Time is an essential measure of performance in software development because time delays tend to fall directly to the bottom line. To address this issue, this research seeks to distinguish time-based software development practices: those managerial actions that result in faster development speed and higher productivity. This study is based upon a survey of software management practices in Western Europe and builds upon an earlier study we carried out in the United States and Japan (Integrated Manufacturing Systems, vol. 7, no. 2, 1996). We measure the extent to which managers in the USA, Japan and Europe differ in their management of software projects and also determine the tools, technology and practices that separate fast and slow developers in Western Europe.
