Functional analysis: methods for finding functions

You're going through every method of function research to ensure the integrity of your work. The various points of view of these approaches systematically guide you towards snippets of technological solutions, while analyzing the product, the functions, the constraints and the environment, responding to the user's need.

This sheet enables you to find all the methods of searching for functions, to recognize their typology, to check their validity and to represent them graphically.

The following methods are available to you:

• informal, spontaneous research (see Functional analysis: expressing needs in terms of functions and methods for finding functions [FIC 0616] );

• research based on needs (see Functional analysis: expressing needs in terms of functions and research methods [FIC 0616] );

• research based on the product's relationship with its environment (see Functional analysis: expressing needs in terms of functions and research methods [FIC 0616] );

• search using function tree decomposition (graphical method) (see The function tree [FIC 0617] file);

• search using the "block diagram" method (graphical method) ;
