    1 2 Assumed Behavior Hands-on Time!
  24. Time! Human Human Predicate Object Predicate Object System A B

    C 1 2 Assumed Behavior 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
  25. Pro Hint :-) Don't "model" Tell a story

  28. Drafting a blockchain workflow for a steel industry startup Simple

    customer interaction scenario 1 Scenario with resellers involved 2
  29. Some results from EventStorming Capturing two detail "stories" 1 2

    3 Getting side-tracked :-) Considering a few deliverables 4 Discussing billing improvements for a telco provider
  30. My take on some strengths of the approach - Record

    natural language (even without immediate full understanding) - Improve upon single terms and prepare your ubiquitous language (DDD) - Work close to some individual's human perspective, perfect for interviews - Focus on just one single example sequence of all possible activities - Clarify problems and exceptions – just by adding assumptions or events - Discuss alternatives – just by taking a picture and rearranging stickies
