A decision is a point in a process to select the path the business process must follow. The selected path depends on the evaluation of one or more conditions (decision rules).
By default, a Decision node includes:
One Condition: Condition on which the rule is evaluated.
True Path: The path of execution when the decision evaluates to true.
False Path: The path of execution when the decision evaluates to false.
At runtime, the value of the decision variable is passed as an operand/keyword into the process map and may be evaluated against another variable or value.
For example, in the Loan Approval map, the Send Confirmation Letter and Send Rejection Letter are two possible paths for the Approved decision. If the APPROVED condition evaluates to TRUE, the Send Confirmation Letter activity takes place at which point the confirmation letter is sent to the customer, and the money is transferred to the customer's credit account. Otherwise, the Send Rejection Letter activity takes place, at which point the rejection letter is sent to the customer.
