Accor between 2014 and 2018 will invest about $284 million in a "digital strategy"

including the development of a single mobile app "incorporating all of Accor's services before, during and after hotel stays," the hotel company announced Thursday. Accor also plans to develop capability for "online booking of seminar facilities" as well as online check-in. Accor plans to dedicate about 60 percent of the investment to "improving middle and back-office solutions," with the remainder "used to expand market share and optimize distribution unit costs."
