Fast Secondary Functions

It is the authors' intent that the Function Analysis Guide will result in a greater understanding of function analysis and FAST diagraming to the extent that it becomes second nature to those using the VM to improve their projects, products and processes. Application of the techniques covered herein will result in better studies and, most

The organization of the functions into a function-logic diagram, such as a FAST diagram enables participants to identify of all the required functions. 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.

A function that is necessary in a project, product, or process to perform the basic function. Required secondary functions fall on the Critical Function Logic Path within a FAST diagram. Unwanted Secondary Function. A negative secondary function caused by the method used to achieve the basic function, e.g., heat generated from lighting, which

between basic and secondary functions and their subsets is also incorporated into the FAST process. The most dramatic differences are in the use of intuitive logic to quottestquot the functions and to graphically display them in a diagram or model form. Function analysis is a common language, crossing all technologies. It allows multi-disciplined

FAST is a technique that is used to develop a representation graphically, where the relationships between functions in a product, process, or service can be displayed. From here, you then prioritize them. Identify which ones are the primary functions, the basic functions, the secondary ones, and so on. 2. quotHowquot and quotwhyquot

3. Identifies Value-Adding and Non-Value-Adding Functions. FAST diagrams distinguish between basic functions that are essential to the system and secondary functions that may be redundant or non-value-adding. This visibility into value and non-value activities is crucial for eliminating waste and focusing efforts. 4.

The basic function is the overall product function. For example, the basic function of a car seat belt is to restrain a person in a car seat. The Secondary functions- these are essential to the performance of the basic function and they are direct cause to the basic function. Secondary functions can be categorized into 3 types Required Aesthetic

This document provides information about function analysis system technique FAST. It discusses that FAST was developed in 1964 by Charles Bytheway as a function-oriented rather than time-oriented method to effectively communicate and resolve multi-disciplinary issues. FAST uses verb-noun functions to describe complex systems through visual tree diagrams that show the basic function and

FAST, whose initials stand for Function Analysis System Technique, is a structured approach used in product and system design. This concept focuses on identifying and organizing the essential functions. Identify the main functions removing stains, the secondary functions softening the laundry and the constrained functions not damaging
