Controlling the Information Flow in Spreadsheets (0803.2527v1)

Abstract: There is no denying that spreadsheets have become critical for all operational processes including financial reporting, budgeting, forecasting, and analysis. Microsoft Excel has essentially become a scratch pad and a data browser that can quickly be put to use for information gathering and decision-making. However, there is little control in how data comes into Excel, and how it gets updated. The information supply chain feeding into Excel remains ad hoc and without any centralized IT control. This paper discusses some of the pitfalls of the data collection and maintenance process in Excel. It then suggests service-oriented architecture (SOA) based information gathering and control techniques to ameliorate the pitfalls of this scratch pad while improving the integrity of data, boosting the productivity of the business users, and building controls to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act.
