Audit procedures to assess the ability of controls to prevent or detect material misstatements Provide evidence about control risk Substantive tests Audit procedures that detect material misstatements Provide evidence about detection risk GBW 8th ed., Ch. 6

21 TESTS OF CONTROLS Procedures address questions such as
How are controls applied? Are controls applied consistently? By whom are controls applied? GBW 8th ed., Ch. 6

22 TESTS OF CONTROLS & CONTROL RISK
Tests of controls are procedures to assess control risk Assessed level control risk helps determine acceptable level detection risk GBW 8th ed., Ch. 6

33 INTERNAL LEARNING & SKEPTICISM
Issue Professional Skepticism Improved performance Poor performance against industry best practices Innovation Lagging product development GBW 8th ed., Ch. 6

34 COGNITIVE BIASES IN EVALUATING EVIDENCE
Heuristics: simplifying rules of thumb that may bias decision making Representativeness Availability Anchoring-and-adjustment GBW 8th ed., Ch. 6

35 COGNITIVE BIASES: Representativeness
Given an item, b, and a class of items, A, making a judgment based on how much b resembles other items from class A rather than making a judgment based on the probability that b came from class A. GBW 8th ed., Ch. 6

36 COGNITIVE BIASES: Availability
The decision maker evaluates the likelihood of a particular outcome based on infrequent but highly publicized outcomes rather than outcomes predicted by the profession’s collected experience. GBW 8th ed., Ch. 6

37 COGNITIVE BIASES: Anchoring-and-Adjustment
The decision maker assesses likelihood of an outcome with an initial, sometimes biased probability estimate (anchor) then adjusts the probability insufficiently when discovering new information. GBW 8th ed., Ch. 6

38 AUDIT DOCUMENTATION ASB Standards
Auditor’s judgment about nature, extent of documentation depends on Risk of misstatement Judgment about audit work Nature of procedures Significance of evidence Nature, extent of assertions tested GBW 8th ed., Ch. 6
