A total of 20 papers were gathered, all having focused on
Internal audit quality and all of them are quantitative in nature. Each of the
research paper was representing some determinants of internal audit Quality,
and also the importance of internal audit function in an organisation
Mihret and Yismaw (2007) found that internal audit
effectiveness is intensely in?uenced by internal audit quality and management
support, however organizational setting and auditee traits do not have a solid
impact on audit efficiency. As the study was a case study so the
generalizability of the results is limited. Further research could be initiated
to fully understand the level of internal audit effectiveness in the Ethiopian
public sector as well as its private sector, and convincingly de?ning the
variables upsetting internal audit effectiveness in Ethiopia.
Schneider (2009) ?nds that probability of ?nding de?ciencies
impact internal audit work in some cases. But economic motivations such as
being ?red for creating poor planning decisions are absent in the paper.
Matarneh (2011) indicate that internal auditors in banks
consider the objectivity, competence and performance of internal auditors as
significant factors affecting the internal audit quality. This study
focused only on a particular bank also the variables are limited.
Salehi and Husini (2011) reveal that IT helps Auditor to improve
their performance. IT enables auditors to perform their duties with a higher
validity. But as the technology is so vast so the future studies could
investigate the side effects of use of technology in auditing process.
Stewart and Munro (2011) indicate that both factors affect
external auditors’ dependence on work already started by internal audit and their
use of internal auditors as helpers. The results also indicates that external
auditors are more likely to use internal audit for control appraisal tasks than
for functional tests of balances.
ONDIEKI (2013) revealed that there was greater change in
financial performance of commercial banks due to variations in internal audit
standards, independence of internal audit, professional competency and internal
control, this indicates that fluctuations in financial performance of
commercial banks could be accounted for by changes in internal audit
principles, independence of internal audit, professional competency and
internal control. further study to be conducted to define the challenges facing
internal audit in commercial banks, this will help in improving the internal audit
in the commercial banks and thus surely affecting their performance.
Deribe and Regasa (2014) indicate that internal auditors in
commercial banks consider the competence, performance and use of information
technology by internal auditors as substantial factors upsetting internal audit
quality. As a descriptive and regression result shows “performance” is the
highest cause factor of internal audit quality, tailed by “competence” and
“Information technology” respectively. This study concentrated only on the
banking sector, The survey study carried out and this study was concentrated on
Baharud-din, Shokiyah and Ibrahim (2014) showed that there
were significant positive relationships between the auditor competency,
auditors’ independence and objectivity and management support to the
effectiveness of internal audit. The study was concentrated only on the banking
Alzeban (2014) show a positive association between
individualism and the quality of internal audit, showing that internal audit is
largely based on the undertakings of the individual internal auditors related to
the process. Evidence was found that organizations, in which power distance and
uncertainty avoidance are high, are characterized by lower quality or internal
audit. The study is limited to the fact that only three cultural dimensions are
taken into consideration, implication of this study is only in Saudi Arabia as
the culture is different in other countries/areas.
Matari, Swidi and Fadzil (2014) revealed a significant association
between qualification of internal auditor and firm performance. That study also
indicate that There is a notable absence of research in developed as well a
developing nations concerning the direct association of internal audit function
and firm performance.
Dahir and omar (2016) found that combination of internal
audit independence, internal audit quality, internal control system and audit
risk assessments causes variation in the organizational performance of the
Endaya and Hanefah (2016) indicate that internal auditor’s
characteristics are clearly and significantly linked to internal audit
effectiveness, and senior management support is very vital in this relationship
Muchiri and Jagongo (2017) shows that internal auditing shows
a major role in the financial performance. The author found that the
relationship between the internal audit function existence and financial
performance was insignificant. That is, presence of internal auditing does not have
impact the profitability and return on investment.
