The organization structure that is efficient but with many layers of management is the matrix organization line organization line-and-staff organization

The correct answer is the matrix organization.<br /><br />A matrix organization is a type of organizational structure that combines elements of both functional and project-based structures. It has multiple layers of management, with individuals reporting to more than one manager or supervisor. This structure allows for efficient communication and collaboration between different departments or teams, as well as flexibility in resource allocation.<br /><br />In a matrix organization, employees have dual reporting relationships - typically to both a functional manager and a project or product manager. This dual reporting structure helps to balance the needs of the organization as a whole with the needs of individual projects or products.<br /><br />The matrix organization structure is often used in large, complex organizations where there is a need for specialized expertise and collaboration across different departments or teams. It can be particularly effective in industries such as technology, engineering, and consulting, where projects often require input and coordination from multiple stakeholders.<br /><br />In contrast, a line organization has a more traditional hierarchical structure with a clear chain of command, and a line-and-staff organization combines elements of both line and staff organizations, with staff departments providing support and advice to the line departments.
