Your HR operating model made sense before, so why isn’t it holding up now?

By Laura Muldoon

What used to work in HR isn't working the same way anymore

The structure is familiar. The roles are defined. The processes are in place. On paper, your HR operating model looks right because it was right, for a different version of your organization.

But day to day, something's off. Decisions take longer than they should. Managers are asking more questions. Employees expect faster, clearer answers. New tools get introduced, and instead of reducing the noise, they add to it.

What looks like a performance problem is in fact a design problem.

When "working" isn't the same as "working well"

Most HR operating models weren't built all at once. They evolved, shaped by what the organization needed at a specific point in time: rapid growth, global expansion, or a stabilization period. That's exactly why they start to strain.

The model was designed for different conditions. More time to plan. More room in the budget. A more predictable pace. It made sense because it matched how the business operated then.

Today, the conditions are different. Budgets are tighter, expectations are higher, and HR teams are being asked to move faster and support more complex decisions. The model still reflects the past while the demands are firmly in the present.

Where things start to break down

The strain rarely shows up all at once. You can usually start seeing it in small moments: a manager unsure where to go for support, an HR team spending more time answering basic questions than doing strategic work, or a process that technically exists but doesn't quite fit how work actually happens anymore.

A few patterns come up consistently:

• Decision-making slows down. What used to be straightforward now requires more input, more alignment, more time. The structure wasn't designed for the current level of complexity, so decisions either get escalated or delayed.

• Capacity gets stretched. HR teams end up caught between maintaining existing processes and responding to new demands. Without something being simplified or removed, the workload just accumulates.

• Ownership gets murky. As organizations evolve, responsibilities shift. What once sat neatly within one team becomes shared across several and without clear boundaries, work either gets duplicated or falls through the cracks.

• The employee experience suffers. Managers and employees expect quick, consistent answers. When they don't get them, it's rarely because people aren't trying but because the system behind the scenes isn't set up to deliver.

The added pressure of AI

AI is often positioned as the fix for all of this. It can be powerful but it also exposes what's not working.

Unclear processes? AI will surface that. Inconsistent policies? AI reflects the confusion back, faster. Decision-making that relies on informal knowledge rather than documented guidance? Technology can't replace that.

Where the fundamentals are strong, AI genuinely helps: it speeds up access to information and reduces burden on HR teams. Where those fundamentals are less defined, it tends to make the gaps more visible, not smaller.

This is why introducing new technology without revisiting the operating model often backfires. The expectation is simplicity. The reality, without addressing the underlying structure, is more complexity.

Fixing it isn't about starting over

When a model starts to feel stretched, the instinct is to redesign everything: new structures, new roles, new processes. That's rarely what's needed.

Most organizations don't have a fundamentally broken operating model. They have one that hasn't been adjusted to reflect how the business works now. The goal isn't to replace it but to realign it.

That starts with understanding where the pressure is coming from:

• Where are decisions slowing down?

• Where are teams spending most of their time?

• Where are employees getting stuck?

• Where is work being duplicated or not picked up at all?

These questions usually reveal that the biggest challenges aren't structural at a high level. They sit in the details: how work flows, how responsibilities are defined, how clearly things are communicated.

Where to focus

A few areas tend to make the biggest difference:

• Clear ownership. When decision-making boundaries are understood, a lot of unnecessary back-and-forth disappears. People spend less time figuring out who should do what and more time actually doing it.

• Simplification. Processes accumulate layers over time. Stripping them back to what's essential makes them easier to follow, easier to maintain, and frees up capacity for higher-value work.

• Consistency. When similar situations are handled differently across the organization, it creates confusion and slows everything down. More consistency in how decisions and processes are applied means a more predictable experience for everyone.

• Integration. New technology, new ways of working, new capabilities — these need to fit into how work already happens. When they sit alongside existing processes rather than within them, they add effort instead of reducing it.

A model that can keep up

A strong operating model isn't one that never changes. It's one that can adapt without breaking under pressure.

For HR leaders, this often starts with a simple question: if we were designing this today, knowing what we know now, what would we keep and what would we do differently?

The answer is rarely everything or nothing. More often, it's targeted adjustments that remove friction, clarify ownership, and make it easier for teams to do their best work.

An operating model isn't just about structure. It’s the way HR is set up that helps the business move forward (or holds it back). Right now, for many organizations, that's the question worth sitting with.
