This study examines the cultural dimensions of 3 companies: CAC-Bank, Turkish Airlines, and Fajr-e-Jam Gas Refining Co. Using a multiple case study approach, the research provides an in-depth analysis of cultural dimensions such as involvement, cooperation, information systems, learning, client care, adaptability, strategic direction, rewards and incentives, control systems, agreement, communication, and coordination. The findings highlight the multidimensional nature of organizational culture and its significant impact on corporate dynamics. While organizational culture is inherently complex and challenging to fully analyze due to time and data constraints, understanding these dimensions remains crucial. A well-defined corporate culture positively impacts performance, fostering growth and globalization. Furthermore, this study reveals cultural variations at the organizational level based on the size, type, and age of the firm. A strong organizational culture increases employee productivity and engagement, whereas a weak culture may have adverse effects. Additionally, insights into cultural dimensions benefit stakeholders, including investors and customers, by providing a deeper understanding of a company's values and practices.
