Bias versus accuracy

Simple forecasting methods remain useful when their fit and limits are understood. This primer explains bias versus accuracy with a planner’s workflow in mind.

Practitioner lens

Before applying bias versus accuracy, state the unit, time bucket, planning level and horizon. Forecasts with different definitions are not comparable, even when their charts look similar.

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.
