In addition, the business realized significant growth through acquisitions, requiring the integration of policies and consolidation of travel spend into its existing global program structure. Most significantly, the company implemented a demand management program that drove a 9 percent reduction in travel spend through a partnership with its business units based on a reduction in travel demand, policy compliance and overall reductions in pricing.In 2018, the firm will continue efforts to manage demand and costs in order to offset anticipated growth across geographies. Areas of focus include implementing an alternative lodging category strategy, refining existing travel tools to deliver a more intuitive experience, implementing a new mobile booking experience and launching a suite of business unit-level reporting to provide greater visibility into program performance and progress against goals. The team also will assess its current program and build business requirements from which it will drive a consistent and scalable service model that allows the firm to achieve its travel management objectives and deliver a superior and sustainable traveler experience.
