Manuscript type: Research paper
Research aims: This paper examines the impact of interactive
reviews and the effectiveness of group support system (GSS) in
mitigating information ambiguity in audit decisions.
Design/ Methodology/ Approach: The research employed a
laboratory experiment, with 74 students serving as subjects. In this
study, the following information ambiguity were manipulated: (1)
insufficient and complex data, (2) sufficient and complex data, or
(3) sufficient and non-complex data. The decision-making process
(individually and through GSS interaction) was also manipulated.
In this research, audit decisions made of the client’s internal control
system served as the dependent variable.
Research findings: Analysis shows that ambiguity level has a
negative effect on the accuracy of audit decisions. The empirical
evidence acquired suggests that GSS-based interactive review
increases the accuracy of audit decisions. It further shows that the
GSS-based interactive review can be effective and practical as a
strategy to mitigate information ambiguity in the audit decision
making process during the planning stage.

Theoretical contribution/ Originality: By investigating the benefits
of information technology as a control mechanism for the auditing
process and by looking at how it alters auditors’ behaviour and
how it enables the auditing team to behave in reviewing their
work, this study contributes to extant literature. This research fills
in the theoretical gap by using GSS to mitigate the ambiguity of
Practitioner/ Policy implication: The result of this study will
encourage auditor to use GSS as a means of communication between
the audit team leader and members.
Research limitation/ Implications: The limitation of this study lies
in its using a single leader and not other members of the audit team
to do the GSS in the experimental manipulation.
