Organizational design enables efficient resource management, which is crucial for achieving goals and maximizing efficiency. By determining who makes decisions and how they are implemented, top managers shape the decision-making processes, consequently influencing employee behaviour and goal realization. Organizational design becomes a key tool for creating effectiveness, allowing managers to build efficient organizations. In complex organizations, organizational design is the cornerstone of competitive advantage, as it allows for the utilization of strengths and minimization of risks. Design provides the foundation for conducting activities and utilizing resources in a way that maximizes the organization's value. Research shows that successful organizational design and alignment of its elements significantly contribute to a company's success and competitiveness. The focus of the paper is to highlight the importance of organizational adaptation during crisis periods through organizational design. The main organizational design model discussed throughout the paper is Galbraith's Star Model. As one of the most well-known and widely used models in organizational design practice, it serves as the foundation for the case study in this paper. Additionally, the paper emphasizes the significance of crisis management and crisis response as integral components of every organization. The paper also investigates the impact of crises on organizational design, highlighting key challenges and potential adaptation strategies such as organizational flexibility and agility. For the purpose of this paper, a detailed case study was conducted on one of Croatia's oldest companies, Varteks d.d. The historical development of the company and the series of crises it has faced were examined, ultimately leading to the challenging current situation of Varteks. Based on the analysis, recommendations were provided at the end of the paper for enhancing organizational design, thereby contributing expertise in the field of organizational design and crisis management research.
