IT consultant Martin shared very understandable non-technical stories about how the scum process should work out and who carries which responsibility.

The story of the baby and the chicken

A male client approaches the product owner because he wants a baby. The product owner asks 'Why do you want a baby? What need do you expect it to fulfill?' The client says 'I want to raise a little creature.'.
The product owner lets the team know what the client desires and the team says 'Okay, there is a man who wants a baby. We need a woman and 9 months of time, then we can give him a baby.'
Equipped with this information provided by the team, the product owner approaches the client again and tells him. The client, however, is not happy with this plan and says 'I don't want to wait for 9 months, i want a baby in 1 month!'
The product owner goes back to the team and tells them what the client said, he does not say that it is impossible on behalf of the team, because that is not what the product owner's job is!
The team then states that since it is not possible to get a baby in one month time by using 9 women, the need to raise a little creature could also be satisfied by a non-human baby, and they propose to use an egg and a hen. After being informed by the product owner again, the client agrees to try this approach.
Now the sprint starts: The hen will sit on the egg for 30 days and is not to be disturbed by the product owner! If the product owner were to say 'Let me see the progress of the chick!' after 15 days already and wanted to have a look at it, the egg would have to be opened and the chick would die.
After 30 days the chick is born and given to the client. The client soon finds, that even if he got what was asked for (a little creature to be raised), the beak is too pointy and the feathers are - although soft - too yellow for his taste. He contacts the product owner again. Time is running out and now, since already one month has passed, the 9 months required for a human baby are definitely too long. Informed by the product owner, the team then comes up with the plan to look for a kind of monkey that could be born after 6 or 7 months, as a compromise closer to a human baby but less time-consuming. The client agrees to this plan. Now after 8 or 9 months from the start of the process; the client has his little - although hairy - creature to raise, has felt well heard and is happy.
