TS EN 1325

TS EN 1325 is a vocabulary standard for Value Management, bringing together terms and definitions used in this field. Its focus is to align the language used around Value Management (VM), Value Analysis (VA) and Function Analysis (FA), so that optimisation-oriented work is discussed with consistent meanings.

Why Value Management terminology matters

Value Management is a structured approach used to assess functions in relation to cost, performance and efficiency. In practice, terms such as function, alternative solution and value are closely linked; if they are used inconsistently, teams can misinterpret discussions and produce uneven documentation. As a vocabulary standard, this document aims to provide a common technical language for both specialists and non-specialists.

Conceptual coverage of the standard

• Defines key terms in the fields of Value Management, Value Analysis and Function Analysis.
• Clarifies terminology for important methods and tools used in the discipline.
• Aims to establish a common and accessible language for international communication.
• Helps distinguish specialised meanings from everyday usage where the same word may imply something different.
• Supports consistency and reduces the risk of terminology mismatch across internationally applied standards.

In general technical terms, a vocabulary standard does not prescribe a step-by-step method; instead, it stabilises the meanings of the concepts used by a discipline. For that reason, TS EN 1325 is useful as a reference for documentation, training, communication and coordination in multidisciplinary value-oriented work.

This edition is based on EN 1325:2014 and is presented by TSE as an active standard. It is particularly relevant for organisations, consultants, project teams and training environments that need a shared terminology for Value Management.
