About This Item
ASTM E2013 is the ASTM standard focused on developing functions, constructing FAST diagrams, and performing function analysis during Value Engineering (VE) and Value Analysis (VA) studies. It provides a structured way to describe what a system, product, or process is intended to do and how those functions relate to one another. That makes it useful for teams that want a clearer basis for evaluating alternatives, improving value, and supporting consistent decision-making during technical review.
What is ASTM E2013?
ASTM E2013, titled Standard Practice for Developing Functions, Constructing FAST Diagrams, and Performing Function Analysis During Value Engineering (VE)/Value Analysis (VA) Study, is a practice for organizing functional thinking in a formal study setting. It is centered on defining functions, mapping them with FAST diagrams, and analyzing how those functions support the overall objective. In practical use, the standard helps teams apply a repeatable method for understanding performance needs and comparing options in a disciplined way.
Where is ASTM E2013 used?
This standard is commonly used in VE and VA workshops, design reviews, and other structured evaluation efforts where a product, system, or process must be examined by function. It is relevant when teams need to clarify required functions, identify unnecessary complexity, or compare alternatives before making decisions. ASTM E2013 is especially useful in project planning, engineering analysis, and procurement-related reviews where a function-based approach can improve communication and support better value outcomes.
Why is ASTM E2013 important?
ASTM E2013 matters because it gives teams a common method for analyzing function, which can improve consistency and reduce ambiguity during value studies. By using a recognized ASTM practice, organizations can support more reliable review processes, better documentation, and clearer communication among stakeholders. It may also help reduce risk by making functional requirements more visible before design or procurement decisions are finalized. For many users, ASTM E2013 serves as a practical reference for disciplined value analysis.
