For practice, the authors provide evidence about the relation between control deficiencies and substantive tests in the integrated audit. A significant minority of senior auditors attempt to identify bias in an accounting estimate with increased sampling from the biased estimation process, though they have been told that the estimation process is biased. The authors provide theory consistent empirical evidence that auditors often reach questionable, optimistic judgments about the capability of audit evidence to address control deficiencies. Auditors will often revert to what they know best, and it is difficult to get people to look beyond the familiar, regardless of experience level.

In the planning phase, the PCAOB and key stakeholders should consider developing an ICOFR audit risk model to serve as a conceptual planning and evaluative model. Audit firms should pay attention to aligning auditors’ skill sets to their task assignments and employ other mechanisms that encourage consultations.
Scoping decisions remain underexplored. Nevertheless, anecdotal evidence suggests that auditors may be cognitively wired to scope some types of ELCs but not others. Firms may consider the interactions between auditors and client personnel that explain the tendency for auditors to evaluate only the ELCs scoped by the client.
Audit firms should pay special attention to how audit teams design testing plans to test ELCs that are not easily tested by attribute sampling methods (e.g., management philosophy and operating style). This is necessary to address concerns by PCAOB inspections that some auditors identified ELCs that appeared to be designed to operate with a high degree of precision, but failed to obtain sufficient audit evidence of their operating effectiveness.
In the evaluation phase, firms should consider mechanisms that can help auditors “imagine what could go wrong where nothing wrong has happened.” Examples of such mechanisms include restructuring the task (e.g., documentation, decomposition of the task, or requirements to list what could go wrong). In the reporting phase, firms should consider having a requirement to specifically require auditors to consider the needs of a prudent official. This requirement may be a countervailing check on their detection and disclosure incentives.

The authors note a couple of implications for practitioners resulting from this study. First, given the fact that external auditors assess internal audit quality and rely upon the work similarly for outsourced and cosourced internal audit functions, it may be worthwhile for companies to consider engaging some level of independent outside service provider to work along with their in-house internal auditors for high risk areas.
Second, having the same 3rd party internal audit service provider also provide tax services results in less reliance upon the work performed by internal audit, even though those services are approved by the audit committee and performed by different individuals. Therefore, external audit increases their audit effort, thereby implying that external audit must see this additional service provision to be detrimental to the internal audit service provider’s objectivity.

The extent to which auditors’ judgments are persuaded by information from management represents asignificant issue for audit practice, especially when information from more objective sources is also available. The evidence indicates that less experienced senior auditors rely on information from management that is aligned with management’s self-interest to a greater extent than more experienced audit seniors. This reliance raises a concern that some senior auditors assess audit evidence more favorably than may be warranted because they inappropriately rely on information provided by management. A lack of appropriate skepticism has the potential to make audits ineffective and expose the firm to audit failures. The study suggests the importance of carefully assigning audit tasks to auditors with an appropriate level of experience.

The results of this study suggests that external auditors place more reliance on “outsourced” internal audit work, especially under high inherent risk conditions, than on “in-house” internal audit work due to the external auditors’ assessment of higher objectivity on the part of the “outsourced” internal auditor. The authors suggest this may have implications for external audit teams’ planning and assessment of internal audit work, in that whether or not the work is outsourced might need to be considered in the assessment. Also, audit clients might consider a need to outsource more internal audit work or try to make changes to increase the external auditors’ perception of their “in-house” internal audit team, in terms of objectivity.

The results suggest that auditors’ AIS expertise can play a significant role in complex AIS settings and in their ability to compensate for CAS competence deficiencies. The authors note that it may be prudent for firms to consider the combined capabilities of individuals when assigning auditors and CAS to engagements with complex AIS.

The points noted below suggest some limitations in Glover, Prawitt & Wood (2008) article. However, Messier acknowledges that the article provides insight on some factors that might affect the external auditors’ reliance decisions under AS 5.
