ISO/IEC 15414:2015规定: a） 一种由概念、结构和规则组成的语言（企业语言），用于从企业的角度（如建议ITU-T X.903 | ISO/IEC 10746-3所定义）开发、表示和推理ODP系统规范； b） 建立企业语言和其他视点语言之间的对应关系的规则（定义见建议ITU-T X.903 | ISO/IEC 10746-3），以确保规范的整体一致性。 该语言的详细程度足以确定任何建模语言是否符合本建议|国际标准，并确定新规范技术的要求。 ISO/IEC 15414:2015旨在用于编制ODP系统的企业视点规范，以及开发支持此类规范的符号和工具。 如建议ITU-T X.903 | ISO/IEC 10746-3第5条所述，企业视点规范定义了ODP系统的目的、范围和政策。 ISO/IEC 15414:2015是对建议ITU-T X.903 | ISO/IEC 10746-3第5条和第10条的细化和扩展，但并未取代它们。

ISO/IEC 15414:2015 provides: a) a language (the enterprise language) comprising concepts, structures, and rules for developing, representing and reasoning about a specification of an ODP system from the enterprise viewpoint (as defined in Rec. ITU-T X.903 | ISO/IEC 10746-3); b) rules which establish correspondences between the enterprise language and the other viewpoint languages (defined in Rec. ITU-T X.903 | ISO/IEC 10746-3) to ensure the overall consistency of a specification. The language is specified to a level of detail sufficient to enable the determination of the compliance of any modelling language to this Recommendation | International Standard and to establish requirements for new specification techniques. ISO/IEC 15414:2015 is intended for use in preparing enterprise viewpoint specifications of ODP systems, and in developing notations and tools to support such specifications. As specified in clause 5 of Rec. ITU-T X.903 | ISO/IEC 10746-3, an enterprise viewpoint specification defines the purpose, scope and policies of an ODP system. ISO/IEC 15414:2015 is a refinement and extension of Rec. ITU-T X.903 | ISO/IEC 10746-3, clauses 5 and 10, but does not replace them.
