本国际标准为CASE工具的评估和选择提供了指南，涵盖了软件工程生命周期的部分或全部。它建立了用于评估案例工具并从多个候选案例中选择最合适的案例工具的流程和活动。这些流程是通用的，组织必须对其进行调整，以满足组织需求。CASE工具的评估和选择过程应该在组织技术采用过程的更大背景下看待。 本国际标准规定了以下内容: a） 确定案例工具组织需求的指导； b） 关于将这些要求映射到待评估的CASE工具特征的指南； c） 根据定义特征的测量，从多个工具中选择最合适的CASE工具的过程。 本国际标准的主要用户是打算采用CASE工具来支持其软件生命周期过程的组织。CASE工具供应商也可以使用该国际标准来描述特征 他们的案例工具。 本国际标准不适用于: a） 软件工程框架，其目的是为数据、控制和表示集成提供机制； b） 可用于软件工程活动的通用工具（如文字处理器、电子表格），或范围非常狭窄或用途特殊的CASE工具（如编译器）； c） 在组织内规划案例工具的实施（尽管这是一个重要的主题）。 注:本国际标准的用户可以尽可能最好地选择CASE工具，但不能保证成功实施。 ISO/IEC TR 14471采用CASE工具解决了这个问题。 本国际标准包含一组专门定制的过程、活动和任务。裁剪过程是对适用过程、活动和任务的选择。 符合本国际标准的定义是，从本国际标准中为评估和选择项目选择的过程、活动和任务的绩效。任何组织强加这一点 作为贸易条件的国际标准负责规定构成本国际标准给定应用合规性的最低要求的过程、活动和任务。

This International Standard gives guidelines for 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 organization's technology adoption process. This International Standard provides the following: 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 can also use this International Standard to describe characteristics of their CASE tools. This International Standard is not intended to apply to: a) software engineering frameworks whose purpose is to provide mechanisms for data, control and presentation integration; b) general purpose tools (e.g. word processors, spreadsheets) which can be used in software engineering activities, nor CASE tools of very narrow scope or specific purpose (e.g. a compiler); c) planning for the implementation of CASE tools within an organization (even though it is recognised that this is an important subject). NOTE A user of this International Standard can make the best possible selection of a CASE tool and yet have no guarantee of a successful implementation. ISO/IEC TR 14471 Adoption of CASE Tools addresses this subject. This International Standard contains a set of processes, activities, and tasks designed to be tailored. The tailoring process is the selection of applicable processes, activities and tasks. Compliance with this International Standard is defined as the performance of the processes, activities, and tasks selected from this International Standard for the evaluation and selection project. Any organization imposing this International Standard as a condition of trade is responsible for specifying the minimum set of required processes, activities, and tasks which constitute compliance for a given application of this International Standard.
