The judgment and decision-making literature in auditing largely focuses on individual auditor judgments. However, auditors do not work in isolation. They interact with other auditors in audit engagements and with other participants in the financial reporting process. For this reason, scholars have called for more research on how the people, tasks, and environment that auditors interact with influence their performance and hence, the audit quality of their work. This review identifies three specific issues related to these influences that, we believe, warrant additional research and consideration. The first two issues relate to between-auditor interactions within the audit firm. The third issue relates to interactions with groups outside the firm.  
As a key attribute to audit quality, regulators specify that more experienced staff (i.e. managers, senior auditors) should provide less experienced staff with appropriate coaching and on-the-job training (IAASB 2014). It is fairly common for junior auditors to start their auditing career by mimicking a more senior person who performs similar tasks; as the saying goes, “Monkey see, monkey do” (Cannon, 2016). Yet, while imitation is an inherent human tendency, limited evidence exists on the impact of such imitative behavior on the quality of an individual auditor’s judgment. The objective of our research project is to examine the extent to which mimicking behavior occurs in junior–senior auditor relationships and its consequences for audit quality. In particular, we advance the argument that this imitation tendency may lead junior auditors to follow seniors’ auditing practices, even when those practices are not always ideal. We also examine whether promotion opportunities for the junior can be an important contributor in mimicking an audit style of a senior (which in turn would affect audit quality). The tendency to imitate their senior – even though his working practices might not be ideal – might be higher when the direct senior has a strong voice in the promotion decision of the junior.  
KEY TAKE-AWAYS Imitation of senior auditors might be a valuable strategy for juniors to learn on-the-job and improve their performance. In this paper, the research team experimentally examines how a senior auditor’s working style (high diligence vs. low diligence) interacts with the nature of the audit firm’s promotion system (superior-based vs. consensus-based) to influence junior auditor judgment by affecting junior auditors’ imitation behavior.  
Context: Audit firms rely heavily on their intellectually skilled auditors, who manage and lead the engagement team (so-called ‘lead auditors’ in this project). To deliver high-quality audit services to their clients and to offer opportunity for auditors to learn, audit firms should try to achieve proper matching between their clients and the auditors based on compatibility between them. Appropriate matching can constitute a difficult exercise as both the lead auditors and clients may have an important stake that encourages them to intervene in the allocation process. Such interventions may affect the level of audit quality that the audit firm is able to deliver when clients and auditors are not appropriately matched. Objective and method: The objective of this research is to understand how audit firms determine the lead auditor-client pair in terms of appropriate matching. Given that such allocations take place in a work environment where lead auditors and clients have their own demands and as such can intervene in this process, this research further aims to identify the lead auditors’ motivations for intervening in this process. We will conduct semi-structured interviews with lead auditors and planning department staff of audit firms to address our research questions. Contribution: This research aims to open the ‘black box’ of audit firms’ human resources management strategies by zooming in on the process of lead auditor-client matching. Given the potential impact that proper matching between auditor and client has on audit quality, understanding the allocation process in terms of which auditor is assigned to which client is important to academic research and practice. Our research could give audit firms and audit regulators guidance for regulation and best practices when it comes to workload management.
In hierarchically structured audit teams, it is common that junior auditors gather a large part of the evidence used as the basis for the audit opinion, which makes information sharing critical. However, if a team consensus already exists, individual auditors may conform to the team and thus hesitate to raise important issues they themselves acquired about a client. This study experimentally investigates how the origin of team consensus (i.e. consensus coming from junior members vs. consensus coming from senior members) and the type of the inclusive climate (i.e. authenticity vs. belongingness) impact junior auditors’ conformity behavior and their willingness to share their own risk assessment with their team. Drawing on conformity theory, we hypothesize and find that junior auditors are more likely to conform to a team consensus of senior members, and are also less likely to share their risk assessment with the team, particularly within an authenticity climate. These effects of conforming more to senior members, however, are mitigated when firms focus on a climate of belongingness.
On June 5 2020, Eddy Cardinaels and Kristof Stouthuysen presented an online masterclass concerning their study ‘The Impact of Auditor Interactions on Audit Quality’. This report provides a summary of the masterclass, including preliminary findings from the experiment they conducted. The study, so far, shows that:
  • Concerning imitation, junior auditors imitate a more diligent superior more than a lower diligent superior. This effect is even more pronounced under a superior-based promotion system (as opposed to consensus-based promotion system).
  • Regarding audit quality, junior auditors perform better when facing a diligent superior.
Furthermore, (self-reported) imitation does not improve audit quality. In particular, when facing a low diligent auditor, audit quality deteriorates. Hence, there seems to be a possibility to imitate a superior too much, particularly in the low diligent situation.
While the allocation of human resources in audit firms is an important research topic, it has received scant research attention to date. Ideally, when audit firms aim at improving audit efficiency and effectiveness, audit firms should properly assign their clients to auditors who manage and lead the engagement team (so-called ‘lead auditors’ in this project) based on the auditor’s expertise level, industry specialization and other relevant factors that benefit audit efficiency and quality. However, lead auditors and clients alike may have their own preferences whereby they try to intervene in the allocation process. These interventions may hamper audit quality and efficiency because other factors than proper matching enter into the allocation process. Prior research on workload allocation mainly focuses on the allocation of audit hours to specific audit engagements across staff ranks and how time pressure related to audit assignments may deteriorate audit quality. Only few studies explore the workload allocation process in terms of assigning clients to lead auditors and the consequences of this assignment for audit quality. Our project focuses on a number of factors related to the allocation of lead auditors within the audit firms.

On June 21, 2021, the Foundation for Auditing Research (FAR) organized its annual conference. Forced by the global health conditions the conference was organized online. That did not stop professionals and practitioners from signing up, for we welcomed 200 audit research enthusiasts, from all over the world. The audience was comprised of 50 percent academic researchers, 35 percent were practicing auditors and the other 15 percent were a mix of regulators, standard setters, and other interested parties.

The conference consisted of four sessions. The first three presentations were related to FAR studies. The fourth study was about a recent integrity study, based on American data.
The overarching theme of the conference was ‘The Human Factor’, stressing the important fact that human influence can lead to both improvements as well as deterioration of audit quality.

In this paper, we investigate gender differences in the workload allocation process. Using a sample of 3,747 partner-year observations and 107,192 firm-year observations from Belgium, we find that female partners are associated with lower levels of workload in terms of the number of clients they serve. Our results also show that female partners audit fewer new clients. We find that the gender effect on workload is particularly strong for partners in the earlier stages of their careers. For experienced partners, we do not find gender differences in their workload, suggesting that differences between males and females in terms of workload eventually disappear. Further, we find that female auditors have clients with higher audit quality, but when controlling for workload this effect becomes smaller and even disappears in the full and Non-Big 4 sample. Our results suggest that differences in the workload allocation process can be a contributing factor to different levels of audit quality that female partners provide compared to their male counterparts. That is male auditors audit significantly more clients, which may constitute a risk factor for the audit quality they provide.

Audits do not happen in a vacuum. They are co‑produced by auditors and governance actors. In practice, how these actors set expectations, handle unforeseen circumstances, and interact with one another often determines whether high audit quality is attainable. This practice note—based on interviews with experienced auditors—seeks to demystify how relational drivers shape audit quality. We highlight five findings and invite auditors and governance actors to share their views based on these initial insights.
