Hossain MA, Uddin MK, Hasan MR, Hasan MF (2018) Conflict management on the organizational performance: a synthesis of literature. J. Innov. Dev. Strategy. 12(1), 56-67. The aim of this study is to unfold the research findings through a synthesis of literature on conflict management and organizational performance. Conflict means a clash of opinions in the simplest term. It is clear that the clash of opinions will be everywhere if the human is there and this will cause conflicts. This study has incorporated the clear concept of conflict, organizational conflict, conflict management and the organizational performance. Moreover, this research work has tried to emphasize on the importance of the issue of conflict in the organization by focusing on nature, types, causes, process, several styles, as well as models of the conflicts. A large number of studies collected from various sources and then synthesized. The literature collected provided three approaches, traditional approach, behavioral approach, and interactionist approach. The researchers showed that two common types of conflicts, vertical and horizontal are faced by the managers in the organizations. Vertical conflict is observed in groups while horizontal occurs between persons at the similar level. Besides, researches have incorporated more types of conflicts, such as affective conflict, substantive conflict, conflict of interest, conflict of values, goal conflict, realistic conflict vs. nonrealistic conflict, institutionalized vs. non-institutionalized conflict, retributive conflict, misattributed conflict, displaced conflict etc. From the synthesis of the previous articles, it is understood that if conflict handled or managed exactly will increase the performance and productivity of the organization while poor conflict management has a negative phenomenon. This article noted that it may be a good habit to see conflict as a process not to look at the conflicting parties. This study has extracted a theoretical model of organizational conflict which comprises with specifically interpersonal, intragroup, and intergroup conflicts. Scholars in this field think that this theoretical model will enable an organizational interventionist to manage conflict effectively. The study also has observed that there is a significant relationship between conflict management styles (collective bargaining, compromise and accommodation) and organizational performance. The nature of this relation has indicated that when conflict is within the control and at an optimum level the organizational performance is the highest. Non-integrative conflict management strategies (competition, domination, and avoidance) had a negative effect on organizational performance. Finally, this study concluded that conflict was an unavoidable phenomenon in organizational life and it could contribute to or detract from organizational performance depending on the conflict management methods adopted in the workplace.
