The most resilient organisations are built on both functions firing at full strength – in the same direction.

Supply chain and procurement have more in common than most organisational charts suggest. Both functions exist to ensure the business has what it needs – at the right cost, from the right sources, with the right level of risk. Both are operating in an environment that is more volatile, more regulated, and more strategically consequential than it was a decade ago.

And yet, in many organisations, they continue to operate in parallel rather than in partnership – shaped by separate KPIs, separate conversations with the C-suite, and separate views of the same supply base.
The organisations navigating today’s complexity most effectively tend to be the ones that have worked out how to change that.

What Each Function Brings

Supply chain’s value lies in execution and flow. Getting product to market, managing inventory, maintaining service levels, coordinating logistics across complex networks – this is highly skilled work that requires deep operational knowledge and the ability to manage multiple interdependencies simultaneously. In volatile conditions, a strong supply chain function is what keeps the business running.

Procurement has travelled a long way from its origins as a back-office function raising purchase orders and chasing deliveries. Today, a mature procurement function brings deep category expertise – a working understanding of supply markets, cost structures, supplier economics, and the commercial levers available at each stage of a category lifecycle. It brings rigour to negotiation and contracting, not simply in securing the best price, but in building agreements that protect the organisation against dependency, lock-in, and one-sided risk. It brings scenario planning capability – the ability to model what happens to costs and supply security under different market conditions before those conditions arrive, stress-testing assumptions with tools and frameworks that translate commercial uncertainty into decisions the business can act on.

There is also a less celebrated but equally important role: procurement as the function that maintains the commercial discipline in a supplier relationship that supply chain, rightly focused on continuity and partnership, sometimes cannot. This is not adversarial – it is a necessary counterbalance that ensures the relationship remains genuinely mutual, and that operational dependency never quietly becomes commercial vulnerability.

Together, these two functions cover both sides of the equation: what the business needs to deliver, and what the market is able to provide. Separately, each holds a partial view.

The Moments That Reveal the Value of Partnership

Three situations, in particular, show what is possible when procurement and supply chain are working in genuine alignment.

The first is new product or service development. When procurement is involved at the design stage – before specifications are locked and supplier assumptions are baked in – it can shape commercial outcomes in ways that simply are not available later. Knowing which suppliers have capacity constraints, which materials carry lead time risk, and where cost pressure is likely to build before a product even launches is genuinely valuable intelligence. Supply chain brings the production and fulfilment reality. The combination consistently produces better decisions than either function arrives at alone.

The second is disruption response. The Houthi attacks on Red Sea shipping and the more recent crisis in the Strait of Hormuz – through which approximately 20% of the world’s seaborne oil trade normally passes – have demonstrated with exceptional clarity what happens when critical trade routes are compromised simultaneously. The organisations that have responded most effectively are those where procurement and supply chain shared a live view of the risk landscape before the disruption hit, and had the working relationships to move fast together. Two functions receiving the same bad news at different times, working from different datasets, rarely produce a coherent response.

The third is sustainability. This is where the partnership between the two functions is perhaps most underdeveloped – and where the stakes are rising fastest. Supply chain holds operational data on emissions, logistics intensity, and manufacturing standards. Procurement holds the supplier relationships and the contractual levers to drive change. Research from the CASME global procurement community confirms that procurement’s involvement in sustainable sourcing is critical precisely because the organisation’s principles need to be embedded into business processes and supplier decisions — not left as a reporting exercise. That embedding only happens when procurement and supply chain are working from a shared agenda.

What Good Looks Like in Practice

A small number of organisations have built this kind of partnership into how they operate — and the results are instructive.

Tata Steel manages approximately $10 billion in annual procurement spend under a function recently elevated as Group Strategic Procurement and Business Excellence — a deliberate repositioning of procurement as an enterprise value driver, connected to and working alongside supply chain’s execution capability. Each function makes the other more effective.

PETRONAS, Malaysia’s national energy company, has built its Supplier Support Programme on the recognition that sustainable supply chains require procurement’s supplier relationships working in concert with broader operational commitments. The programme works directly with over a thousand suppliers – the majority local SMEs – to build ESG capability, improve sustainability reporting, and access transition financing. This is procurement and supply chain operating as a joined-up ecosystem.

Apple, consistently benchmarked as one of the world’s most effective supply chains, built its operational excellence on a foundation of procurement discipline. Both of the executives who shaped that supply chain over the past two decades came up through procurement before taking on broader operational leadership – a reflection of the view that supplier intelligence, commercial rigour, and market knowledge are foundations, not add-ons

The Question Worth Asking Together

If pressed, most supply chain leaders would acknowledge they do not have a complete picture of what a well-functioning procurement team is capable of delivering. Most procurement leaders would say the same in reverse. That gap is what happens when two functions have been designed to solve different problems, measured against different targets, and left to get on with it.

The current environment has made that arrangement harder to sustain. The Houthi attacks on Red Sea shipping and the ongoing crisis in the Strait of Hormuz are only the most visible examples of a broader pattern: events with a geopolitical origin land on procurement and supply chain simultaneously, and the response is only coherent when both functions are working from a shared picture before the disruption arrives, not after.

Which raises a practical challenge, aimed equally at supply chain and procurement leaders: identify one category, one supplier relationship, or one risk scenario where your two functions are currently operating separately – and work it together instead. Not as a pilot programme or a task force. One thing, done jointly, with shared accountability for the outcome. The organisations that have built genuine partnership between these two functions tend to find that both perform better for it. The ones that have not are leaving value on the table that someone else will eventually pick up.
