This study explores the theoretical frameworks shaping organisational design, focusing on their interplay and impact on strategic decision-making. A literature review examines key elements such as strategy, environment, processes, people, leadership, and information systems. The research proposes a conceptual model that integrates insights from various theories, offering a roadmap for aligning these elements to achieve organisational design excellence. The model highlights the dynamic interaction of these factors, guiding organisations in making resilient and adaptable design decisions. While providing a comprehensive overview, the study acknowledges its limitations due to the scope of the available literature and the potential variation in the model’s applicability across different organisational contexts.
