Visual controls are tools used in workplaces to enhance communication and efficiency by displaying information clearly and intuitively. They often include signs, labels, charts, and color-coded systems that help employees quickly understand processes, status, and safety protocols. By making information visible, visual controls reduce the need for verbal instructions and minimize errors. These controls are commonly used in methodologies like Lean Manufacturing and Six Sigma, where they support continuous improvement efforts. They help teams identify issues at a glance, streamline workflows, and maintain organization. Overall, visual controls contribute to a more productive and safer work environment.
