Function Analysis System Technique (FAST)

Developed by Charles W. Bytheway, FAST is a diagramming tool applying structured precedent logic to model a project, product, or process. The diagram helps to identify and analyze functions to stimulate creativity and
innovative thinking. It is a visual aide for the team as they brainstorm or explore alternatives to evaluate and analyze functions. The logic technique forces the brain to think differently resulting in changing the viewpoint and broadening how one views a project, product, or process.
