Abstract: The purpose of this paper is to illustrate that the procedures described in Part 1 of this paper are equally effective when applied to a complex system. In order to demonstrate this, an automotive braking system was chosen since it involves numerous traditional manufacturing processes. However, some criteria in our extended definition of functionality may not easily apply to this particular case (usability, for instance) since this is an internal mechanical part of a consumer product (car). If the functionality of the internal automotive part can be ensured, it is expected that the overall functionality of the vehicle will also be enhanced.

Keywords: design for functionality; usability; product function; manufacturing checklists; complex systems; product design; product development; automotive braking systems; automobile industry; QFD; quality function deployment.
