New IEEE Standard - Superseded. This standard defines a process for evaluating and selecting a Computer Aided Software Engineering (CASE) tool for a software development or maintenance activity. The standard addresses the evaluation and selection of tools supporting software engineering processes including: project management processes, development processes, and integral processes. Project purpose: The primary users of ISO/IEC 14402 are organizations that intend to adopt CASE tools to support their software life cycle processes. CASE tool suppliers may also use 14402 to describe the characteristics of their CASE tools.
