The article examines a statistical analysis of a productivity variation, involving a unique database containing 206 business software projects from 26 Finnish companies. The authors examine differences in the factors, explaining productivity in the banking, insurance, manufacturing, wholesale/retail, and public administration sectors. The authors provide productivity benchmarking equations that are useful both for estimating expected productivity at the start of a new project and for benchmarking a completed project for each business sector.
