What results do enterprises achieve with Microsoft consulting?
Enterprise Microsoft consulting engagements lead to clear benefits. These include:
- 30-40% productivity improvements from platform migrations.
- $1-3M annual cost savings from analytics consolidation.
- 90%+ user adoption rates with structured change management.
- 25-35% infrastructure cost reductions from Azure cloud migrations.
Organizations that work with experienced Microsoft consultants enjoy many benefits. These experts provide:
- Governance frameworks
- Compliance knowledge
- Proven methods
As a result, they typically achieve better outcomes than those who try to make changes on their own.
- The six case studies below highlight specific results from Fortune 500 engagements.
- Industries represented include healthcare, financial services, government, energy, education, and manufacturing.
Why Case Studies Matter More Than Promises
Many Microsoft consulting firms claim to have enterprise expertise. Their presentations often include slides on "transformation" and "digital innovation." However, when a Fortune 500 CISO asks, "Show me where you've done this before — with numbers," there is often silence. This gap between marketing claims and actual results can lead to challenges in consulting relationships.
This article will explore that gap.
At EPC Group, we have spent 29 years creating Microsoft solutions for organizations where failure is not an option. Our clients include:
- Hospitals managing protected health information
- Banks processing billions in daily transactions
- Government agencies handling classified data
- Manufacturers running 24/7 production lines
The case studies on this page come from real engagements. Client names are anonymized due to NDA requirements. However, the metrics, timelines, technology stacks, and outcomes are documented facts.
These projects are not just selected examples where everything went smoothly. They reflect our work every quarter in:
- Large-scale deployments
- Regulated industries with mandatory compliance
- Aggressive timelines
- User counts in the tens of thousands
- Close scrutiny from the C-suite
If your organization is considering Microsoft consulting partners, these case studies provide a clear baseline for what experienced delivery entails.
Case Study 1: Fortune 500 Healthcare System
SharePoint Online Migration — 50,000 Users, HIPAA-Compliant
The Challenge
A multi-state healthcare system employs 50,000 people across 12 hospitals and over 200 outpatient clinics. They used SharePoint 2013 on-premises to store 4.2 million documents.
- Clinical protocols
- Patient education materials
- Administrative policies
- Departmental collaboration sites
Three prior migration attempts by other consulting firms failed:
- One stalled during the pilot phase.
- Another introduced PHI exposure risks, prompting a compliance review.
- The last was abandoned after 60 days due to poor project governance.
The CIO had a clear goal: migrate to SharePoint Online within 12 months. They needed to ensure HIPAA compliance and avoid any incidents of PHI exposure. Additionally, they aimed for measurable productivity improvements while maintaining smooth clinical operations.
The organization also faced a contract renewal for their on-premises infrastructure. This renewal would cost $1.8M annually if the migration was not completed on time.
The Solution
EPC Group used a phased migration approach with the SharePoint Assessment Tool (SMAT) for discovery. We applied our unique governance framework to classify each site collection by sensitivity level.
Before migration began, we implemented Microsoft Purview sensitivity labels across all content. This ensured that PHI was classified and protected during transit.
The migration waves were organized based on department importance:
- Administrative departments first
- Clinical support next
- Direct patient care teams last
A dedicated change management team of 8 specialists worked closely with 120 departmental champions. These champions were trained in the new platform.
We developed custom Power Automate workflows to replace 340 legacy InfoPath forms that clinical staff used every day.
We also implemented:
- Conditional Access policies to enforce compliant device access.
- Azure Private Link to ensure all data transit remained within Microsoft's backbone network.
The Results
40% Productivity Gain
Measured via time-to-document-retrieval and collaboration cycle times across clinical departments

Case Study 2: Global Financial Services Firm
Power BI Enterprise Deployment — 8,000 Analysts, Replaced Cognos
The Challenge
A global financial services firm operates in 14 countries. It uses IBM Cognos as its main analytics platform. This Cognos environment supports 8,000 analysts and portfolio managers across different divisions:
- Investment Management
- Risk Management
- Compliance
- Investment Banking
- Wealth Management
- Risk
- Compliance
However, the firm faces challenges:
- Annual licensing and infrastructure costs exceed $3.4M.
