Description of BS EN 17952:2024 2024

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.
