Module 1 — Demand, forecasting and overproduction
The single largest avoidable impact is making the wrong thing — this module shows why.
Every sustainability conversation that skips overproduction is avoiding the biggest number. Garments made but never sold at full value carry their entire production footprint for nothing. This module works through consumer and market intelligence, fashion forecasting and production planning: where demand signals come from, how forecast error turns into unsold stock, and what smaller, faster, better-informed buying actually requires from the supply base.
By the end of this module: Explain how demand signals and forecasting accuracy drive overproduction, and where planning discipline reduces it.
