Transition TransitionA transition is a true-false test, evaluated during activity execution, that determines whether the flow of control in an activity continues with the next numbered step.
A transition is a reference to a when condition (Rule-Obj-When rule type) or an expression that evaluates to True or False. After the method referenced in an activity step executes, but before processing continues with the next numbered step, the system evaluates the when condition or expression. The resulting value (True or False) can cause the activity execution to continue, end, or continue at a higher-numbered step.
On the activity form Steps tab,
the 
icon identifies
the transition column. When a row is not selected, a 
indicates that this step has a transition defined.
When the row is activated, click 
to add a transition or the 
to access the details of the transition.
When a
method in an activity step affects the value of a property
computed by a Declare Expression rule, the declarative rule
execution occurs before the system evaluates the
transition. For example, if the method updates the value of a
Diameter property, and a Declare Expression rule computes a
CircleArea property from Diameter, only the updated CircleArea
value is available to the transition.
The transition phase is the final phase in the Pegasystems Implementation Methodology, during which the application is placed into production use with the appropriate IT infrastructure.
