Shared Services Design

Shared services work when the operating model is designed right from the start. ClarityArc defines the service scope, governance, sourcing model, and capability boundaries that determine whether a shared services function actually reduces cost and improves quality — or just centralizes the problem.

When Organizations Need This
The same function — finance, HR, IT, procurement — is being performed independently across multiple business units with no standardization and significant cost duplication
A merger or acquisition has created parallel organizational functions and leadership needs a rationalized model for the combined entity
A shared services function already exists but performance is poor, adoption is low, or business units are routing around it with their own resources
The organization is planning a transformation or outsourcing initiative and needs clarity on which capabilities to centralize, retain locally, or source externally

Why Most Shared Services Fail

Shared services are not a cost-cutting measure. They are an operating model decision — and most organizations treat them like the former.

The typical shared services failure starts with centralizing a function before defining what it is actually supposed to do, who it serves, and how its performance will be measured. Without clear capability boundaries, service agreements, and a governance model that gives business units meaningful recourse, shared services becomes a cost center with no accountability — and business units route around it at the first opportunity.

ClarityArc designs shared services operating models grounded in business architecture principles: defined capability scope, clear service levels, a governance structure that balances standardization with business unit flexibility, and a sourcing model matched to the organization's actual scale and risk profile.

The questions that determine success
Scope
Which capabilities belong in shared services and which must remain local? What is the minimum viable scope that justifies the model?
Governance
Who owns service performance? What recourse do business units have? How are disputes resolved without escalating to executive leadership?
Sourcing
Internal, outsourced, or hybrid? Which functions benefit from scale and which require organizational context that an external provider cannot replicate?
Transition
What is the sequencing, staffing, and change management plan that gets the organization from its current state to the target model without operational disruption?
Choosing the Right Model

Three models. One right answer for your organization.

The first decision in any shared services design engagement is choosing the right structural model. ClarityArc evaluates three options against your organization's scale, risk profile, and strategic priorities before any design work begins.

Shared Services Center

Dedicated Internal Function

A centralized internal unit that delivers defined services to business units under formal service level agreements. The SSC owns its capabilities, headcount, and technology — with costs recovered through a chargeback or allocation model. Best suited to organizations with sufficient scale to justify a dedicated function and strong executive will to standardize.

Best fit when
Organization operates across multiple business units or geographies with genuinely duplicated functions
Leadership is prepared to enforce standardization even under business unit resistance
Transaction volume justifies dedicated headcount and technology investment
Centre of Excellence

Standards & Capability Hub

A central function that owns standards, methodology, and specialized capability — but does not deliver transactional services. Business units retain local execution while drawing on the CoE for expertise, governance, and quality assurance. Better suited to knowledge-intensive functions where standardization of practice matters more than standardization of delivery.

Best fit when
The function involves significant judgment and context that cannot be standardized away
Business units have legitimate reasons to retain local delivery capacity
The goal is consistency of outcome rather than consolidation of headcount
Hybrid Model

Centralized Core, Local Flex

A tiered model where high-volume, standardizable services are centralized while functions requiring local knowledge or relationship remain distributed. The most common model for mid-market organizations that cannot justify a full SSC but need more consistency than a CoE alone provides. Requires careful boundary definition to avoid the worst of both models.

Best fit when
Functions split naturally between transactional volume (centralizable) and advisory services (local)
Organization wants to capture cost reduction without disrupting high-value local relationships
Full centralization is politically or operationally not feasible in the near term
How We Work

Four steps to a shared services model your organization will actually use.

ClarityArc's shared services design methodology moves from scope definition through operating model design, governance, and transition planning — in that order. Skipping any step is the most common reason shared services functions underperform.

01 Step One

Capability Scoping & Current-State Assessment

A structured assessment of which capabilities are candidates for shared services — evaluated against current cost, performance, standardizability, and strategic fit. Includes a current-state view of where duplication exists, what it costs, and what the business case for consolidation actually looks like before any model is chosen.

02 Step Two

Model Selection & Operating Model Design

Selection of the appropriate service model — SSC, CoE, or hybrid — based on scope, scale, and organizational readiness. Full operating model design covering organizational structure, service catalog, SLA framework, performance metrics, chargeback or allocation methodology, and technology requirements.

03 Step Three

Governance Framework & Service Agreements

A governance model that gives shared services clear accountability without removing meaningful recourse from business units. Includes escalation paths, dispute resolution, performance review cadences, and the decision rights framework that keeps the function from becoming either a black box or a political battleground.

04 Step Four

Transition Roadmap & Readiness Planning

A sequenced, risk-managed transition plan covering staffing, technology, process migration, and change management. Designed to move the organization from current state to the target model without creating service disruption during the transition — with defined milestones and go/no-go criteria at each phase.

What You Receive

Four deliverables. One complete operating model.

Every shared services design engagement produces a complete set of outputs — from business case through implementation roadmap — that your leadership and HR or finance teams can carry directly into execution.

