Process departmentalization is used when:

Process departmentalization is indeed used when multiple work processes are needed to complete production. This approach organizes departments around the flow of work or the process by which products or services are created and delivered. In a process departmentalization structure, each department focuses on a specific part of the production process, which allows for greater efficiency and specialization. For example, in a manufacturing setting, one department may specialize in assembly, while another focuses on quality control and another on packaging.

This organizational structure enhances collaboration and communication between departments that are sequentially involved in transforming raw materials into finished products. It is particularly effective for businesses that rely on a continuous production flow, as it streamlines operations and allows for better management of resources and workloads throughout various stages of the production process.
