A survey design was adopted for this study. Primary and secondary data was used in generating data for this research. Ten (10) deposit-money banks were selected from the population of existing deposit-money banks in South East, Nigeria, with a population of 18, 929 staff. Three Hundred and ninety two (392) sample representatives were derived from the population through Taro Yamane formula.  A stratified random sampling procedure was used to select sample respondents from banks in each state. The main instrument for data collection was a structured questionnaire designed in a 5-point Likert scale. The researcher made use of both inferential and descriptive statistics to analyze the collected data for the research. Regression was used to test hypotheses i, ii and iii, hypotheses iv was tested using spearman correlation and ANOVA was used to test hypotheses v and vi respectively. The findings of the study which was derived from tested hypotheses revealed that there is significant relationship between cohesive leadership system and market share in the selected deposit-money banks in South East Nigeria (r = 0.705, p < 0.05); there is significant relationship between role integration system and profitability in the selected deposit-money banks in South East Nigeria (r = 0.490, p < 0.05); mutual communication affects the revenue growth of the selected deposit-money banks in south East Nigeria (R = 0.557, p < 0.05); there is significant relationship between team-based management system and customer satisfaction  in the selected deposit-money banks in South East Nigeria (r = 0.682, p < 0.05); collaboration has significant effect on the effectiveness of the selected deposit-money banks in South East Nigeria (R = 0.859, p < 0.05); and team size, team leadership, trust, team heterogeneity and commitment are factors affecting team-based management system in the selected deposit-money banks in South East Nigeria (p < 0.05).
