Why EPC Group for Enterprise SharePoint

1. Senior-Architect-Led Delivery

Every SharePoint engagement has a named senior architect with 10+ years SharePoint experience. EPC Group does NOT staff engagements primarily with junior consultants supervised by an absentee principal.

2. Microsoft Solutions Partner Depth

EPC Group holds core 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 & Sams 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.
