A CEO is preparing to launch a new product line. Speed is critical. The window is narrow.
To move, she needs an integrated plan — finance, workforce, supply chain, technology, all aligned. She calls a meeting. Within hours, she has representatives from six different departments in the room. Each one owns a piece of the puzzle. None of them owns the whole picture.
Three weeks later, the plan still isn't finished.
The departments weren't obstructing deliberately. They were working exactly as designed. The problem is that the design is 60 years old.
The Statistic That Should Concern Every Business Leader
In Deloitte's 2026 Global Human Capital Trends survey — conducted across more than 9,000 leaders in 89 countries — 66% of C-suite leaders agreed that it is very or extremely important for their organisations to push beyond the boundaries of traditional organisational functions. Only 7% are making great progress in doing so.
Read that again. Two thirds of senior leaders know their functional structure is a problem. One in fourteen is actually fixing it.
That gap — between the recognition of a problem and the willingness to act on it — is not unique to the boardroom. It shows up at every level of every organisation, from the FTSE 250 to the 30-person trades business that's growing faster than its processes can handle.
The structure differs by scale. The failure mode is identical.
What Functions Were Actually Built For
The departmental model — HR, Finance, IT, Legal, Operations, each in its own vertical — was not designed with your business in mind. It was designed for an era in which specialised knowledge was scarce, expensive to develop, and difficult to distribute.
If you needed legal expertise, you hired lawyers and put them in a Legal department. If you needed financial oversight, you hired accountants and gave them a Finance team. The walls between those groups were a feature, not a bug. They protected the integrity of specialised practice. They ensured accountability. They gave boards a clear line of sight to function-specific performance.
That logic made sense when information moved slowly, when processes were predominantly manual, and when the primary challenge was scaling human expertise across a growing organisation.
None of those conditions still hold.
Information moves in real time. Processes that once required specialist intervention can now be handled by automated systems in seconds. And the primary challenge facing most organisations isn't scaling expertise — it's integrating it fast enough to respond to a world that doesn't wait.
The Two Things Your Functions Are Actually Doing
Here is the framework that cuts through the complexity.
Inside every corporate function — regardless of how it's named or how large the organisation is — there are two fundamentally different types of work happening simultaneously.
1. "Run the Business" Work
This is the engine room. Payroll. Invoice processing. Compliance reporting. IT support tickets. HR onboarding paperwork. Supplier purchase orders.
These tasks are repeatable. They follow consistent rules. They require accuracy and reliability more than creativity or judgment. And — critically — they are already more automatable than most organisations have acknowledged.
Deloitte's research identifies a clear pattern here: routine workforce inquiries and transactions have been transformed by self-service technology and AI that can address the need for tier 1 support — whether that need arises from HR, IT, Finance, or Procurement. Increasingly, the data to satisfy those requests and the workflow technology supporting them are already integrated.
The technology doesn't care which department a task came from. It cares whether the task follows a pattern it can replicate.
2. "Grow the Business" Work
This is where human expertise still creates irreplaceable value. Mergers and acquisitions. Strategic workforce planning. New market entry. Managing regulatory risk. Building and sustaining client relationships.
These activities require judgment, pattern recognition across incomplete information, and the ability to hold multiple competing priorities in tension — often simultaneously.
No automation does this well. And the humans who do it well are expensive, scarce, and currently being buried under "run the business" work that has nothing to do with their actual capability.
That is the core dysfunction. Your most valuable people are spending a material portion of their time on tasks a well-configured system could handle.
The Maths That Makes This Uncomfortable
Let's put numbers to it, because abstract arguments about organisational design are easy to defer. Specific costs are harder to ignore.
Take a mid-sized professional services firm. Three senior consultants, each earning £65,000 per year. Fully loaded — including employer National Insurance contributions, pension, holiday pay, and non-billable overhead — that's approximately £85,000 per person, or roughly £53 per productive hour.
Each consultant spends, conservatively, six hours per week on "run the business" tasks: contract preparation, invoice generation, CRM (customer relationship management software) updates, compliance documentation, internal reporting.
Six hours per week. Per person. Three consultants.
That's 936 hours annually. At £53 per hour: £49,608 per year in senior consultant time spent on work that doesn't require a senior consultant.
Now scale that logic to a 50-person organisation. Or a 500-person one. The number doesn't shrink proportionally — it compounds. Because as organisations grow, they don't just add headcount to "grow the business" functions. They add layers, approvals, handoffs, and co-ordination costs that sit almost entirely in the "run the business" category.
In the last three years, headcounts in areas such as HR, sales and support, and business management have shrunk considerably, and US public companies have cut white-collar workforces by 3.5%. That reduction isn't happening because those roles were unnecessary. It's happening because the work those roles performed is being absorbed by technology — often imperfectly, because the underlying process design was never rethought.
Cutting headcount without redesigning the process just means the remaining people are doing the same broken work, with fewer hands.
What Rethinking This Actually Looks Like
The organisations making genuine progress on this aren't drawing new org charts. They're asking a different question: not "how do we restructure our departments?" but "which of our processes belong to a system, and which require a human?"
At the enterprise level, the examples are instructive.
Moderna merged its HR and IT functions under a single leader — not because the two departments happen to sit near each other on a floor plan, but because many talent practices are now being reimagined with technology and AI, and with data being integrated from across multiple functions. The result was more than 3,000 customised AI tools deployed for specific HR tasks, with teams rebuilt around work that genuinely required human input.
Unilever restructured its CFO's remit to include supply chain, procurement, digital, and technology — recognising that the traditional boundaries between those functions were creating slower, more expensive decisions than the business could afford.
These aren't cost-cutting exercises dressed up as innovation. They are genuine structural responses to a shift in where human judgment adds value.
For the SMB leader reading this, the translation is more immediate and less complex.
You don't have six corporate functions. You may not even have six people in a given department. But you almost certainly have the same fragmentation — the same pattern of expert people (or your only people) spending significant time on work that follows a rule, repeats on a schedule, and produces a predictable output.
The SMB version of "Moderna merging HR and IT" is: stopping your operations manager from manually updating three different systems every time a new client is onboarded, and building one automated flow that does it in 90 seconds.
The principle is identical. The scale is different. The urgency is, if anything, higher — because in a 20-person business, one person buried in "run the business" work is a proportionally much larger cost than in a 2,000-person enterprise.
The Question Worth Sitting With
Deloitte's research surfaces a striking tension: while over half of executives say their corporate functions work together, more than half also say those functions are in need of substantial reinvention in both capability and mission.
They know it's broken. They know it needs fixing. And 93% of them aren't making meaningful progress.
The reason isn't ignorance. It's inertia. Functional structures are embedded in reporting lines, in budget ownership, in people's professional identities. Dismantling them — even partially, even intelligently — requires someone to be willing to ask an uncomfortable question out loud: is the way we've organised this actually serving the business, or is it serving the structure?
That question doesn't get easier the longer you wait. The gap between organisations that have started to separate "run the business" work from "grow the business" work — and those that haven't — is widening every quarter.
Summary
Functions weren't built to slow businesses down. They were built to organise expertise at a time when organising expertise was the hard problem.
That problem has been solved. The hard problem now is integration — getting the right information, decisions, and actions to happen at the right time, without friction, across whatever boundaries an org chart happens to have drawn.
The businesses winning the next decade aren't the ones that restructured their departments most boldly. They're the ones that honestly identified which of their processes belong to a system — and acted on that answer first.
That's true whether you're running a FTSE 250 with 40,000 employees, or a telecoms business with 35 people and a CRM that nobody enjoys using.
