18、tional Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fiel

19、ds of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a j

20、oint 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 task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical commit

21、tee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. In exceptional circumstances, the joint technical committee may propose the publication of a Technical Report of one of the following t

22、ypes: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an I

23、nternational Standard; type 3, when the joint technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example). Technical Reports of types 1 and 2 are subject to review within three years of publication, t

24、o decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.

27、s reserved vIntroduction Historically, there have been problems experienced by organisations in adopting CASE (computer aided software engineering) tools. Because organisations have not gained the expected benefits of CASE technology, it is hoped that the use of a well-founded CASE adoption process

28、will help achieve successful adoption of CASE tools. A survey conducted by ISO/IEC JTC1/SC7/WG4 (See Annex A: Analysis of CASE adoption questionnaire) offers some hope that these problems may be improving. This survey suggests that CASE tools are performing new capabilities and getting easier to use

29、, that users expectations are getting more sophisticated, and that CASE tools are more likely to meet their goals. However, according to the survey, there remain a number of continuing problems. There has not been sufficient attention given to pilot trials of CASE technology before using it on actua

30、l projects, and users report a need for additional top management support, a total process for CASE adoption, and a preparation of the organisation for the introduction of the technology. This Technical Report addresses the continued needs reported by users. The purpose of this Technical Report is t

31、o provide a recommended practice for CASE adoption. It provides guidance in establishing processes and activities that are to be applied for the successful adoption of CASE technology. The use of this Technical Report will help to maximise the return and minimise the risk of investing in CASE techno

32、logy. However, this Technical Report does not establish compliance criteria.

ISO/IEC 2007 All rights reserved 1Information technology Software engineering Guidelines for the adoption of CASE tools1 Scope Since CASE adoption is a subject of the broader technology transition problem, this Technical Report addresses the adoption practices appropriate for a w

34、ide range of computing organisations. This Technical Report neither dictates nor advocates particular development standards, software processes, design methods, methodologies, techniques, programming languages, or life-cycle paradigms. This Technical Report will: identify critical success factors (C

35、SF); propose a set of adoption processes; guide successful adoption in consideration of organisational and cultural environment. The following groups are targeted as potential audiences: CASE users; information systems managers; chief information officers (CIO); CASE suppliers; software engineering

36、consultants; those involved in the acquisition of CASE tools and technology. Therefore this Technical Report addresses aspects of CASE tools adoption. It is best used with ISO/IEC 14102 for CASE tool evaluation and selection. It is complementary to related ISO/IEC documents which deal with the gener

37、al aspects of these topics.

38、 definitions For the purposes of this document, the following terms and definitions apply. 2.1.1 successful adoption extent to which the use of CASE tools can measurably meet an organisations uniquely defined adoption goals 2.1.2 adoption process set of activities by which an organisation brings CAS

39、E tools into widespread use 2.1.3 CASE needs organisational requirements which are met by CASE tool characteristics NOTE These characteristics are detailed in ISO/IEC 14102:1995. They include management process, development process, maintenance, documentation, configuration management, quality assur

40、ance, verification, validation, environment needs, CASE tool integrability, quality characteristics, acquisition needs, implementation needs, support indicators, and certification requirements. 2.2 Abbreviations CASE computer aided software engineering CSF critical success factor 3 Critical success

41、factors (CSF) for adoption One of the primary goals of this Technical Report is to identify major factors which are critical to success in CASE adoption. A comprehensive set of technical, managerial, organisational, and cultural factors should be considered in order to successfully introduce CASE te

42、chnology into an organisation. These factors should be monitored through the adoption processes when applicable. A cross reference table for the processes and the factors is provided in Annex B. The following critical success factors are to be considered and evaluated. a) Goal setting: The definitio

43、n of a clear, measurable set of goals and expectations for CASE adoption, including both business and technical goals. NOTE 1 Examples of measurable set of goals for CASE adoption might be “twenty percent increase of productivity in unit test activity”, “sixteen percent improvement of quality in req

44、uirements specification activity”, “fifty percent gain of reusability in object oriented design activity”, “sixty percent of projects should use CASE tools”, etc. b) Management support: The extent to which high level management actively encourages CASE adoption, including but not limited to the will

45、ingness to allocate the necessary resources.

46、ol use. NOTE 2 Examples of strategy might include tool use on a specific set of application types, use by a specific business component or corporate-wide use. d) Total adoption process plan: A plan and design for the total process of bringing the tool into the organisational component. e) Engagement

47、: The extent to which the people involved in the adoption effort become active, motivated participants. f) Methodology adjustability: The willingness and technical feasibility of adjusting, as necessary, existing organisational methods and typical methods of using the CASE tool so as to arrive at a

48、single consistent set of methods. NOTE 3 For example, existing process-oriented methods and candidate object-oriented programming tools might not be adjusted as a single consistent set of methods. g) Training: Provision of the training and information necessary and appropriate at each step for each

49、person involved in the adoption process. h) Expert support: Provision of enthusiastic, expert tool use support during the pilot project and continuing as the tool moves into routine use throughout the organisational component. NOTE 4 The experts (or champions) assigned to the pilot project, as a group, should have a combination of skills, including capability of being proponents for the new technology, experience in the tool use, experience in the process and procedures of the organisation, and influence
