lean,”Specify value from the standpoint of the end customer for each product Identify all the steps in the value stream for each product, eliminating whenever possible those steps that do not create value.Make the value-creating steps occur in tight sequence so the product will flow smoothly toward the customer.As flow is introduced, let customers pull value from the next upstream activity.As value is specified, value streams are identified, wasted steps are removed, and flow and pull are introduced

begin the process again and continue it until a state of perfection is reached in which perfect value is created with no waste.Lean principles consist of:1. define value2. Map Value Stream3. Create Flow4. Establish Pull5. Pursuit Perfection”
