UsageJourney
An ordered sequence of UsageJourneySteps describing one end-to-end interaction a user has with the digital service.
Params
name
A human readable description of the object.
uj_steps
Ordered list of UsageJourneySteps that make up the journey. The journey duration is the sum of step durations.
A list of UsageJourneySteps.

Calculated attributes
duration
Total wall-clock time of one journey, equal to the sum of UsageJourneyStep.user_time_spent across all steps.
Example value: 20 min
