What is Visual Control?

Road traffic safety is an example of visual controls

The ultimate goal of 5S is to create a visual workplace. Visual controls make problems visible, communicate status, and improve performance. They also guide people to stop or prevent abnormalities.

A key component of road traffic safety is the group of lane markings, traffic signs, and signals. Think about a street’s intersection. The traffic light and pedestrian crosswalk are visual controls. As a driver, if you are facing a red line, you know that your right of way has ended, and you stop. A pedestrian uses the pedestrian signals to know when it is safe to cross. In the workplace, you can use visual controls to warn when it is time to buy more office paper or to communicate that help is needed.

Everybody in the work area understands the visual control objectives and knows what to do with the information. They work because when looking at them, everybody understands the same thing and act the same way.

If you use a chart to show orders completed per hour, you should be able to know if there are delays by looking at it. What you see will tell you if there is a reason to hurry up or just relax and keep your pace. Another example is the red tags used in the Red Tag Campaign as part of 5S. These red labels indicate that something was out of place, and call your attention for action.

If you want to create visual controls remember the following:

  • Make the team part of the visual control design process.
  • It must be visible at a distance, choose wisely the font type, color, and size.
  • Avoid cluttered signs and charts, it has to be easy to understand.
  • Use color code and fewer words whenever is possible.
  • Visuals communicate a standard and actual performance.
  • Ensure that the entire team knows what it is, the objective and rules. Even when they participate in the design process, a meeting or training to share those details is important. This will ensure everybody understands the same thing and reacts the same way to the signals.

In future posts, I will talk more about examples. For now, look around and identify visual controls around. Think about how you can apply this tool in your business. Any ideas?
