Simple exponential smoothing

Forecasting is a structured estimate for a defined decision, horizon and level of detail. This guide introduces simple exponential smoothing and shows where it fits in a practical planning cycle.

Practitioner lens

Segment performance when assessing simple exponential smoothing. Results for stable, high-volume items can hide poor performance for intermittent or newly launched products.

First experiment

Record the forecast, override and outcome separately so the next review can distinguish model from judgment.

This is an original educational brief. It is a starting point for discussion, not a claim that one technique fits every supply chain.
