It’s helpful for new employees to get feedback on how they’re doing in order to adjust to their new workspace. In traditional companies this might be done by a team lead or superior. In Scrum – as so many other rights and duties – this falls to the team.
Although new members tend to come up as a topic in the team retrospective, it’s usually as a side note and only after they’ve just started. We felt that on boarding new colleagues is important enough to give each their own dedicated retrospective with the following structure:
All team members but the new one meet and collect feedback in 3 categories: “Behavior we’d like to see the same amount of”, “More of” and “Less of” (SaMoLo). They discuss the issues, group them and decide who will present the feedback. Then the new colleague joins to hear and discuss what they’re doing great and where they can improve.
