The hidden cost of complexity is eroding your performance
Growth often brings hidden complexity that quietly erodes margins, slows decision-making and increases costs without ever appearing as a line on the P&L. This article explores the difference between necessary and unnecessary complexity, why it matters, and how leaders can identify the hidden tax affecting organisational performance before it becomes a strategic problem.

Complexity is the largest cost most businesses carry and the one no one can find on the P&L, there’s no line for it and no one sends you the bill.
It spreads invisibly – a little more cost to serve here, a slightly slower decision there, an extra system, an extra handoff, an extra layer – until one day you’re demonstrably slower and more expensive than smaller rivals and no one can quite say why.
We want to show you what that looks like when you actually add it up, because the shape of it surprises even the people running the business.
What complexity does when you’re not watching
It doesn’t arrive as a bill. It arrives as an EBITDA line that keeps drifting the wrong way while everyone points at the revenue going up.
The complexity challenge
Take a retailer we recently worked with, which over five years had expanded into new channels, marketplaces and markets, launched sub-brands and broadened its product range.
We built a complexity index for the business, which showed that over that period the organisation was roughly 40% more complex, and it had risen every single year. Each decision made sense in isolation, but together they left the organisation more complex – with the sharpest growth coming from channels, domains, marketplaces and currencies.
Over the same period, revenue grew by around 15%, but operating and technology costs rose faster, and EBITDA declined.
However, headcount increased by just 5% – the business had not become much bigger; it had become much more complicated, and that complexity was quietly eroding margin even as the top line continued to grow.
Not all complexity is bad – and that’s the trap
The easy conclusion is “cut complexity.” But it’s also the dangerous one, and it’s where most simplification programmes destroy value instead of creating it.
Some complexity is because of deliberate strategic choices – the channels needed to reach customers, the range that defines the proposition and the market presence that supports growth.
The real target is complexity that adds cost without value, such as duplicated systems, redundant products and outdated processes. The challenge is telling the difference, because blunt cost programmes often remove what drives growth while leaving the hidden waste untouched.
Speed is the cost you never counted
There’s a second cost inside complexity that the numbers above don’t even capture, and in a fast market it’s the most expensive of all.
Every layer you add is a decision you slow down. Complexity doesn’t only show up as cost; it shows up as the speed you’ve quietly lost – the extra sign-off, the additional stakeholder, the meeting before the meeting.
In a market where advantage is temporary and the ability to move quickly is a genuine weapon, being slow is a cost that never appears anywhere in the accounts and can matter more than all the ones that do.
Telling the two apart
This is the whole point of measuring complexity properly rather than just complaining about it.
The Organisational Performance Diagnostic indexes complexity across the dimensions that actually drive it – channels, customers, products, entities, systems, layers – and, because every lens reconciles to your group accounts, it connects that complexity back to what it’s costing you in real margin and real speed.
That’s what lets us separate the complexity that’s earning its keep from the complexity that’s just taxing you, so that when you simplify, you cut the second and protect the first.
Where to start
You can get a rough read this week. Pick three dimensions of your business – channels, product range, and management layers are good ones – and compare where they stand now against five years ago. Then put that next to your EBITDA over the same period. If complexity has climbed while margin has drifted down, and headcount hasn’t moved much to explain it, you’re paying the tax. The only question left is which kind, and that’s the one worth answering carefully before anyone starts cutting.
