8. EXAMPLE 1:
DATA-DRIVEN DECISION-MAKING
• A/B-Testing:
• Data gets
collected from
website users
• The algorithm
decides alone
which variant
works best and
should be used in
future.

9. EXAMPLE 2:
DATA-INFORMED DECISION-MAKING
• Here, I track my emotional status and my fitness
(as self-employed I don‘t have to worry about
bosses maybe seeing this data illegitemely)
• With these data points collected, I can i.e. in
monthly analysis see, which clients I am most
happy with. Or at which weekdays or times of day I
feel most vital. And optimize my working
behaviour.

11. • Facts-based instead of gut feeling
• Sustainable
• Goal oriented
• Great to support also goal-oriented structures
