Nonprofit governance models rarely incorporate board intragroup dynamics as a significant board factor that influences performance. However, intragroup dynamics such as cohesion and conflict have demonstrated a relationship with board performance suggesting that board intragroup dynamics play a larger role than previously thought. In order to better understand the relationship between intragroup dynamics and performance, a systematic quantitative literature review was conducted. Through an extensive search process and the application of a series of inclusion criteria, 43 papers were identified and reviewed. Three types of intragroup dynamics (cohesion, the board–CEO relationship, and boardroom climate) were shown to have a positive relationship with performance whereas the relationship between performance and two other intragroup dynamics (conflict and power patterns) was mixed. It was concluded that intragroup dynamics should be a central factor in board governance models. Using the findings of this review, directions for future research were identified.
