Difference-in-differences for policy pilots

The advanced question in difference-in-differences for policy pilots is how the model behaves when assumptions fail. A sound design makes uncertainty, constraints and fallback actions explicit.

Practitioner lens

A responsible implementation of difference-in-differences for policy pilots includes a fallback policy, approval thresholds, model-version records and a way to explain infeasible or conflicting recommendations.

First experiment

Test the method at the level where the decision is executed, then inspect how aggregation changes results.

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