Lean Manufacturing/Service

Lean manufacturing or lean production, which is often known simply as "Lean", is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination (Wikipedia).

Principles of Lean

  1. Specify value at from the standpoint of the end customer.
  2. Identify all of the steps in the value stream for each product family, eliminating whenever possible those steps that do not create value.
  3. Make the value-creating steps occur in tight sequence so the product will flow smoothly toward the customer.
  4. As flow is introduced, let customers pull value from the next upstream activity.
  5. 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.
