Lean Manufacturing
Lean Manufacturing

Lean manufacturing is a generic process management philosophy.

 Lean Manufacturing can be seen as a set of potentially competing principles whose goal is cost reduction by the elimination of waste. These principles include:

  • Pull processing: products are pulled from the consumer end (demand) just-in-time to be used, not pushed from the production end (Supply).
  • Perfect first-time quality - quest for zero defects, revealing & solving problems at the source.
  • Waste minimization – eliminating all activities that do not add value & or are safety nets, maximize use of scarce resources (capital, people and land).
  • Continuous improvement – reducing costs, improving quality, increasing productivity and information sharing.
  • Flexibility – producing different mixes or greater diversity of products quickly, without sacrificing efficiency at lower volumes of production.
  • Building and maintaining a long term relationship with suppliers through collaborative risk sharing, cost sharing and information sharing arrangements.
  • Autonomation - if an abnormal situation arises then a machine or person must stop production in order to avoid defective products and other waste.
  • Load levelling and Production flow - fluctuations in product flow increase waste because process capacity must always be prepared for peak production.
  • Visual control - where the actual progress of work in comparison to daily production plans is clearly visible.
