Description

A Pool represents a participant in a collaboration. The participant can be a specific partner entity, for example, a company, or it can be a more general partner role, such as a buyer, seller, or manufacturer. Graphically, a Pool is a container to partition a process from the other pools.

A Pool can contain a process, or it can be a black box.

A Pool with suppressed content will display a multi-instance marker if the participant referenced by the pool has a minimum multiplicity value of two or more.

A Lane is a sub-partition within a pool. Lanes are used to organize and categorize activities within a pool according to function or role. They are as follows:

• internal roles, for example, Manager and Associate
• systems, for example, an enterprise application
• internal departments, for example, shipping or finance

In addition, Lanes can be nested in a pool. For example, there could be an outer set of Lanes for company departments and an inner set of Lanes for the roles within each department.
