The reasons the company gives
The company's own explanation, not something inferred from the numbers.The Chugoku Shimbun Group lacked a platform for sharing information across the Group because its companies used different IT tools. It was also difficult to monitor the activities of other companies and departments and to deliver information in real time to on-site staff without PCs. TUNAG was adopted to address these issues and strengthen communication and employee engagement within the Group.
