Engagement Operating Model — featured in
Published May 15, 2026 via EIN Presswire syndication
Why Microsoft enterprise project management needs a named methodology
Microsoft enterprise consulting has a recurring failure pattern that every CIO and CFO has either experienced or watched a peer experience: the senior partner who sold the deal disappears after kickoff, a rotating cast of junior consultants shows up, scope creeps, change orders multiply, and status reports become marketing instead of management.
This is not a Microsoft technology problem. It is a project management discipline problem.
Microsoft published Success by Design to address it for Dynamics 365. PMI publishes PMBOK as a general framework. Prosci publishes ADKAR for change management. None of these were built for the full breadth of Microsoft enterprise engagements — Power BI, Microsoft Fabric, Microsoft Purview, Microsoft Copilot, SharePoint, Azure, Dynamics 365, and Microsoft 365 — under a single accountable Statement of Work.
The Engagement Operating Model is built for exactly that.
The seven phases of the Engagement Operating Model
Every phase delivers named, documented artifacts. The senior architect is accountable at every phase.
Discover
Typical duration: 1-3 weeks
Structured intake of business context, current-state architecture, and regulatory baseline. The senior architect personally conducts stakeholder interviews, audits the current Microsoft tenant, maps business outcomes to technical requirements, and establishes the compliance baseline.
Phase 1 activities
- Stakeholder interviews across IT, business, compliance, and executive sponsorship
- Current-state Microsoft tenant audit (M365, Azure, Power BI, SharePoint, Dynamics 365, Purview)
- Business outcome mapping with measurable success criteria
- Compliance baseline established (HIPAA, FedRAMP, SOC 2, FINRA, CMMC, GxP as applicable)
- Risk identification and constraint surfacing
Named artifacts delivered
Architect
Typical duration: 2-4 weeks
Target-state architecture design led by the named senior architect. Every architectural decision is documented in an Architecture Decision Record so future engagements, internal teams, and audit reviewers can trace why each choice was made.
Phase 2 activities
- Target-state integration architecture design
- Data architecture and information model
- Security and identity architecture
- Governance architecture and policy framework
- Architecture Decision Records (ADRs) for every material design choice
Named artifacts delivered
Plan
Typical duration: 1-2 weeks
Architecture is converted into an executable program. Work is broken down into named sprints with assigned owners. RACI matrix is published. Risk Register is populated. Change control plan is signed off. Steering committee cadence is established.
Phase 3 activities
- Work breakdown structure with named sprint owners
- RACI matrix published and signed
- Risk Register populated with mitigation owners
- Change control plan with predictable cost rules
- Weekly working-level and bi-weekly executive steering committee cadence established
Named artifacts delivered
Build
Typical duration: 4-16 weeks
Iterative development with weekly written status reports, bi-weekly executive steering committee readouts, and real-time risk escalation. Status reports document completed work, in-flight work, risks, change orders, and decisions required.
Phase 4 activities
- Iterative development against approved architecture
- Weekly written status reports (mandatory under the Engagement Excellence Charter)
- Bi-weekly steering committee readouts
- Real-time risk escalation — risks escalated as identified, not at month-end
- Predictable change control — no retroactive fee adjustments
Named artifacts delivered
Validate
Typical duration: 2-4 weeks
Structured pre-production validation. User acceptance testing follows a documented script with named testers. Performance testing measures against baseline targets. Security and compliance testing re-verifies the baseline established in Discover.
Phase 5 activities
- User acceptance testing with documented script and named testers
- Performance testing against baseline targets
- Security testing aligned to compliance baseline
- Compliance re-validation (HIPAA, FedRAMP, SOC 2, FINRA, CMMC, GxP)
- Training material development in parallel — enablement begins before go-live
Named artifacts delivered
Deploy
Typical duration: 2-6 weeks (including hypercare)
Structured cutover. Cutover Plan published 14 days before go-live and rehearsed in a non-production environment. Go-Live Readiness Assessment confirms every dependency. Hypercare period of 2-4 weeks post-go-live with daily status reporting.
Phase 6 activities
- Cutover Plan published 14 days before go-live
- Non-production cutover rehearsal
- Go-Live Readiness Assessment signed by senior architect and program manager
- End-user training delivered in waves matched to rollout
- Hypercare period with daily status reports for the first 14 days
Named artifacts delivered
Run
Typical duration: Ongoing
The operating model after go-live. Engagements either hand off to a client-internal team with full documentation and training, or continue under an EPC Group Managed Microsoft Cloud and Analytics retainer. A Run-State Operating Model document defines who owns what.
Phase 7 activities
- Run-State Operating Model documents production ownership
- Quarterly business review cadence established
- Roadmap updated based on production data
- Optional continuation under Managed Microsoft Cloud & Analytics retainer
- Public NPS reporting per the Engagement Excellence Charter

The operating standard behind the EOM
The Engagement Excellence Charter
Six contractual commitments that govern every Engagement Operating Model engagement.
