What Is FAST and What Makes It Unique?
Function Analysis System Technique (FAST). FAST is a unique, disciplined way of thinking, a methodology used to identify, depict, and analyze functions and function relationships with the objective of improving their interaction to more efficiently achieve the end objective. Function is the end result desired by the customer; it is what they buy. It is the requirement, the goal, and the objective, it is not an action, it is the result of an action.
The identification and analysis of functions represents the foundation upon which VE is based and separates it from the variety of process and product improvement initiatives throughout the Government and industry.
FAST was developed by Mr. Charles W. Bytheway in 1964 and first presented and published as a paper at the 1965 International Conference of the Society of American Value Engineers.
While the methodology of FAST is deceivingly simple, the application is difficult. It is so simple to understand that it is frequently mistaken for common sense. The application of FAST requires a change in thinking habits, making it necessary to apply strict discipline to encourage innovation and keep from reverting to the same old way of thinking.
