title: Lean manufacturing
context: Lean manufacturing or lean production, often simply "lean", is a systematic method for waste minimization (known by"Muda") within a manufacturing system without sacrificing productivity, which can cause problems.  Lean also takes into account waste created through overburden ( the "Muri") and waste created through unevenness in work loads (the "Mura"). Working from the perspective of the client who consumes a product or service, "value" is any action or process that a customer would be willing to pay for.
