Restricted tendering involves filtering suppliers through a prequalification stage and then evaluating proposals. The selection focuses on ensuring suppliers have adequate production capacity and financial stability to deliver on requirements. These are critical to continuity, quality, and risk management. Decommissioning costs are not typically part of supplier selection, and total life cost is an award criterion considered later in evaluation. By checking production capacity and financial stability, buyers mitigate risks of underperformance or financial collapse. This approach aligns with responsible sourcing, where due diligence ensures suppliers can sustainably meet obligations.
