In September of 2009, WM2A began a LEAN journey. LEAN is the application of the Toyota Production System in the design/construction industry. LEAN is IPD on steroids. LEAN recognizes the value of collaboration and employs a systematic set of tools toward eliminating waste in the design/construction process. The elimination of avoidable waste allows a focused investment of scarce resources (time, dollars, materials and creativity) toward enhancing value for the Owner.

The WM2A team has employed several LEAN tools to date on 15 projects including: Pull Planning, Work Registers/Constraint Logs, 5 Why analysis, A3 documentation, Plus/Delta, Hot Topics, Set-based solutions, Biweekly Team Check-in calls, Consensus Doc 300 agreements, Design and Construction Retrospectives, Big Room meetings, CBA analysis, and Target Value design.
