3. Project Team 191 Mission To examine the potential for the use of Lean Principles that were developed in the manufacturing industry for adaptation and use in the engineer-procure- construct (EPC) industry.

4. The Power of Lean “Catch up with America in three years. Otherwise the automobile industry of Japan will not survive.” ― Kiichiro Toyoda Founder, Toyota Motor Co. 1894-1952

5. Lean in Manufacturing Five Principles of Lean Manufacturing: 1.Precisely specify value by specific product. 2.Identify the value stream for each product. 3.Make value flow without interruptions. 4.Let the customer pull value from the producer. 5.Pursue perfection. ― James P. Womack Founder, Lean Enterprise Institute