- Report development cycles take 6-8 weeks.
- The IT BI team has a backlog of over 400 report requests, growing by 30 each month.
The firm’s Chief Data Officer wanted to consolidate onto Power BI Premium. This change would:
- Reduce costs
- Enable self-service analytics
- Integrate with the Microsoft 365 environment adopted two years earlier
The challenge was significant:
- 2,400 Cognos reports needed migration or rebuilding.
- Row-level security had to enforce regulatory data boundaries between divisions.
- SOC 2 Type II compliance could not lapse during the transition.
Previous attempts to pilot Power BI had failed. Analysts rejected the new tool due to inadequate training and missing features from their Cognos workflows.
The Solution
EPC Group started with a 6-week project to improve Cognos reports. Out of 2,400 reports, only 680 were accessed in the last 90 days. We organized these reports into three tiers:
- Tier 1: Frequently accessed reports
- Tier 2: Occasionally accessed reports
- Tier 3: Rarely accessed reports
- Tier 1: Frequently accessed reports
- Tier 2: Occasionally accessed reports
- Tier 3: Rarely accessed reports
- Tier 1: 142 critical daily-use reports rebuilt first
- Tier 2: 310 weekly/monthly reports migrated in Phase 2
- Tier 3: 228 reports rebuilt on-demand as users requested them
This process eliminated 1,720 reports that were not being used, significantly reducing the migration scope and timeline.
We deployed Power BI Premium capacity in two Azure regions. This ensures geographic redundancy. We also implemented row-level security models that align with existing Cognos security groups.
Furthermore, we built a semantic layer using Azure Analysis Services. This layer helps maintain the business logic that analysts depend on.
A Power BI Center of Excellence was established with 15 trained power users who acted as divisional champions. Training was provided in role-specific modules:
- Portfolio managers received different training than compliance analysts.
- Hands-on workshops utilized their actual data sets instead of generic sample data.
The Results
$2.1M Annual Savings
Eliminated Cognos licensing ($2.8M) offset by Power BI Premium costs ($700K), net $2.1M annual reduction
70% Faster Report Delivery

Case Study 3: Federal Government Agency
FedRAMP-aligned M365 Deployment — 25,000 Users
The Challenge
A large federal agency with 25,000 employees operates across 40 field offices. They were using outdated collaboration tools, including:
- Lotus Notes for email
- Shared network drives for documents
- Skype for Business Server 2015 for communication
The agency needed to upgrade to Microsoft 365 Government Cloud (GCC High) within 12 months. This upgrade was crucial to comply with the updated NIST 800-53 requirements. Their current Authority to Operate (ATO) was about to expire. Any delay in authorization would stop operations.
The agency managed Controlled Unclassified Information (CUI), which required special handling procedures. There were also 6,000 users working in disconnected or low-bandwidth field locations.
The agency's IT staff consisted of 45 members, none of whom had experience with Microsoft 365.
The migration required continuous operations. There could be no "dark period" where email or document access was unavailable, even for a short time.
The Solution
EPC Group developed a GCC High architecture that aligns each NIST 800-53 control family with specific Microsoft 365 settings. We also created a 200-page Security Configuration Baseline document.
This document serves two key purposes:
- It acts as an implementation guide.
- It provides the necessary artifact for ATO authorization.
The migration was organized into three phases:
- Exchange Online migration with coexistence
- SharePoint Online and OneDrive deployment
- Teams deployment with voice integration, replacing the legacy PBX system
For low-bandwidth field offices, we set up Azure ExpressRoute connections. We also implemented SharePoint differential sync policies to reduce bandwidth use.
