In traditional team cultures, feedback has been the sole responsibility of the manager. In Agile teams it’s more important for feedback to be peer-to-peer because the manager doesn’t know the minute-by-minute details of what’s going on within the team. What if managers were not solely responsible for providing guidance for an individuals growth, but rather the team itself? Building feedback into the culture creates a team with a stronger sense of responsibility for one another. They will self-correct interpersonal issues and work-quality issues better and faster than a traditional team.
