The Operational Leader’s Hidden Risk

In many organisations, customs processes are managed day to day within supply chain or logistics. For an Operations Director, it’s easy to assume these tasks are well in hand especially if the team has been doing them for years without incident.

But what if those processes aren’t as robust as they appear? What if the people managing them don’t have the specialist skills or experience to recognise where the real compliance gaps are? 

This isn’t about poor performance. It’s about a recognised cognitive bias. In 1999, David Dunning and Justin Kruger identified what became known as the Dunning-Kruger Effect, a tendency for those with low ability in a given area to overestimate their competence. 

“People tend to hold overly favourable views of their abilities in many social and intellectual domains.”

In customs, this can mean that operational teams feel confident their work is fully compliant, not because it is, but because they lack the technical insight to see the flaws. 

Behind the Culture of “Everything is Fine” Lies Hidden Risk

Overconfidence can create a culture where processes go unchallenged and external review is resisted. Sometimes this is about protecting ownership of the work, but often it’s simply because the team believes there is nothing to find. 

Phrases like “we’ve always done it this way” or “this is how our broker told us to do it” can conceal significant operational weaknesses, including: 

• Delays in shipments and goods stuck at port.
• Product misclassifications repeated over years.
• Valuation errors leading to over or underpayment of duty inadequate origin documentation.
• Poor record-keeping that wouldn’t stand up to HMRC scrutiny.

These aren’t just administrative issues. They can lead to costly delays, rework, or full-blown customs investigations. 

Why Operations Leaders Must Act Now

Customs requirements are evolving fast. Post-Brexit changes, new trade agreements, and HMRC’s increased use of data-led auditing mean the landscape is far less forgiving. 

For Operations Directors, the risks include: 

• Disruption: Non-compliance can lead to shipment holds, missed deadlines, and supply chain bottlenecks.
• Cost escalation: Fines, duty repayments, and lost reclaim opportunities directly hit operational budgets.
• Reputational damage: Suppliers and customers may lose confidence in your ability to move goods efficiently and compliantly.

The Critical Role of Independent Review

An external customs audit isn’t about undermining your team; it’s about providing an extra layer of assurance that the processes in place are fit for today’s trading environment. 

Independent reviews can: 

• Confirm that operational processes are aligned with current regulations.
• Identify process inefficiencies that increase cost or risk.
• Highlight opportunities for improvement or savings.

It’s a way to strengthen your operation, not criticise it. 

In customs, confidence without capability can create unseen vulnerabilities. For operations leaders, the key is not to assume that “no news is good news,” but to make sure your team’s confidence is backed by proven competence. 

The Dunning-Kruger Effect reminds us that without the right expertise, even the best-intentioned teams can miss critical risks. And in operations, the cost of those blind spots is felt across the entire supply chain.
