Visual management plays a crucial role in the 5S methodology. It involves using visual cues such as signs, labels, colour-coding, and visual boards to communicate information, improve workflow, and enhance decision-making. Visual management helps employees quickly identify the location of tools, equipment, and materials, understand the status of processes, and notice abnormalities or deviations from standard practices. It contributes to creating a visually controlled workplace where information is easily accessible, aiding in productivity, efficiency, and safety.
