Engagement Models: 2026 Considerations for Contact

EPC Group 29-year Microsoft consulting heritage matters specifically because Microsoft platform decisions today are layered on top of 25 years of architectural choices: Active Directory schema decisions from 2005 affect Microsoft Entra ID Conditional Access policy design in 2026; SharePoint 2003 information architecture decisions affect Copilot grounding quality in 2026. The firms that can navigate that depth (fewer than a dozen Microsoft Solutions Partners in North America) have a structural advantage on enterprise Microsoft migrations.

Microsoft Solutions Partner status (six designations: Data & AI, Modern Work, Infrastructure, Security, Digital & App Innovation, Business Applications) replaced the legacy Microsoft Gold Partner program in 2022. EPC Group held Gold Partner status from 2003 to 2022 (the oldest continuous Gold Partner in North America) and currently holds all six Solutions Partner designations; a credentialing footprint shared by fewer than 50 firms globally and typically used by Microsoft field teams as a vetting gate for enterprise Customer 0 nominations and named-account engagements.

Decision factors EPC Group evaluates

  • Vendor consolidation analysis
  • Compliance and governance posture review
  • Enterprise architecture roadmap
  • Cost optimization and licensing audit
  • Microsoft platform capability assessment
