Instructor: Yuanxin (Amy) Yang Alcocer

Amy has a master's degree in secondary education and has taught math at a public charter high school.

After watching this video lesson, you will see how visual control can be used in the production process to streamline the production of products. You will also see how visual control can be used as a means of quality control of finished products.

Visual Control Definition

All businesses need some form of quality control. Just imagine if a business were to produce products at all levels of quality; some great, some good, and some really bad. Now, imagine that you received one of the really bad products. Would you be happy? Probably not. Would you purchase again? Probably not. Would you recommend the product to others? Probably not. If, on the other hand, a business consistently produced high quality products, then when you receive your great product, you'll be happy with it and will probably order again--and recommend it to your friends.

As you can see, having a quality control process in place to make sure the products being produced are quality is important for the growth and continued success of a business. One method of quality control that businesses can use is visual control. In this method, visual cues are used to indicate whether something is acceptable or not.


Visual control is actually used in many places. For example, your computer gives you visual cues as to what is going on. You have the power LED that tells you whether the computer is on or off. Your class schedule is also an example of visual control because it tells you where you need to go for your classes and in what order.

Another example of visual control used in the quality control process is when a fashion designer, like Sue, looks at her finished new blouse and sees one arm is longer than the other. This visual cue tells Sue that her new blouse needs to be adjusted so both arms are the same length. Sue uses this visual cue in her quality control to ensure that all her blouses come out great!

In Production

Visual control during the production process can help streamline the process and decrease the number of potential problems that can come. Different colored LED lights on the machines used to make the products can signal whether a machine is in working order or when there is something wrong. If you see that a machine is not working by looking at its LED light, you can then go about fixing the machine before too much time is lost.

As the products are in the process of being created, you can also use visual control to ensure that products are produced in the right way. You can have workers compare in process products to a prototype to make sure that the products are being made to specifications. If an in-process product doesn't meet the specifications, then it can be taken out of the production line before more time is lost.
