Passenger checkpoint operations are mission-critical yet amazingly difficult to deliver reliably in a structurally unpredictable environment. The weather, a large event from a tradeshow to a major sports tournament, strikes affecting the transport industry, a volcano, the threat of terrorism– the list is endless – all challenge even the best initial sizing plan. The key is instant adaptation to sudden changes. This calls for timely information, overall and detailed visibility on the situation and smart tools to evaluate and easily choose the best options to maintain service levels in the face of unexpected challenges.
