The HR operating model that replaces fragmented outsourcing

The real cost of a fragmented HR department

For most HR departments, the issue is not a lack of effort or talent. It is the operating model. HR teams are expected to handle employment law compliance, talent acquisition, employee onboarding, payroll runs, and strategic initiatives — all at the same time, with the same headcount. This often results in HR teams neglecting strategy to focus on administration.

The administrative function of HR has expanded significantly as organisations grow. HR tasks that were manageable at 200 employees become a structural burden at 2,000. Growing companies face a compounding problem: as business growth accelerates, so does the volume of HR work, without a proportional increase in HR resource to absorb it. The result is an HR team permanently at capacity, unable to focus on the people strategies that drive performance.

Traditional HR outsourcing services are often used as point solutions, but don't address the larger structural issue. An organisation might outsource payroll to one provider, retain an HR consultants firm for specific tasks, and manage employee experience in-house — creating a fragmented model with multiple vendors, inconsistent data, and no single point of accountability when things go wrong.

The cost of this fragmentation is measurable. According to Gartner, HR technology solutions were not at all successful (26%) or only slightly successful (32%) in reducing the cost of HR operations. This is because technology applied to a broken operating model automates the fragmentation, not the solution. For management teams and HR leaders alike, cost savings remain elusive when the underlying model remains unchanged.

Human capital management requires a different approach. Not more tools. Not more HR consultants on retainer. A new operating model — one where HR administration, multi-country payroll, compliance management, and strategic HR support are integrated under one provider, one data model, and one point of accountability.

The problem with traditional HR outsourcing services

Most organisations trying to reduce HR overhead reach for the same tools: a new HRIS implementation, a self-service portal, or another layer of HR managed services bolted onto an already fragmented operating model. The result is the same every time — more vendors, more data silos, and an HR team still consumed by operations.

The whitepaper From cost centre to value driver sets out why these approaches fail, and what executives actually need from HR in an era when agentic AI, multi-country payroll complexity, and workforce transformation are happening simultaneously.

What our HRaaS whitepaper covers

The HR operating model reset is a practical guide for HR leaders and business owners navigating the gap between what the business demands of HR and what the current operating model can realistically deliver. It draws on Gartner and Deloitte research to make the structural argument for change, and explains how  an integrated HRaaS model closes that gap.

Why current models don't address HR workload

HR administration consumes 2.22 FTEs per 1,000 employees. Payroll outsourcing services managed separately from HR create fragmentation that no amount of automation resolves.

The HR as a Service operating model explained

HRaaS is not another outsourcing arrangement. It is a dual-layer model: business-as-usual operations that run reliably every day — covering HR administration services, multi-country payroll, and HR compliance management — alongside consulting services that deploy when your organisation needs HR transformation services, HRIS implementation support, or on-demand HR business partner expertise.

Four integrated HR service pillars

The model covers:

• HR Operations (end-to-end HR administration with integrated payroll)
• HR Partner Plus (on-demand HR business partner access without permanent headcount)
• HR Technology (HRIS optimisation and AI-enabled analytics on your existing platform) and
• HR Transformation (project-based advisory for specific challenges).

Together, they give you HR shared services without the fragmentation of a multi-vendor model.
