CAN/CSA-ISO/IEC TR 14143-5:05 (R2010)

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). At the time of publication, ISO/IEC TR 14143-5:2004 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC. 1 Scope This Technical Report describes the characteristics of Functional Domains and the procedures by which characteristics of Functional User Requirements (FUR) can be used to determine Functional Domains. Two example methods for implementing these principles are provided in the Informative Annexes. Either of the methods may be used directly, or using Functional Domains defined locally by: - FSM Method to determine if a particular FSM Method is applicable to the Functional Domain(s) represented by their specific FUR; - Describing, for a given set of FUR, the Functional Domain to which the FUR belong; and - FSM Method owners and designers describing the Functional Domain(s) to which the FSM Method can be applied, as outlined in ISO/IEC 14143-1:1998. NOTE Use of the Informative Annexes to specify Functional Domains will allow comparisons of FUR from different sources and comparisons of the applicability of FSM Methods.
