A scenario is a set of if-then rules, also called triggers, that defines the initial state (number of capabilities,
resources and their properties, etc.) and the way in which the Kanban network evolves over time. Every scenario
describes the creation of new WIs (that includes their properties, dependencies and prerequisites), and their changes
over the course of their life cycle. In the KSS simulator (program implementation of the simulation model), each
scenario is an xml file that contains these triggers.
