Abstract

Robert and Fotios discuss the results of their important new survey on the key elements for improving the quality of the forecasting function. A lot more is involved here than software and statistical methodology; it?s also about removing organizational impediments, developing appropriate performance benchmarks and motivational incentives, and improving data reliability and flow within the organization.
