The method utilized to visually manage workflows and inventory levels in Lean is Kanban. This approach emphasizes the use of visual signals to indicate the status of a process and to control the flow of work. Kanban boards, often featuring cards representing tasks or inventory, allow teams to see what work is in progress, what has been completed, and what needs to be done next. This visibility helps to facilitate communication and collaboration among team members, enhancing the overall workflow efficiency.

Kanban is particularly effective in managing inventory because it allows teams to respond to actual demand rather than relying on forecasts. When inventory is low, the visual signals prompt action to replenish it, thereby reducing waste and improving just-in-time production.

In contrast, 5S is a methodology focused on organizing and maintaining a clean and efficient workspace, while continuous improvement pertains to the ongoing effort to enhance processes over time, and value stream mapping is a technique used to analyze and design the flow of materials and information. Though these methods support Lean principles, they do not primarily serve the function of visually managing workflows and inventory like Kanban does.
