Spatial layout is an integral part of the process of facilities planning. Facilities planning is concerned with how a specific activity can best be used to obtain a specific goal. One such activity is manufacturing, where the goal is the fabrication of a product. Facilities planning can be divided into a location component and a design component. The latter can be subdivided into systems design, spatial layout design, and material-handling design. Because of the complexity of the problem of facilities planning, each component is usually studied individually and then integrated into the complete system.
