We designed the Burger Truck System by showing its DFD in Chapter 5. Recall that we started with the activity analysis, the context diagram, and the decomposition of Process 2. Please follow our design in the class and complete the decomposition for Process 1 Take Order, and Process 3 Procure Materials (Please use Gane and Sarson symbols in your DFD).
