An SAP S/4HANA Center of Excellence (COE) is a permanent governance, planning, and continuous improvement function, not a temporary support desk. It is responsible for change control, release management, architecture oversight, and continuous improvement across the SAP landscape. We have seen companies gain tremendous value from well-organized and well-supported SAP CoEs. Conversely, we have seen many organizations that do not invest in or support their CoEs to get suboptimal results. Successful Organizations build one by chartering it with executive sponsorship, staffing a three-tier governance structure, and funding it as an ongoing operating cost rather than a post-go-live project. According to SAPinsider’s 2025 RISE with SAP benchmark study of 122 SAP professionals, only 62% of organizations already running SAP Cloud ERP Private were actively following the shared responsibility model, and 32% of all respondents said they were aware of the model but not following it rigorously.
Key Takeaways
- It is difficult to maximize the value you gain from SAP solely through the initial implementation. The true value that is extracted comes from exploring and improving the system post go-live.
- An empowered CoE that is continuously improving and extending usage and improving adoption is worth much more than the initial go-live.
- An SAP S/4HANA COE is a permanent operating function that owns governance, change control, release management, and architecture oversight, not a renamed support desk or a 90-to-180-day hypercare team.
- A durable COE rests on four components: a governance charter, an organizational structure with defined roles, unified change/incident/release processes, and a connected technology system of record.
- SAPinsider’s 2025 RISE with SAP benchmark study found 62% of organizations running SAP Cloud ERP Private follow the shared responsibility model rigorously, while another 32% are aware of it but don’t follow it closely.
- The Design Authority, not the Technical SME, should approve clean-core exceptions, because combining both roles in one person creates a conflict of interest.
- Organizations already live on SAP S/4HANA should run an inventory and remediation sprint before naming process owners or building a demand backlog.
- A COE needs a funding model, either a fixed annual budget or a chargeback model, that survives past the first fiscal year, or it reverts to project-style, on-again-off-again support.
What Is an SAP S/4HANA Center of Excellence?
An SAP S/4HANA Center of Excellence (COE) is a permanent operating function responsible for governance, change control, release management, architecture oversight, and continuous improvement for as long as the SAP landscape is in production. It is not a project team, and it has no end date.
Organizations rarely reject the idea of a COE. What breaks is the execution (and often the funding): Configuration drift accumulates as teams patch around issues instead of addressing root causes. Customizations expand without architectural review. The consultants who understood earlier design decisions roll off the project. Support requests get handled inconsistently because no single group owns the operating model. The other issue is that sometimes the CoE is viewed as a nice-to-have cost center that will be sacrificed at the next budget cut. This is an unfortunate pattern we have seen over the years with the usual expected results.
A year or two after go-live, the business case that justified the program can be underperforming while accountability is no longer clear. Building an SAP S/4HANA COE is the structural response to that erosion.
Why Do Many SAP S/4HANA COEs Fail or Stall?
Most COEs fail for one of three reasons: no executive sponsorship, unclear scope, minimal budget, or being treated as a project instead of a permanent function.
No Executive Sponsorship
A COE that reports through a mid-level IT manager has no standing to enforce a change freeze, deny a custom development request, or reallocate budget from an overspending business unit. Without visible sponsorship from the CIO or a business executive, the COE is advisory rather than authoritative, and its recommendations get overridden as soon as competing priorities emerge.
Unclear Scope
Some COEs stop at the S/4HANA core, leaving SAP Business Technology Platform (BTP) extensions, integrations, analytics, and satellite applications outside their remit. That is exactly where configuration drift and shadow IT tend to emerge.
Treated as a Project, Not a Function
Program teams often fund a “hypercare COE” for 90 or 180 days after go-live, then disband it once the project budget closes, mistaking stabilization for governance. A COE with an end date is not a COE. It is an extended project.
What Are the Four Components of an SAP S/4HANA COE?
A durable SAP S/4HANA COE rests on four components: governance, people, process, and technology. Together, they define the operating model mature SAP organizations use to govern S/4HANA after implementation.
Governance Model and Charter
The COE charter is a short document, typically one to two pages, approved by the executive sponsor. It defines the outcomes the COE owns (reliability, process standardization, adoption, compliant change, release management, data quality), its scope across S/4HANA core and connected systems, and its decision rights: what the COE recommends, approves, executes or escalates.
If the charter does not give the COE authority to stop or redirect noncompliant changes, it is documenting governance rather than governing.
