A process for combining object oriented and structured analysis and design

While Object Oriented (OO) methodologies have some advantages over structured methods, OO is not as mature as structured analysis and design and does not contain all of the tools/ techniques needed to support a large system design. By using both OO models and Structured models (e.g., data flow diagrams, control flow diagrams, state transition tables) during systems analysis, a more complete understanding of the system requirements can be developed. During the design process, the software architecture components can be designed and built either as OO modules or structured modules depending upon the requirements of the module. Since both views of the system (OO and structured) have been built during the analysis phase there is no "translation/conversion" from one methodology to the other. By combining models and approaches from both OO and structured methods in one process we can take advantage of the strengths of both methodologies
