Object-oriented analysis and design (OOAD) is an approach to analyzing and designing a computer-based system by applying an object-oriented mindset and using visual modeling throughout the software development process. It consists of object-oriented analysis (OOA) and object-oriented design (OOD) – each producing a model of the system via object-oriented modeling (OOM). Proponents contend that the models should be continuously refined and evolved, in an iterative process, driven by key factors like risk and business value. OOAD is a method of analysis and design that leverages object-oriented principals of decomposition and of notations for depicting logical, physical, state-based and dynamic models of a system. As part of the software development life cycle OOAD pertains to two early stages: often called requirement analysis and design. Although OOAD could be employed in a waterfall methodology where the life cycle stages as sequential with rigid boundaries between them, OOAD often...
