An auditor's guide to arguing with your auditor or how to tell your auditor they're full of it (professionally)

You're sitting in an audit closing meeting. Your auditor has just raised a finding you disagree with. Maybe the evidence was misunderstood. Maybe the finding is based on how they'd do it, not what the standard actually requires. Maybe they've wandered into areas that weren't in the audit plan. But you don't say anything. You nod, accept the finding, and spend the next three months implementing a corrective action you don't believe in.

Sound familiar? It happens every day. And it's a problem.

Not because auditors are always wrong (we're not, mostly), but because the power dynamic in a certification audit discourages healthy challenge. 

Most organisations treat their auditor like a teacher they need to impress rather than a professional they're entitled to question. Which results in weaker management systems, wasted effort on unnecessary corrective actions, and a certification process that serves the auditor's convenience rather than your improvement.

We run a certification body offering certification across six ISO schemes. We sit in the auditor's chair every week. And we're here to tell you: you have more rights in this process than you think, and a good auditor actually welcomes being challenged.

This session gives you the practical tools and confidence to push back when it matters. We'll cover five areas.

First, what auditors are actually required to demonstrate. Every nonconformity needs objective evidence against a specific clause. We'll show you what that looks like and how to spot when a finding is just an auditor's preference wearing a nonconformity's hat.

Second, the difference between "that's wrong" and "that's not how I'd do it." We'll share real examples of findings we've seen raised across the industry that should have been challenged but weren't.

Third, scope creep. Your audit plan defines the boundaries. When an auditor starts exploring outside them, you're entitled to redirect. We'll explain how to do it without blowing up the relationship.

Fourth, your rights under ISO 17021-1. This is the standard that governs certification bodies. It gives you specific entitlements around appeals, complaints, and auditor conduct that most organisations have never heard of.

Fifth, the red flags. The certification industry has had its share of integrity problems. We'll share the warning signs that suggest your certification body is prioritising revenue over rigour, and what your options are when you spot them.

This isn't about being adversarial. It's about creating honest audit relationships where both sides are working toward genuine improvement rather than performative compliance. You'll leave knowing exactly when to push back, how to do it well, and what to do when the process lets you down.

Because the best audits we've ever done are the ones where everyone is working in the room to get the best outcome and aren't afraid to have the hard conversations on either side.
