This International Standard deals with the evaluation and selection of CASE tools, covering a partial or full portion of the software engineering life cycle. It establishes processes and activities to be applied for the evaluation of CASE tools and selecting the most appropriate CASE tools from several candidates. These processes are generic, and organizations must tailor them to meet organizational needs. The CASE tool evaluation and selection processes should be viewed in the larger context of the organizations's technology adoption process. This International Standard provides: a. Guidance on identifying organizational requirements for CASE tools. b. Guidance on mapping those requirements to CASE tool characteristics to be evaluated. c. A process for selecting the most appropriate CASE tool from several tools, based on measurements of the defined characteristics. Primary users of this International Standard are organizations that intend to adopt CASE tools to support their software life cycle processes. CASE tool suppliers may also use this International Standard to describe characteristics of their CASE tools.
