  6. The Five Principles • Specify value from the standpoint of the end customer by product family. • Identify all the steps in the value stream for each product family, eliminating every step and every action and every practice that does not create value. • Make the remaining value-creating steps occur in a tight and integrated sequence so the product will flow smoothly toward the customer. • As flow is introduced, let customers pull value from the next upstream activity. • As these steps lead to greater transparency, enabling managers and teams to eliminate further waste, pursue perfection through continuous improvement. http://www.lean.org/WhatsLean/Principles.cfm#specify
