"Systems and software engineering - System life cycle processes" is the basic standard of system engineering. It sets the concept of the system and life cycle itself, distinguishes between the system of interest and the enabling system, introduces the concept of life cycle practices.
Its latest version was adopted in May 2015, before this version, the version of 2008 was used.
In the new version of the standard, a list of practices (different version in comparison with the Russian official version) is formulated, which should be performed by system engineers and managers at all stages of the system's life. And here we talk not only about specific technical practices, but also about practices such as contractual relations, management of project and portfolios, risk management, human resources management.
Compared with the previous (or the one translated into Russian before) version of this standard, among the list of technical practices there appeared practices of business analysis, identification of needs and requirements of stakeholders, knowledge management and others.
