Mistakes to avoid
"Re-engineering a product with functional analysis: preliminary work and stages of this tool

Criticize the product to be "redesigned": the aim is to create, not to criticize. It is therefore advisable to:

• analyze the product without judgment to extract all its functions and constraints;

• to ask the question, being a "new being" (ignorant): How do I achieve this function?

• to list all existing possibilities without judgement;

• prioritize solutions;

• to choose the right solution.

Work without limits: set limits to your study by clearly explaining that module X, providing such and such a function, will not be studied, for reasons of time, or the functional analysis (FA) has already been done, for example.
