How to Design Shared Services, Centers of Excellence, and Business Partners

Introduction: The Evolving HR Delivery Model Landscape

As organizations navigate rapid business transformation, global competition, and digital disruption, the Human Resources function has evolved beyond traditional administrative roles into a strategic partner driving organizational capability and performance. This shift demands an operating model that delivers HR services efficiently, consistently, and with strategic impact.

The triad of Shared Services, Centers of Excellence (CoEs), and HR Business Partners (HRBPs) represents the dominant framework for HR operating model design worldwide. However, successful implementation is not merely about adopting these components, but about designing their structure, roles, and interactions thoughtfully to maximize value and alignment.

This guide will provide HR leaders and professionals a comprehensive framework for designing these elements effectively — addressing operating model options, role clarity, handoffs, and governance for strategic alignment and service excellence.

 

1. Operating Model Options for HR Delivery

The foundational decision in HR operating model design is how to structure the delivery of services across transactional, specialist, and strategic activities. The three primary models are centralized, federated, and hybrid.

 

1.1 Centralized HR Operating Model

Centralization consolidates HR functions into a single, unified entity. It often involves:

  • A Shared Services center handling all transactional HR activities
  • Centralized CoEs providing specialized expertise and developing global policies and programs
  • HRBPs aligned under central HR leadership but embedded strategically with business units for partnership

 

Benefits of Centralization

  • Cost efficiency through economies of scale and reduced duplication
  • Consistency in policy application, data integrity, and compliance
  • Improved governance with easier oversight and process control
  • Technology leverage, enabling integrated HR information systems and automation

 

Challenges and Mitigation

  • Potential perceived disconnect between HR and business units — mitigated by embedding HRBPs with strong business acumen and influence
  • Risk of bureaucracy and slower responsiveness — countered by empowering HRBPs and flexible service design
  • Scalability limits if one-size-fits-all approach is applied without flexibility

 

Real-World Example

A global consumer packaged goods company centralized its payroll, benefits, and recruitment Shared Services in two hubs, with CoEs leading global talent management strategies. HRBPs were embedded in regional business units but reported into central HR, balancing efficiency and proximity.

 

1.2 Federated HR Operating Model

Federation disperses HR responsibilities, situating HR capabilities within individual business units, regions, or subsidiaries. In this model:

  • Each business unit may have its own HR Shared Services-like function
  • CoEs may be duplicated or loosely connected, tailored by unit needs
  • HRBPs are embedded within units with greater autonomy

 

Benefits of Federation

  • Close alignment with specific business strategies, culture, and market dynamics
  • Enhanced customization and agility in HR programs
  • Greater local ownership and accountability

 

Challenges and Mitigation

  • Risk of redundant resources and higher costs
  • Inconsistent employee experience and HR policies
  • Complexity in cross-unit coordination

 

Real-World Example

A multinational conglomerate with diverse business portfolios maintained separate HR teams for each unit, optimizing for responsiveness but facing challenges with policy harmonization.

 

1.3 Hybrid HR Operating Model

The hybrid model blends centralization and federation, balancing standardization with local responsiveness. Typically:

  • Shared Services handle global transactional HR activities
  • CoEs provide specialist expertise and global programs
  • HRBPs are embedded closely with business units and have regional or business reporting lines

 

Benefits of Hybrid

  • Combines efficiency of centralized processes with business alignment of embedded HRBPs
  • Flexibility to adapt services to business and regional nuances
  • Enables scalable global standards while supporting local innovation

 

Challenges and Mitigation

  • Requires strong governance to prevent confusion over responsibilities
  • Demands clear service level agreements (SLAs) and communication protocols
  • Needs continuous collaboration mechanisms across components

 

Real-World Example

A leading financial institution implemented a hybrid model, centralizing payroll and core CoEs, while embedding HRBPs in business units globally. This approach drove both operational excellence and strong business partnership.

 

2. Designing Roles, Responsibilities, and Handoffs

The strength of the HR operating model lies in the clarity of its roles and the quality of collaboration among Shared Services, CoEs, and HRBPs.