Microsoft Intune managed all 32,000 devices, including 7,000 mobile devices. It enforced encryption, pin requirements, and remote wipe capabilities.
From day one, Microsoft Sentinel was configured with custom detection rules for CUI access anomalies. This setup provided the continuous monitoring needed for FedRAMP compliance.
The Results
Zero Security Incidents
No CUI exposure, no unauthorized access, no data loss events during 9-month deployment and 12 months post-deployment
FedRAMP ATO Achieved
Authority to Operate granted on first submission — no remediation required, saving 3-6 months typical delay
25,000 Users Migrated
All users migrated across 40 field offices with zero unplanned downtime — email coexistence maintained throughout
60% Collaboration Improvement
Measured by document sharing velocity, meeting efficiency metrics, and cross-office project completion times
$2.4M Annual Savings
Eliminated Lotus Notes licensing, Skype Server infrastructure, and 3 FTE positions reallocated to modernization
9-Month Delivery
Completed 3 months ahead of the 12-month mandate, allowing buffer for ATO review and approval process
Timeline:
9 months (planning through ATO submission)
Tech Stack:
Microsoft 365 GCC High, Exchange Online, SharePoint Online, Teams, Intune, Microsoft Sentinel, Azure ExpressRoute, Defender for Office 365
Case Study 4: Fortune 500 Energy Company
Azure Cloud Migration — 200+ Servers, 35% Cost Reduction
The Challenge
A Fortune 500 energy company operates in upstream exploration, midstream logistics, and downstream refining. It was running 214 servers in two aging data centers. This infrastructure supported:
- SCADA system data collection
- Financial reporting
- ERP (SAP)
- Engineering applications
- Corporate collaboration tools
Annual infrastructure costs exceeded $4.8M. This amount included hardware refresh cycles, data center lease, power, cooling, and a 12-person operations team.
The company's CTO aimed to achieve two key goals. First, reduce infrastructure costs by at least 30%. Second, enhance disaster recovery capabilities.
The existing disaster recovery (DR) strategy relied on a warm standby data center. This center cost $1.2M annually but had never undergone full testing.
The company had to comply with regulations from NERC CIP (North American Electric Reliability Corporation Critical Infrastructure Protection). This requirement impacted the operational systems. As a result, it was difficult to transfer all workloads to the public cloud. Careful compliance mapping was essential for this process.
The Solution
EPC Group completed a 4-week Azure Migrate assessment of 214 servers. Each workload was categorized into one of four migration strategies:
- Rehost (lift and shift)
- Replatform (minor modifications)
- Refactor (significant modernization)
- Retain (keep on-premises for regulatory reasons)
We assessed 214 servers in total. Out of these, 156 were suitable for rehosting.
Additionally, we identified:
- 32 servers for replatforming to Azure PaaS services
- 14 servers for refactoring into Azure-native architectures
- 12 SCADA-related servers to be retained on-premises with Azure Arc management
We implemented Azure Landing Zone architecture with hub-and-spoke networking. We also used Azure Policy to establish governance guardrails.
Furthermore, Azure Site Recovery took the place of the expensive warm standby data center.
We used Reserved Instances and Azure Hybrid Benefit licensing for all eligible workloads. This strategy cut compute costs by an additional 40% beyond the baseline migration savings.
The SAP workload was migrated to Azure Large Instances with certified SAP HANA configurations. Additionally, Azure Backup replaced the old Commvault infrastructure.
