5 Preface Modern factory layout began most notably at Highland Park, Michigan. There, Henry Ford and Charles Sorensen first put large-scale flow line production into place. Layout, the arrangement of equipment within the building space, was the most striking feature of Ford production. The layout of Ford factories was so noticeable, it disguised rhe more intangible elements of Ford and Sorensen's highly integrated and wellthought-out manufacturing system. As a result, many factory managers, business executives, and engineers still try to replicate eady Ford layouts. These imitations often are ill-suited to their business purposes. Even when managers do not copy Ford layouts, they continue to believe that layoul is the heart of efficient production. And so it is, but only as the culmination of a rational design process: a process that moves from global location to workstations, from policy to operations. It is a process that includes the entire range of tangible and intangible elements. The result is a design that integrates products, service, people, information, and technology. Our facilities planning approach builds on the pioneeringworkof Richard Muther and Knut Haganas, both ofwhom deleloped systematic layout planning (SLP) and systematic handling analysis (SHA). These concepts remain valid after almost thirty-five years. Our approach uses contemporary language and examples. Data acquisition is stressed. Perhaps most importantly, we integrate manufacturing strategy and manufacturing focus, concepts first put forth bywickham Skinner and first recognized as connected by William Wrennall. This is more than a manufacturing book, however. The concepts originally developed for industry now apply to services. Products and

6 Facilities Planning services meld together in almost everyviabl enterprise in today's world. The concept of "business process" covers all productive human activity. Government, education, the professions, and industry are simply variations on a few central ideas. Therefore, the planning ofa government facility or an idea fzctory follows the same principles and approach as the planning of an automotive factory. The planning of a hospital follows the same course as the planning of a textile mill. A facility project often is the catalyst for new strategies. Under its guise, management may open a strategic debate that brings together the many disparate functions and elements of the enterprise. It can provide the structure for analysis and discussion. The project then translates the results into steel and concrete. In this way, facility planning becomes a large-scale reengineering project rather than an exercise in template shuffling. Our purpose in writing this book is to help practicing industrial engineers new to facility planning. We intend it to be practical with many examples, forms, diagrams, and visual aids. Visual approaches are especially important for facility planning. The human mind is usually more creative in avisual mode. Illustrations, graphs, and charts effectively represent complex spatial arrangements that have many levels of detail. Also, data is more significant for most of us when we can see it. A plant layout is the product ofthousands ofdecisions, both past and present. It is the physical manifestation ofthe firm's manufacturing strategy, whether de facto or otherwise. These decisions cover the entire range of manufacturing-finance, personnel, process' product design, and many, many other topics. We cannot possibly do justice to all of these issues. We hope, however, to alert industrial engineers to their existence and importance. We hope to point the way to more rational and strategically oriented facility design.
