Forecasting the Pulse: Data, Models, and Assumptions
Good planning begins with forecasts that acknowledge uncertainty, biases, and causal drivers. Blend adaptive time‑series methods with judgment from those closest to promotions and product changes. Incorporate leading indicators like web traffic, quote volume, macroeconomic indexes, and weather, while tracking accuracy with MAPE, WAPE, and calibration. Build transparent assumptions, publish versioned forecasts, and document overrides, so downstream teams understand why numbers shifted and where confidence is highest. This clarity powers better debates, not louder ones.