The Results
35% Infrastructure Cost Reduction
Annual infrastructure spend reduced from $4.8M to $3.12M — $1.68M annual savings including Azure consumption
202 Servers Migrated
156 rehosted, 32 replatformed, 14 refactored — only 12 retained on-premises for NERC CIP compliance
DR RTO: 4 Hours → 15 Minutes
Azure Site Recovery replaced warm standby, reducing recovery time from 4 hours to 15 minutes with automated failover
$1.2M DR Cost Eliminated
Warm standby data center decommissioned entirely — Azure Site Recovery costs $180K annually, saving $1.02M
99.99% Uptime Achieved
First full year on Azure delivered 99.99% uptime vs. 99.7% historical on-premises availability
8-Month Migration
All 202 servers migrated in 8 months with zero unplanned production outages during migration windows
Timeline:
8 months (assessment through data center decommission)

Case Study 5: Major Research University
Microsoft Teams Governance — 40,000 Students & Faculty, 92% Adoption
The Challenge
A major research university with 40,000 students and faculty across 3 campuses deployed Microsoft Teams during the pandemic as an emergency measure. Two years later, the situation became chaotic. A total of 28,000 Teams had been created, but most were abandoned. There was no naming convention, lifecycle policy, or data classification in place.
Moreover, students created Teams that included FERPA-protected education records without proper access controls. This lack of organization and security posed significant risks.
The IT department faced significant challenges, receiving over 200 Teams-related support tickets each week.
The university's CIO wanted to transform the environment from a liability into a governed collaboration platform. This platform would:
- Enhance academic outcomes
- Support research collaboration
- Maintain FERPA compliance
- Reduce the IT support burden
There were political challenges to address. Faculty members resisted governance they believed limited academic freedom. At the same time, students wanted a simple and user-friendly experience.
Any solution that appeared bureaucratic would likely be avoided.
The Solution
EPC Group created a framework called "governance that enables." This is different from the restrictive policies that were proposed and rejected twice before.
We designed three Teams templates:
- Course Teams: Auto-provisioned from the Student Information System with correct enrollment rosters.
- Research Teams: Approved via a lightweight form with Principal Investigator verification and data classification.
- Department Teams: Provisioned by department admins with standardized channels.
The main idea was to automate provisioning. This way, users never had to think about governance, as it was built into the template.
We implemented expiration policies for Microsoft 365 Groups. These policies archived inactive Teams after 180 days. There is also a 30-day grace period for users.
Additionally, Azure AD dynamic groups managed enrollment-based access automatically.
Microsoft Purview sensitivity labels classified research data, including FERPA-protected records. Data Loss Prevention (DLP) policies prevented accidental sharing of student education records outside the university tenant.
A self-service portal, built on Power Apps, allowed faculty to:
- Request custom Teams configurations
- Avoid submitting an IT ticket
The Results
92% Adoption Rate
Measured by monthly active usage across all 40,000 users — up from 61% pre-governance implementation
28,000 → 4,200 Teams
Archived 23,800 abandoned Teams, reducing sprawl by 85% while preserving all content for compliance
78% Support Ticket Reduction
Weekly Teams-related tickets dropped from 200+ to 44 through automated provisioning and self-service portal
Zero FERPA Violations
DLP policies blocked 340+ potential FERPA violations in the first 6 months — all caught before data exposure
96% Faculty Satisfaction
Faculty rated the new governance framework 96% satisfactory — the highest IT satisfaction score in 8 years
5-Month Implementation
Full governance framework deployed in 5 months, including template design, policy rollout, and training
Timeline:
5 months (audit through governance enforcement)
Tech Stack:
Microsoft Teams, Microsoft 365 Groups, Azure AD Dynamic Groups, Microsoft Purview, Power Apps, Power Automate, SharePoint Online, Microsoft Intune for Education
Case Study 6: Global Manufacturing Corporation
Power BI Embedded Analytics in ERP — Real-Time KPIs, 28% Faster Decisions
The Challenge
A global manufacturing corporation runs 18 plants in North America and Europe. They encountered problems with fragmented analytics. Production managers relied on daily spreadsheet exports from SAP ERP.
Quality data was kept in a separate MES (Manufacturing Execution System). Supply chain metrics were sourced from another system, and financial data was stored in SAP BW.
To achieve a unified view of plant performance, data had to be consolidated manually. This process took 2 to 3 days for each reporting cycle. As a result, decisions were often based on outdated information.
