TECHNIQUES FOR THE COMPARATIVE ANALYSIS OF DATA FLOW DIAGRAMS

Abstract

This paper presents an analytic framework for comparing data flow diagrams based on five dimensions: control points, process automation, data aggregation, resource usage, and raw counts. Our goal was to develop some simple quantitative metrics that are appropriate for computer-aided system development tools. In addition, we argue for computer-aided tools that support the tandem development of alternative system diagrams. Simultaneous development of competing system descriptions may allow for more accurate contrasts and insightful analysis. Finally, we use two case studies to illustrate the comparison techniques.