 

2.1 HR Business Partners (HRBPs)

HRBPs are strategic consultants embedded with business leaders, focusing on talent, organizational performance, and workforce solutions.

 

Key Responsibilities

  • Strategic alignment: Translate business goals into people strategies
  • Talent advisory: Workforce planning, succession, engagement, and culture
  • Change leadership: Partner in organizational change and transformation
  • Liaison: Facilitate access to CoEs and Shared Services expertise

 

Essential Skills and Attributes

  • Deep business acumen and commercial awareness
  • Strong consulting and influencing skills
  • Expertise in organizational dynamics and change management
  • Ability to interpret and leverage data and analytics

 

2.2 Centers of Excellence (CoEs)

CoEs provide deep, specialized knowledge in critical HR domains and develop frameworks, programs, and best practices.

 

Core Responsibilities

  • Develop global HR policies, tools, and frameworks
  • Deliver specialist consulting to HRBPs and leaders
  • Lead talent initiatives in domains like Learning & Development, Compensation & Benefits, Diversity & Inclusion, Talent Acquisition
  • Ensure regulatory compliance and market competitiveness
  • Generate insights and analytics to support strategic decisions

 

2.3 Shared Services

Shared Services deliver efficient, high-quality transactional HR services at scale.

 

Primary Duties

  • Process payroll, benefits, HR administration and employee data
  • Manage case resolution and employee queries
  • Provide consistent and timely service per SLAs
  • Support HR systems and technology

 

2.4 Managing Handoffs and Collaboration

Handoffs between Shared Services, CoEs, and HRBPs must be seamless to ensure positive employee and leader experiences.

Best Practices

  • Define clear role boundaries and decision rights
  • Develop process maps and workflows for common scenarios
  • Establish communication forums (e.g., joint meetings, shared platforms)
  • Align metrics and accountability for collaboration
  • Utilize technology for tracking service requests and status

 

 

3. Ensuring Strategic Alignment and Service-Level Clarity

 

3.1 Aligning HR Delivery with Business Strategy

To stay relevant and impactful, HR delivery models must evolve with business strategies.

  • Conduct regular operating model reviews linked to business priorities
  • Engage business leaders in HR governance forums
  • Use capability mapping and workforce analytics to prioritize HR focus
  • Customize HR offerings to business unit and regional strategies

 

3.2 Defining Service Levels and Managing Expectations

Establishing SLAs and clear expectations builds trust and drives continuous improvement.

  • Develop detailed SLAs for each HR service with measurable KPIs
  • Implement feedback channels for continuous service refinement
  • Use performance dashboards for transparency
  • Invest in customer service training for HR teams

 

3.3 Governance and Continuous Improvement

Sustainable operating models require ongoing governance:

  • Cross-functional HR councils and steering committees
  • Regular performance reviews and maturity assessments
  • Innovation programs for piloting new service delivery methods
  • Strong change management for new ways of working

 

4. Practical Insights and Common Pitfalls

 

4.1 Invest in Talent

  • Build HR teams with specialized CoE expertise and strategic HRBP skills
  • Provide ongoing learning and development tailored to new operating model demands

 

4.2 Balance Standardization and Localization

  • Use frameworks that allow local adaptation within global guardrails
  • Avoid rigid one-size-fits-all approaches that hinder agility

 

4.3 Leverage Technology Effectively

  • Invest in integrated HRIS platforms to connect Shared Services, CoEs, and HRBPs
  • Explore automation and AI for transactional efficiency
  • Use analytics for predictive insights and decision support

 

4.4 Manage Change Thoughtfully

  • Accelerated talent acquisition cycles
  • Stronger alignment of talent programs with innovation priorities

 

Conclusion

Designing effective Shared Services, Centers of Excellence, and HR Business Partners requires a strategic, holistic approach that balances operational efficiency with business intimacy. Clear role definition, seamless collaboration, robust governance, and continuous adaptation to business needs are paramount.

This operating model, when thoughtfully designed and implemented, positions HR as a true business enabler—driving talent strategy, organizational effectiveness, and measurable business outcomes.
