1 List the actions that Smog Co. took to respond to the new demands being placed on it by customers. Group your responses under the headings of stock levels, level of expediting, and storage space. Briefly describe the effects that these actions had on production performance. This is the case of Smog Co., a small supplier of well-engineered components. Smog produces a range of products grouped into families. Production of one of the highervolume product families has been organised into a flow process made up of four steps, which follow one after the other in sequence. Changeover from one product to another is relatively simple, but takes around 10 minutes per machine. To minimise delays caused by changeovers, products tend to be made in batches. These batches move from one step to the next, where they queue on a first in, first out basis to be worked on, after which they move to the next step. This process is shown in Figure 6.6.