The VP of Operations wanted real-time KPI dashboards integrated into the SAP Fiori interface that plant managers use daily. These dashboards needed to:
- Pull data from all four sources
- Refresh every 15 minutes during production hours
- Be accessible on tablets used on the plant floor
The earlier attempt with Tableau was abandoned. Tableau could not embed natively in SAP Fiori, and plant managers refused to use a separate application.
The Solution
EPC Group created a Power BI Embedded analytics architecture. This system integrates with SAP Fiori through iFrame embedding and Azure AD authentication pass-through.
We developed an Azure Data Factory pipeline that:
- Extracts data from SAP ERP,
- Pulls information from the MES system,
- Connects to the supply chain platform, and
- Accesses SAP BW.
This pipeline refreshes every 15 minutes. It loads data into an Azure SQL Database that uses an optimized star schema. Power BI datasets connect to this unified data layer in two ways:
- Directly from the Azure SQL Database.
- Through a data model that enhances performance.
- DirectQuery: for real-time metrics
- Import mode: for historical trend analysis
The dashboard suite featured 6 core views:
- Overall Equipment Effectiveness (OEE) by plant and production line
- Quality defect rate with drill-down to individual work orders
- Supply chain inventory levels with predictive reorder alerts
- Financial margin analysis by product line
- Workforce productivity metrics
- Executive summary comparing all 18 plants on standardized KPIs
Row-level security allowed plant managers to access only their specific facility data. Regional VPs could view data collected from multiple facilities.
Furthermore, alerting through Power Automate notified managers when KPIs exceeded set thresholds.
- If OEE fell below 85% on any production line, managers were alerted.
The Results
28% Faster Decision-Making
Time from issue detection to corrective action reduced from 2-3 days to same-shift response across all 18 plants
Real-Time KPI Visibility
15-minute data refresh replaced 2-3 day manual consolidation — plant managers had current data for the first time
18 Plants Unified
Single analytics platform replaced 4 fragmented systems across SAP ERP, MES, supply chain, and SAP BW
$3.2M Quality Cost Reduction
Early defect detection via real-time quality dashboards reduced scrap and rework costs by $3.2M in year one
4.2% OEE Improvement
Average OEE across 18 plants improved from 78.3% to 82.5% — worth $8.4M in additional production capacity
6-Month Deployment
Data pipeline, 6 dashboard suites, SAP Fiori integration, and rollout to all 18 plants completed in 6 months
Timeline:
6 months (data pipeline through plant floor deployment)
Tech Stack:
Power BI Embedded, Azure Data Factory, Azure SQL Database, SAP Fiori Integration, Power Automate, Row-Level Security, Azure AD, Azure API Management

Why Enterprise Results Require Experienced Partners
We examined six case studies to understand why enterprise Microsoft deployments succeed or fail. This pattern is not related to the technology itself. Microsoft's platform can meet all the needs of these organizations.
The key difference between success and failure lies in the partner's ability to manage non-technical challenges. These challenges include:
- Organizational politics
- Compliance requirements
- Resistance to change
- Dependencies on legacy systems
- Aggressive timelines set by leadership, who may not fully understand technical realities
Consider the healthcare case study. Three previous firms tried to migrate but failed. They used the same technology, SharePoint Online. However, our approach was different.
- We implemented a governance framework that classified PHI before migration, not after.
- Our change management team collaborated with clinical champions instead of issuing top-down mandates.
- We leveraged our experience with 50,000+ user environments to create realistic wave planning.
These capabilities come from performing this work hundreds of times in similar environments, not just from reading Microsoft documentation.
Compliance Expertise Is Not Optional
Every case study involved regulatory requirements — HIPAA, SOC 2, FedRAMP, FERPA, NERC CIP. A partner who treats compliance as an afterthought will create audit findings that cost more to remediate than the original project. Our compliance-first approach means security controls are designed into the architecture, not bolted on after deployment.
