Teams often come up with “we should communicate better” in their retrospectives. There’s nothing wrong with that. Who can argue against improved communication? You might even see some improvements just by noting the problem. However, the default reaction of a great ScrumMaster in these situations is to ask the team to be specific. Who needs to communicate better with whom? What do they need to communicate better about? When does this communication need to happen? How will we know communication is good enough?
