1 Introduction to Reference Designation System ISO/IEC 81346 Systems Engineering A/S Denmark - 2015 It s all about creating a common language semantics the meaning of words, phrases or systems ontology a list of concepts and categories in a subject area that shows the relationships between them taxonomy the scientific process of classifying things (= arranging them into groups) [Source: Oxford Advanced Learner s Dictionary, 8th edition] 2 object entity treated in a process of development, implementation, usage and disposal system set of interrelated objects considered in a defined context as a whole and separated from their environment aspect specified way of viewing an object structure part-of relation organization of relations among objects of a system describing constituency relations (consist-of / is-a-part-of) [Source: IEC/ISO 81346 -1 (2009)] 3 reference designation identifier of a specific object formed with respect to the system of which the object is a constituent, based on one or more aspects of that system [Source: IEC/ISO 81346 -1 (2009)] 4 Systems engineering Management discipline organizes the technical effort throughout the system lifecycle, including facilitating collaboration, defining workflows, and deploying development tools.

2 Technical discipline ensures that you rigorously execute a sensible development process, from concept to production to operation.
