Customers' perceptions of the work performed by the internal audit functions in the public sector : a case study of National Treasury

Abstract

This study was conducted to generate an in-depth understanding of key internal audit function (IAF) customers’ perceptions of the work performed by the Department of National Treasury’s IAF. This study was further intended to address the absence of any qualitative study of IAF customers’ experiences and expectations, and their perceptions of the challenges the IAF faces. The study had five research objectives, namely: to identify the role of the IAF in the public sector in relation to its customers; to discuss strategies to meet the expectations of IAF customers; to determine the experiences of the identified key IAF customers of the work performed by the IAF in the National Treasury; to determine the expectations of the identified key IAF customers of the IAF in the National Treasury, and to ascertain what the identified key IAF customers perceive to be challenges facing the IAF in the National Treasury. In order to achieve the research objectives, the study implemented a qualitative research design using the National Treasury as a case study. Data were collected through semi-structured interviews with participants selected from the key IAF customers’ categories (comprising the audit committee (AC), executive and senior managers, programme and operating managers, and external auditors). Three main themes emerged from the identified key customers’ views. These were (1) Experiences, which revealed that the participants were reasonably satisfied with the work of the IAF in the National Treasury. Participants from the AC, the executive and senior managers, and the Auditor General of South Africa (AGSA) felt that the IAF does add value, while the programme and operating managers participants indicated that the IAF does not demonstrate a holistic view when it conducts evaluations. (2) Expectations, the AC participants expected the AGSA to be able to rely on the work of the IAF, that the IAF should maintain a findings register, and that it should demonstrate IT skills. Executive and senior managers participants expected the IAF to add value to the strategic direction of the National Treasury. Programme and operating managers participants expected the IAF to be open and consultative, to set realistic audit plans, to provide regular feedback, and to demonstrate knowledge of the business. The AGSA participants called for the IAF to demonstrate technical competencies as well as independence and objectivity. (3) Challenges, participants perceived the IAF’s lack of knowledge of the business, the limited reliance placed on its work by the AGSA, the lack of audit action monitoring processes and the lack of management support for the IAF as its biggest challenges. This study could benefit the National Treasury’s IAF by helping it to understand the changing needs and expectations of its customers, and to identify areas for improvement. It may also benefit professional audit bodies and the newly-established National School of Government by providing them with insights into the training needs of internal auditors, and the necessity of providing continuing professional educational programmes.
