The role of the industrial engineer in the construction of facilities such as Technicolor's large new film-processing plant is examined. (With a processing capacity of 15 million feet or 4.6 million meters of film per week, this is certainly one of the largest such plants in the world.) People in the areas of plant and operations management are generally “too close” to the problem to be effective designers of such a facility, although their input into the study is a requirement. They may be able to define productivity, but they do not always know how to get it. The industrial engineer is the link between the operational people and the design engineer. Using flow charts, plastic grids and templates, job descriptions and other data, including his personal knowledge of plant operations and procedures, the industrial engineer develops the optimum layout.
