EY was looking for new digital solutions and tools to better understand and support their clients during the external audit process. This includes more complete audit coverage and better identification of audit risks and possible compliance breaches leading to fines.
In parallel, the audit industry is moving towards adopting more sophisticated audit methods: “Auditing and regulation are becoming more concerned with behavior, rather than purely concentrating on the numbers.”
