标准范围

在系统和软件工程中，计算机辅助软件工程（CASE）工具代表了用于开发和维护信息技术系统的支持技术的主要部分。它们的选择必须仔细考虑技术和管理要求。ISO/IEC 14102:2008定义了一组流程和一组结构化的案例工具特性，用于技术评估和案例工具的最终选择。它遵循ISO/IEC 14598-5:19 98中定义的软件产品评价模型，ISO/IEC 14102:2008采用ISO/IEC 9126-1:20 01中定义的软件产品质量特征和子特征的通用模型，并在软件产品为CASE工具时对其进行扩展；它提供了CASE工具独有的产品特性。然后，这组更大的特征被组织成四组:与生命周期过程功能相关的特征；与案例工具使用功能相关的特征；一般质量特性；与质量无关的一般特征。这种分组为整个评估和选择过程提供了一种更易于管理的方法。技术评估可以指示CASE工具满足其用户陈述要求的程度。它还可以指示工具在多大程度上满足其声称的功能。技术评估过程的目标是提供定量结果，作为最终选择的基础。测量为实体的属性分配数字（或其他评级）；评价的主要活动是获得用于选择的这些测量值。最终评选结果应以实现客观性、可重复性和公正性为目标。这些目标和对结果的信心将部分取决于分配给总体评估和选择过程的资源。要求ISO/IEC 14102:2008的用户在早期阶段处理这些问题。为了被广泛接受，这些案例工具评估和选择过程必须对案例工具的用户以及案例的供应商和整个社区有价值。ISO/IEC 14102:2008中概述的信息应导致CASE工具的更具成本效益的选择，并使CASE工具功能和特性的描述更加一致。

Within systems and software engineering, Computer-Aided Software Engineering (CASE) tools represent a major part of the supporting technologies used to develop and maintain information technology systems. Their selection must be carried out with careful consideration of both the technical and management requirements.

ISO/IEC 14102:2008 defines both a set of processes and a structured set of CASE tool characteristics for use in the technical evaluation and the ultimate selection of a CASE tool. It follows the software product evaluation model defined in ISO/IEC 14598-5:1998.

ISO/IEC 14102:2008 adopts the general model of software product quality characteristics and subcharacteristics defined in ISO/IEC 9126-1:2001 and extends these when the software product is a CASE tool; it provides product characteristics unique to CASE tools. This larger set of characteristics is then organized into four groups:

• characteristics related to life cycle process functionality;


• characteristics related to CASE tool usage functionality;


• general quality characteristics;


• general characteristics not related to quality.

This grouping provides a more manageable approach to the overall evaluation and selection process.

The technical evaluation can indicate how well a CASE tool meets its user's stated requirements. It can also indicate how well the tool meets its claimed functionality.

The objective of the technical evaluation process is to provide quantitative results on which the final selection can be based. Measurement assigns numbers (or other ratings) to attributes of entities; a major activity of evaluation is to obtain these measurements for use in selection. The final selection results should aim to achieve objectivity, repeatability and impartiality. These objectives and the confidence in the outcomes will in part depend on the resources allocated to the overall evaluation and selection process. The user of ISO/IEC 14102:2008 is asked to deal with these issues at an early stage.To be widely acceptable, these CASE tool evaluation and selection processes must be of value to the users of CASE tools, and to the suppliers of CASE to the community at large. The information outlined in ISO/IEC 14102:2008 should lead to more cost effective selections of CASE tools and to a greater uniformity in how CASE tool functions and features are described.
