Despite criticisms, Likert pins his faith in Syatem-4 leadership and interaction-influence networks to diffuse conflict situations and replace win-lose strategies of conflict resolution by win-win strategies, wherein all parties to conflict stand to gain leaving no one frustrated and embittered. System-4 structures and processes help to de-emphasise status, depersonalize problem-solving and use power to resolve conflict constructively instead of suppressing them. The System-4 concepts hold out prospects of development of advance forms of human organization. Some critics may the importance of ‘new patterns of management’ as little more than summary of good management practices. But Likert’s most important contribution to management thought and practice is his systematic analysis of good management practices and extending their frontiers of knowledge and application. He earned his place among management thinkers and researches for laying the empirical foundations for the development of management science.
