Assess learners' understanding of trade-offs in sustainable supply chains across environmental, economic, and social dimensions. Scope includes decision-making across procurement, production, logistics and end-of-life; common metrics (carbon, waste, cost, labor/working conditions); frameworks such as life-cycle assessment, cost–benefit and stakeholder analysis; and strategies like circular economy and supplier engagement. Quiz items will test conceptual understanding, interpretation of case data, and the ability to analyze and justify trade-offs in realistic scenarios.