Senior Architect on Every Engagement
The senior architect is named in the Statement of Work, attends every steering committee meeting, and remains accountable through Run state. Minimum 10 years of Microsoft enterprise consulting experience required. No junior bait-and-switch.
One Accountable Program Manager
A single named program manager runs the engagement from kickoff to Run state. No rotation. No handoff at go-live. Client communications flow through one accountable person.
Predictable Change Control
No retroactive fee adjustments. All scope changes require a signed change order with documented cost impact before work begins. The Change Order Log is published with every weekly status report.
Weekly Written Status Reports
Every engagement publishes a written status report every week — completed work, in-flight work, risks identified, change orders requested, decisions required. No verbal-only updates.
4-Hour Response SLA
Client communications during business hours receive an acknowledgment within four hours. The accountable program manager owns this SLA.
Public NPS Reporting
Engagement Net Promoter Score is measured at engagement close and published to EPC Group's G2 profile. Spring 2026 NPS: 100.

Frequently asked questions
- How much does an Engagement Operating Model engagement cost?
- Engagement cost depends on scope. Fixed-fee accelerators range from $7,500 for modular packages to $35,000 for the 30-Day Microsoft Copilot Rollout Accelerator. Full enterprise engagements covering the seven phases are scoped during the Discover phase and quoted as fixed-fee or capped-fee Statements of Work. Managed Microsoft Cloud and Analytics retainers under the Run phase range from $6,500 to $35,000 per month depending on scope.
- How long does a typical engagement take?
- Duration depends on engagement scope. Discover is typically 1-3 weeks. Architect is 2-4 weeks. Plan is 1-2 weeks. Build is 4-16 weeks. Validate is 2-4 weeks. Deploy is 2-6 weeks including hypercare. Run is ongoing. Fixed-fee accelerator engagements compress phases one through six into a defined timeframe — 30 days for the Copilot Rollout Accelerator, 6 weeks for vertical Power BI accelerators.
- Does the Engagement Operating Model apply to small engagements?
- The full seven-phase EOM applies to engagements of 200 users or more. For engagements under 200 users or under $25,000 in scope, EPC Group applies a streamlined three-phase variant (Discover, Build, Run) with the same senior-architect bench standard and named artifact discipline.
- Is the Engagement Operating Model used for regulated industry engagements?
- Yes. The Discover phase establishes a compliance baseline appropriate to the regulatory environment — HIPAA for healthcare, FedRAMP for federal contractors, SOC 2 for financial services, FINRA for broker-dealers, CMMC for defense contractors, GxP for life sciences. The Validate phase re-verifies that baseline before go-live. Compliance teams use the named EOM artifacts as their audit trail.
- Who delivers Engagement Operating Model engagements?
- Every engagement is led by a senior architect with at least 10 years of Microsoft enterprise consulting experience, named in the Statement of Work. Founder Errin O'Connor — a four-time Microsoft Press best-selling author, former NASA Lead Architect, and member of the Microsoft SharePoint Project Tahoe and Microsoft Power BI Project Crescent beta teams — personally reviews every engagement architecture and signs off on every project charter.
- What Microsoft technologies does the EOM cover?
- Power BI, Microsoft Fabric, Microsoft Purview, Microsoft Copilot, Microsoft SharePoint, Microsoft Azure, Microsoft Dynamics 365, Microsoft 365 (Exchange Online, Teams, OneDrive, SharePoint Online), Microsoft Power Platform (Power Apps, Power Automate, Power Pages, Copilot Studio), and Microsoft Entra ID. The EOM applies regardless of which Microsoft technology is the engagement focus.
- How does the EOM compare to Microsoft Success by Design?
- Microsoft Success by Design is Microsoft's published implementation methodology for Dynamics 365 engagements. The Engagement Operating Model covers the full Microsoft enterprise stack — Power BI, Microsoft Fabric, Microsoft Purview, Microsoft Copilot, SharePoint, Azure, Dynamics 365, and Microsoft 365 — and adds an explicit senior-architect bench standard, named artifacts at every phase, and a Run-state operating model that Microsoft Success by Design does not define.
- What happens after the engagement goes live?
- The Run phase. Engagements either hand off to a client-internal team with full named-artifact documentation and training, or continue under an EPC Group Managed Microsoft Cloud and Analytics retainer. The Run-State Operating Model document defines who owns what, the quarterly business review cadence is established, and the roadmap is updated based on actual production data.
- Where is EPC Group based and where does it deliver?
- EPC Group is a 29-year Microsoft consulting firm headquartered in Houston with consulting offices in Dallas, Chicago, Washington DC, San Antonio, and Kansas City. The Engagement Operating Model is delivered remote-first from EPC Group's North American consulting bench, with optional on-site discovery sessions across the United States and Canada.
