The Role of Delivery Reliability on Port Supply Chain Performance at Zanzibar Port Corporation

Abstract

Delivery reliability is one of the determinants that influence the port supply chain performance; however, a lot of developing ports are lagging behind in terms of operational scale due to the insufficiencies in managing business, which leads to the weakening of competitiveness. Zanzibar Port Corporation, which controls over 95% of the island’s trade, is no stranger to problems with meeting the requisite schedules of cargo delivery, such as delays, unpredictable lead times, negatively impact the entire port supply chain performance. Based on the SCOR model and the RBV theory, this study investigated the impact of delivery reliability on port supply chain performance. It This accounted for most of the important objects of delivery reliability as: delivery on-time, tracking efficiency and order accuracy. A descriptive study design was utilized to conduct the study; a structured questionnaire was distributed to 74 port stakeholders who were randomly selected. The data was analyzed using regression and descriptive statistics. It also revealed that, on-time delivery and tracking efficiency positively influences port supply chain performance.  but and order accuracy have to be improved. The model possesses a high explanatory power (Ral2 = 0.973), that is the dimensions of delivery reliability can explain the most part of the variance of performance. This research indicates that ZPC has effective systems and procedures in place, targeted improvements to monitoring mechanisms, predictive scheduling, and consistency in OP processes could increase reliability and customer satisfaction. The implications of the findings are important for port managers and policy makers as they indicate that upgrading of internal processes and digital infrastructure within the context of the Zanzibar Economy could improve the performance of the supply chain and contribute to sustainable growth of regional trade.
