    Title:
    Group judgment and decision making in auditing: Past and future research.
    Practical Implications:

    The insights highlighted in this paper from research on audit groups/teams inform one’s understanding of how best to design group interactions between auditors within the firm and with professionals outside the audit firm, including management, audit committees, and inspectors. These insights are important given the criticism audit firms have faced from regulators and inspectors over the past decade and the multi-person setting present in auditing. Further, while a large literature exists on single-person decision-making, these studies may not generalize to multi-person settings. The review also highlights the need for continued research in this area and the importance audit practitioner involvement with future research efforts.

    Purpose of the Study:

    This paper examines experimental research on audit groups/teams. The paper focuses on three main areas: 1) the hierarchical review process, 2) brainstorming as part of the fraud detection planning process, and 3) consultation within firms. The authors define research on audit groups/team as those papers where two or more individuals within the audit firm interact with one another face-to-face, electronically, or where on person prepares/reviews working papers for another. In addition to summarizing research to date in each of the three areas, the authors suggest directions for future research within the three areas as well as future research on within-firm group interactions. These areas include shared mental models, audit team diversity, and interactions with groups outside the audit firm, such as audit committees.

    Design/Method/ Approach:

    The paper summarizes research on group audit JDM experimental studies published in Accounting, Organizations, and SocietyContemporary Accounting ResearchJournal of Accounting Research, and The Accounting Review from 1970 through 2015. Relevant working papers are also discussed.

    Findings:

    Note: Given the breadth of this review paper, only select subsections are summarized below.

    • Hierarchical review process:
      • What performance gains result from the review process?
        • The review process generally improves audit effectiveness.
        • However, it is not always effective as biases may not be mitigated by the review process, such as the recency effect.
      • Alternative forms of the review process: Includes research on comparing reviews with and without discussion, specialized versus all-encompassing reviews, and electronic versus face-to-face reviews.
      • Effects of the preparer on the review process:  
        • Studies investigate the attributes of the preparer and the effects of preparer stylization on the review process.  
        • Overall, preparer attributes and stylization have a significant impact on the review process.
    • Brainstorming:
      • Face-to-face interacting versus nominal brainstorming: Nominal groups generate more unique ideas than face-to-face interacting groups, due to process losses (e.g., production blocking) occurring in the face-to-face interacting context.
      • Interacting face-to-face brainstorming compared to alternate brainstorming formats: While unstructured face-to-face brainstorming is the most common method used by audit firms, other methods (e.g., providing guidelines or instructions) outperform this unstructured method with respect to the quantity of fraud risks identified and fraud hypotheses generated.
      • Electronic brainstorming:  
        • Positive consequences of electronic brainstorming include minimizing production blocking and evaluation apprehension, however social loafing is a potential negative consequence.
        • Evidence supports the claim that electronic brainstorming is superior to face-to-face interaction, however as with non-electronic brainstorming, nominal electronic brainstorming outperforms interacting electronic brainstorming.
    • Consultation within firms:
      • Willingness to follow consulting advice: Auditors tend to incorporate advice received, however receiving advice can increase the tendency to follow aggressive client preferences.
      • Willingness to seek consulting advice: In general, auditors are more likely and willing to consult when related risk is high.
