Why EPC Group for Enterprise SharePoint

1. Senior-Architect-Led Delivery

EPC Group holds all 6 Microsoft Solutions Partner designations — Modern Work (covers SharePoint), Security, Data & AI, Business Applications, Infrastructure, and Digital & App Innovation. This integrated depth matters for cross-pillar SharePoint architectures.

3. Microsoft Press Authorship

Errin O'Connor is a 4-time Microsoft Press author, including a book specifically on SharePoint enterprise architecture.

4. Fixed-Fee Discipline

Time-and-materials engagements create misaligned incentives. EPC Group standard is fixed-fee with documented Statement of Work and change request process for scope additions.

5. Audit-Ready by Default

Every engagement produces Architecture Decision Record (ADR), Customer-Responsibility Matrix, Microsoft Compliance Manager attestation, and audit-defensible documentation.

6. Microsoft 365 Copilot Integrated

Modern SharePoint engagements include Microsoft 365 Copilot governance setup, oversharing remediation, Microsoft Purview AI Hub configuration, and Microsoft Copilot Studio agent design.
