Global organizations have evolved several structures to operate efficiently on a global scale. These include functional, product, geographic, and matrix structures. The functional structure groups activities by department worldwide, while the product structure groups them by product lines. The geographic structure organizes them by region. The matrix structure combines multiple dimensions like products and regions. Emerging transnational network structures eliminate boundaries, linking subsidiaries globally through specialized operations and interdependent relationships. The choice of structure impacts decision making, work processes, and business performance.
