TS EN 1325-2

TS EN 1325-2 is a vocabulary standard concerned with the terms and definitions used in value management, value analysis, and functional analysis. In general technical practice, value management is a structured approach to improving the relationship between functions, performance, cost, and purpose in a product, service, process, or organisation. The title indicates that this document is about shared terminology and conceptual clarity rather than introducing a new engineering method.

How value management, value analysis, and functional analysis fit together

In broader professional use, value management focuses on clarifying objectives, identifying required functions, and supporting decisions that deliver the needed function with appropriate resource use. Value analysis examines whether a proposed or existing solution provides its functions efficiently relative to cost and other constraints. Functional analysis looks at what a system does, separating required functions from the physical means used to achieve them. That distinction matters because different teams can use the same words in different ways unless the terminology is standardised.

Why this kind of vocabulary standard matters

• Internal improvement and cost-optimisation work
• Shared terminology across design, procurement, project, and process teams
• Function-focused evaluation in research and development
• Clearer technical documentation, training material, and contractual language

This listing refers to a withdrawn standard, but the subject remains relevant wherever value-oriented decision making is used. Vocabulary standards are especially useful because they reduce ambiguity before methods, workshops, or analyses begin. In complex projects, if value, function, cost, and performance are not defined consistently, teams may reach conclusions that are difficult to compare or defend.
