Microsoft SharePoint is a web-based content collaboration and document management platform used to build internal sites (team sites, intranets/portals), store and manage files and lists, manage permissions, and enable coauthoring and workflow-style business processes—most commonly as part of Microsoft 365 (SharePoint Online) or as an on-premises server product (SharePoint Server / Subscription Edition). It integrates with Microsoft 365 apps (Teams, OneDrive, Outlook) and the Microsoft identity stack.
Primary "jobs to be done":
- Intranet / internal communications hub (news, policies, portals)
- Document management (libraries, metadata, versioning, retention)
- Collaboration workspaces (team sites, shared files, lists)
- Lightweight business process apps using Lists + Power Automate + Power Apps
- Enterprise search across Microsoft 365 content (quality varies based on information architecture and permissions design)
Product lines in practice
- SharePoint Online (Microsoft 365): SaaS; most new deployments use the cloud offering.
- SharePoint Server (on-prem) / SharePoint Server Subscription Edition: self-managed; used where data residency, legacy customizations, or strict internal network constraints exist.
