This case study examines the difficulties multinational corporations (MNCs) encounter when sharing knowledge among their various business units. The study pinpoints four main challenges to knowledge transfer: the hoarding-of-expertise challenge (HEC), the foreigner challenge (FC), the not-invented-here challenge (NIH), and the absorptive capacity challenge (ACC) and presents approaches to tackle these issues. The case study centers around the A&A hotel chain, specifically its subsidiary, “Maria the Great Hotel,” located on Kish Island in Iran. The study identified challenges within the context of this multinational hotel chain. It introduced strategies that can be used to address these challenges, emphasizing the significance of knowledge transfer in attaining organizational success and gaining a competitive edge.
