Leveraging Robustness Analysis for Efficient System Design

Leveraging Robustness Analysis for Efficient System Design

Introduction Robustness Analysis, initially introduced by Ivar Jacobson's Objectory Method but later excluded from the Unified Modeling Language (UML), is a valuable practice in software engineering. This method involves dissecting the narrative text of use cases to identify the primary set of objects participating in those use cases and categorizing these objects based on their roles. By doing so, robustness analysis facilitates a seamless connection between Use Cases and Domain Classes, effectively aligning with the Model-View-Control (MVC) software architecture. It's important to note that robustness analysis is not an integral component of UML…continue reading →
