Diagramme FASTDiagramme FAST FAST : Function Analysis System Technique Un diagramme FAST présente une traduction rigoureuse de chacune des fonctions de service en fonction(s) technique(s), puis matériellement en solution(s) constructive(s). Input for the diagram is received from workshop participants.There is no 'correct' FAST diagram but there is a valid method of representing the logic in a diagram. The development of a FAST diagram is a creative thought process which supports communication between team members.Three key questions are addressed in a FAST Diagram:The following diagram illustrates how a function is expanded in "How" and "Why" directions in a FAST diagram.Start with the Functions as identified using Function Analysis:Consider the following FAST diagram for a mouse trap using the how and why logic as described above.Can you think of other ways to achieve the basic function of kill mouse or the higher order function to eliminate mice.The Function Analysis System Technique (FAST) diagram is usually prepared in a workshop setting and led by someone with experience in preparing FAST diagrams. There was a problem previewing Document ressource - Diagramme FAST.pdf. Le diagramme FAST se construit de gauche à droite, dans une logique du pourquoi au Retrying.

The FAST diagram aids the team in reaching consensus on their understanding of the projectPromoting the application of Value Methodologies in Canada The FAST diagram can be used to verify if, and illustrate how, a proposed solution achieves the needs of the project, and to identify unnecessary, duplicated or missing functions. The organization of the functions into a function-logic, FAST diagram enables participants to identify of all the required functions. The validity of a FAST model for a given situation is dependent on knowledge and scope of the workshop participants. "Working independently, the resolution of a problem by one discipline becomes the problem of another discipline. Whoops! Sign In. "A technique to develop a graphical representation showing the logical relationships between the functions of a project, product, process or service based on the questions “How” and “Why”.The Function Analysis System Technique aids in thinking about the problem objectively and in identifying the scope of the project by showing the logical relationships between functions.
