Abstract

Productivity measures based on a simple ratio of product size to project effort assume that size can be determined as a single measure. If there are many possible size measures in a data set and no obvious model for aggregating the measures into a single measure, we propose using the expression AdjustedSize/Effort to measure productivity. AdjustedSize is defined as the most appropriate regression-based effort estimation model, where all the size measures selected for inclusion in the estimation model have a regression parameter significantly different from zero (p
