SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This skill translates complex demand forecasting model outputs into clear, actionable explanations for demand planners and supply chain stakeholders, bridging the gap between data science and decision-making.

Core Features & Use Cases

  • Forecast Decomposition: Breaks down forecasts into baseline, trend, seasonality, promotions, price, and external factors.
  • Accuracy Metrics: Computes MAPE, bias, tracking signal, and Forecast Value Added (FVA).
  • Error Attribution: Identifies root causes for forecast deviations like promotion changes, distribution gaps, or external shocks.
  • Narrative Generation: Creates planner-friendly explanations of forecast performance.
  • Recommendation Synthesis: Suggests actions to improve future forecast accuracy.
  • Use Case: A demand planner can ask "Why did the forecast for SKU X at Location Y change so much?" and receive a clear explanation, including the impact of a recent promotion or a shift in seasonality, along with recommendations for adjustments.

Quick Start

FAQPage Schema
How do I explain demand forecast deviations to demand planners?

Explain demand forecast deviations by decomposing statistical outputs into baseline, trend, seasonality, and promotion drivers, then generating planner-friendly narratives that quantify impacts and attribute errors to root causes.

How do I attribute demand forecasting errors to root causes like promotion changes?

Attribute demand forecasting errors by analyzing historical actuals, promotion calendars, price history, and external signals to identify root causes like distribution gaps or external shocks, quantifying their specific impact on the deviation.

What demand forecasting accuracy metrics should I track for S&OP?

Track MAPE, bias, tracking signal, and Forecast Value Added (FVA) to measure demand forecasting accuracy for S&OP, enabling clear evaluation of model performance and value contribution across the supply chain planning cycle.

Can I use historical actuals and promotion calendars to improve forecast accuracy?

Use historical actuals and promotion calendars to improve forecast accuracy by decomposing past deviations, identifying bias patterns, and synthesizing actionable recommendations to adjust future baseline, trend, and seasonality expectations.

What is the best way to translate statistical demand forecasting outputs into business narratives?

Translate statistical demand forecasting outputs into business narratives by breaking down forecasts into actionable drivers, calculating accuracy metrics, and synthesizing recommendations that bridge data science outputs with supply chain decision-making.
