    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.

  28. 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
