An easy question: All things being equal in terms of the mix of talent, which group is likely to be more successful: one that has five members or one that has fifteen?
The smaller group is likely to do better because:
- Fewer people, fewer ego problems.
- Each member knows that he or she matters. They are less inclined to dodge meetings or not do their homework. They can't hide in the bushes. They play a prominent role.
- Because attendance is better, there are fewer people who have to catch up.
- It's much easier to set up meetings since there are fewer schedules to juggle..
- Decision making is easier since there are fewer factions.
- Communication in general is less complicated. [As an exercise, write down all of the possible relationships in a 15 person group. It's shocking.]
Amazon reportedly has a two pizza rule: Don't have any committee that cannot be fed with two pizzas.
Less can be more.
