EN 16601-00:2018 (E) 4 European Foreword This document (EN 16601-00:2018) has been prepared by Technical Committee CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN (Germany). This document (EN 16601-00:2018) originates from ECSS-S-ST-00C. This standard covers the subject of Tailoring of Space standards and therefore replaces EN 14724:2003 "Space project management – Tailoring of space standards". In addition this standard contains the top level requirements formerly covered in EN 13290-1:1999; EN 13291-1:1999 and EN 13292:1999, while the while the remaining requirements were moved to EN 16601-10:2015, (replaced by EN 16602-10-2017 and replaced by EN 16603-10:2018. This document has been developed to cover specifically space systems and will therefore have precedence over any EN covering the same scope but with a wider do-main of applicability (e.g.: aerospace). This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association.

EN 16601-00:2018 (E) 5 1 Scope This document is the top–level document of the EN 16000 Series of European Space Standards. It gives a general introduction into European Space Standards and their use in space programmes and projects.
Its purpose is to provide users with an overview of the European Space Standards System (that is based on the ECSS System), together with an introduction to the various branches of applicability and to the disciplines covered by these set of Standards and the processes involved in generating and using these standards. As an introduction into space programmes, space projects actors and their customer-supplier relationships are described.
The branches are: • EN 16001 Series: Space system and Space project management • EN 16002 Series: Space product assurance • EN 16003 Series: Space engineering • EN 16004 Series: Space sustainability Application of the ECSS System for space projects in the customer-supplier chain is explained and a practical tailoring method is described together with methods for collecting and processing user feedback. Finally top-level requirements are defined for implementation of the ECSS system in space projects/programmes. This standard is applicable to all the procurements of space products. With effect from the date of approval, this Standard announces the adoption of the external document on a restricted basis for use in the European Cooperation for Space Standardization (ECSS) system. This standard may be tailored for the specific characteristic and constraints of a space project in conformance with clause 7 of this standard. SIST EN 16601-00:2019

EN 16601-00:2018 (E) 8 4 Objectives and policy The overall objectives of using the European Space Standards system include: • achieving more cost effective space programmes and projects in Europe, • improving the competitiveness of European space industry, • improving the quality and safety of space projects and products,
• facilitating clear and unambiguous communication between all parties involved, in a form suitable for reference or quotation in legally binding documents, • reducing risk and guarantee interoperability and interface compatibility by applying proved and recognized requirements and methods. In order to meet the above stated objectives, the following policy principles are applied: European Space Standards are produced to support the formal customer-supplier relation in developing space programs and projects. In order to ensure European space programmes and projects’ efficiency in terms of technical performance, life cycle cost-effectiveness and on-time deliveries, the European Space Standards System can be adapted to specific domains of application by use of tailoring activities. NOTE
See Annex A "Example of template for an EARM for the requirements". Systematic feedback of experience from programmes, projects and other appropriate sources allows improvement of the Standards. SIST EN 16601-00:2019



EN 16601-00:2018 (E) 9 5 European Space Standards System description 5.1 Overview The European Space Standards System has been developed as a cooperative effort between the European space agencies and space industries. It comprises a comprehensive set of documents addressing all essential aspects of the major branches for the successful implementation of space programmes and projects, namely • Space system and Space project management, • Space engineering,
• Space product assurance, and
• Space systainability. All user oriented documents fall in one of those branches.
5.2 Space standards Space standards are documents for direct use in invitation to tender and business agreements for implementing space related activities.
They state verifiable requirements, supported by the minimum descriptive text necessary to understand their context.
Each requirement contained within a Standard has a unique identification, allowing full traceability and easy verification of compliance. When a requirement asks for the delivery of a document, the scope and content is specified in a dedicated DRD (Document Requirements Definition), which forms an integral part of a standard.
The Space standards focus primarily on what is required to comply with each standard, rather than how to achieve this. This approach provides the flexibility for different customers and suppliers to use established “in–house” procedures, or processes, to comply with these standards.

EN 16601-00:2018 (E) 11 5.3.2 Space system and Space project management (EN 16601-branch) The overall objective of space system and space project management is to implement a process to achieve successful completion of the project in terms of cost, schedule and technical performance. Project management is performed following a structured approach throughout all stages of its life cycle and at all levels of the customer-supplier chain. It integrates all management, engineering and product assurance functions required to execute the project. Table 5-1 presents an overview of the disciplines covered by European Space Standards management branch (EN 16601). It is not intended to be exhaustive. Table 5-1: Disciplines in the space system and space management branch Discipline Title Scope / Objective 16601-00 Space system Integrate the complete set of European Space Standards. 16601-10 Project planning and Implementation Project planning and implementation discipline provides a coherent set of processes for minimizing the technical, scheduling and economic risks of the project. In particular this is done by:
• introducing phases and formal milestones enabling the progress of the project to be controlled with respect to cost, schedule and technical objectives. • defining project breakdown structures, which constitutes the common and unique reference system for the project management to: • identify the tasks and responsibilities of each actor; • ensure the coherence between technical, documentary, administrative and financial activities of the whole project; • perform scheduling and costing activities. • setting up a project organization to implement a structured and complete approach to perform all necessary activities on the project. 16601-40 Configuration and Information Management Configuration management and information discipline: • identifies, describes and controls the technical description of a system in a logical and consistent manner throughout the system’s life cycle, and • ensures that the information necessary for effective execution of all management processes are recorded, retrieved, distributed and modified in a traceable manner.

In particular it includes: • The systematic identification, assessment and classification of all risk causes and consequences prior to definition and implementation of a decision to accept, to monitor or to take action. The risk assessment supports the decision making process, including consideration of uncertainties about the risk involved. Independent verification of the risk assessment ensures its objectiveness. • The systematic definition, implementation, control and verification of actions appropriate for elimination or reduction of risk to an acceptable level. 5.3.3 Space engineering (16603-branch) This discipline covers the engineering aspects of space systems and products, including: • the engineering process as applied to space systems and their elements or functions, and • technical aspects of products used to accomplish, or associated with, space missions.
