Final answer:
The advantage of a product layout in service design is the elimination of bottlenecks, offering a direct flow assembly line arrangement that increases efficiency and productivity.
Step-by-step explanation:
One of the advantages of a product layout approach to service design is the elimination of bottlenecks. This layout is characterized by an arrangement where workstations and equipment are sequenced in a direct flow according to the steps in which a product is made, similar to an assembly line. This setup ensures a streamlined production process, leading to the efficient handling of materials and products, thus minimizing wait times and potential bottlenecks. A product layout allows for increased productivity and leads to a consistency in the products produced, echoing the McDonaldization of society where the automation and standardization are seen to increase the availability and predictability of products. Although product layout offers these advantages, it typically provides less flexibility and is not conducive for customization.
