1. Focus - a manager can spend more time with each person on a smaller team as necessary.
2. Clarity - in a smaller team, everyone has a line of sight to everyone else. Everyone is aware of the circumstances, the successes, the failures and the expectations.
3. Cohesion - smaller teams have a greater chance to be more cohesive. (The corollary here is they also have a better chance of tearing each other apart)
4. Administration - I need to recruit, train and bring fewer people up the learning curve, so we spend more time on real work and less on the administration of the team
5. Interaction - I can interact more easily with each individual and gain a sense of their commitment level
6. Visibility - Since it is harder to “hide” on a small team, I can quickly weed out those who aren’t up to snuff or just aren’t bought in to the program.
