Which term describes a hierarchical, up and down organizational structure with clearly defined tasks and responsibilities?

The term that best describes a hierarchical, up-and-down organizational structure with clearly defined tasks and responsibilities is a vertical organization. This type of structure emphasizes a clear chain of command where authority flows from top management down to lower levels in the organization. Each level typically has specific roles and responsibilities which are explicitly defined, ensuring that everyone understands their duties and reporting relationships.

In contrast, a matrix organization combines functional and project-based structures, leading to more complexity and potential confusion over authority. A flat organization minimizes levels of management to create a more horizontal structure, often promoting broader roles and responsibilities without strict hierarchies. A network organization relies on a flexible arrangement with numerous interconnections and collaborations, lacking a strict vertical chain of command. Thus, the vertical organization is distinguished by its clear hierarchal delineation.
