IEEE DIS 24748-2-2017 pdf free download.Systems and software engineering — Life cycle management — Part 2: Guidelines to the application of ISO/IEC/IEEE 15288 (System life cycle processes).
1 Scope This part of ISO/IEC 24748 is a guideline for the application of ISO/IEC/IEEE 1 5288:201 5. It addresses system, life cycle, organizational, project, and process, concept application, principally through reference to ISO/IEC 24748-1 and ISO/IEC/IEEE 1 5288:201 5. It gives guidance on applying ISO/IEC/IEEE 1 5288:201 5 from the aspects of strategy, planning, application in organizations, and application on projects. It also provides comparison of the differences between ISO/IEC/IEEE 1 5288:201 5 and the prior versions, ISO/IEC 1 5288:2008. This document is intended to be consistent with both ISO/IEC 24748-1 and ISO/IEC/IEEE 1 5288:201 5 in its treatment of life-cycle concepts and systems engineering processes. 2 Terms and definitions For the purposes of this document, the terms and definitions given in ISO/IEC/IEEE 1 5288:201 5 apply. 3 Overview of ISO/IEC/IEEE 15288:2015 3.1 General ISO/IEC/IEEE 1 5288:201 5 Systems and software engineering – System life cycle processes, establishes a common framework for system life cycle processes, with well-defined terminology, that can be referenced by any party, particularly those having any involvement or interest in the system life cycle or performance of systems engineering activities. It applies to the acquisition of systems, which can be comprised of products, services, or both, as well as to the supply, development, operation, maintenance, and disposal of systems, whether performed internally or externally to an organization.
NOTE 2 The management of the transition from one stage to another (not necessarily a linear, sequential, progression) and the engineering activities associated with providing appropriate work products and decision-making information are described in Clauses 3.2, 4 and 5 of ISO/IEC 24748-1 . A number of enabling systems are deployed throughout the system life cycle to provide the system-of-interest with support as needed. Each life cycle stage can require one or more enabling systems. It is important to note that an enabling system has its own life cycle and that when ISO/IEC/IEEE 1 5288:201 5 is applied to it, it then becomes a system-of-interest. NOTE 3 The role and use of enabling systems are described in Clauses 5.3.4 and 5.7.4.6 of this document. NOTE 4 For related material on enabling systems, see also Clause 5.2.3 of ISO/IEC/IEEE 1 5288:201 5 and Clause 3.1 .5 of ISO/IEC 24748-1 . ISO/IEC/IEEE 1 5288:201 5 is applicable at any level of the structure associated with a system-of-interest. As a system is decomposed recursively into its system elements, the processes of ISO/IEC/IEEE 1 5288:201 5 may be used for each system and system element in the system structure, including enabling systems. Each system and system element has a life cycle of its own and its own set of enabling systems. NOTE 5 For related material on system structure, see Clause 5.2.2 of ISO/IEC/IEEE 1 5288:201 5 and Clause 3.1 .4 of ISO/IEC 24748-1 . In order to perform needed operations and transformations upon systems during their life cycles, the organization creates and monitors projects. Projects have defined scope, resources (including time) and focus. The scope can involve managing all of the stages of the life cycle, a subset of the stages, one or more defined processes or one or more process activities. The time scale can be of varying duration, for example one hour or tens of years.
Organizations focus on systems that are created or transformed by projects within the organization or in conjunction with other organizations. Projects have a span of interest that includes the system-of-interest and its related enabling systems. Some enabling systems are under direct control of the project. The system-of- interest and those enabling systems make up the project span of control. The work performed by projects is on or with the system-of-interest within one or more life cycle stages. ISO/IEC/IEEE 1 5288:201 5 includes the requirement to define an appropriate life cycle for a system, the selection of processes to be applied throughout the life cycle and the application of these processes to fulfil agreements and achieve customer satisfaction. ISO/IEC/IEEE 1 5288:201 5 can be applied to all types of product- or service-focused systems and system elements consisting of one or more of the following: hardware, software, humans, processes, procedures, facilities, and naturally occurring entities. The use of ISO/IEC/IEEE 1 5288:201 5 for systems within this broad scope is one of its main advantages. The use of the standard may be adapted to accommodate the varying project requirements in treating system life cycles. NOTE 7 This may be performed by adapting the life cycle as described in Clause 5 of ISO/IEC 24748-1 and tailoring described in Annex A of ISO/IEC/IEEE 1 5288:201 5.
