摘要:The environment in which managers currently operate is dynamic and turbulent. This fact affects the great complexity and dynamism of changes. Thus, decision-making becomes more complex in the context of sustainability. Decisive decision-making is becoming rare, and the challenge of globalization is increasing. Under its influence, decision-making is no longer deterministic. Decision-making processes prevail in conditions of uncertainty. In this context, there is a very intense need to be acquainted with progressive tools to support decision-making and management and to apply the acquired knowledge in practice. This paper focuses on three related areas. We are talking about knowledge management in connection with the most important contributing element—decision-making with quality management. We deal with the characteristics of the individual areas, defining their mutual relationship on a systemic basis. The paper also points to the necessary connection between theory and practice. More specifically, it points to the practical applications of management to decision-making as a managerial function and, at the same time, related to decision-making in quality management. Subsequently, we define the links to knowledge management with an emphasis on the use of procedures, methods, and knowledge in the decision-making process, which we use in theory and practice in quality management.
