Group composition is the mix of members’ skills and abilities. Diversity provides group benefits, but it is tough to get it right. Regardless of type and size, group or team performance is affected by the composition. Without the right mix of skills and abilities, a group will not perform at high levels.

When selecting group or team members, be sure to include diverse individuals. You want members with complementary skills rather than people with the same skills. Cross-functional teams are likely to provide diversity and complementary skills.
