Several leading technical companies have adopted non-matrix structures to streamline decision-making and maintain clear authority lines. For instance, Apple is renowned for its functional, hierarchical organization that emphasizes product-focused divisions and direct reporting channels. Similarly, Amazon utilizes a streamlined, divisional approach where specific business units operate largely independently under a clear chain of command. These structures support rapid decision-making and accountability, proving effective in environments where clarity and efficiency are prioritized over the complex interdependencies seen in matrix models.
