Pereto Analysis

business analytics

slug: topic-map-business-analytics-pereto-analysis

Vocabulary:

  • pareto_principle: The 80/20 rule - often 80% of effects come from 20% of causes
  • concentration: How much of the total is accounted for by the top segments
  • cumulative_percentage: Running total of percentages as you move through ranked segments
  • lorenz_curve: Graphical representation of cumulative distribution
  • gini_coefficient: Statistical measure of inequality/concentration (0=perfect equality, 1=perfect inequality)
  • top_decile: The top 10% of segments
  • long_tail: The many small segments that individually contribute little but collectively matter
  • abc_analysis: Categorizing segments into A (vital few), B (useful many), C (trivial many)
  • herfindahl_index: Sum of squared market shares - measures market concentration
  • tail_percentage: What portion of total comes from the bottom X%

Concepts:

  • vital_few_vs_trivial_many: Small number of items drive most of the value
  • inequality_measurement: Quantifying how unevenly distributed value is across segments
  • rank_order_analysis: Sorting segments by contribution to identify top performers
  • cumulative_thinking: Understanding progressive accumulation of value
  • threshold_identification: Finding natural breakpoints for segment classification
  • opportunity_sizing: Quantifying the value concentration in top segments
  • long_tail_strategy: Whether to focus on head or tail of distribution
  • portfolio_balance: Understanding if concentration is healthy or risky

Concepts_advanced:

  • dynamic_concentration: How concentration changes over time (increasing/decreasing inequality)
  • cross_dimensional_concentration: Is concentration higher in geography vs product category?
  • pareto_efficiency: Optimal allocation where you can't improve one without hurting another
  • concentration_risk: High concentration means vulnerability to loss of top segments

Procedures:

  • rank_segments: Sort by measure value descending
  • calculate_percentiles: Determine segment's position in distribution
  • calculate_cumulative_values: Running sum of measure as you progress through ranks
  • calculate_cumulative_percentages: Running sum of % of total
  • identify_pareto_point: Find where cumulative % crosses key thresholds (80%, 90%)
  • calculate_gini: Area between lorenz curve and diagonal / total area under diagonal
  • classify_abc: Assign A/B/C categories based on cumulative contribution
  • plot_lorenz_curve: Cumulative % of segments vs cumulative % of value
  • calculate_concentration_ratios: Top 10%, top 25%, top 50% share of total

Procedures_detailed:

  • gini_calculation: 1 - (Σ[(cumPct[i] + cumPct[i-1]) × (1/n)])
  • pareto_percentage: Find n such that cumulative % >= 80% (or other threshold)
  • herfindahl_calculation: Σ(share[i]²) where share is % of total for each segment
  • abc_classification:
    • A: segments contributing to first 80% of cumulative value
    • B: segments contributing to next 15% (80-95%)
    • C: segments contributing to last 5% (95-100%)

Topics:

  • customer_value_concentration
  • product_portfolio_optimization
  • inventory_management_prioritization
  • sales_territory_analysis
  • supplier_risk_assessment
  • revenue_diversification
  • resource_allocation_optimization
  • quality_problem_prioritization
  • market_share_distribution
  • wealth_inequality_measurement

Categories:

  • distribution_analysis
  • inequality_metrics
  • prioritization_frameworks
  • risk_assessment
  • strategic_focus

Themes:

  • focus_on_vital_few: Concentrate resources where they matter most
  • understand_distribution: Are results normally distributed or power-law?
  • risk_vs_efficiency: High concentration is efficient but risky
  • actionable_segmentation: ABC analysis drives different strategies for each tier

Trends:

  • real_time_pareto: Live dashboards showing current concentration vs historical
  • predictive_concentration: Forecasting how concentration will evolve
  • multi_measure_pareto: Analyzing concentration across multiple measures simultaneously
  • dynamic_abc: ABC classifications that automatically adjust based on contribution shifts
  • concentration_alerts: Notifications when concentration crosses thresholds

Use_cases:

  • retail: "Top 20% of products generate 85% of revenue (Gini=0.72) - focus inventory on A items"
  • saas: "Top 15% of customers represent 90% of MRR - high concentration risk, need diversification"
  • manufacturing: "Top 5 defect types cause 92% of quality issues - prioritize those fixes"
  • banking: "Top 10% of accounts hold 95% of deposits - concentration exceeds risk tolerance"
  • ecommerce: "Long tail (bottom 60% of products) contributes only 8% of sales - consider delisting"
  • healthcare: "Top 20% of diagnoses account for 75% of costs - focus preventive care there"
  • marketing: "Top 3 channels drive 88% of conversions - reallocate budget from underperformers"
  • supply_chain: "Top 10 suppliers represent 70% of spend - develop backup suppliers for risk mitigation"
