All members of the development teams are part of a unit. Depending on the requirements, they can be implemented using all teams or subset of the teams.
Hints and Tips
For joint team events, the question arises whether each team member should participate of only with representatives. This depends on whether or not all teammembers need to be informed. If all teammembers need to be informed, then a common event is the most efficient way for effective information sharing and decisionmaking. The decision to carry out an event with all or with representatives depends on the individual cases.
There is no need to fear events with many participants, as there are good facilitation methods to ensure qualitative outcome and efficient meetings.
Work events with large groups, however, require a clear structuring and moderation. Here an experienced Master Agility is demanded.