Change Management Determines Adoption
The Teams governance case study achieved 92% adoption because governance was designed to enable users, not restrict them. The Power BI deployment succeeded because training was role-specific, not generic. User adoption is the single largest determinant of project ROI, and it requires dedicated change management resources — not a one-hour training webinar at the end of the project.
Scale Introduces Nonlinear Complexity
Migrating 500 users is not the same as migrating 50,000 users at 100x the effort. At scale, every edge case multiplies, network bandwidth becomes a constraint, support ticket volumes spike, and wave planning becomes critical. Partners who have only worked with mid-market organizations underestimate enterprise complexity by 3-5x, leading to blown timelines and budgets.
Governance Frameworks Prevent Rework
Every case study included a governance framework deployed before or alongside the technical implementation. Organizations that skip governance end up paying 2-3x to remediate the sprawl, security gaps, and compliance violations that accumulate in an ungoverned environment. The university had 28,000 ungoverned Teams as proof of what happens without a framework.
Patterns Across Successful Enterprise Engagements
After analyzing hundreds of enterprise Microsoft deployments over 29 years, we have identified clear patterns that set successful projects apart from unsuccessful ones. These insights are not just theoretical best practices. They are lessons learned from real delivery experiences that influenced the outcomes in the case studies above.
Assessment Before Architecture
Every successful case study began with a formal assessment phase lasting 4-8 weeks. The financial services firm's report rationalization exercise eliminated 72% of Cognos reports before migration began, saving 4+ months of unnecessary work. The energy company's Azure Migrate assessment identified 12 servers that could not move to cloud, preventing a compliance violation that would have been discovered during audit.
Phased Rollout Over Big-Bang Deployment
All six engagements used phased rollout strategies. The healthcare system migrated by department criticality. The government agency deployed Exchange before SharePoint before Teams. Big-bang deployments at enterprise scale create concentrated risk, overwhelm support teams, and provide no opportunity to learn from early waves and adjust before later waves.
Executive Sponsorship With Accountability
Every successful engagement had an executive sponsor who participated in weekly steering committee meetings, removed organizational blockers, and held their own teams accountable for adoption. Engagements where the executive sponsor delegated to a mid-level manager consistently experienced timeline delays and lower adoption rates.
Metrics-Driven Validation
Each case study defined success metrics before the engagement began — not after. The healthcare system measured time-to-document-retrieval. The manufacturer tracked OEE improvement. The university measured support ticket volume. Without predefined metrics, there is no objective way to determine whether the investment delivered value.
Hypercare Is Not Optional
All six engagements included 60-90 day hypercare periods with dedicated support resources. The period immediately after go-live is when users form permanent habits. If they encounter friction and cannot get help within hours, they revert to workarounds that persist for years. Hypercare is where adoption is cemented or lost.

Frequently Asked Questions About Enterprise Microsoft Consulting
Common questions from CTOs, CIOs, and IT leaders evaluating Microsoft consulting partners for enterprise deployments.
What results do enterprises typically achieve with Microsoft consulting?
Enterprise Microsoft consulting engagements typically deliver measurable outcomes within 6-12 months. Based on our case studies, organizations achieve 30-40% productivity improvements from SharePoint and M365 migrations, $1-3M in annual cost savings from analytics platform consolidation, 90%+ user adoption rates with proper change management, and 25-35% infrastructure cost reductions from Azure cloud migrations. The key differentiator is working with an experienced partner who brings governance frameworks, compliance expertise, and proven methodologies rather than learning on the job.
How long does an enterprise SharePoint migration typically take?
Enterprise SharePoint migrations for organizations with 25,000-50,000+ users typically take 8-14 months from assessment through hypercare. The timeline breaks down as: discovery and planning (6-8 weeks), architecture and governance design (4-6 weeks), pilot migration with 500-1,000 users (4-6 weeks), phased production migration in waves of 5,000-10,000 users (12-20 weeks), and post-migration optimization and hypercare (8-12 weeks). Our Fortune 500 healthcare case study completed a 50,000-user migration in 11 months while maintaining HIPAA compliance throughout.
