After participating in a function analysis, even experienced team members who have worked on the same project for years may discover a new understanding of the project for which they are responsible. The wonderful aspect of this “new” understanding is that it is a common understanding among all team members. When a team works together to develop a random function list and a FAST diagram, it creates something as a team. Thus, no matter the technical background of the participants, each person can describe the product in functional terms. The use of generic, non-technical functional terms creates a level playing field. In addition, because the entire team participated in creating the function logic diagram, there is buy-in or agreement from all
team members regarding what the project under study performs.
