Root Cause Analysis Methodologies

Master the critical technique now mandated by Global Internal Audit Standards. The IIA GIAS requires internal auditors to implement systematic Root Cause Analysis (RCA) methodologies and report root causes plus best practices to senior leaders and the board. This foundational course moves beyond the limited '5 whys' approach to equip you with a sophisticated RCA toolkit that delivers genuine insight without slowing your assignments.

Discover how to distinguish immediate, contributing, and root causes while understanding the eight common failure modes across governance, risk, and control environments. Learn to leverage AI-powered causal analysis tools that can rapidly map cause-effect relationships, identify systemic patterns across multiple findings, and generate sophisticated fishbone diagrams and fault trees at scale. You'll see how effective RCA actually accelerates audit work through smarter scoping, focused testing, and more insightful thematic reporting to audit committees.

Who Should Attend?

Experienced auditors, audit managers, and heads of internal audit seeking to elevate analytical depth and satisfy new GIAS requirements.

What Will You Learn?

• Navigate new IIA requirements for root cause analysis and thematic reporting with confidence
• Master key RCA techniques favoured by leading internal audit teams worldwide
• Enhance your audit methodology to deliver robust, consistent root cause insights—recognizing that every issue has multiple root causes (typically spanning detection and prevention failures)
• Accelerate rather than slow assignments by focusing testing through RCA-informed scoping and analytics
• Unlock insight and foresight by revealing themes explaining recurring issues and enabling internal audit to champion GRC maturity
• See how AI tools can help to analyse patterns across audit findings, automatically suggest root cause categories, and generate visual causal diagrams

Course Programme

IIA Guidance and GIAS Requirements

• Decode the latest GIAS requirements and understand strategic intent

Five Essential RCA Techniques

Learn when and how to apply:

• 3-Way 5 Whys—structured questioning for complex scenarios
• Fishbone (Ishikawa) diagrams—categorical cause mapping
• Fault Tree Analysis—systematic deductive reasoning
• Bowtie Diagrams—preventive and detective control visualization
• FMEA Boundary Diagrams—process failure mode mapping
• Causal Loop Analysis—dynamic systems thinking for complex interactions

Methodology Integration

• Embed RCA into your audit methodology for consistent application
• Sharpen your scoping process to identify high-probability root causes before fieldwork begins
• Align work programs with GIAS topical requirements through causal thinking

Reporting Excellence

• Craft shorter, more impactful audit reports infused with insight and foresight
• Use AI-generated visualizations to communicate complex causal relationships clearly

Themes and RCA Categories

• Establish appropriate RCA taxonomies for effective thematic analysis
• Connect GRC best practices with root cause patterns—understand where excellence prevents problems
