The Last Planner System® (LPS) is a lean production control system designed to optimize workflow and reduce waste in construction projects. It aims to deliver all promised value to the client by minimizing the usual inefficiencies and resource overburden that often arise from specialized project teams working in isolation. The LPS introduces five recurring conversations—pull-planning, make-ready planning, weekly work planning, daily commitment management, and learning reviews—to ensure a coherent and predictable workflow. These conversations help manage the network of commitments among specialists, ensuring that tasks are planned, executed, and reviewed effectively. The LPS can be applied to both construction and design work, adapting to the specific needs of each. The Lean Construction Institute (LCI) holds the trademark for "Last Planner" to maintain its integrity and ensure proper attribution.The Last Planner System® (LPS) is a lean production control system designed to optimize workflow and reduce waste in construction projects.
