Panel forecasting across product families

Forecast uncertainty needs to be measured and carried into downstream decisions. This technical note frames panel forecasting across product families as part of that full planning chain.

Practitioner lens

Model panel forecasting across product families at the granularity the business needs, but inspect whether reconciliation or aggregation changes bias, variance or the shape of the predictive distribution.

First experiment

Monitor feature drift, residual structure and changing error by segment after deployment.

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