INTRODUCTION • Visible Analyst is an easy-to-use Computer Aided Software Engineering (CASE) strategic planning; analysis; design; and object, data, and process modeling tool. Its powerful yet easy-to-master diagramming, analyzing, and modeling capabilities enhance not only the productivity of software developers but also the overall efficiency of software analysis, design, and modeling practices. In addition, the software’s ease of use permits people outside the traditional software development function to become involved in the development process. Even non-technical managers and system end-users are able to use Visible Analyst to effectively communicate system requirements and goals, proposed modifications, etc.
