RELEVANCE OF PRODUCTIVITY GAINS
SHIPPING LINESVessel turn around time (High operational savings)Schedule integrity
TERMINALEquipment OptimizationHigher number of boxes moved (Increased earnings)Operational savings (e.g. Labour)
INLAND CUSTOMERSBetter organisation of supply chainsLower levels of inventoryLower transportation costs
COMMUNITYTerminal efficiency relevant for a country’s competitiveness and economic developmentLower congestion and pollution on the roads

CONCLUSIONS
Capacity constraints, increase throughput and clients demands at the water and land sides are moving port operations inland (extended gateways)
Terminals serve two different sets of clients. High productivitymust be kept at the waterside to be competitive but it is in thehinterland where strategies and solutions for capacity, productivity and services are focused.
Productivity gains can be achieved through different mechanisms. However, start by analyzing your processes, information flow and your clients requirements before additionalinvestments are executed.
