What is the difference between functional layout and group layout?

Functional layout, also known as process layout, organizes workspaces based on similar tasks or functions, allowing for efficient workflow within departments but potentially leading to longer transport distances between related processes. In contrast, group layout, or cellular layout, clusters different machines and workstations into cells that work on similar products or components, facilitating faster communication and reducing transportation time. This results in improved efficiency and flexibility for production processes. Essentially, functional layout focuses on process optimization while group layout emphasizes product flow.
