Protected: The True Cost of Complexity

Complexity creeps into supply chains quietly.A new SKU here. A customer-specific pallet height there. A regional exception that “just made sense at the time.” None of these decisions feel dramatic on their own. In fact, many are made with good intentions: to win business, to improve service, to meet local needs.But over time, complexity compounds. And when it does, it becomes one of the biggest – and least visible – drivers of cost, inefficiency, and emissions.
At James Ross Consulting, we regularly see organizations spending millions managing complexity they no longer need; simply because it has become normal.

Complexity Isn’t Free – It’s Just Poorly Accounted For

Most businesses can tell you how many SKUs they sell. Far fewer can tell you what each additional SKU actually costs to support.

Complexity doesn’t usually show up as a single line item. Instead, it spreads itself thinly across the organization:

  • Lower truck and container utilization

  • More warehouse handling steps

  • Higher inventory levels

  • Slower planning cycles

  • Increased damage, waste, and rework

  • More time spent firefighting exceptions

Each impact looks small. Together, they are anything but.

One global FMCG client we worked with had multiple factories producing the same products — but in slightly different formats, with different pallet heights, pack dimensions, and handling constraints. None of those differences were “wrong.” But collectively, they made the network far harder — and far more expensive — to run.

Where Complexity Really Comes From

1. SKU Proliferation

Product ranges grow faster than supply chains evolve.

New flavors, sizes, promotional packs, channel-specific formats – all driven by commercial logic. But every additional SKU introduces new planning variables, changeovers, forecasts, inventory positions, and packaging combinations.

The problem isn’t growth. It’s unmanaged growth.

Many businesses carry long tails of low-volume SKUs that absorb disproportionate effort across manufacturing, packaging, and logistics. These SKUs rarely get challenged because they “only” make up a small percentage of volume – even though they drive a large share of operational complexity.


2. Packaging and Format Variation

Small differences in packaging often create outsized consequences.

A few millimeters difference in case height can prevent double-stacking. A slightly different pack footprint can break pallet uniformity. A customer-specific configuration might force manual handling in an otherwise automated warehouse.

Individually, these seem like reasonable compromises. System-wide, they reduce flexibility and efficiency everywhere else.

In one case, a client had dozens of pallet heights in use across the same product family; each one originally agreed to satisfy a specific customer requirement. The result was underutilized trucks, inconsistent handling, and limited ability to rebalance volumes across sites.

3. Local Optimization vs Network Efficiency

Complexity often grows because decisions are made locally, not systemically.

A site optimizes for its own constraints. A sales team agrees to a bespoke format to secure a contract. A warehouse adapts processes to cope with exceptions. All of these decisions make sense in isolation.

But supply chains don’t operate in isolation.

Over time, local optimization fragments the network. What works for one factory or customer increases cost and rigidity elsewhere, and no one owns the full picture.


The Hidden Cost of “Managing Around” Complexity

One of the biggest red flags we see is when organizations become very good at managing complexity, instead of removing it.

Teams build workarounds. Spreadsheets proliferate. Extra checks get added. Manual processes fill the gaps between systems. The supply chain continues to function, which creates the illusion that everything is under control.

But this comes at a price:

  • Higher overheads

  • Slower decision-making

  • Increased risk of error

  • Reduced ability to respond to change

Complex systems are fragile. When demand shifts, costs rise, or disruption hits, complexity limits how quickly a business can adapt.


Complexity Is a Sustainability Problem Too

Complexity doesn’t just cost money. It drives emissions.

  • Poor pallet utilization means more trucks on the road

  • More changeovers and smaller runs increase energy use

  • Excess inventory increases waste and obsolescence

  • Bespoke formats often block automation and optimization

In one engagement, rationalizing packaging formats and pallet strategies removed thousands of unnecessary truck movements per year — delivering both financial savings and measurable carbon reductions.

Sustainability initiatives often focus on materials. But complexity reduction is one of the fastest ways to cut emissions without compromising service.


Why Complexity Persists

If complexity is so costly, why does it survive?

Because it hides well.

  • Costs are spread across departments

  • Decisions are locked in historically

  • No one wants to challenge customer agreements

  • The “risk” of change feels greater than the visible benefit

As McKinsey & Company has noted in multiple supply chain studies, complexity often grows incrementally until it reaches a tipping point — at which stage it becomes a strategic constraint rather than an operational nuisance.

Making Complexity Visible

The turning point usually comes when complexity is made visible in data.

When organizations model:

  • Cost-to-serve by SKU

  • Impact of packaging dimensions on pallet and truck utilization

  • Network-wide effects of local decisions

  • “What if” scenarios with fewer formats or standardized designs

Suddenly, long-standing assumptions get challenged.

In one FMCG case, modeling showed that under existing network constraints, millions in annual savings were achievable simply by reducing format variation — before any major structural changes were made.

Complexity wasn’t adding value. It was silently eroding it.


Reducing Complexity Without Damaging Service

Reducing complexity doesn’t mean stripping out choice or ignoring customers. It means being deliberate.

Effective approaches include:

  • SKU rationalization based on cost-to-serve, not just volume

  • Standardized packaging and pallet rules embedded into R&D

  • Clear guardrails for customer-specific requests

  • Network-level modeling before local decisions are approved

  • Designing flexibility into formats, rather than multiplying formats

The goal isn’t simplicity for its own sake. It’s useful simplicity – where variation exists because it creates value, not because it’s always existed.


The Strategic Payoff

Organizations that actively manage complexity see benefits beyond cost reduction:

  • Faster planning cycles

  • Better resilience to disruption

  • More scalable growth

  • Lower emissions

  • Stronger alignment between commercial and operational teams

Most importantly, they regain control of their supply chain instead of being controlled by it.


Final Thought

Complexity is rarely a single bad decision. It’s the accumulation of many reasonable ones, made without a system-wide view.

The true cost of complexity isn’t just what you spend today – it’s the opportunities you lose tomorrow because your supply chain has become too rigid to adapt.

The first step is making complexity visible. The second is deciding which parts still earn their place.

Here at James Ross Consulting our first step in de-complexing / simplification is to assess the end-to-end data. What is being produced, how, where and why. Using data to drive our analysis means we are able to look across categories and functions, to build a true picture of cost. Rationalisation may then cover the SKUs themselves, or it may keep the SKU’s but simplify how they are packed, so we share volumes, maximize efficiency, reduce inventory, improve efficiency and drive-up profitability.
