| Software analysis and designing on an object-oriented basis have been developing for twenty years. Along with constantly improving program language, correlative criterions and techniques have been reformed, and corresponding process has been established. Thereinf application of UML, Rational Unified Process(RUP),Rational Rose and component technique make object-oriented software development trend to criterion, automatization, systematism and practicability, which attract lots of software development organizations currently.The paper systemically discusses object-oriented software development methods, and introduces correlative concepts and principles of object-oriented technique, visual modeling technique represented by UML, Unified Process in team' developing. Then, the paper proposes process management of software development methods based on hierarchy model. It hierarchies process concept and classifies complex factors to different abstract layers: organization layer, work flow layer and material layer .According to different features , corresponding measures are applied to control and improve the software development process effectively.In addition, the paper applies object-oriented technique, UML and RUP to development process of Softwave Network Monitor System, including capturing the requirement with Use Case Mode, analyzing and designing the static structure and dynamic behavior, decomposingsystem to proper granularity step by step. Finally, it realizes the system with component technique in the ultimate.
