Team effectiveness: Beyond skills and cognitive ability

On the basis of job analysis results, the validity of using measures of gen eral cognitive ability, job-specific skills, and personality traits jointly at both the individual level and the group level to predict the performanc e of 79 four-person, human resource work teams was evaluated. Team member t rait and job skill scares were aggregated with a conjunctive model of task performance. At the individual level of analysis, measures of personality ( i.e., Agreeableness and Conscientiousness) predicted peer ratings of team m ember performance beyond measures of job-specific skills and general cognit ive ability. Similarly, at the group level of analysis, both Agreeableness and Conscientiousness predicted supervisor ratings of work team performance , objective measures of work team accuracy, and work completed. At both the individual and group levels, the trait of Agreeableness predicted Interper sonal Skills.
