Object-Oriented Analysis, Design and Implementation | SpringerLinkObject-oriented analysis and design OOAD is a popular technical approach for analyzing and designing an application, system, or business by applying object-oriented programming , as well as using visual modeling throughout the development life cycles to faster better stakeholder communication and product quality. According to the popular guide Unified Process , OOAD in modern software engineering is best conducted in an iterative and incremental way. Iteration by iteration, the outputs of OOAD 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. In the early days of object-oriented technology before the mids, there were many different competing methodologies for software development and object-oriented modeling , often tied to specific Computer Aided Software Engineering CASE tool vendors. No standard notations, consistent terms and process guides were the major concerns at the time, which degraded communication efficiency and lengthened learning curves. Later, together with Philippe Kruchten and Walker Royce eldest son of Winston Royce , they have led a successful mission to merge their own methodologies, OMT , OOSE and Booch method , with various insights and experiences from other industry leaders into the Rational Unified Process RUP , a comprehensive iterative and incremental process guide and framework for learning industry best practices of software development and project management.
