Validate functions
Functional analysis: represent the tree structure of functions to find appropriate technical solutions

Whichever method you choose, you and your workgroup must schedule a meeting to validate the functions.

Check :

• logical sequence of decompositions ;

• vocabulary: are verbs and complements appropriate?

• the level of detail of certain functions: detailed development means extra time spent finding solutions, and therefore longer lead times;

• graphic representation :

  • hierarchy of functions (top to bottom = most important to least important),

  • link between functions = respect the representation of operations to be performed simultaneously ( and ) or alternatively ( or ).

Ask yourself the following...
