标准范围
This document is a guideline for the application of ISO/IEC/IEEE 12207:2017. This document establishes
guidance to implement a common framework for software life cycle processes, with well-defined
terminology, that can be referenced by the software industry. This document provides guidance on
defining, controlling, and improving software life cycle processes within an organization or a project.
This document recommends methods and approaches suitable for a variety of life cycle models. The
guidance emphasizes the importance of establishing a strategy, planning, and the involvement of
stakeholders, with the ultimate goal of achieving customer satisfaction.
This document applies to the acquisition, supply, design and development, transition, operation,
maintenance, and disposal (whether performed internally or externally to an organization) of software
systems, products, and services (including software as a service (SaaS)), and the software portion of
any system. Software includes the software portion of firmware. The guidance on processes, activities,
and tasks in this document can also be applied during the acquisition of a system that contains software.
The guidance in this document can also be used as a basis for selecting, establishing, and improving
organizational environments, e.g., methods, procedures, techniques, tools, and trained personnel.
In the context of this document, there is a continuum of human-made systems from those that use little
or no software to those in which software is the primary interest. It is rare to encounter a complex
system without software, and all software systems require physical system components (hardware)
to operate, either as part of the software system-of-interest (SoI) or as an enabling system or
infrastructure. Thus, the choice of whether to apply this document for guidance to the software life
cycle processes, or ISO/IEC/IEEE 24748-2, depends on the SoI. At a high level, both documents have the
same life cycle process framework, but differ in guidance for activities and tasks to perform software
engineering or systems engineering, respectively.
