After confronting unprecedented challenges in the last decade, accounting firms have undertaken extensive effort to improve the basic financial statement audit and to expand external assurance beyond the traditional audit. The reexamination of audit methods has produced a new emphasis on assessing business and process risks in the conduct of an audit. This paper describes the fundamental changes in the audit process and examines their impact in an actual engagement. We first identify outcomes that we expect to observe in an audit based on the business risk model and then study an actual engagement to gather preliminary evidence about our expectations. The engagement used in this study is the 1997 audit of the Czech bank Československá Obchodní Banka (ČSOB). Important observations about the new audit process included changes to the audit team structure, changes in administration and timing of the engagement, changes in the risks addressed during the audit and the evidence gathered, increased assurance to the client, and increased opportunities for value-added services. Although the generalization of results from a field study is constrained, this study identifies expectations and effects that can be examined in future larger sample studies.
