Kanban is a method for controlling the flow of materials and information in construction projects. In lean construction, Kanban is used to reduce waste and increase the efficiency of construction processes.

The main principles of Kanban are

• Visualization: Kanban uses visual aids such as Kanban boards or cards to illustrate the flow of materials and information in the construction project and to make the project status recognizable at a glance.
• Pull principle: With Kanban, materials and information are provided on the basis of actual demand and not on the basis of forecasts. This helps to minimize overproduction and warehousing.

The advantages of Kanban in Lean Construction include:

• Reduction of waste: By applying the pull principle and optimizing material and information flows, Kanban helps to minimize waste.
• Improved transparency and communication: The visualization of workflows and project status promotes transparency and improves communication between those involved in the project.
• Greater efficiency and flexibility: The efficient control of material and information flows enables a faster response to changes and greater adaptability in construction projects.
