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).
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).

This edition cancels and replaces the first edition (ISO 14621-1:2003), which has been technically
revised. The main changes compared to the previous edition are as follows:
— Introduction and definitions have been revised,
— consistency has been checked with ISO 14621-2, and

Introduction
ISO 14621-1 and ISO 14621-2 are designed to jointly assist the user and supplier communities in
developing and executing an effective process for the design, selection and application of electrical,
electronic, and electromechanical (EEE) space parts throughout the life cycle of the programme.
NOTE In both ISO 14621-1 and ISO 14621-2, the family of EEE parts includes electro-optical parts.
The strategy represented in the ISO 14621 series is:
— for ISO 14621-1 a system approach to managing risk throughout the life cycle of the programme, by
developing, selecting and properly applying the right EEE part for its intended application;
— for ISO 14621-2 a framework for developing and documenting an EEE parts control programme
to assure that the parts used in space flight hardware have acceptable risk, i.e. possess adequate
functional, radiation and reliability characteristics to meet the system requirements.
Both ISO 14621-1 and ISO 14621-2 should be tailored to meet the specific needs of each individual
programme, i.e. to address the applicable system performance requirements, risk tolerance, budget,
mission duration, operating environment, and schedule. Tailoring should result in a set of planned
activities that are not only capable of achieving all contractual EEE parts related requirements, but
also commensurate with the space system’s unit-value/mission-criticality and life cycle technical data
product requirements.
NOTE This type of planning is sometimes referred to as capability-based Safety, Dependability, and Quality
Assurance (SD&QA) programme tailoring; and the guidance for performing it is provided in ISO/TS 18667.
ISO 14621-1 and ISO 14621-2 are relevant to all users and customers of space systems, and the suppliers
and vendors that furnish space flight hardware. However, to utilize these documents to their fullest
potential, it is necessary to understand the commercial space business environment which has unique
cost and schedule constraint challenges.
This document discusses the following key elements that support an effective EEE parts management
programme:
— Part obsolescence management — perform early assessment of part availability risk for the entire
space system, develop and implement risk mitigation activities that will prevent or minimize
programme disruption due to part shortages, and ensure long-term supportability throughout the
programme life cycle.
— Supplier management — plan and execute techniques for verifying that the practices and products
of suppliers and vendors comply with:
— contractual requirements;
— their documented internal business practices (also known as command media), which should
be consistent with the commercial consensus on technical best practices.
— Cost management — minimize the costs, including verifying parts suppliers and vendors can provide
the rationale why they set different costs for parts that are functionally identical, e.g. identify the
cost of special processing applied to parts that are designed for a specific space environment or
mission.
— Technology insertion — focus on creating a technology road map, which minimizes risk of
obsolescence and develops a strategy for technology insertion during the entire system life cycle.
— Space parts community alert exchange — have a forum focused on managing peer to peer
communication among space industry participants seeking to reduce or eliminate expenditures of
resources on common problems, by sharing EEE parts related problem information collected during
research, design, development, production, and operational phases of the programme.
— Process control — ensure the user’s and supplier’s approaches for controlling EEE parts risks, and
risks of other critical items and processes, are documented, formally approved, and validated.
— Systems engineering — encourage parts engineering participation in all phases of the product
life cycle.
— Training — provide effectively trained resources on the various processes required to develop,
select, and properly apply the right EEE part for the its intended application, as well as to establish
awareness of the parts management programme throughout all levels of the user and supplier
communities.
Those specific elements or opportunities are presented in descriptive terms and illustrated in graphic
flow charts. There is no intent to provide detailed descriptions of “how to” in this document. It may be
cited as a basic guideline within a statement of work and/or for assessing proposals and contractor
performance. All levels of contractual relationships (acquiring activities, primes, subcontractors and
suppliers) may use this document. It is the responsibility of the user community to establish, define,
and administer those tasks based on the programme goals and objectives and thus provide the “what”
elements envisioned and establish their appropriate criteria for their programme.
Although this document was written with the intent of covering EEE parts, the concept established
is a system approach for developing an EEE parts programme with reference to specific material and
mechanical processes that make up EEE parts.
