Draw IDEF0 diagrams to define the process of preparing a cheeseburger. The basic steps should include: Make hamburger patty Light grill Place patty on grill Flip burger Check for desired "done-ness' (continue checking until well enough done) Melt cheese on burger Select condiments (ketchup, mustard, relish, pickles, mayo, etc.) Toast bun Stack burger and selected condiments on bun It is not necessary to decompose the nine basic process steps listed above into more detail. However, be sure to include all relevant information (inputs, outputs, constraints/controls, and resources/mechanisms). Note that you will need at least three diagrams.
