Root cause analysis (RCA) is increasingly used in auditing as part of quality assurance systems to improve audit quality. This practice note outlines ten key considerations for applying RCA effectively in audit firms.
RCA is not about assigning blame but fostering organizational learning and continuous improvement. It emphasizes understanding human behavior, recognizing that errors and successes often share similar causes, and acknowledging the complexity of organizational contexts where multiple factors contribute to outcomes.
Effective RCA requires rigorous, evidence-based approaches, practical and measurable recommendations, and collaborative processes involving skilled professionals. Challenges include interviewing staff in high-accountability environments, managing interpersonal dynamics, and ensuring recommendations go beyond superficial fixes like training.
The note also highlights the value of analyzing near misses and positive quality events, and advocates for thematic and firm-level analyses for deeper insights. Ultimately, RCA can help audit firms align practices with societal expectations of audit quality when implemented thoughtfully and systematically.
