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.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at  www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

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

This document was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles,
Subcommittee SC 14, Space systems and operations.
This second edition cancels and replaces the first edition (ISO 21349:2007), which has been technically
revised.
The main changes are as follows:
— updated normative references in Clause 2;
— updated terms and definition in Clause 3;
— deleted numerical syntax of the IDEF0 standard in Clauses 4 and 5;
— deleted information about IEEE Std. 1320.1-1998 in 4.2.1;
— minor changes in 4.3, 5.4.1, 5.4.3, 5.5.1, 5.5.3 and in Annex A;
— added ISO/TS 18667 and ISO 18676 in the Bibliography.

Introduction
Space systems are very complex, incorporating many different technologies. Space programmes can
last for many years, progressing through several different stages from conception to disposal or other
disposition. When a space programme advances from one stage to another, substantial changes in the
type and amount of resources required can occur. In addition, there can be attendant risks to either the
success of the project or to the well-being of project equipment or to personnel. Well-regulated project
reviews can be an important factor in ensuring that all factors are ready for these changes, and that
the risks are well understood and accepted. This document is intended to be used as a basis for the
activities comprising a review, their necessary resources, controls, inputs and results to enhance the
communication between different organizations that participate in a review process and to reduce the
costs of planning and performing reviews.

INTERNATIONAL STANDARD ISO 21349:2023(E)
Space systems — Project reviews
1 Scope
This document specifies process requirements for project reviews as a set of required functions.
It establishes requirements and recommendations on the function inputs, outputs, mechanisms and
controlling conditions.
This document specifies the responsibilities of a review board and gives guidance concerning review
board composition.
This document also provides descriptions of the kinds of reviews that are commonly useful in assuring
the success of a space project.
This document is applicable to status reviews for a project at any level within a larger project, as well
as for major milestone reviews at the top level of a major project. It is intended to be used either by an
independent developer as a basis for enterprise processes, or as a basis for an agreement between a
supplier and a customer. It is intended for use in implementing the review requirements of ISO 14300-1,
and ISO 14300-2, ISO 15865 and such other space systems and operations standards that require formal
reviews.