SAP’s own Customer Center of Excellence framework (CCoE) is a useful reference for governance scope and decision rights, though most organizations adapt it to their own landscape and regulatory requirements.
Organizational Structure and Roles
A three-tier governance structure gives the COE both strategic direction and day-to-day decision-making capacity, addressing the ownership gap that drives so much post-go-live risk.
Three-Tier Governance Structure
Strategic direction at the top, day-to-day decision-making capacity below it.
Shading is ordinal, not decorative: darker marks broader strategic authority (Tier 1), lighter marks closer day-to-day operating scope (Tier 3).
Beneath that structure, a RACI clarifies who does what day-to-day. The Design Authority, not the Technical SME, approves clean-core exceptions. SMEs evaluate the technical impact; the Design Authority determines whether the deviation aligns with enterprise architecture standards. Combining both responsibilities in one role creates a conflict of interest.
SAP S/4HANA COE — RACI Matrix
Who does what for the core governance activities beneath the three-tier structure.
| Activity | COE Lead | Process Owner | Technical SME | Business Liaison | Design Authority |
|---|---|---|---|---|---|
| Demand intake and prioritization | A | R | C | C | I |
| Architecture and clean-core exception review | C | I | R | I | A |
| Incident triage and resolution | I | A | R | C | I |
| Release planning | A | C | R | C | C |
| Benefit realization reporting | R | A | I | C | I |
Only one role should hold “Accountable” per activity — combining Accountable and Responsible in a single seat is the conflict of interest this matrix is designed to prevent.
Centralized vs. Federated: How Should a COE Be Organized?
The staffing model above can run three ways.
- Centralized: every role reports through a single line, giving the most consistency and control at the cost of proximity to individual business units.
- Federated: technical SMEs sit inside regional or business-unit pods and report to the COE lead on a dotted line, trading some consistency for faster response and closer business alignment.
- Hybrid: governance, standards, and architecture stay centralized, while delivery capacity federates to stay close to the business. Most large, multi-entity organizations land here.
How Should Change, Incident and Release Management Work?
The COE’s processes cover three areas: change control (demand intake, impact analysis, architecture review, testing, business acceptance), incident and problem management (triage and root-cause elimination, not just ticket closure), and release management (a predictable calendar for SAP updates, regression testing and rollout communication).
These run as one workflow, not three separate ones. Demand enters through a common intake process, moves through architecture review and testing, and concludes with production release and post-deployment review. Splitting change, incident, and release management into uncoordinated functions is what lets configuration drift accumulate unnoticed.
What Technology and Tooling Does a COE Need?
Governance processes need a system of record, or approvals, documentation, and improvement initiatives end up scattered across platforms nobody owns end-to-end. A typical COE tooling landscape includes:
- SAP Cloud ALM for cloud-first landscapes, or SAP Solution Manager for existing on-premises investments
- An ITSM platform such as ServiceNow
- SAP Change Request Management (ChaRM) or equivalent transport controls
- Documentation repositories
The objective is to connect these systems, not replace them, so approvals and metrics stay traceable across all of them.
Who Should Staff an SAP S/4HANA COE?
CIOs and enterprise architects should plan staffing around end-to-end processes rather than individual modules. Local fixes made in isolation are a leading cause of downstream configuration drift.
Core Roles
- COE lead: owns the charter, the backlog, and reporting to the steering committee.
- Global process owners: accountable for finance, order-to-cash, procure-to-pay, plan-to-produce, or other end-to-end processes.
- Functional and technical SMEs: configuration, integration, and Basis expertise tied to specific process areas.
- Business liaisons or key users: the connective tissue between the COE and the operating business units.
- Security and controls lead: segregation-of-duties, authorizations, and audit readiness.
What Should You Keep In-House vs. Outsource?
The build-versus-outsource decision usually comes down to who is accountable if something goes wrong, not who is cheapest to staff.

Outsourcing execution does not outsource accountability — a partner should document changes against the same clean-core and change-control standards the internal COE uses.
Outsourcing execution does not outsource accountability. A partner team can deliver level-2/3 support or testing capacity well, but the risk to manage is accountability drift, where a partner makes changes the internal COE can no longer fully explain or defend during an audit. The mitigation is contractual, not aspirational: require the partner to document every change against the same clean-core and change-control standards the internal team uses, not a parallel set the partner controls.
