The condition workflow item splits a workflow in two. Learners take different paths depending on whether a variable does or doesn't meet a set of criteria specified in the condition.
Configuring it
First, decide what you need to know. Do you want learners to receive different outcomes based on how they performed in a test, what their email address is, where they're located? You need to make sure the information you're questioning is available in a Variable. The variable you select will form the basis of your criteria.
Then you need to select an Operator, this dictates how the condition will evaluate the variable.
And finally you need to enter a Value that the operator will use to evaluate your variable. For example:
This workflow gets the learner's completion information for the staff handbook, then the condition asks whether that completion is "true". If it is "true", the learner follows the green true route beneath the condition. If not, they follow the red false route.
