The public value of the National Audit Office

Purpose - Supreme audit institutions (SAIs) have become increasingly active in recent years in carrying out "performance audits" of various public bodies. But how does SAIs report on their own performance? The purpose of this paper is to report on a study (commissioned by the UK National Audit Office (NAO)) of how SAIs report on their own performance and explores a possible conceptual framework - a synthesis of work on "performance regimes", "public value" and "competing values" approaches - which might provide a basis for enhancing such reporting.Design methodology approach - The paper is based first on a review of self-reporting of performance by SAIs in Australia, Canada, the USA, New Zealand and with a specific focus in more detail on the UK's NAO. In Section I, it explores existing self-reporting practices of a number of SAIs based on their published reports. Section II of this paper is more conceptual. Drawing on notions of "performance regimes", "public value" and "competing values", it seeks to re-conceptualise how SAIs in general, and the NAO specifically, might usefully report on their performance for multiple external audiences.Findings - The conclusions drawn from the first part of the paper include that multiple measures of SAI performance have evolved, including impacts on governments; financial savings; impact on parliament; media impact, etc. The second part concludes tentatively that a synthesis of "public value" and "competing values" might provide a conceptual framework for making more sense of such multiple reporting.Practical implications - The immediate practical value of this paper should be for SAIs in providing a possible framework for analysing and developing their own performance reporting policies to address multiple dimensions of achievement and meet the needs of multiple stake holders. More widely, this framework can be applied to other public agencies.Originality value - There are few, if any, current studies of comparative SAI self-reporting of performance, so this paper makes a substantial contribution in this area. The conceptual framework developed in the second half of the paper is also unique in synthesising two important streams of thinking about "public value" and "competing values" which has far wider applicability than the study of SAIs.
