A significant problem facing information systems managers is the choice of a methodology for describing system requirements. There are certain limitations to methodologies in common use. The problem is compounded by the recent introduction of Computer Aided Software Engineering (CASE) Tools. Purchasing such a tool often requires an initial commitment to a methodology. Focusing on the diagraming phase of Requirements Definition, a comparison framework is rigorously developed Two diagraming techniques are selected and tested in an educational setting. Since the experiment was replicated during several semesters, it falls into the category of meta-analysis. Experimental outcomes are sufficiently significant to suggest possible causation. CASE tools provided more support for output quality and ease of learning for the technique that was more rule-oriented.
