Value Management - Function Analysis: Basic characteristics, requirements and guidance for implementation

This document presents Function Analysis (FA) and specifies requirements for Function Analysis and its deliverables. It presents the two distinct areas of application, namely, Functional Need Analysis (FNA) relating to understanding the need, setting goals and Technical Function Analysis (TFA) relating to selecting and developing a solution. It specifies requirements for the basic characteristics of the deliverables within FNA and TFA and expands requirements, guidance and recommendations about FA expressed in the Functional Performance Specification Standard (EN 16271) and in the Value Management Standard (EN 12973).
This document provides an essential reference and support for any person wishing to improve the efficiency, effectiveness and overall performance of their organization. It aims to support sustainable development in an organization. FA offers an opportunity to enhance skills of people involved.
In order to present the conditions for implementation and development of FA deliverables, this document:
•   introduces the interests and fields of application and presents a variety of situations in which FA is used in support of projects of all types and sizes;
•   specifies essential conditions for successful FA, including roles and responsibilities of the people involved, monitoring the performance of the FA team, processes for validation and verification and supply of valid and verified deliverables; and
•   specifies requirements for FA and the basic characteristics of FA deliverables whilst outlining methods, and tools for the realization of the deliverables.
FA is progressed using the following:
•   FNA: support for the process of identifying and understanding the need, defining objectives, and setting the goal to be achieved;
•   TFA: support for design or research processes and evaluation of solutions; and
•   Iteratively focusing on the FNA and TFA by revisiting the identified need, balancing capabilities of available technologies, resources and constraints, achieving the most desirable outcome.
In the area of FNA, this document sets out FNA requirements for the deliverables to establish the Functional Need Expression (FNE). The FNE can serve as a basis for establishing an understanding of the expressed need, the complete list of User Related Functions (URFs), constraints and interfaces. These deliverables serve as a basis for identifying, organizing, characterizing and prioritizing functions and function interfaces. These deliverables can also support preliminary risk and reliability studies, economic studies, impact assessments and development of Functional Performance Specifications (FPSs).
In the area of TFA, this document sets out requirements for TFA deliverables which aim to satisfy the need, expressed in the FNE. The TFA deliverables are focused on analysing existing and potential solutions, identifying a complete list of the Product Related Functions (PRFs) to meet the FNE; evaluating concepts and making a choice for a solution then optimizing the Product Function Architecture (PFA) to identify the “best” solution.

Value Management - Funktionenanalyse: Grundlegende Merkmale, Anforderungen und Leitlinie für die Umsetzung

Management par la valeur - Analyse Fonctionnelle: caractéristiques fondamentales, exigences et recommandations pour la mise en œuvre

Le présent document présente l’Analyse Fonctionnelle (AF) et spécifie les exigences applicables à l’Analyse Fonctionnelle et à ses livrables. Il présente les deux domaines d’application distincts, à savoir l’Analyse Fonctionnelle du Besoin (AFB), qui permet de comprendre le besoin, de fixer des objectifs, et l’Analyse Fonctionnelle Technique (AFT), qui permet de sélectionner et développer une solution. Il précise les exigences relatives aux caractéristiques fondamentales des livrables dans le cadre de l’AFB et de l’AFT et développe les exigences, les orientations et les recommandations relatives à l’AF exprimées dans la norme sur le cahier des charges fonctionnel (EN 16271) et dans la norme sur le management par la valeur (EN 12973).
Le présent document constitue une référence et un support essentiels pour toute personne désireuse d’améliorer l’efficience, l’efficacité et la performance globale de son organisation. Il vise à soutenir le développement durable dans une organisation. L’AF offre une opportunité pour améliorer les compétences des personnes impliquées.
Pour présenter les conditions de mise en œuvre et de constitution des livrables de l’AF, le présent document :
—   décrit l’intérêt et les domaines d’application, présente différentes situations dans lesquelles l’AF est utilisée en soutien de projets de tous types et de toutes tailles ;
—   précise les conditions essentielles d’une AF réussie, y compris les rôles et les responsabilités des personnes impliquées, la surveillance de l’évolution du GAF, les processus de validation et de vérification pour obtenir la fourniture de produits livrables valides et vérifiés ; et
—   précise les exigences pour l’AF et les caractéristiques de base des livrables de l’AF tout en décrivant les méthodes et les outils pour la réalisation des livrables.
L’AF se met en œuvre en appliquant la démarche suivante :
—   AFB : mise en œuvre du processus d’identification et de compréhension du besoin, de définition des objectifs et de détermination du but à atteindre ;
—   AFT : soutien aux processus de conception ou de recherche et évaluation des solutions ; et
—   la prise en compte itérative entre l’AFB et l’AFT en réexaminant le besoin identifié, en conciliant les capacités des technologies disponibles, les ressources et les contraintes à respecter, afin d’obtenir le résultat le plus souhaitable.
Dans le domaine de l’AFB, le présent document recense les exigences de l’AFB afin d’établir les livrables de l’Expression Fonctionnelle du Besoin (EFB). L’EFB peut servir de base pour établir une description du besoin à satisfaire, la liste complète des Fonctions de Service (FS), des contraintes et des interfaces. Ces livrables servent de base pour l’identification, l’organisation, la caractérisation et la hiérarchisation des fonctions et des interfaces fonctionnelles. Ces livrables peuvent également alimenter des études préliminaires de risque, de fiabilité, des études économiques, des évaluations d’impact ou l’élaboration d’un Cahier des Charges Fonctionnel (CdCF).
Dans le domaine de l’AFT, le présent document recense les exigences pour les livrables de l’AFT qui visent à répondre au besoin exprimé dans l’EFB. Les livrables de l’AFT sont axés sur l’analyse des solutions existantes et potentielles, l’identification d’une liste complète des Fonctions Techniques (FT) pour répondre à l’EFB ; l’évaluation des concepts et le choix d’une solution, puis l’optimisation de l’Architecture Fonctionnelle du Produit (AFP) afin de construire la « meilleure » solution.

Introduction
This document sets out requirements for Function Analysis (FA). FA is used to define and validate
needs, prioritize requirements, assess performance, stimulate innovation, guide design and support
procurement and inform decisions to use, reuse, and recycle parts and products.
FA provides people in different fields of application with a proven method for defining needs,
developing an offer, improving purchases, contracting a partnership or increasing the efficiency of
activities. FA is a process that describes completely the functions and their relationships which are
systematically characterized, classified and evaluated.
0.1 General
The purpose of this document is to provide effective support to any person or organization wishing to
improve its effectiveness or performance or operational activities and in the definition, development or
the realization of any action or project.
FA makes an effective contribution in fields of quality management (EN ISO 9001), environmental
management systems (EN ISO 14001), configuration management (ISO 10007, EN 9223-100),
dependability management (EN 60300-1), circular economy (EN 62309), systems and software
engineering (ISO/IEC/IEEE 15288) and performance management. It is essential for Value Management
(EN 12973) and successful application of a Functional Performance Specification (EN 16271).
FA involves and relies upon a way of thinking, based on a continuous process, with or without a
dedicated team, that encourages the search for the goal and the nee
