GOALS

  • The main purpose of the Product Functional Tree  is to explode complicated tasks into a collection of basic functions. 

SHORT DESCRIPTION

A function is expressed through a verb (which describes an action) and a noun (which specifies the object of the action).
The functions of the product are identified:
  1. starting from the primary functions, which are requested by the users,
  2. adding then the ancillary functions, which are needed to implement the primary ones,
  3. all functions are broken down until it is useful for describing the product.
The definition of the functions should be as neutral as possible from the way the functions will be physically implemented.
The functional view of the product is useful in many phases of the product life cycle: improvement of tests, creation of technical documentation, implementation of modular architecture, product configuration, ...
