Delivery Excellence in Microsoft Consulting: On-Time, On-Budget Results

Delivery Excellence: How EPC Group Runs Microsoft Consulting Engagements (2026)

Delivery excellence is the discipline that separates Microsoft consulting firms that ship on-time, on-budget, and audit-defensible from firms that deliver missed deadlines, scope creep, and architectures that fail compliance review. This is the working delivery framework EPC Group uses for every Fortune 500 engagement — from $50K fixed-fee assessments through multi-year $25M+ enterprise programs.

EPC Group has delivered Microsoft consulting engagements since 1997 across healthcare, financial services, government, manufacturing, and technology.

TL;DR — EPC Group's 6-Pillar Delivery Framework

Pillar	Outcome
1. Senior-architect-led	Named principal owns engagement
2. Fixed-fee anchored	Scope discipline, predictable cost
3. Microsoft Solutions Partner depth	Core designations earned
4. Audit-ready by default	Regulator-defensible documentation
5. Microsoft Copilot integrated	AI productivity baked in
6. Continuous quality	Weekly checkpoints, quarterly business reviews

Pillar 1: Senior-Architect-Led Delivery

Named Principal Per Engagement

EPC Group does NOT staff engagements primarily with junior consultants supervised by an absentee principal. Every engagement has:

• Named senior architect (10+ years Microsoft ecosystem) as engagement lead
• Named senior consultant(s) as technical leads per workstream
• Named project manager for delivery cadence
• Named compliance specialist for regulated-industry engagements
• Errin O'Connor (Founder & Chief AI Architect) as escalation backstop

Why This Matters

Microsoft architecture decisions compound. Microsoft Active Directory schema decisions from 2005 affect Microsoft Entra ID Conditional Access policy design in 2026. SharePoint 2003 information architecture decisions affect Microsoft Copilot grounding quality in 2026. EPC Group's senior architects bring this longitudinal context that junior consultants — even excellent ones — simply cannot replicate.

EPC Group Senior Architect Credentials

Senior architects typically bring:

• Microsoft Solutions Partner expertise across 1-3 designations
• Industry-specific compliance credentials (CHPS, CISSP, FedRAMP 3PAO assessor)
• 10+ years on the Microsoft platform (originated from SharePoint Server 2003-2010 era for senior architects)
• Demonstrated experience with regulated industries

Pillar 2: Fixed-Fee Anchored Engagements

Why Fixed-Fee

Time-and-materials engagements create misaligned incentives — the consultancy makes more money when work takes longer. Fixed-fee engagements align consultant and customer interests on rapid, high-quality delivery.

EPC Group Standard Fixed-Fee Engagements

Engagement Type	Investment	Duration
AI Readiness Assessment	$40K-$200K	4 weeks
Microsoft Fabric Quickstart Assessment	$50K-$120K	4 weeks
Healthcare / FS / Government Analytics Accelerator	$300K-$2M	12 weeks
SharePoint Modernization	$250K-$5M	6-30 months
Microsoft 365 Tenant-to-Tenant Migration	$300K-$8M	6-30 months
Microsoft Copilot Implementation	$200K-$3M	6-12 months
vCAIO Services	$25K-$140K/month	Ongoing
Microsoft Managed Analytics Services	$5K-$60K/month	Ongoing

Scope Management

Fixed-fee discipline requires scope discipline:

• Detailed Statement of Work (SOW) defining inclusions and exclusions
• Change request process for scope additions
• Quarterly scope-vs-budget reviews
• Microsoft Compliance Manager attestation milestones
• Monthly executive sponsor check-ins

Pillar 3: Microsoft Solutions Partner Depth

All 6 Designations

EPC Group holds core Microsoft Solutions Partner designations:

1. Modern Work — SharePoint, Teams, Microsoft 365, Microsoft Viva
2. Security — Microsoft Defender XDR, Microsoft Sentinel, Microsoft Entra, Microsoft Purview
3. Data & AI — Microsoft Fabric, Power BI, Azure OpenAI, Microsoft Copilot
4. Business Applications — Microsoft Dynamics 365, Microsoft Power Platform, Microsoft Copilot Studio
5. Infrastructure — Microsoft Azure compute, networking, storage, identity
6. Digital & App Innovation — Custom Microsoft Azure applications, Microsoft Foundry, Microsoft AI

Why Six Designations Matter

Many Microsoft consulting firms specialize in 1-2 designations. EPC Group's six-designation depth means:

