Management faces the three basic challenges of achieving cost efficiency, successfully applying new technology, and minimizing risk. This paper examines the ways in which data audits can help managers come to terms with each of these challenges. It emphasizes the role of data audits in providing reliable information on which to base decisions and stresses the importance of auditing data in process rather than retrospectively. The paper examines frequently encountered sources of error and discusses the ways audits benefit management by assuring the integrity of experimental design, by preventing misassignment of observations, and by preventing the loss of data.
