10.8 Lanes

A Lane is a sub-partition within a Process (often within a Pool) and will extend the entire length of the Process level, either vertically (see Figure 10.122) or horizontally (see Figure 10.123). Text associated with the Lane (e.g., its name and/or that of any Process element attribute) can be placed inside the shape, in any direction or location, depending on the preference of the modeler or modeling tool vendor. Our examples place the name as a banner on the left side (for horizontal Pools) or at the top (for vertical Pools) on the other side of the line that separates the Pool name, however, this is not a requirement.

A Lane is a square-cornered rectangle that MUST be drawn with a solid single line (see Figure 10.123 and Figure 10.124).

The label for the Lane MAY be placed in any location and direction within the Lane, but MUST NOT be separated from the contents of the Lane by a single line (except in the case that there are sub-Lanes within the Lane).