Deliverable 01

Shared Services Business Case

A structured cost-benefit analysis that quantifies the current cost of duplication, the investment required to stand up the shared services model, the projected savings, and the break-even timeline — with scenario analysis across the model options considered.

Deliverable 02

Operating Model & Service Catalog

A complete operating model for the shared services function — covering organizational structure, reporting lines, headcount model, service catalog with defined scope for each service, SLA framework, performance metrics, and chargeback or allocation methodology.

Deliverable 03

Governance Framework

The governance model that keeps the shared services function accountable — including decision rights, escalation paths, service review cadences, dispute resolution process, and the performance management framework that links service delivery to outcomes the business actually cares about.

Deliverable 04

Transition Roadmap

A phased implementation plan that sequences the transition from current state to target model — covering staffing and recruitment, technology enablement, process migration, change management, and the communication plan for business units affected by the transition.

The Difference It Makes

Before and after a well-designed shared services model.

The gap between a shared services function that captures its projected benefits and one that becomes a source of organizational friction almost always traces back to how the operating model was designed — not how it was executed.

Without a Designed Model
Centralization creates a function with no defined scope, unclear accountability, and no meaningful SLAs — business units complain but have no recourse
Chargeback model feels arbitrary to business units — shared services costs are opaque and resentment builds
Business units route around shared services with shadow resources, undercutting both the cost savings and the rationale for the function
Governance escalates every significant dispute to executive leadership because no lower-level resolution path exists
Transition rushed without change management — business unit leaders resist adoption and the function never reaches its intended scale
With a ClarityArc-Designed Model
Service scope, SLAs, and performance metrics defined before the function launches — business units know exactly what to expect and hold the function to it
Chargeback model built on transparent cost attribution — business units understand what they are paying for and why
Adoption supported by governance that gives business units real recourse — reducing the incentive to route around the function
Escalation paths and dispute resolution defined at launch — executive leadership is not the first line of resolution
Transition sequenced and change-managed so business units are prepared before the function goes live — not surprised after
What Separates Good from Great

Most shared services models are designed by HR or finance. The best ones are designed as operating models.

Dimension Typical Approach ClarityArc Approach
Scope Definition Everything in the function is centralized by default — scope is defined by organizational chart, not by capability analysis Scope defined through structured capability assessment — only capabilities that are genuinely standardizable and scalable are centralized
Service Levels SLAs defined as aspirational targets with no consequence for underperformance — business units have no recourse when service is poor SLAs defined with business unit input, tied to performance metrics, and backed by a governance model with real escalation paths and consequences
Cost Recovery Chargeback model built on allocation percentages that business units cannot trace to actual service consumption — creates resentment Cost recovery model designed for transparency — business units can see what they are consuming and why it costs what it costs
Sourcing Internal vs. outsourced decision made based on cost alone — organizational context, quality risk, and transition complexity underweighted Sourcing decision evaluated across cost, quality, risk, and transition complexity — with a hybrid model considered when appropriate
Transition Transition treated as an IT and HR project — business unit change management deprioritized until adoption problems emerge Transition designed as an organizational change program with structured communication, stakeholder engagement, and phased go-live milestones
Common Questions

What organizations ask before starting a shared services design engagement.

We already have a shared services function. Can you help fix it rather than redesign it from scratch?
Yes — and this is one of the most common engagements we run. Organizations with underperforming shared services functions typically have identifiable root causes: scope that was too broad from the start, SLAs that were never enforced, a chargeback model that business units do not trust, or a governance structure that left too many disputes unresolved. ClarityArc conducts a structured diagnostic of the existing function and targets the redesign effort at the specific failure points rather than rebuilding everything from the ground up.
How do you handle the political dynamics of shared services — particularly when business units feel they are losing control?
Business unit resistance to shared services is almost always rational — it reflects a genuine history of centralization that reduced service quality and left them with no recourse. Our design approach addresses this directly: service scope is defined with business unit input, SLAs are set at levels business units actually need rather than what is operationally convenient for the center, and governance gives business units real escalation paths rather than theatrical ones. When business units see that the model has accountability built into it, resistance typically shifts from opposition to negotiation — which is a much more productive starting point.
What functions are best suited to shared services in mid-market organizations?
In mid-market organizations, the strongest shared services candidates are transactional finance (accounts payable, accounts receivable, payroll), IT service desk and infrastructure support, procurement for non-strategic categories, and HR administration. Functions that involve significant business unit-specific judgment — strategic HR, business partnering, category management for strategic spend — are generally better suited to a Centre of Excellence or hybrid model. The right answer always depends on your specific scale, organizational complexity, and how standardized your processes actually are across units. See our capability mapping page for context on how we assess standardizability at the capability level.
How long does a shared services design engagement take?
Most shared services design engagements complete in ten to sixteen weeks — covering current-state assessment, model selection, operating model design, governance framework, and transition roadmap. The business case work runs in parallel with the design work. Engagements that include a detailed technology assessment or sourcing evaluation typically run at the longer end of that range. We structure the engagement to produce the business case and model selection recommendation within the first four to six weeks so leadership can make a go/no-go decision before the full design investment is committed.
