Computer-aided systems engineering methodology support and its effect on the output of structured analysis

摘要: The information systems development literature indicates that there is no conclusive, empirical evidence CASE improves the quality of system specifications or resulting systems. One role a tool to serve as methodology companion—to assist an analyst in creation documentation passed succeeding phases life cycle, and guide through particular methodology. A framework for comparing level support provided by proposed applied 27 structured analysis rules. contains seven levels rule enforcement, ranging from real-time enforcement absence rule. then two popular, commercial tools. Each was used eight project teams over month period construct functional specification hotel system. goal study examine influence on each Methodology errors were noted An frequency internal consistency rules are easily adhered regardless tool, while hierarchical more frequently presence rigorous support.
