\r\nGantt Charts<\/h3>\r\nhttps:\/\/youtu.be\/N92TOmT_Mcc\r\n\r\nA Gantt chart\u2014<\/span><\/span>named after the designer Henry Gantt\u2014is an easy-to-use graphical tool that helps operations managers determine the status of projects. Let\u2019s say that you\u2019re in charge of making the \u201chiking bear\u201d that we ordered earlier from the Vermont Teddy Bear Company. 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. Our Gantt chart tells us that by day six, all accessories and clothing have been made. The stuffing and sewing, however (which must be finished before the bears are dressed), isn\u2019t scheduled for completion until the end of day eight. As operations manager, you\u2019ll 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.\r\n\r\n[caption id=\"attachment_5924\" align=\"aligncenter\" width=\"1024\"]

Figure 1. Gantt Chart for Vermont Teddy Bear[\/caption]\r\n\r\n<\/div>\r\n<\/div>\r\n\r\nPERT Charts<\/h3>\r\nGantt charts are useful when the production process is fairly simple and the activities aren\u2019t interrelated. For more complex schedules, operations managers may use PERT charts<\/span><\/span>. PERT (which stands for Program Evaluation and Review Technique<\/em>) is designed to diagram the activities required to produce a good, specify the time required to perform each activity in the process, and organize activities in the most efficient sequence. It also identifies a critical path<\/em>: the sequence of activities that will entail the greatest amount of time. Figure 2, \"PERT Chart for Vermont Teddy Bear,\" below, is a PERT diagram showing the same process for producing one \u201chiker\u201d bear at Vermont Teddy Bear.\r\n\r\n[caption id=\"attachment_5925\" align=\"aligncenter\" width=\"1024\"]![\"From](\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/1120\/2016\/06\/17210728\/bearprocess-1024x558.jpg\")
Figure 2. PERT Chart for Vermont Teddy Bear[\/caption]\r\n\r\n<\/div>\r\nOur PERT chart shows how the activities involved in making a single bear are related. It indicates that the production process begins at the cutting station. Next, the fur that\u2019s 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\u2019s clothes are being cut and sewn and its T-shirt is being embroidered. Its backpack and tent accessories are also being made at the same time. Note that fur, clothes, and accessories all meet at the dressing station, where the bear is dressed and outfitted with its backpack. Finally, the finished bear is packaged and shipped to the customer\u2019s house.\r\n\r\nWhat was the critical path in this process? The path that took the longest amount of time was the sequence that included cutting, stuffing, dressing, packaging, and shipping\u2014a sequence of steps taking sixty-five minutes. If you wanted to produce a bear more quickly, you\u2019d have to save time on this path. Even if you saved the time on any of the other paths\u2014say, the sequence of steps involved in cutting, sewing, and embroidering the bear\u2019s clothes\u2014you still wouldn\u2019t 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.\r\n\r\n\r\nKEY TAKEAWAYS<\/h3>\r\n\r\n\t- Gantt and PERT charts are two of the most common graphical tools used by operations managers to diagram the activities involved in producing goods.<\/li>\r\n\t
