Object oriented top-down software design process

Progress in software engineering theory often does not change the situation of software designers who in most cases are faced with the problem of defining their own methodology for software development. There are a few attempts to introduce formal methods for software development. One of those attempts and probably the most successful one is the object oriented approach which provides designers with well defined framework to perform system analysis and design. The main aim of the paper is not to introduce the object oriented concept and any of the notations currently being used but to propose a practical design flow which would be of help in organizing the object oriented design process. An instance of design process is presented. An example system has been analyzed with the help of OMT method and implemented in C++.
