The role is a balance between meaning and reality for the individual. When teamwork starts, many people don’t know what they want or can get. As time goes on, those who find a role will stay, and those who can’t find one will leave. Therefore, the position balances contribution and demand to the team. With the development of the group, everyone is contributing their value and asking for the rewards they think they deserve, but everyone’s views on contributions and requests are not consistent. Through continuous communication, experimentation, and running-in, people who can persuade others to find their roles will stay, and those who can’t find them will leave.
