The challenges of supplier selection

Focus on price and quality: Many purchasing decisions are based solely on cost and product quality—other factors such as capacity, communication, or compliance are not taken into account.
Insufficient transparency: Without a structured evaluation process, essential data such as financial stability or quality control remain unknown, leading to unpredictable risks.
Risk of supply interruptions: Unevaluated capacities, lack of controls, or unstable finances can lead to delays or failures in production.
Cultural discrepancies: If suppliers do not fit in with your own values and sustainability requirements, cooperation and long-term development will suffer.
