A team with one star and nine spectators loses to a team of ten who all know their job.

One excellent person and nine waiting is not a team, it is a soloist with an audience, and it loses to a group where everybody has a job they understand. The deciding factor is rarely the top of the talent range, it is how much of the group is actually taking part. Clarity about roles is what turns attendance into contribution.

Check whether every person in your group can say what their job is without hesitating. Wherever the answer is vague, give them something specific this week. Ten people who know their part beats one carrying everything.
