19、SO/IEC 14102:2008(E) iv ISO/IEC 2008 All rights reservedForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in t

20、he development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-g

21、overnmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main ta

22、sk of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a

23、 vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 14102 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information tec

25、ISO/IEC 14102:2008(E) ISO/IEC 2008 All rights reserved vIntroduction 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 ca

26、rried out with careful consideration of both the technical and management requirements. This International Standard 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

27、 product evaluation model defined in ISO/IEC 14598-5:1998. This International Standard adopts the general model of software product quality characteristics and sub-characteristics defined in ISO/IEC 9126-1:2001 and extends these when the software product is a CASE tool; it provides product character

28、istics unique to CASE tools. This larger set of characteristics is then organized into four groups. 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 users stated requirements. It ca

29、n 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

30、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

31、 user of this International Standard 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 this

32、International Standard should lead to more cost-effective selections of CASE tools and to a greater uniformity in how CASE tool functions and features are described.

34、rd 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.

35、 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 technology adoption process. This International Standard provides the following: a) guidance on

36、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 In

37、ternational 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 en

38、gineering 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

39、) 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

40、 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 a

41、s 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,

42、 and tasks which constitute compliance for a given application of this International Standard.

45、the software module, package or product 3.2 CASE tool software product that can assist software engineers by providing automated support for software life-cycle activities as defined in ISO/IEC 12207:2008 NOTE 1 A CASE tool can provide support in only selected functional areas or in a wide variety o

46、f functional areas. NOTE 2 CASE tools can be used in several modes: As stand-alone tools; in this case, only compatibility with environment elements should be addressed. In small groups that communicate directly with one another; it can be supposed that integration is predefined, perhaps proprietari

47、ly. In the presence of a larger framework of the SEE; in this case the ability of the tool to use the relevant services of the framework should be addressed. 3.3 measurement use of a metric to assign a value (which may be a number or category) from a scale to an attribute of an entity ISO/IEC 14598-

48、1:1999 NOTE 1 Measurement can be qualitative when using categories. For example, some important attributes of software products, e.g. the language of a source program (Java, C+, C, COBOL, etc.) are qualitative categories. NOTE 2 Measurement can apply to metrics other than Software quality metrics. N

49、OTE 3 An Object can be measured directly, or can be information about or representations of the Object measured indirectly by the application of metrics. 3.4 metric defined measurement method and measurement scale ISO/IEC 14598-1:1999 SANS 14102:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .ISO/IEC 14102:2008(E) ISO/IEC 2008 All rights reserved 33.5 rating action of mapping the measured value to the appropriate rating level ISO/IEC 14598-1:1999 NOTE 1 Used to de
