The portfolio of knowledge required by industry specialist auditors

While a number of studies have shown the superior performance of industry specialist auditors, prior research has not examined the underlying knowledge categories reflective of a specialist. This study aims to identify the range of knowledge required to be a successful industry specialist auditor, and the ways in which this knowledge is and might best be acquired. A multi-method approach was employed, including the use of a free-list task to identify important categories of knowledge, and a structured questionnaire. The questionnaire examined several issues including current knowledge of specific items, extent to which specialist knowledge is reflected in the firm's support systems, and methods by which this knowledge was, and could be, acquired. Participants, designated insurance industry specialists from a Big 4 firm, identified a large range of knowledge items, and there was a large degree of consensus between the results arising from the two knowledge identification research methods utilised. The results also revealed a number of perceived deficiencies in the level of current knowledge and the extent to which specialised knowledge is reflected in support systems. Few differences were found in the knowledge requirements of the two industry sub-specialisations, life insurance, and property and casualty insurance. Except for industry and economic factors, on-the-job experience was found to be the most prevalent method of gaining industry specialist knowledge. However, there was support for greater formal training and improved firm support systems for several specific knowledge items.
