Using IDEF₀, develop a functional model to specify "Hot Box Pizza", whose functionality and system boundary have been clearly specified by its A₀ function model as presented in class.

Your model should specify both the physical and information processes in the organization down to its 2nd level of decomposition (i.e., include function blocks at the Axx level), taking into consideration of:

1. Four types of customers - phone order, on-line order, "buying-slice" order, and dinning-in order

2. The financial processes involved such as: revenue from customers payments, payments to materials, payments to wages and taxes, profits

You should provide a textual description of the overall system/organization of concern, as well as for each of the function blocks presented in the model.
