Accenture is a large global consulting firm that initially used IBM Lotus Notes for knowledge management but faced issues with its unfriendly interface and limited functionality. It has now shifted to using Microsoft SharePoint, which started in 2013 and was fully implemented by 2015. SharePoint provides improved search capabilities and a common server for easier content management compared to the decentralized databases in Lotus Notes. The transition allows Accenture to better leverage knowledge across projects and business units through a more user-friendly system.
