                from right to left, the question is WHY. On the vertical axes, WHEN questions have
                to be addressed to complete the fast diagram. A FAST diagram of a bakery is pre-
                pared and presented in Figure 10.12. The scope is to make quality pastries.
                  Brainstorming sessions based on function analysis are foreseen for the VIPs pro-
                cess simplification and value engineering. The alternatives created are evaluated
                based on cost, and added-value analysis.
