I am currently working in a big organizational structure of HCA (Hospital Corporation of America), a hierarchical organizational structure. This company's organizational structure that best fits it would be tall (vertical). A top-down approach, with a clear chain of command from the top level to the bottom, characterizes this type of structure. The advantage of this structure is that it provides clear roles and responsibilities. Everyone knows who they are accountable to, which reduces confusion and ensures that tasks are completed efficiently. However, it's worth noting that this structure can also have some disadvantages. For example, it can lead to a lack of communication between different levels of the organization and slow down decision-making processes because approval may be needed from several levels of management
