This article presents an overview of lean manufacturing, a process by which precast concrete plants can reduce waste and improve their production operations. The authors describe eight types of waste that can be eliminated and identify seven principles that can substantially improve success in the application of lean manufacturing. Many examples from the industry are given to show how waste can be eliminated and plant operations can be improved. Although relatively few PCI member companies are currently using lean manufacturing, those that are applying these techniques are showing that production costs have decreased, rework has been reduced, and production capacity has been enhanced.
