every product needs BOTH:

Leading Indicators (actionable now, predict outcomes):

• Sequences sent, open rates, trial starts
• Time to first value, activation rate
• Feature adoption in first 7 days

Lagging Indicators (confirm strategy worked):

• MRR, churn rate, LTV:CAC
• Net Revenue Retention (NRR)
• Customer count, logo churn

Pattern: Track leading weekly, lagging monthly. If leading indicators fail, you can pivot before lagging indicators confirm disaster.

Target-Setting Rules

Targets must be evidence-based, never arbitrary:

Good targets (use these approaches):

• Competitor benchmark × safety margin: "SMB churn benchmark 3-5% → use 5%"
• Revenue gates: "First dollar by Day 14" (Signal → $1: 14 days)
• Ratio thresholds: "LTV:CAC ≥ 3:1"
• Time bounds: "TTFV < 5 minutes for self-serve"

Bad targets (anti-patterns):

• Round numbers without evidence: "10% improvement"
• Engagement without revenue tie: "1000 DAU"
• Aspirational without baseline: "Best in class retention"

Output Template

Create KPI- entries in this format:

CopyKPI-XXX: [Metric Name]
Type: [Tier 1 | Tier 2 | Tier 3]
Category: [Leading | Lagging]
Definition: [Exact calculation formula]
Target: [Specific threshold with evidence source]
Evidence: [CFD-XXX or benchmark source]
Downstream Gate: [Which decision uses this — e.g., "v0.5 Red Team kill criteria"]
Measurement: [How/when measured — e.g., "Weekly via Mixpanel"]

Example KPI- entry:

CopyKPI-001: Time to First Revenue
Type: Tier 1
Category: Lagging
Definition: Days from market signal identification to first paying customer
Target: ≤14 days (GearHeart standard: Signal → $1: 14 days)
Evidence: BR-001 (GearHeart methodology)
Downstream Gate: v0.5 Red Team — if not hit by Day 21, evaluate pivot
Measurement: Manual tracking in PRD changelog

Anti-Patterns to Avoid

1. Vanity metrics as primary: "50K users" means nothing if only 500 pay
2. Traffic without quality: High volume + low engagement = quality problem
3. Arbitrary targets: "10% improvement" without baseline or benchmark
4. All lagging, no leading: Can't course-correct if you only see outcomes monthly
5. Ignoring product type: Clone metrics ≠ Innovation metrics
6. Unmeasurable outcomes: "Better experience" — how do you know?
