Functional Analysis and Allocation Practice
6. 
Control mechanisms
—the enforcement of business or control rules to 
decide which conditional branch is to be executed. Loops provide a control 
mechanism that causes a segment of the functional sequence to be reexecuted 
one or more times. (
Note:
 A loop may be continuous (neverending) or termi-
nated based on the achievement of a conditional criteria (e.g., 
Do
…
Until
)) 
(see task 11.2.4).
7. 
Computing resources
—the consumable or reusable assets provided by the com-
puting environment, such as memory, data storage, and communication interface 
bandwidth (see task 11.2.6).
