        The cost and the best cost for functions are also often marked in a FAST
        diagram. A fully marked function block in a FAST diagram has the format
        indicated by Fig. 7.16. Figure 7.17 gives a portion of the FAST diagram for
        the youth assistance program with fully marked function blocks.

        After the FAST diagram is fully developed and the cost-function work sheet
        is fully filled, we will get into the next stage of the value-engineering job
        plan, the creation stage.

        7.3 Creative Phase

        At the end of the information phase, we have listed all relevant functions for
        the project, filled out the cost-function work sheet, and developed the FAST
        diagram. The difference between the cost and the best cost of each function
        is the profit improvement potential. The functions that have high profit
        improvement potentials are the perfect candidates for cost saving. The
        creative phase of the value-engineering project is to use team members’cre-
        ativity to develop alternative solutions to perform the functions that have
        high profit improvement potentials.  The creative phase is where free
