A decision framework for choosing between a Microsoft-specialist consulting firm and a global systems integrator.
Microsoft-specialist firms like EPC Group and global systems integrators (Accenture, Deloitte, Avanade, Capgemini, Cognizant) compete for the same enterprise Microsoft consulting work, but the right fit depends on five factors: program scale, multi-cloud breadth, regulatory baseline, governance discipline, and time-to-value. This page summarizes when each is the better choice — and where the "specialist alongside a global SI" hybrid wins.

Ten factors that drive the choice between a Microsoft specialist and a global systems integrator. Honest framing — not every factor favors a specialist.
| Factor | Microsoft Specialist (e.g., EPC Group) | Global SI (Accenture, Deloitte, Capgemini, Cognizant, TCS, Infosys, Wipro) |
|---|---|---|
| Program scale | Mid-market to Fortune 1000 | Fortune 500, multi-region, multi-year |
| Microsoft-stack depth | First-class — Microsoft is the strategic platform | Strong on M365/Azure; less deep on Power BI / Purview / Copilot governance |
| Multi-cloud breadth | Intentionally focused; partners with multi-cloud SIs | Native — AWS + Azure + GCP + on-prem orchestration |
| Regulated industries (HIPAA, FINRA, FedRAMP, CMMC, GxP, EU AI Act) | Purpose-built — Governed AI on Microsoft Framework | Available; senior tier may be thin for specialist Microsoft regulated work |
| Senior architect on every engagement | Yes — no junior consultant tier (EPC Group) | Pyramid staffing; senior architects often shared across accounts |
| Fixed-fee accelerators | Yes — Mid-Market, Enterprise, Complex Enterprise tiers | Available; often supplemented by T&M phases |
| Time-to-value (initial outcome) | 30-90 days to demonstrable outcome | Often longer due to discovery and orchestration overhead |
| Organizational change and operating-model redesign | Available; not the primary lens | First-class — strategic change management is a core practice |
| Pricing posture | 30-40% below Big 4 equivalents on fixed-fee scopes | Premium pricing supported by global scale |
| Hybrid configuration | Frequent — leads Microsoft layer alongside global SI | Frequent — leads program with specialist underneath |
Concrete answers to the six engagement archetypes EPC Group sees most often.
Microsoft specialist lead. Purview AI Hub, Audit Premium retention, Communication Compliance, and Information Barriers must be configured before Copilot license assignment. EPC Group's Governed AI on Microsoft Framework is purpose-built for this scenario.
Global SI lead with EPC Group on the Microsoft governance layer. The SI orchestrates SAP, change management, and multi-region delivery; EPC Group ensures Power BI, Fabric, and Purview are governance-correct from day one.
Microsoft specialist lead. CoE governance, workspace strategy, dataset endorsement, RLS, and capacity tuning are EPC Group's home territory. Fixed-fee accelerator available.
Often hybrid. EPC Group leads the Microsoft governance and security architecture; a change-management-led firm (Slalom, Avanade, or an internal change function) leads the people side. Both succeed when scoped clearly.
Microsoft specialist lead. EPC Group has shipped these consolidations repeatedly — semantic-model design, governance-correct migration, and trained content authors. No multi-cloud orchestration overhead required.
Microsoft specialist lead with a federal-cleared subcontractor where required. EPC Group has shipped GCC High deployments with CMMC alignment. Global SIs are available but the senior-architect Microsoft-specific work is often deeper at specialists.
EPC Group is positioned as the senior-architect-led Microsoft specialist for regulated and mid-market-to-Fortune-1000 enterprises. The differentiation is not a marketing claim — it is encoded in the Engagement Excellence Charter and the Governed AI on Microsoft Framework.
Honest qualification matters. EPC Group is the wrong choice when:
A global SI (Accenture, Deloitte, Capgemini, Cognizant, TCS) is the right primary lead when the program spans more than three workstreams beyond Microsoft (SAP, Salesforce, Workday, custom apps), crosses multiple regions with on-the-ground partner presence needed, includes major organizational change or operating-model redesign beyond technology, or requires a three-year-plus transformation timeline with multi-vendor orchestration. Global SIs are built for breadth and managed scale across many platforms simultaneously.
A Microsoft specialist like EPC Group is the right primary lead when Microsoft is the strategic data and productivity platform (not just one of many), governance and regulated-industry compliance are first-order requirements, the program needs senior Microsoft architects from day one (not staffed up through a layered pyramid), the customer wants fixed-fee accelerators and predictable scope, and time-to-value matters more than breadth. This is the EPC Group sweet spot — hundreds to tens of thousands of users on a Microsoft-centric stack with regulatory exposure.
In large Fortune 500 transformations, EPC Group frequently leads the Microsoft governance and analytics layer (Power BI, Microsoft Fabric, Microsoft Purview, Microsoft 365 Copilot, Entra ID Conditional Access for AI) while a global SI orchestrates the broader program (multi-cloud, ERP modernization, organizational change, multi-region deployment). The hybrid combines specialist depth where it matters with global execution scale where it matters. EPC Group has shipped engagements in this configuration repeatedly.
Global SI day-rates for senior Microsoft consultants typically run $300-$500 per hour blended through a pyramid that includes junior consultants at lower rates. EPC Group fixed-fee engagements typically cost 30-40 percent less than Big 4 equivalents because there is no junior tier and the methodology is codified — fewer hours, more decisive output. Mid-Market Foundation engagements start at $150,000 fixed-fee. Enterprise Build engagements run $350,000-$600,000. Complex Enterprise / Fortune 500 engagements run $800,000-$2,000,000.
EPC Group is deliberately Microsoft-centric. Customers with AWS-primary or Google Cloud-primary estates should pair EPC Group with a multi-cloud SI rather than expect EPC to lead Snowflake, Databricks on AWS, or Salesforce-primary work. The intentional focus is what produces Microsoft-stack depth — across Power BI, Microsoft Fabric, SharePoint, Teams, Entra ID, Purview, Copilot, and Microsoft 365. For Microsoft consolidation (migrating off Tableau, Qlik, Lotus Notes, or fragmented analytics into the Microsoft stack), EPC Group is the better lead.
Regulated industries (healthcare, financial services, federal civilian and defense, life sciences, EU AI Act-impacted operations) raise the bar on governance, audit retention, and sensitivity-label enforcement. Most global SIs have regulated-industry practices, but the regulated-tier Microsoft work — Purview AI Hub, Audit Premium retention, Information Barriers, Communication Compliance — often gets staffed at senior Microsoft architects only at specialist firms like EPC Group. For Copilot deployment in regulated tenants specifically, EPC Group's Governed AI on Microsoft Framework is purpose-built.
Senior architects (not sales) take discovery calls. Fixed-fee Readiness Assessment available before any larger commitment.
