NATIONAL FOREWORD
This Indian Standard (Second Revision) which is identical to ISO/IEC/IEEE 15288 : 2023 'Systems and software engineering - System life cycle processes' issued by the International Organization for Standardization and International Electrotechnical Commission Jointly was adopted by the Bureau of Indian Standards on the recommendation of the Software and System Engineering Sectional Committee, and the approval of the Electronics and Information Technology Division Council.
This Standard was first published in 2015 and was identical to ISO/IEC 15288 : 2008. The first revision of this was published in 2020 and was identical with ISO/IEC/IEEE 15288 : 2015.

This editions has been technically revised.The main changes are as follows:
a) Improvements to selected technical processes including business or mission analysis, system architecture definition, system analysis, implementation, integration, operations, and maintenance;
b) Improvements to selected technical management processes including risk management and configuration management;
c) Updates to Clause 5, key concepts, including a better description of iteration, recursion, system-of-systems, quality characteristics, etc.;
d) New content in Clause 5 on concept and system definition, and expanded content on process application and system concepts;
e) Updates to the terms and definitions; and f) A new annex addressing model-based systems engineering (MBSE).
The text of ISO/IEC/IEEE standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appears referring to this standard, they should be read as 'Indian Standard'; and
