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 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).
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

Introduction
The manufacturing readiness review (MRR) is a formal examination to determine if the design (of product
definition and requirements, manufacturing documentation, processes, personnel, materials and parts,
facilities, etc.) is ready for production. The supplier performs MRR, prior to starting the manufacture of
the product, to review the consistency between manufacturing conditions and manufacturing baseline,
to ensure on time delivery of the product with quality and quantity guaranteed, and to help identify and
mitigate the risks in the manufacturing procedure.
This document provides general requirements for organizing and performing the MRR for deliverable space
products, which include initiation process of MRR, content of MRR, implementation for MRR, and activities
after MRR.
This document provides a common set of requirements for MRR to encourage international space cooperation
for quality control and to optimize the costs of planning and performing MRR reviews.

3.1.1
manufacturing readiness review
MRR
production readiness review
formal examination to determine if the design (of product definition and requirements, manufacturing
documentation, processes, personnel, materials and parts, facilities, etc.) is ready for production
Note 1 to entry: The typical programme milestone (phase ending) is a detailed design stage during or at the end of the
development phase. The typical milestone criterion is the completion of the production plan.
3.1.2
manufacturing baseline
series of confirmed documents used to describe and specify the manufacturing status of deliverable space
products, including relevant requirements of personnel, equipment and facilities, environment, material,
method, measurement in manufacturing process
Note 1 to entry: The manufacturing baseline mainly includes design documents, drawings, process documents and
product assurance documents, etc.

4 Management requirements for MRR
4.1 Purpose of MRR
The purpose of MRR is
a) to determine if the design of product definition and requirements, manufacturing documentation,
processes, personnel, materials and parts, facilities, etc., is ready for production, and
b) to ensure that execution of manufacturing meets the requirements of customer and project.
4.2 General organization of MRR
The general requirements related to the reviews organization as defined in ISO 14300-1 and ISO 21349
shall apply.
The supplier shall perform the MRR, prior to starting the manufacture of deliverable space products, to
review the consistency between manufacturing conditions and manufacturing baseline, to ensure on time
delivery of the pro
