SharePoint can help businesses in five key ways: 1. Provide multi-platform access through features like BYOD, cross-platform browsers, and non-enterprise device authentication. 2. Enable business process management with workflows, version control, managed metadata, and workspaces for collaboration. 3. Facilitate work performance reporting using business intelligence, performance point services, Excel services, and Power View. 4. Implement federated access and control through single data aggregation and internal, partner, and public access controls. 5. Establish a SKMS (Secure Knowledge Management System) to provide the right information to the right people at the right time through various SharePoint features.
