Functional Block Diagram: Define a top-level functional block diagram. Guidelines for the top-level functional diagram are:

• There should be about 3 to 6 functions at this level (with some exceptions possible).
• The functional block diagram should show all the inputs and outputs of the system going to and from at least one of the functions (or to the whole system if applicable).
• There should be internal interfaces between at least some (if not all) of the functions inside the system; and these interfaces should be labeled uniquely (different names) from the system inputs and outputs.
• Functions should be labeled using verbs.
• Every function should have at least one input and one output.
