Over the past decade, Object Oriented Analysis and Design (OOA&D) has become the dominant software development paradigm. With it has come a major shift in the thought processes of all involved in the software development life cycle.

Programming language support for objects began with Simula 67, but it was the emergence in the 1980's of hybrid languages, such as C++, Ada and Object Pascal that allowed OOA&D to take off. These languages provided support for both OO and procedural programming. Object Oriented programming became mainstream.

An OO system is designed and implemented as a simulation of the real world using software artifacts. This premise is as powerful as it is simple. By using an OO approach to design a system can be designed and tested (or more correctly simulated) without having to actually build the system first.

It is the development during the 1990's of tools to support Object Oriented analysis and design that moved this approach into the mainstream. When coupled with the ability to design systems at a very high level, a tool based OOA&D approach has enabled the implementation of more complex systems than previously possible.

The final driver that has propelled OOA&D has been its suitability for modeling graphical user interfaces. The popularity of object based and object oriented graphical languages such as Visual Basic and Java reflect the effectiveness of this approach.

During the 1980's a number of OOA&D process methodologies and notations were developed by different research teams. It became clear there were many common themes and, during the 1990's, a unified approach for OOA&D notation was developed under the auspices of the Object Management Group. This standard became known as the Unified Modeling Language (UML), and is now the standard language for communicating OO concepts.

ArgoUML was conceived as a tool and environment for use in the analysis and design of object-oriented software systems. In this sense it is similar to many of the commercial CASE tools that are sold as tools for modeling software systems. ArgoUML has a number of very important distinctions from many of these tools.

UML is the most prevalent OO modeling language and Java is one of the most productive OO development platforms. Jason Robbins and the rest of his research team at the University of California, Irvine leveraged these benefits in creating ArgoUML. The result is a solid development tool and environment for OO systems design. Further, it provides a test bed for the evolution of object oriented CASE tools development and research.

A first release of ArgoUML was available in 1998 and more than 100,000 downloads by mid-2001 show the impact that this project has made, being popular in educational and commercial fields.