What is the typical ROI of a Power BI enterprise deployment?
Enterprise Power BI deployments that replace legacy BI platforms like Cognos, Business Objects, or Tableau Server typically achieve 150-measurable ROI within the first 18 months. Direct cost savings come from eliminated license fees ($500K-$2M annually for large organizations), reduced report development time (60-70% faster with Power BI), and decommissioned infrastructure. Indirect benefits include faster decision-making (20-30% improvement), self-service analytics reducing IT bottleneck by 40-60%, and improved data quality through centralized governance. Our financial services case study documented $2.1M in annual savings from replacing Cognos with Power BI across 8,000 analysts.
How do you ensure HIPAA compliance during a Microsoft deployment?
HIPAA-compliant Microsoft deployments require a layered approach: Microsoft 365 E5 licensing with signed Business Associate Agreement (BAA), Azure Private Link for all data connections, Microsoft Purview sensitivity labels and DLP policies for PHI classification, Conditional Access policies enforcing MFA and compliant device requirements, audit logging with 365-day retention in Microsoft Sentinel, and role-based access control with quarterly access reviews. Our healthcare case study maintained zero HIPAA violations during an 11-month migration by implementing these controls before migrating a single user.
What should enterprises look for in a Microsoft consulting partner?
Enterprises should evaluate Microsoft consulting partners on five criteria: (1) Verifiable case studies with specific metrics, not vague claims — ask for client references in your industry. (2) Microsoft Solutions Partner designations across relevant workloads (Data & AI, Modern Work, Infrastructure, Security). (3) Compliance expertise proven through regulated industry deployments (HIPAA, FedRAMP, SOC 2). (4) A defined methodology with governance frameworks, not ad-hoc project management. (5) Post-deployment support capabilities including managed services and 24/7 monitoring. EPC Group meets all five criteria with 29 years of enterprise Microsoft consulting experience.
How do enterprises achieve high adoption rates for Microsoft 365?
Achieving 90%+ adoption rates for Microsoft 365 requires a structured change management program that starts before deployment. Key elements include: executive sponsorship with visible leadership participation, champion networks of 50-100 power users per 5,000 employees, role-based training tailored to actual workflows (not generic Microsoft tutorials), governance policies that enable rather than restrict users, adoption dashboards tracking active usage by department, and a 90-day reinforcement plan with gamification elements. Our higher education case study achieved 92% adoption across 40,000 students and faculty using this approach.
What is the cost difference between in-house Microsoft implementation vs. consulting?
In-house Microsoft implementations typically cost 40-60% more than partner-led engagements when accounting for total cost. A 50,000-user SharePoint migration done in-house requires hiring 8-12 specialists at $150K-$200K each ($1.2M-$2.4M annually), takes 18-24 months vs. 10-14 months with a partner, and carries significant risk of architectural mistakes that cost $500K+ to remediate. A consulting partner brings proven frameworks, certified specialists, and lessons learned from dozens of similar engagements. The faster timeline alone typically saves $500K-$1M in productivity costs. EPC Group offers fixed-fee engagements that provide cost certainty absent from in-house projects.
Can Microsoft consulting partners help with FedRAMP compliance?
Yes, experienced Microsoft consulting partners can guide federal agencies and government contractors through FedRAMP-aligned Microsoft deployments. This includes deploying in Microsoft Government Cloud (GCC, GCC High, or DoD), implementing NIST 800-53 controls mapped to Microsoft 365 and Azure capabilities, configuring Conditional Access and Intune policies meeting FedRAMP Moderate or High baselines, establishing continuous monitoring with Microsoft Sentinel and Defender for Cloud, and maintaining documentation required for ATO (Authority to Operate). Our federal agency case study achieved FedRAMP-aligned consulting expertise work for a 25,000-user M365 deployment with zero security incidents during the 9-month rollout.
