Space engineering standards - Functional analysis
This document defines the requirements to perform functional analysis and the information output of that analysis. It applies to all types and combinations of space systems, projects and products. It also applies to project phases 0, A, B and C and at all levels.
When viewed from the perspective of a specific project context, the requirements defined in this document should be tailored to match the genuine requirements of a particular profile and circumstances of a project.
NOTE Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.
Raumfahrttechnik Normen - Funktionenanalyse
Diese Norm legt die Anforderungen zur Durchführung der Funktionenanalyse und hinsichtlich der Ergebnisse dieser Analyse fest. Sie gilt für alle Arten und Kombinationen von Raumfahrtsystemen, projekten und produkten und für die Projektphasen 0, A, B und C auf allen Ebenen.
Die in dieser Norm festgelegten Anforderungen sind programm- oder projektspezifisch anzupassen, d. h. auf das Anforderungsprofil und Betriebsbedingungen des einzelnen Programms bzw. Projekts abzustimmen (tailoring).
ANMERKUNG Tailoring ist ein Prozess, in dem einzelne Anforderungen in Spezifikationen, Normen und ähnlichen Dokumenten nach Bewertung für ein bestimmtes Projekt ausgewählt und in Ausnahmefällen auch modifiziert oder indem neue Anforderungen ergänzt werden.

Foreword This document (EN 14514:2004) has been prepared by CMC. 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of an identical text or by endorsement, at the latest by February 2005, and conflicting national standards shall be withdrawn at the latest by February 2005. It is based on a previous version1) prepared by the ECSS Engineering Standard Working Group, reviewed by the ECSS Technical Panel and approved by the ECSS Steering Board. The European Cooperation for Space Standardization (ECSS) is a cooperative effort of the European Space Agency, National Space Agencies and European industry associations for the purpose of developing and maintaining common standards. This document is one of the series of ECSS Standards intended to be applied together for the management, engineering and product assurance in space projects and applications.
Requirements in this document are defined in terms of what shall be accomplished, rather than in terms of how to organize and perform the necessary work. This allows existing organizational structures and methods to be applied where they are effective, and for the structures and methods to evolve as necessary without rewriting the standards. The formulation of this document takes into account the existing ISO 9000 family of documents. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Tailoring is a process by which individual requirements of specifications, standards and related documents are evaluated and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

NOTE 2 Two kinds of constraints are considered, those which concern solutions, and those which concern the use of the system. NOTE 3 For example constraints can come from environmental and operational conditions, law, standards, market demand, investments and means availability, organization’s policy. NOTE 4 Adapted from EN 1325-1. 3.1.2 function intended effect of a system, subsystem, product or part NOTE 1 Adapted from EN 1325-1. NOTE 2 Functions should have a single definite purpose. Function names should have a declarative structure (e.g. “Validate Telecommands”), and say “what” is to be done rather than “how”. Good naming allows design components with strong cohesion to be easily derived. 3.1.3
functional analysis technique of identifying and describing all functions of a system NOTE Adapted from EN 1325-1. SIST EN 14514:2005
operational mode manner or way of operating NOTE The mode is realized by a group of related functions or tasks required to accomplish a specific operation. 3.1.5 operational scenario summary of sequences of events and the environment for a specific operation 3.1.6 functional specification document by which the customer establishes the intended purpose of a product, its associated constraints and environment, the operational and performances features, and the permissible flexibility NOTE 1 This document contains a complete set of provisional technical requirements for a product.
