For almost three decades, the HR Business Partner model (originally coined as part of Dave Ulrich’s three-legged stool, 1997) has been the dominant paradigm for aligning people strategy with business priorities. It represented a meaningful evolution from administrative HR, placing people professionals closer to decision-making and increasing their relevance at the leadership table. For a long time, it worked well—and in many organisations, it still does.

But it was designed for a different era.

The context in which organisations now operate has shifted fundamentally. In an environment shaped by AI, automation, digitisation, and increasingly robotics, the Business Partner model is starting to show its limits. Not because it was flawed, but because it was never designed for a world where the nature of work itself is being redefined in real time.

Having been involved in many HR redesigns, a new role seems to be emerging, one that moves beyond alignment and into active design: let’s call it Workforce Strategist for now (or in the USA the emerging tread is People Strategy Partners but is that a clear enough distinction from today?).

The traditional Business Partner model was built for a world where work was relatively stable, workforce planning was incremental, and organisational models evolved slowly (despite at times best efforts around transformation). Today, these assumptions are being challenged. The question is no longer just how to organise people effectively, but whether the work itself should exist in its current form.

In this context, HR is increasingly being asked to answer questions that go well beyond partnership. What work should exist in three to five years? Which activities should be automated, augmented, or eliminated? What capabilities will genuinely differentiate the organisation in an AI-enabled market? 

These are not support questions. They are design questions, arguably some of the most important design questions in the organisation.

To operate effectively at this level, HR professionals need to develop a different set of muscles.

First, there is a need for much stronger data and analytical fluency. Workforce decisions can no longer rely on experience, instinct, or a well-crafted narrative. They must be grounded in a clear understanding of where value is created, how work flows, and what drives productivity. This does not mean HR needs to become a technical analytics function, but it does mean being able to engage confidently with data and, just as importantly, to challenge it when needed.

Alongside this, scenario modelling becomes essential. Static workforce plans are increasingly redundant before they are even finalised. Instead, HR needs to model different futures, exploring, for example, what happens if 30–40% of transactional work is automated, if AI reshapes decision-heavy roles, or if the organisation simplifies its product and service offering. The objective is not perfect forecasting (always a tough pursuit), but structured thinking that helps leaders make better decisions under uncertainty.

Equally important is a working literacy in AI and automation. HR does not need to build these technologies, but it does need to understand what they can do, where they create value, and where they are still more promise than reality. Without this, HR risks becoming politely sidelined in the most significant transformation conversations happening in the organisation. The critical shift here is to move from thinking about jobs as fixed entities to understanding work as a set of tasks, some of which will remain human, some of which will not.  HR needs to be seen as the partner to technology in driving this change.

As this evolution takes place, certain aspects of the traditional HR model will naturally diminish. Transaction-heavy activities, many of which still occupy a surprising amount of HR capacity, will continue to be automated or absorbed into digital platforms and shared services. This is not particularly controversial, it is already happening. More subtly, forms of business partnering that are largely reactive (e.g. interpreting policy, resolving day-to-day issues, and attending meetings without materially shifting outcomes) will also become less relevant. These activities may persist, but they are unlikely to define the future of the function.

In their place, higher-value activities must expand. Strategic workforce planning becomes central, with HR playing a meaningful role in shaping decisions about where to invest, where to reduce, and how to reconfigure capability. Work and job design, which has been in my experience historically underdeveloped in many organisations, emerges as one of the most powerful levers for productivity. This involves deconstructing roles, reallocating tasks, and redesigning jobs to maximise value creation in an AI-enabled environment. It is not glamorous work, but it is where a significant portion of value is either unlocked or lost.

At the same time, HR needs to take a more active role in operating model design. Questions about structure, governance, spans of control, and the balance between centralised and embedded capabilities sit squarely at the intersection of people, work, and performance. This is precisely where HR should be operating.

Ultimately, this shift is as much about mindset as it is about capability.

The Business Partner model is grounded in the question: “How do I support this leader?”

The Workforce Strategist asks: “How do I support this leader in how their work is designed and delivered to achieve the strategy?”

They start with, “What work should exist, and how should it be done to deliver our strategy?”

It is a subtle shift in wording, but a profound shift in impact.

Because once HR starts asking those questions it becomes more than a function that gets invited into conversations after design decisions have been made. It becomes a core architect of how the organisation actually performs.

And in a world where competitive advantage increasingly comes down to how effectively work is designed and executed, that is not a bad place to be.