How Should You Fund an SAP S/4HANA COE?
A COE needs a funding model that survives beyond the first fiscal year, or it reverts to project-style, on-again-off-again support, the same pattern that produces post-go-live value erosion.
Two funding models are common:
- A fixed annual operating budget tied to the steering committee’s approved scope. Simpler to run, but needs a strong sponsor to defend it at budget time.
- A chargeback model, where business units fund COE capacity in proportion to their usage. Sharpens prioritization discipline, but adds administrative overhead.
Either way, frame the funding request around the post-go-live support model it replaces, not the project budget it descends from. Boards typically find it easier to approve run-state operating costs than a line item that still resembles a project extension two years after go-live.
What KPIs Should the COE Report?
The COE lead should report a small set of metrics the steering committee will actually read. Only a third of live SAP organizations run regular monitoring and auditing today, according to the SAPinsider data cited earlier, which is worth stating plainly in the budget request.
- Mean time to restore for critical incidents
- Percentage of changes delivered using approved standard or clean-core-compliant approaches
- Number and age of approved core exceptions (a proxy for clean-core discipline)
- Percentage of incidents traced to known problems or root causes, not just closed
- Lead time from approved demand to production
- Business outcomes tied to specific enhancements (cycle-time reduction, error-rate reduction, adoption)
How Do You Build a COE in Phases?
A COE built in a single big-bang launch tends to collapse under its own governance overhead before it delivers anything. A durable SAP S/4HANA COE instead moves through three deliberate stages.
How a COE Matures: Three Stages
A durable COE moves through deliberate stages rather than a single big-bang launch.
Organizations already live on S/4HANA add an inventory and remediation sprint in front of the Foundational stage before naming process owners or building a demand backlog.
SAP’s Customer COE accreditation process is one option for external benchmarking once the foundational stage is complete, giving the steering committee an outside reference point rather than relying solely on internal self-assessment.
What Should You Do Differently If You’re Already Live?
The phased approach above assumes a build that starts at go-live. Most organizations reading this are two or three years past go-live, running an informal support team that has absorbed COE-like duties without the charter, budget or authority to go with them, on a landscape with undocumented customizations and configuration decisions no one can explain.
Remediating custom code is one of the top obstacles organizations report during and after their SAP Cloud ERP transition, according to the SAPinsider data cited earlier, and it does not go away on its own once a system is live.
For a retrofit, add an inventory and remediation sprint in front of the Foundational stage, before naming process owners or standing up a demand backlog:
- Catalog existing customizations against the clean-core standard.
- Identify where configuration has drifted from documented design.
- Document who currently owns each process area, formally or informally.
- Classify each customization as retire, remediate or retain-with-justification.
- Establish baseline KPIs from the metrics above before claiming any improvement.
- Bring the completed inventory to the executive sponsor as part of the charter conversation.
Skipping this step means the COE inherits a backlog it cannot explain, which undermines its credibility with the steering committee in month one.
Where Does a Platform Like LeapGreat Hub Fit?
The framework above only works if the organization can execute it consistently, which requires a system of record for demand, decisions, documentation, and continuous improvement, not governance scattered across a ticketing tool, a wiki, and a spreadsheet only the COE lead updates.
LeapGreat Hub is designed to support this operating model, not replace it. It centralizes demand intake and escalation so the RACI above maps to a real workflow instead of an email thread, keeps configuration and process documentation in a searchable knowledge base, and tracks continuous improvement initiatives against the KPIs a steering committee is asking for.
Most organizations already run some combination of SAP Solution Manager or SAP Cloud ALM, ChaRM, an ITSM platform such as ServiceNow, and separate documentation repositories. LeapGreat Hub is meant to orchestrate those systems, not duplicate them. For a COE moving from the foundational to the managed stage, that consolidation often determines whether the reporting cadence to the executive sponsor actually holds.
What Should CIOs Do in the Next 90 Days?
A COE should not be the final step of an SAP transformation. It should be the operating model that keeps the transformation delivering value after the project team leaves, with named roles, a clear RACI, funded processes, and a phased maturity path standing in for the accountability a go-live date alone cannot provide.
For CIOs and enterprise architects, the next 90 days come down to three moves:
- Assess where the current support model already resembles a COE, and where it doesn’t.
- Establish the charter, decision rights, and roles that formalize it.
- Operationalize the processes and tooling that make it repeatable.
