||Research concerning application development productivity beyond the level of programmer productivity is conspicuously sparse. Through a series of studies, we aim to build a theoretical base for future investigation of the productivity problem and its solution. We are still at the exploratory, theory-building stage of research. By presenting one phase of our research in this forum, we hope to attract the interest of other researchers to this line of investigation. We believe the development of theory concerning application development productivity has great potential for improving future practice. Specifically, I/S managers currently have a micro focus on productivity improvement. Through our studies, we hope to build evidence to convince practitioners to move to the use of macro-level methods and tools, and to have greater regard for I/S planning. In the present study, we test hypotheses derived from a previous exploratory study. We find support for the contribution of macro-level methods to application development productivity, but no support for improvement due to the use of planning. Continuing our pursuit of this issue, our next study wii revert to an exploration of factors in a different cultural setting.
