Root Cause Analysis: Practical Tips for Audit Firms
When your audit team receives feedback after a cold file review, whether it’s from your regulator, or an external provider like us, it can sometimes feel like a lot to digest. The key here is not just to react to the findings but to truly understand why things happened the way they did. This is where root cause analysis (RCA) comes in—a vital tool to not only resolve issues but also enhance your firm's audit quality going forward.
Here are some practical, hands-on tips to guide you through the RCA process and turn feedback into actionable improvements, all in a friendly, no-nonsense way.
1. Start with the Findings: Get Clear on What’s Being Flagged
First things first—review the findings carefully. Whether it's a comment from the regulator, us or an internal review, you need to get clear on what exactly is being flagged. It’s easy to get caught up in the details of what feels like a criticism, but take a step back and understand the core issues. Are you missing key documentation? Is there a gap in your testing? Are the conclusions not fully supported by the evidence?
Pro Tip: If not provided with your findings report, create a clear action list or summary that breaks down the main findings into specific areas that need improvement. This helps you see patterns and areas that might require deeper attention.
2. Ask "Why?" (And Keep Asking!)
The purpose of RCA is to uncover the underlying reasons behind the issues identified. And to do that, you’ve got to dig a little deeper. It's easy to focus on the surface-level symptoms (e.g., “The working papers weren’t properly completed”), but those are usually signs of a bigger issue.
Ask yourself:
Why was this issue flagged in the first place?
Why did the team miss this step or detail?
Were there any system or process failures that contributed?
Did we lack sufficient training or understanding of specific standards?
Could this be a communication issue, or was it simply a time pressure situation?
RCA is about peeling back those layers to get to the true root causes, not just addressing the immediate problem.
3. Engage the Team—It’s a Group Effort
You’re not in this alone. Get your audit team members involved in the RCA process. Ask for their thoughts on why things might have gone awry and what they think could have been done differently. Sometimes, the simplest answers come from those who are closest to the actual work.
Pro Tip: Encourage honest feedback and create an open environment where your team feels comfortable discussing any challenges they encountered during the audit. This helps uncover process bottlenecks or issues that might not have been obvious at first.
4. Look Beyond the File—Examine the Bigger Picture
Often, the issues flagged in a cold file review aren’t isolated. You might find that poor documentation or missed audit procedures are symptoms of broader systemic issues. Is there a pattern across multiple audits? Are there recurring themes around compliance with specific auditing standards?
Consider these questions:
Are there weaknesses in the overall audit process that could be impacting consistency?
Do we need better templates or checklists to guide the team through the review process?
Is there a gap in the training or resources available to staff on UK auditing standards?
Is the team under too much pressure to meet deadlines, leading to shortcuts or rushed work?
Root cause analysis should always consider the bigger picture—identify if there are recurring problems that need fixing at the process, training, or leadership level.
5. Create Actionable Solutions
Once you’ve identified the root causes, the next step is putting in place practical, sustainable solutions. These aren’t just quick fixes, but long-term improvements that can raise the quality of your audits and reduce future issues.
If you’ve found, for example:
Poor documentation: Maybe you need clearer guidelines or checklists to ensure all audit steps are documented thoroughly.
Missed audit procedures: Is it time for a training refresh on UK auditing standards or introducing regular peer reviews to catch gaps before the file gets reviewed?
Time pressure: Perhaps you need to revisit the planning phase of audits to ensure that there’s enough time to meet all requirements without cutting corners.
Pro Tip: Prioritise the issues that will have the greatest impact on quality and compliance. It might be tempting to tackle everything at once, but focusing on a few key areas first can lead to more meaningful improvements.
6. Monitor, Adjust, and Close the Loop
Root cause analysis is not a one-time task. After you’ve implemented solutions, you need to monitor the effectiveness of those changes. Set milestones to check on progress and keep your team engaged in continuous improvement. This is all part of ISQM 1.
Are the solutions you’ve put in place addressing the issues effectively?
Have you seen a reduction in similar findings in subsequent reviews or audits?
Is your team able to perform with more confidence?
Remember to regularly revisit and adjust your processes as needed, ensuring that you’re not just "fixing" a past issue, but building a stronger, more resilient audit team for the future.
By taking the time to perform a thorough root cause analysis after a cold file review or regulatory visit, you’re not only fixing immediate issues—you’re strengthening the foundation of your audits. The goal is always to learn from the feedback, improve your processes, and build a culture of continuous improvement within your audit team.
