Chapter 3
Scenario-Based Modeling
As we explained in the previous chapter, the pictographic language gets by without symbols for conditionals, variations, or alternatives. With Domain Storytelling, you model just the most important alternatives—each one as an individual domain story. As Cyrille Martraire put it in Living Documentation, “One diagram, one story” [Martraire 2019]. If you are used to flowcharts, BPMN, or UML activity diagrams, a diagram that shows just one possible path might seems awkward at first. However, a UML sequence diagram does exactly it—shows a single path of execution. Actually, scenario-based modeling has a long tradition in software development. Use cases, for example, are also scenario-based.
