Hotel chain Accor has deployed a cloud-based communications platform to support 170,000 staff across 92 countries.
Accor has created the AccorLive intranet and AccorLounge social media network to improve collaboration across the company.
Virginie Sido, senior vice president at Accor, said: "This collaborative and user-tailored system is particularly remarkable because of its international scope and operational footprint.
"In the head offices and hotels - whether they are owned, leased or franchised - general managers, housekeepers, receptionists or head chefs can access these new solutions from any computer, whether work or personal, a tablet or a mobile phone."
The platform has been developed with Microsoft and Orange Business Services, and uses SharePoint 2013 for the internal intranet, and Sharepoint online and Office365 in the cloud for the social media network.
Laurent Idrac, Accor CIO, said: "Thanks to the cloud, employees are able to connect from any type of professional or personal device, to benefit from a large-scale and secure sharing and file storage space and permanently evolving features.”
An Accor Apps space allows users to display the apps they use every day on their main page, like booking tools, photo libraries, leave applications and training catalogues.
On the social network staff can create a community that can be either public or private, so they can exchange professional ideas. For example, head chefs, who tend not to be very mobile and rarely have contact with fellow head chefs, will be able to create their own community to share good practices and highlight their expertise, including original recipes.
All social network users are entitled to 25GB of online storage space for professional files, including documents, videos and images.
