20. Easily explore specific domain scenarios!
21. My Domain Storytelling Scenario o I need to get an understanding of the problem addressed by some work procedures carried out by certain people, BUT … o the people who know the details are domain experts, not trained business analysts, software designers or software developers o discussions tend to end up in details and it is difficult for me to see the wood for the trees, often because of all the "brownfield" we are in o I feel that the real problems and better solutions remain uncovered, because I cannot (yet) even ask the right questions

38. Time! We are a family of four (two parents, two teenagers) and have to take care of shopping on a regular basis. Everybody should help a bit from time to time! Therefore we use a mobile ToDo App with a shared shopping list. All family members can add shopping items to this list, such as e.g. "1 loaf of bread". Items may be marked to be urgently needed on a certain date. The shopping list will then inform all family members about such an urgently needed item. Whoever has time or comes by a suitable shop just marks any bought item as Done in the shopping list. Hands-on #1 Storytelling Visualize the actor's activities sentence by sentence using activity verbs & objects Mobile To Do App Martin Object Activity Verb Object Activity Verb Assumption about behavior Kathi
39. Time! Imagine we shopped a bit too much and need a ride: "Let me see, I could use one of these cars which are now parked everywhere in the city." Our car sharing app allows customers to find nearby cars. One can reserve a car for 15 minutes. When we approach the driver's door with our mobile's NFC, the app asks to confirm the current rate per kilometer. After this, the car opens its doors, and we may start the ride. Finally, when a car is closed from the outside and using the mobile's NFC the ride is finished and our card is charged on a kilometer basis.
