On-time delivery is a critical factor affecting external stakeholder satisfaction because it directly impacts the supply chain's reliability and efficiency. External stakeholders, including customers and partners, depend on timely deliveries to meet their operational and service requirements. Any delays can lead to disruptions, increased costs, and dissatisfaction. While other factors like invoice accuracy, fuel efficiency, and liability insurance are important, they do not have as immediate and significant an impact on stakeholder satisfaction as on-time delivery.References
