In a Lean manufacturing process, time and resources spent on conveying data and information are regarded as waste. Visual factory tools—such as signs, charts, check sheets, and more— simplify information and reduce resources and time consumed to make it accessible. Clear and concise real-time information and feedback regarding the status of a plant or a process is provided to shop floor employees using visual cues and tools. The visual cues provide unambiguous information needed to perform their jobs at a glance. Simple visual cues—such as color-coded pipes, wires, or flags; painted floor areas; and indicator lights—are simple to use and understand. The type of tool and the location used are determined by identifying the relevance and the information recipient.
