Agentic AI in HR: Scale service delivery without losing control

Gartner’s latest Flex report positions agentic AI as a turning point for HR, not just an efficiency gain. As AI agents take on most Tier 0 and Tier 1 activities, they warn that HR’s operating model and value proposition are at risk. 

For CHROs, the challenge goes beyond adoption. It’s about ensuring agentic AI reshapes HR on HR’s terms, not those of IT or other stakeholders in the business.

What are tier 0 and tier 1 activities? 

Tier 0 and Tier 1 activities cover HR’s most routine, ongoing responsibilities, including administration, payroll, L&D, recruitment, and employee support. The distinction between them is defined by complexity and escalation: 

• Tier 0: Employee self-service tasks such as booking time off or submitting basic workplace queries. Automating Tier 0 work with agentic AI reduces the number of issues that escalate further. 

• Tier 1: Requests handled by shared services or helpdesks when selfservice isn’t sufficient, traditionally requiring human support. 

Agentic AI can manage most Tier 0 activity with minimal visible change, while more complex Tier 1 requests are handled by specialized agents. Human intervention is only when resolution isn’t possible. 

The business impact of agentic AI automation 

82% of HR leaders plan to deploy agentic AI in the next 12 months. Gartner predicts that the use of AI in HR will have profound impact on its operations within businesses. In many ways, it’ll be outright beneficial. In others, however, it will create issues that human-led HR teams must contend with. 

Simplified employee experience 

One of the biggest benefits of using agentic AI for HR automation is the removal of friction for employees. The fewer obstacles and disruptions employees experience when engaging with HR processes, the less likely they are to give up on them. 

That means more employee buy-in during a time of significant change. It also means less likelihood of performance and engagement issues being swept under the rug. 

For example, if employees won’t engage with an awkward system for booking time off, you risk increasing burnout and absenteeism. With AI agents, employees can view availability and lock in their vacation days with minimal effort. 

Ownership and strategic focus 

As agentic AI takes over routine HR interactions, the biggest shift is one of ownership. When AI agents become the default interface for Tier 0 and Tier 1 work, control over processes, data, and decisions starts to move away from HR unless it’s deliberately reclaimed. 

That makes strategic focus critical. HR leaders must decide which responsibilities remain human-led. That means figuring out where decision rights sit and how HR continues to shape outcomes rather than simply respond to them. Agentic AI can remove administrative load. But only clear ownership ensures HR retains authority over the sensitive, high impact work that defines its value. 

Reduced and consolidated HR responsibilities 

According to Gartner, “In the short term, AI agents will reduce the need for local human HR support and decrease demand for country – or region-specific service hubs. As a result, HR shared services will become more centralized and standardized, which is a necessary step to fully utilize AI technologies.” 

With AI set to automate 50% of HR tasks and automate the rest, HR may no longer need to scale headcount to keep pace. This shift signals a broader change. Removing entry-level work risks weakening succession pipelines, while some organizations may decentralize HR responsibilities entirely. That makes it critical for HR leaders to clearly demonstrate the value of human-led HR.

How HR must adapt to agentic AI 

Since agentic AI is here to stay, HR leaders must decide how best to work with it. Will you lean into decentralization and automation for maximum productivity gains, or does the human touch make an important difference? Should different areas of the business handle their own HR upkeep, or is there expertise only your team can provide? 

Should you outsource or merge shared services? 

Gartner’s report details a critical choice for HRDs: do you outsource shared services or merge them with other internal functions to form combined Global Business Solutions (GBS)? 

Outsourcing shared services could potentially lower the cost of AI implementation, freeing up resources for experimentation and risk-taking. On the other hand, it may limit your access to data on things like employee sentiment. This could make it hard to authentically support the employee experience. 

Merging shared services keeps data in-house, making it easier to leverage for hyper-personalization. But it could also increase deployment costs, and you’d ultimately be responsible for any issues. 

Transform HR operations into digital services and delivery 

As shared services move out of traditional HR operations, Gartner frames this not as a loss of influence but as a structural reset. The opportunity is to elevate HR operations from transaction management to digital service delivery, with clearer ownership of design, governance, and outcomes. 

The model relies on flexible delivery pods anchored in a central PMO. This enables Centers of Excellence to work closely with the business to implement and scale HR products using agile methods. 

Agentic AI augments people relations management by monitoring compliance and surfacing risks, while accountability for sensitive, judgment-based decisions remains firmly human-led. At the same time, AI extends the reach of HR business partners, allowing them to support larger populations or regions while focusing on strategic decision-making, escalation, and stakeholder alignment.

HRDs must lead agentic AI adoption 

Agentic AI will reshape HR whether HR leads the change or not. Gartner is clear that automating Tier 0 and Tier 1 work is only the starting point. The real impact lies in how HR redefines its operating model, roles, and ownership as AI agents become embedded across the organization. 

For CHROs, this is the moment to act deliberately. By leading agentic AI adoption, HR can protect its strategic role, retain decision rights, and ensure that the most complex, human-led work remains where it belongs. Without that leadership, those decisions won’t disappear. They’ll simply be made elsewhere.
