Group collaborations actually have a low rate of success and productivity—unless you follow the above two rules. These rules will encourage people (no matter what age!) to work conducively in a group, as you are both allowing them to play to their strengths and giving them the option of working alone should they feel like it.
Actively seek out symbiotic introvert-extrovert relationships.
Leadership and other tasks can then be divided according to people’s natural strengths and temperaments.
Allow people to interact freely and retire to their personal workspaces at will.
People need to work with others, but sometimes they also need to work alone.
