European foreword
This document (EN 9277:2015) has been prepared by the Aerospace and Defence Industries
Association of Europe - Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this Standard has
received the approval of the National Associations and the Official Services of the member countries of
ASD, prior to its presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by March 2016, and conflicting national standards shall
be withdrawn at the latest by March 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such
patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.

Introduction
This document aims to address the current challenges of the programmes that are:
 the multi projects approach,
 the multi-disciplinary approach,
 new methods of acquisition,
 the increasing complexity of systems to be acquired,
 the evolving aspects of the system and its incremental development,
 the complexity of the management of projects in terms of organization,
 the evolution of the industrial sectors.
In this document the system considered comprises a target system and elements (products, processes,
etc.) needed for developing, producing and using it, in other words a range of end products and
products supporting the lifecycle of the target system.
The case where the system is only an element of the service provided (no system is acquired, service
only) is not adressed in this document.
Systems Engineering (SE) cover a set of activities which, based on a perceived operational need and
via an organized approach, aims to:
 describe this need in technical terms,
 gradually transform it into a system solution,
 at each stage, demonstrate that this system is compliant with the need.
Systems Engineering:
 considers the system as a whole and in all situations of its lifecycle,
 provides a framework for combining various technical disciplines (electronics, data processing,
mechanics, ergonomics, etc.) and some enterprise functions (design, production, logistics, tests,
etc.) without necessarily intervening in these disciplines and functions,
 aims for the overall optimization of the solution in a field of constraints (costs, schedule,
performance, strategy, etc.) established by the Programme management,
 guarantees consistency between all components of the solution (functional and physical
interfaces).
In this document, the organisational dimension is essential to reach the overall objectives. The
complexity of the system and the complexity of the organisation are correlate (the more complex the
system is, the more control of the organisation is necessary).
Its position with respect to other normative documents handling Systems Engineering (ISO/IEC
15288, EIA 632,IEEE 1220, EN 9200) is represented in Annex A. This document falls within the scope
of EN 9200 and ISO/IEC 15288, focusing on aspects linked to the management of the technical
activities of SE with a higher level of detail. It relies partly on the SE process described in ISO/IEC
15288:2008 and if necessary with addition from EIA 632, adding the project phasing and scheduling
aspect. It overlaps little with IEEE 1220 as such, which concentrates primarily on SE technical
activities.
1 Scope
Based on the following considerations:
 reminder of Systems Engineering and its scope of application,
 positioning of SE management in Programme Management and in relation to Systems Engineering
technical activities,
 identification of interfaces between SE management and the other disciplines linked to
Programme Management,
the purpose of this standard is:
 to help the acquirer and the Organization to establish management requirements for SE activities,
 to help the supplier to construct the elements of the management plan (explain how to reply in
particular to the management requirements).
This standard applies to the various levels of the product tree for the products that can be considered
as systems:
 in the general case of an supplier which, with the help of one or more suppliers, develops a system
on behalf of an acquirer,
 in the case of an integrated team (sharing of SE roles, responsibilities and risks).
NOTE ISO/IEC/IEEE 24765:2010 integrated team should include organisation discipline and functions which
have a stake in the success of the work products.
This standard constitutes a guide illustrating the requirements and possible responses for SE
management. It can be used as a check-list which should be adapted or completed according to the
specific context of each project.
