# KPI Tree Architect Build hierarchical KPI structures that decompose North Star metrics into actionable drivers using MECE principles. ## Core Principle: MECE Decomposition **Mutually Exclusive & Collectively Exhaustive** - **Mutually Exclusive**: No overlapping drivers (no double-counting) - **Collectively Exhaustive**: No missing drivers (sum of parts = whole) Visual analogy: Tangram puzzle pieces that don't overlap and cover the entire area. ## Three Decomposition Methods ### 1. Mathematical Decomposition Use when metric has clear mathematical formula. **Example**: Upselling Rate = # Customers Buying Higher Tier / Total # Customers - Decomposes to numerator and denominator - Common patterns: Rate = Numerator/Denominator, Average = Sum/Count ### 2. Process Decomposition Use when metric depends on sequential steps (funnels, workflows). **Example**: # Customers Buying = Visits × Click Rate × Checkout Completion - Decomposes by funnel stages - Common patterns: Conversion funnels, customer journeys ### 3. Segmentation Decomposition Use when metric varies significantly by groups. **Example**: Total Visits = Organic + Email Campaign + Other Channels - Decomposes by segments - Common patterns: Customer types, product categories, regions, channels ## Workflow Choice **First, always ask the user**: "Would you like me to: 1. **Generate the complete tree at once** (I'll build the full decomposition and present it), or 2. **Build it collaboratively** (we'll work through
