This website discusses Object Oriented Analysis, OO Problem Analysis, Project Life Cycle, System Object Requirements, and the Unified Modeling Language.
Object-oriented analysis and design (OOAD) is an approach to analyzing and designing a system, or business by applying the object-oriented paradigm throughout the development life cycles to foster better stakeholder communication and product quality.
According to the Unified Process, OOAD in modern software engineering is best conducted in an iterative and incremental way.
Iteration by iteration, the result of Object-oriented analysis and design activities, analysis models for OOA and design models for OOD respectively, will be refined and evolve continuously driven by key factors like risks and business value.
