Other Facility Layout Issues • For service firms, however, the facility layout is often duplicated in hundreds or thousands of sites. This makes it extremely important that the layout be designed properly, as changes can be extremely costly. • Also see Supply Chain Design for Multisite Services in Chapter 9.

Types of Facility Layouts
• Product Layout • Advantages of product layouts include lower work-in-process inventories, shorter processing times, less material handling, lower labor skills, and simple planning and control systems. • Disadvantages include a breakdown at one workstation can cause the entire process to shut down, a change in product design or the introduction of new products may require major changes in the layout, and little job satisfaction.
