• At execution time, only one of several possible alternatives can be processed in the workflow from a business point of view, and then the comparison is to be performed again.
• The workflow system can make a decision based on the contents of the workflow container.
• The decision can be formulated based on a comparison between an expression from workflow container and a finite amount of comparison values (constants, expressions).

In the workflow definition a WHILE loop is represented with the symbol .

At runtime, the workflow system compares the value of an expression of the workflow container with the defined comparison values. If the system cannot establish any agreement, the workflow is continued in the Other values branch.

If the value of the expression of the workflow container agrees with one of the comparison values, the steps modeled in the relevant branch are processed. Then the return jump occurs and the system runs the loop check again.

Assign a step name and define the basis of comparison as an expression of the workflow container. Enter a name for each comparison value. These names identify the various processing branches in the workflow definition.

The branch Other values is created automatically by the system even if you do not assign a name. This ensures that the workflow definition is executable.
