Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives or www .iec .ch/ members
_experts/ refdocs).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/
or on the ISO list of patent declarations received (see www .iso .org/ patents) or the IEClist of patent
declarations received (see http:// patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/
iso/ foreword .html. In the IEC, see www .iec .ch/ understanding -standards.
This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 7, Software and systems engineering.
This document cancels and replaces ISO/IEC 15504-5:2012, which has been technically revised.
The main changes compared to ISO/IEC 15504-5:2012 are as follows:
— all processes and their base practices are changed to reflect the ISO/IEC/IEEE 12207 processes;
— all process related process outputs and their descriptions are revised;
— this process assessment model includes a process quality attribute of process performance and can
be used with other models of process quality, for instance capability as described in ISO/IEC 33020.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html and www .iec .ch/ national
-committees.

Introduction
The set of International Standards ISO/IEC 33001 to ISO/IEC 33099, termed the ISO/IEC 330xx family,
defines the requirements and resources needed for process assessment. The overall architecture
and content of the ISO/IEC 330xx family is described in ISO/IEC 33001. Several standards in the
ISO/IEC 330xx family for process assessment are intended to replace and extend parts of the
ISO/IEC 15504 series. Abstracts and previews of the ISO/IEC 330xx family of standards can be found on
the ISO website.
This document defines a process assessment model for software life cycle processes, conforman
