This exploratory study focused on the impact of cultural intelligence (CQ) on team effectiveness (TE) in a multinational, organization development graduate program. This field study included preliminary measures of both CQ and TE, an educational and focus group intervention for enhanced CQ skills, and post-CQ and TE reassessment. The results suggest that CQ skills, specifically Metacognitive CQ and Behavioral CQ, had a positive relationship on a team's ability to meet objectives and satisfy customers' needs in cross-cultural engagements. Curiously, Metacognitive CQ seemed to have diminished a team's ability to deliver results in a timely manner. Demographics such as age negatively influenced goal achievement, while past cultural experiences enhanced execution. The longitudinal aspect of the study found that only improved Cognitive CQ's capability over time correlated to a positive impact on perceived satisfaction of customers and quality of products and services delivered. The education intervention's effect on CQ was inconclusive.
