Last Planner System

A production planning and control model for construction that organizes short‑term work by obtaining collaborative, time‑bound commitments from trade teams, using pull‑style lookahead planning to identify sequenceable tasks and remove constraints, and measuring commitment reliability so as to increase workflow predictability and reduce rework.

A collaborative production planning and control method for construction projects that engages those who commit to perform work (the ‘last planners’) to produce reliable short‑term plans, identify and remove constraints, and improve workflow predictability through lookahead planning, weekly work plans and commitment‑based coordination.
