Leaders set the tone at the top by establishing audit quality as a global priority and fostering a culture of continuous improvement. High-quality audits drive long-term value and stakeholder confidence, and EY auditors strengthen this trust by understanding a company’s financial risk profile, analyzing data objectively and independently, and applying a globally consistent audit approach.
Audit professionals across the globe play a vital role in driving quality outcomes through a culture of continuous improvement. They prioritize learning and development while fostering a culture of innovation by upskilling to be proficient in technology-driven and AI-powered audit capabilities.
With its global roll-out of enterprise-scale agentic AI in Assurance, EY is marking a fundamental shift toward AI-transformed audits. These releases, alongside a modernized audit approach, are part of a multibillion-dollar commitment to audit quality, technology and people, which will continue as part of the EY "All in" global strategy.
The EY Global Audit Methodology helps auditors interpret and apply relevant auditing standards. It is regularly optimized and standardized to help enable greater consistency in audit execution and to embrace the use of the latest technology to improve the quality of EY audits.
