Line 30:

* ''Flow connection'': Lines connecting functions should only indicate function flow and not a lapse in time or intermediate activity.

* ''Flow direction'': Diagrams should be laid out so that the flow direction is generally from left to right. Arrows are often used to indicate functional flows.

* ''Summing gatesgate'': A circle is used to denote a summing gate and is used when AND/OR is present. AND is used to indicate parallel functions and all conditions must be satisfied to proceed. OR is used to indicate that alternative paths can be satisfied to proceed.

* ''GO and NO-GO pathspath'': “G” and “bar G” are used to denote “go” and “no-go” conditions. These symbols are placed adjacent to lines leaving a particular function to indicate alternative paths.
