ABSTRACT
Cohesion influences collaboration between group members. Nederhof and H. Steensma have studied the relationship between role fulfilment within groups and quality of collaboration. All kinds of events that make decision-making necessary take place in organisations. A clear structure can be created by taking into account the phases that have been identified in the processes of problem-solving and decision-making. Effective decision-making in groups can be promoted by two main types of input: task-oriented and group-oriented input. Good leadership of the decision-making process is possible only if the leader has no strong interests or views with respect to the problem to be resolved or the parties in a conflict. In self-managing teams, team members must both perform the work and make decisions. Effective collaboration and joint responsibility for group tasks require a good atmosphere and mutual confidence. If these are lacking, discussion and decision-making will be impeded and there is a danger that some group members will not do their work properly.
