In the context of internal auditing, when there is no obvious correlation between auditors’ activities and financial
performance, it is critical to identify areas where value is added as well as the drivers that enable this, in the
evaluation of the effectiveness of the internal auditing function (IAF). This paper addresses whether and how
internal auditing activities (IAAs) can add value to their organisations. In order to gain some understanding of
value-adding processes, we analysed the responses of more than 1,800 internal auditors to questions specifically
designed to evaluate this contribution. This sample was based on the 2010 global survey of the internal auditing
profession that the Institute of Internal Auditors Research Foundation (IIARF) carried out; only those respondents
were included whose role showed they were in a position to make decisions and influence the work of their IAF.
This study found evidence that four variables are positively associated with adding value: IAF independence and
objectivity; compliance with the Institute of Internal Auditors’ (IIA) Code of Ethics; the IAF’s contribution to the
evaluation of the effectiveness of internal control; and the IAF’s contribution to the evaluation of the effectiveness
of risk management. With the exception of independence and objectivity, the analysis reveals that the remaining
value drivers of the IAF’s activities vary between developed and emerging countries and between financial and
non-financial companies, suggesting that the factors influencing the IAAs’ effectiveness might be partially context
dependent.

INTRODUCTION
The objective of this study is to explore the potential
contribution of internal auditing activities (IAAs) to
value-adding processes and to identify the main factors
associated with these activities. The study is based on the
latest in the series of surveys of members of the Institute
of Internal Auditors (IIA), known as the Common Body of
Knowledge (CBOK). These began in 1972 and have been
repeated at regular intervals ever since. The purpose of
the CBOK surveys is to investigate the factors that
influence the working practices, rationales and capability
of internal auditing functions (IAFs) in all sectors across
the world. This database is recognised as the most
comprehensive survey on the state of the internal
auditing profession world-wide.
Some scholars (e.g., Chambers, Selim & Vinten, 1987)
have argued that ‘internal audit does not exist as a divine
right’. Rather, its raison d’être is its value-generating
capability: The perception and measurement of its ability
to add value are therefore fundamental elements in
evaluating internal auditing’s role in making a significant
contribution to organisational performance. While
adding value has always been perceived as a key factor
in evaluating the need for an IAF, many organisations
are experiencing a reduction in their revenues and
profitability in the post-financial crisis environment.
There are strong pressures on senior management to
ensure that their IAAs’ added-value contribution is clear
and measurable. Prior studies (Bou-Raad, 2000; Roth,
2000; Mihret & Woldeyohannis, 2008; Barac, Plant &
Motubatse, 2009; Chen & Lin, 2011) have attempted to
identify the main drivers that might enhance value
creation processes. These studies show mixed results
with no clear dominant model. Some common value
drivers, such as the characteristics of the organisational
environment in which the IAF
1
is located, the way
it is managed and the skills and competencies of the
individuals performing the internal auditing
engagement, have been identified. These studies are
limited to single countries and are based on a small
sample; the results are therefore likely to have only
limited generalizability (Roth, 2000; Mihret &
Woldeyohannis, 2008; Barac et al., 2009).
In comparison, this study is based on responses from
more than 1,800 internal audit leaders, extrapolated from
a database that includes 13,582 responses of internal
auditors working in 107 countries who participated in the
CBOK survey in 2010. The respondents work in
organisations of different sizes, in different industries
with a differing range of activities and are members and
associates of the Institute of Internal Auditors (IIA).
Similar to the studies mentioned above, we explore
several factors associated with internal auditors’
capability to add value to their organisation by analysing
the responses of those survey participants who are
leaders of internal auditing services. Our analysis
addresses both micro- and macro-findings and we are
confident that our conclusions are generalizable.
Similar to various studies on IAA effectiveness and
value-adding capabilities (Lenz & Hahn, 2015), this paper
addresses the supply-side perspective, with internal
auditors self-assessing their capability to add value,
describing the characteristics of IAFs and the roles they
play in their organisations.

According to the definition provided by the IIA in the
International Professional Practice Framework (IPPF),
IAAs add value when they contribute to governance, risk
management (RM) and the effectiveness and efficiency of
control processes (IIA, 2013). This definition forms the
basis of the research hypotheses posited to investigate the
relationship between IAAs perceived to add value and
the IAF’s characteristics drawn from the extant literature.