• Architecture decisions integrate across pillars (e.g., Microsoft Copilot governance spans Modern Work + Security + Data & AI)
• Single accountable firm for end-to-end programs
• Cross-designation senior architects bring integrated perspective
• Microsoft escalation paths leverage relationships across product groups

Microsoft Press Authorship

Errin O'Connor is a 4-time Microsoft Press & Sams author, contributing to the Microsoft technical canon on:

• Microsoft Power BI
• Microsoft SharePoint
• Microsoft Azure
• Microsoft enterprise architecture and migrations

Pillar 4: Audit-Ready by Default

Regulator-Defensible Documentation

Every EPC Group engagement produces:

• Architecture Decision Record (ADR) with traceable decisions
• Customer-Responsibility Matrix mapping to Microsoft attestation
• Microsoft Compliance Manager assessment scoring
• POA&M (Plan of Action and Milestones) for any control gaps
• Microsoft Sentinel custom analytics rule library
• Microsoft Purview AI Hub configuration documentation
• Annual third-party assessment readiness package

Industry-Specific Frameworks

EPC Group standard regulated-industry frameworks:

• Healthcare — HIPAA, HITRUST, 21 CFR Part 11 (clinical)
• Financial Services — FINRA Rule 3110, SEC Rule 17a-4, SOC 2 Type II
• Government — NIST 800-53 / 800-171, FedRAMP, CMMC 2.0
• Pharma — GxP, FDA QSR
• EU — EU AI Act, GDPR, EU Data Boundary

Audit Response

When regulators or third-party auditors request information, EPC Group's audit-ready posture means:

• Microsoft Purview eDiscovery (Premium) for evidence collection
• Microsoft Sentinel queries for activity history
• Microsoft Compliance Manager attestation reports
• Power BI snapshot retrieval (current and historical)
• Documented runbook for response

Pillar 5: Microsoft Copilot Integrated Delivery

Microsoft Copilot in Engagement Delivery

EPC Group senior architects use Microsoft Copilot internally:

• Microsoft 365 Copilot for documentation drafting
• Microsoft Power BI Copilot for client analytics
• GitHub Copilot Business for custom code
• Microsoft Copilot Studio for project-specific custom agents

This means engagements deliver Microsoft Copilot scenarios that EPC Group's own teams have battle-tested in production.

Microsoft Copilot in Customer Outcomes

Every EPC Group engagement scopes Microsoft Copilot integration:

• Microsoft 365 Copilot governance setup
• Microsoft Power BI Copilot enablement
• Microsoft Copilot Studio agent design
• Microsoft Purview AI Hub configuration
• Microsoft Sentinel AI risk monitoring

Pillar 6: Continuous Quality

Weekly Engagement Cadence

• Monday: Stakeholder sync (15 min)
• Wednesday: Technical workstream sync (30 min)
• Friday: Demo + retrospective (60 min)
• Continuous: Microsoft Teams channel for async collaboration

Quarterly Business Reviews

• Microsoft Power BI dashboard with engagement KPIs
• Microsoft Compliance Manager score progression
• Microsoft Sentinel security posture review
• Microsoft Copilot adoption metrics
• ROI tracking against business case
• Roadmap updates

Customer Satisfaction

EPC Group standard NPS targets:

• Senior executive sponsor NPS: +50 minimum
• IT executive sponsor NPS: +40 minimum
• End-user NPS (post-rollout): +30 minimum
• Microsoft Product Group reference customer rate: 80%+ of engagements

Industry-Specific Engagement Patterns

Healthcare (HIPAA)

The engagement leads with PHI sensitivity-label rollout to Restricted-PHI tier, Microsoft Customer Lockbox configuration, OCR audit-readiness packages, Joint Commission audit-ready analytics, and Microsoft Purview AI Hub OCR-defensible attestation. EPC Group operates under appropriate Business Associate Agreements and the senior-architect bench includes credentialed HIPAA experts with direct experience walking OCR audits.

Financial Services (FINRA, SEC, SOX)

The engagement leads with Microsoft Information Barriers operations across investment-banking, equity research, sales/trading, and asset-management segments, Restricted-MNPI sensitivity-tier rollout, FINRA Rule 3110 supervised analytics, SEC Rule 17a-4 retention, and SOC 2 Type II attestation support. The financial-services bench includes senior architects with direct experience walking FINRA examinations and SEC examinations.

Government (FedRAMP, CMMC)

The engagement leads with Microsoft 365 GCC or GCC High deployment posture verification, FedRAMP-aligned continuous monitoring, CMMC Level 2 or Level 3 documentation for the Defense Industrial Base, CAC/PIV authentication, and ITAR-aware patterns where required. The government bench includes senior architects with FedRAMP 3PAO familiarity and ITAR experience.

