Standard Practice for Constructing FAST Diagrams and Performing Function Analysis During Value Analysis Study
SCOPE
1.1 This practice covers a logical structure for the function analysis of a building project or process.
1.2 This practice provides a system to identify unnecessary costs of a project.
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
