Hi would it help to look at this in reverse ..
What would happen if each team member didn't understand or couldn't support the roles and responsibilities of others.
Would this be ok?
Would it make a difference to how everyone worked together?
Would outcomes be the same, better or suffer due to a lack of understanding/inability to support others?
What could be done to try and ensure everyone did feel able to support others, understanding everything involved.
Do you have access to what everyone is expected to do - when & where: their roles and responsibilities?
Access in this way is one important way to ensure everyone understands and can offer support.
Knowing what others are doing avoids unnecessary duplication/deployment - eg: a frill drill procedure?
Where would everyone line up in a fire drill in no one knew who was taking who out or where/what their place was - role in an evacuation process.
Knowing policies and procedures ensures everyone is working together for the benefit of the setting, children, parents and staff.
Not understanding or supporting could cause damage to reputation, jeopardise the safety of children, upset the children, parents and staff.
Debriefing is a military example that shows how important information sharing is for security and teamwork.
