Software development with Scrum makes all team members responsible for the result. Some tasks need coordination, to make sure the tasks will be completed at the end of the sprint the team assigns a person responsible and hands him a token. When starting with this way of handling certain tasks, make it visible.
I just crafted some relay sticks measuring 28 cm in length and 28 mm across (official measurement 38cm, 38mm). I just put some tape around for colour distinction. The team is free to combine a colour with a certain task.
Sticks will be handed over every week. On a day off the stick needs to be handed over as well.
We will use one of these relay sticks to make sure the translation of changes are coordinated and completed in time. Another one will be used for the task of checking the completeness of new issues.
