because they need to control the timing of all operations, managers set up schedules: they select jobs to be performed during the production process, assign tasks to work groups, set timetables for the completion of tasks, and make sure that resources will be available when and where they’re needed. we’ll focus on two of the most common: gantt and pert charts. figure 1, “gantt chart for vermont teddy bear,” below, is a gantt chart for the production of one hundred of these bears. as you can see, it shows that several activities must be completed before the bears are dressed: the fur has to be cut, stuffed, and sewn; and the clothes and accessories must be made. as operations manager, you’ll have to pay close attention to the progress of the stuffing and sewing operations to ensure that finished products are ready for shipment by their scheduled date. gantt charts are useful when the production process is fairly simple and the activities aren’t interrelated. it also identifies a critical path: the sequence of activities that will entail the greatest amount of time.
our pert chart shows how the activities involved in making a single bear are related. next, the fur that’s been cut for this particular bear moves first to the stuffing and sewing stations and then to the dressing station. at the same time that its fur is moving through this sequence of steps, the bear’s clothes are being cut and sewn and its t-shirt is being embroidered. finally, the finished bear is packaged and shipped to the customer’s house. the path that took the longest amount of time was the sequence that included cutting, stuffing, dressing, packaging, and shipping—a sequence of steps taking sixty-five minutes. even if you saved the time on any of the other paths—say, the sequence of steps involved in cutting, sewing, and embroidering the bear’s clothes—you still wouldn’t finish the entire job any sooner: the finished clothes would just have to wait for the fur to be stuffed and sewn and moved to the dressing station. in other words, we can gain efficiency only by improving our performance on one or more of the activities along the critical path. this short quiz does not count toward your grade in the class, and you can retake it an unlimited number of times.
