As a result, EPC Group offers best practices that include:
Since the release of SharePoint Team Services in 2001, we have guided enterprises through every major version and architectural change. This includes:
Since the beginning of Project Tahoe, I have seen SharePoint evolve. It has transformed from a simple document management tool into a vital platform for enterprise collaboration and AI-driven content management.
The core principles of effective governance remain unchanged, but the features have improved greatly.

Common questions about SharePoint governance, security, and implementation
A SharePoint Governance Committee is a cross-functional team responsible for defining policies, standards, and procedures for SharePoint usage across your organization. It typically includes IT, legal, compliance, and business stakeholders. The committee ensures consistent site provisioning, security controls, content lifecycle management, and user adoption strategies. Without governance, SharePoint deployments often result in sprawl, security gaps, and poor user experience.
A proper SharePoint security model follows the principle of least privilege using SharePoint groups (Owners, Members, Visitors) and Microsoft 365 Groups. Best practices include: never breaking permission inheritance unless absolutely necessary, using security groups instead of individual permissions, implementing sensitivity labels through Microsoft Purview, enabling conditional access policies, and conducting quarterly permission audits. External sharing should be restricted and governed with link expiration policies.
SharePoint Power Users are business users with advanced knowledge who serve as first-line support and champions within their departments. They understand site creation, list/library configuration, Power Automate workflows, and governance policies. Develop Power Users through structured training programs, certification paths, and regular community sessions. They reduce IT burden, accelerate adoption, and ensure business-driven configuration aligned with organizational needs.
AI integration with SharePoint has become essential through Microsoft Copilot, Microsoft Syntex, and Purview. Copilot enables natural language queries across SharePoint content, automatic document summarization, and intelligent search. Syntex provides automatic content classification, metadata extraction, and retention label application. Organizations need AI governance policies defining acceptable use, data boundaries, and compliance requirements. The integration of AI is moving from optional to mandatory for enterprise content management.
Modern SharePoint Records Management centers on Microsoft Purview retention labels rather than legacy Records Centers. Best practices include: defining retention schedules based on regulatory requirements (GDPR, HIPAA, SEC), using event-based triggers for disposition, enabling automatic classification with Syntex, implementing disposition reviews for sensitive records, and maintaining audit trails. The trend is moving from site-specific records management to unified, platform-wide governance across SharePoint, Teams, and Exchange.
Effective SharePoint ECM requires: defining content types and site columns at the root site level (not subsites), using metadata instead of folders for content organization, implementing document lifecycle policies, enabling version history with appropriate limits, configuring content approval workflows, and integrating with Microsoft Purview for compliance. Avoid renaming native fields like Title, and use remote provisioning for consistent Information Architecture across sites.
Modern SharePoint intranets should leverage: SharePoint home sites for organization-wide landing pages, Viva Connections for personalized employee experiences, news posts with audience targeting, mega menus for intuitive navigation, multilingual support for global organizations, and mobile-first responsive design. Content should be governed with publishing approvals, and analytics should track engagement. Integration with Teams, Viva Engage, and Stream creates a unified digital workplace.
SharePoint collaboration best practices include: using Microsoft 365 Groups for team sites, enabling co-authoring with AutoSave, implementing @mentions and comments, integrating with Teams for real-time communication, using Planner for task management, configuring alerts and flows for notifications, and enabling guest access with appropriate controls. Train users on version history, check-in/check-out when needed, and document library best practices to prevent file conflicts.
With SharePoint experience dating back to Project Tahoe since 1997, EPC Group delivers enterprise governance, security, and AI integration solutions that work.
In 2026, SharePoint best practices center on five main areas:
EPC Group has applied these practices in over 6,500 SharePoint environments since 1997.
This guide highlights patterns that lead to:
Poor content management creates findability failures and compliance gaps. Follow these ECM fundamentals:
SharePoint collaboration works best when it is structured. Use Microsoft 365 Groups as the foundation:
Governance is what keeps SharePoint usable at scale. Without it, sprawl and orphaned sites accumulate fast.
Hub-spoke is the recommended information architecture for SharePoint Online in 2026. EPC Group uses one hub per business unit with five to fifteen spoke sites.
Client results after migrating to hub-spoke flat IA:
Modern SharePoint intranets use communication sites, not team sites. Design for the mobile reader first.
Microsoft 365 Copilot uses SharePoint as a grounding source. Poorly governed SharePoint produces poor Copilot results.
Most SharePoint environments have legacy content that needs cleanup before migration. EPC Group uses two primary migration tools:
Pre-migration best practices:
Governance before sprawl. The single biggest SharePoint failure pattern is site sprawl — hundreds of sites with no owners, inconsistent permissions, and no retention policies.
Establish a governance framework before you allow self-service site creation. Define who can create sites, what naming conventions apply, and who is accountable for each site.
Use metadata instead of deep folder structures. While folders are common, they can obscure content from search and complicate permissions.
Metadata columns enable users to:
For effective organization, follow these guidelines:
Three controls work together to manage site requests effectively:
Third, conduct quarterly access reviews. These reviews will identify sites with no active owner and no activity in the last 90 days. After confirmation, delete or archive those sites.
A hub site is a SharePoint site that brings together navigation, search, and news from related spoke sites.
It is important to create a hub site for each major business unit or division.
Connect team sites and communication sites to the hub as spokes. This arrangement makes the hub site the main starting point for that business unit's SharePoint experience.
There are three essential steps to follow:
EPC Group's governance assessment lasts two weeks. For a mid-market tenant with 500 to 5,000 seats, implementing the full hub-spoke architecture and sensitivity-label structure typically involves:
Achieving full Copilot readiness, which includes semantic index tuning, requires an additional 30 days.
EPC Group has applied SharePoint best practices in over 6,500 environments. Our team has experience with every SharePoint version since 2001. We provide:

Modern SharePoint best practices bind to the broader Microsoft 365 platform fabric: Microsoft Entra ID for identity and conditional access, Microsoft Defender XDR for unified threat protection, Microsoft Purview for sensitivity labels, retention, and DLP, Microsoft Sentinel for SIEM correlation, Microsoft Loop for portable collaborative components, Microsoft Viva for the employee-experience layer, Microsoft Stream for hosted video, and Microsoft Syntex for AI-driven document processing. EPC Group treats these as non-negotiables on regulated tenants.
