TS EN 1325-1

TS EN 1325-1 is a vocabulary standard that gathers terms and definitions used in value management, specifically for value analysis and functional analysis. In practical engineering, organisational, and service contexts, it supports a common language for discussing what a product, process, or service is supposed to do, and how those functions are described. This document is about terminology, not about prescribing the full value engineering method itself.

How value analysis and functional analysis fit together

In general technical use, value analysis examines the relationship between cost and the functions a solution delivers, with the aim of reducing unnecessary complexity while preserving required performance. Functional analysis helps identify and structure those functions by distinguishing primary and supporting roles and by showing how functions relate to one another. The terms covered by this standard help teams use those concepts consistently across design, management, and improvement work.

Why a controlled vocabulary matters

• Reduces ambiguity when different departments discuss the same function or requirement.
• Supports value studies, design reviews, and improvement workshops.
• Helps keep cost, performance, and function discussions methodical.
• Improves consistency in translation and multilingual technical documentation.

The Part 1 designation indicates that this is the first part of a broader vocabulary series. Based on the supplied scope, this listing confirms only that it defines terms related to value analysis and functional analysis; it does not, by itself, establish detailed clause content, classifications, or specific procedural requirements.
