Center node: "sarbanes oxley what about all the spreadsheets"
  Abstract: The Sarbanes-Oxley Act of 2002 has finally forced corporations to examine the validity of their spreadsheets. They are beginning to understand the spreadsheet error literature, including what it tells them about the need for comprehensive spreadsheet testing. However, controlling for fraud will require a completely new set of capabilities, and a great deal of new research will be needed to develop fraud control capabilities. This paper discusses the riskiness of spreadsheets, which can now be quantified to a considerable degree. It then discusses how to use control frameworks to reduce the dangers created by spreadsheets. It focuses especially on testing, which appears to be the most crucial element in spreadsheet controls.
