Lean Project Delivery System: An Update

Abstract

The Lean Project Delivery System emerged in 2000 from theoretical and practical investigations, and is in process of on-going development through experimentation in many parts of the world. In recent years, experiments have focused on the definition and design phase of projects, applying concepts and methods drawn from the Toyota Product Development System, most especially target costing and set based design. These have been adapted for use in the construction industry and integrated with computer modeling and relational forms of contract. Although by no means a finished work, the Lean Project Delivery System has developed sufficiently to warrant an updated description and presentation to industry and academia, incorporating processes and practices that have emerged since earlier publications.
