We all know that teams typically outperform individuals. Teams tend to perform better not only because they devote more people to work on a task but also because they bring together various set of skills and perspectives to create a multiplying effect. More minds are better than one, right? Not always.
According to a watershed study, a “Goldilocks” sized team – one that is not too small and not too big – is 4.6 people, which in the real world rounds up to 5. Another recent research revealed that after the 7th person in a decision-making group, each additional member reduces decision effectiveness by 10%. The broader consensus thus goes fifty-fifty, with an ideal team size of about 6 people.
