Good question. My first thought is that if a participant is reluctant to share self-feedback, there might be a trust issue with the team lead, the group, or the organization as a whole. It provides an interesting coaching conversation around whether there is trust within the team, how does that show up, what does trust mean for the team, and what behaviors indicate trust. I wouldn’t single out any one person as part of the process, though the group might do that on their own. It’s tougher with a cultural lens, and so the conversation can center around behaviors that serve the team well, and behaviors that don’t.
The authority dynamic and what team members feel inclined to do based on authority’s presence is a great on-going conversation.