Pharma (GxP, 21 CFR Part 11)

The engagement leads with 21 CFR Part 11 audit-trail integrity, Computer System Validation documentation for any Microsoft workload in scope for GxP, IND/NDA submission protection patterns, and Restricted-Clinical sensitivity-tier rollout. The pharma bench includes senior architects with CSV credentials and clinical-trial experience.

Engagement Lifecycle Detail

Phase 0 — Pre-Engagement Discovery (Weeks -4 to 0)

Senior-architect-led discovery call (no junior salespeople). Initial scoping based on customer's estate, regulator obligations, and strategic priorities. Statement of Work draft with named senior architect, fixed-fee scope, and quarterly business-review cadence. Customer review and SOW execution.

Phase 1 — Foundation (Weeks 1-4)

Customer baseline assessment across the relevant Microsoft Cloud surface. Microsoft Compliance Manager baseline score capture. Microsoft Sentinel custom-analytics rule library deployment. Runbook documentation. Customer team training so the customer's team can partner on triage when needed.

Phase 2 — Build (Weeks 5 through engagement completion)

Workstream execution per the Statement of Work. Weekly stakeholder sync, Wednesday technical workstream sync, Friday demo plus retrospective. Continuous Microsoft Teams channel for async collaboration. Microsoft Compliance Manager attestation evidence captured continuously.

Phase 3 — Hand-off and Steady-State

Engagement completes with documented runbooks, Microsoft Compliance Manager attestation package, and post-engagement transition plan. Most customers transition into EPC Group's managed-services tier model for ongoing operations under named-architect continuity. Customers without ongoing managed services receive a 90-day post-engagement support period.

Risk Mitigation Patterns

Compliance Risk

Every engagement includes Microsoft Compliance Manager attestation against the customer's applicable industry frameworks. Customer-Responsibility Matrix is operationalized with named owners for each customer-side control. Plan-of-Action-and-Milestones is tracked for any control gap with quarterly board reporting.

Schedule Risk

Wave-based delivery structure spreads complex workstreams across waves rather than concentrating them in a single wave. Quarterly scope-versus-budget reviews catch scope drift before it accumulates into schedule risk.

Quality Risk

Senior-architect-led delivery model means the most-experienced architects are personally responsible for architecture decisions rather than reviewing junior work after the fact. Microsoft Product Group reference relationships provide escalation paths for hard problems.

Personnel Risk

Mission-Critical engagements include a named senior architect bench backup so the engagement does not single-thread on one person. Customer success manager runs the relationship cadence and provides continuity if individual personnel transitions occur.

Frequently Asked Questions

How does EPC Group differ from larger firms?

Tier-1 firms (Accenture, Deloitte, PwC, KPMG, EY) bring brand recognition and global staffing. EPC Group brings senior-architect-led delivery, Microsoft Solutions Partner depth across core designations, fixed-fee discipline, and Microsoft Press-author technical leadership. For Microsoft-anchored Fortune 500 engagements where cross-pillar architecture quality matters more than global branding, EPC Group is typically a stronger choice.

How does EPC Group differ from boutique firms?

Boutique firms typically specialize in 1-2 Microsoft pillars (e.g., Power BI-only, SharePoint-only). EPC Group's six-designation depth means single-firm accountability for end-to-end programs. For multi-pillar transformations (Microsoft 365 + Microsoft Fabric + Microsoft Copilot + Microsoft Dynamics 365), EPC Group's integrated perspective is materially stronger.

What about Microsoft direct engagement?

Microsoft Industry Solutions Delivery (ISD) and Microsoft FastTrack are excellent for Microsoft-led architecture validation. EPC Group typically partners alongside Microsoft on multi-year programs — Microsoft brings product-group depth; EPC Group brings industry-specific delivery and ongoing operations.

What if we already have an internal Microsoft team?

EPC Group augments internal teams. Common patterns:

• EPC Group senior architects partner with internal architects on strategic decisions
• EPC Group delivers specific workstreams (Microsoft Copilot, Microsoft Fabric) while internal team handles operations
• EPC Group provides vCAIO services for AI strategy without replacing internal CIO / CDO

Who delivers EPC Group engagements?

Errin O'Connor (Founder & Chief AI Architect, 4-time Microsoft Press & Sams author) leads EPC Group. Senior architects with combined healthcare, financial services, government, manufacturing, and technology experience deliver client engagements.
