Nowadays, ports have transformed from a purely ship-shore interface into logistical platforms where logistics-related activities occur, and are also important clusters of economic activities. The role of seaports is therefore essential since these transport nodes are important and indispensable for the effective and efficient management of flows of products and information in the supply chain. With this new role, it is critical that port personnel possess necessary competencies to contribute to port efficiency and turn the port into an effective supply chain partner. This research issue is explored through a conceptual model of competencies constructed based on thorough literature review and in-depth interviews and validated by a survey with port personnel both in Singapore and Vietnam. As a result, important managerial insights are drawn to the design and implementation of human resource development policy for ports.
