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 easyto-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.
