Assisting novice analysts in developing quality conceptual models with UML

Systems analysts have developed conceptual models by following the object-oriented approach in the modeling technique of the Unified Modeling Language (UML). Use case-driven modeling is a popular approach employed in systems development using the object oriented method. Use case models are used in the analysis phase to capture and represent high level system requirements. A study was conducted aimed at identifying the most typical set of errors frequently committed by novice system analysts in commonly used UML artifacts. Dynamic models were used by analysts to capture system behavior through a sequence of message flows among classes and objects. The conceptual model quality framework provided a systematic way to analyze the quality of UML artifacts help produce different types of quality. Developers of CASE tools can incorporate facilities to provide guidance to novice analysts in preventing typical novice errors during the modeling process.
