Storystorming DDD Vienna

Storystorming (https://storystorming.com/) is a toolbox and mashup of existing methods to collaboratively explore user journeys, work procedures and business processes and refine them into working software models. Storystorming facilitates many opportunities for collaboration between business and technology experts, helps them to visually connect the dots and discover what your organisation needs to be successful.

  17. 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

  34. 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.

  35. 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.
