  6. Audit procedure • Audit procedure is the detailed instruction that explains the audit evidence to be obtained during the audit. • Audit procedures often incorporate sample size, items to select, and timing into the procedure.

  8. Specify the characteristics that determine the persuasiveness of evidence. Learning Objective 3

  9. Persuasiveness of Evidence The two determinants of the persuasiveness of evidence are appropriateness and sufficiency, which are taken directly from the third standard of field work. • Appropriateness • Sufficiency

  10. Appropriateness • Appropriateness of evidence is a measure of the quality of evidence, meaning its relevance and reliability in meeting audit objectives for classes of transactions, account balances, and related disclosures. • If evidence is considered highly appropriate, it is great help in persuading the auditor that financial statements are fairly stated. • 1.Relevance of Evidence 2.Reliability of evidence

  11. Relevance of evidence • Evidence must pertain to or be relevant to the audit objective that the auditor is testing before it can be appropriate.

  13. Relationships Among Audit Evidence and Persuasiveness Audit Evidence Decisions Qualities Affecting Persuasiveness of Evidence Audit procedures and timing Appropriateness Relevance Reliability Independence of provider Effectiveness of internal controls Auditor's direct knowledge Qualifications of provider Objectivity of evidence Timeliness When procedures are performed Portion of period being audited Sample size and items to select Sufficiency Adequate sample size Selection of proper population items

  14. Persuasiveness and Cost In making decisions about evidence for a given audit, both persuasiveness and cost must be considered. The auditor’s goal is to obtain a sufficient amount of appropriate evidence at the lowest total cost.
