WHAT IS IT?▪ Lean principles are derived from the Japanese manufacturing industry.

▪ Lean manufacturing builds on their experiences, including learning from their mistakes.

▪ Lean is the set of "tools" that assist in the identification and steady elimination of waste. As waste is eliminated quality improves while production time and cost are reduced.

GUIDING PRINCIPLESELIMINATION OF WASTE

▪ Over ProductionWaste of Unnecessary MotionWaste of Inventory Production of Defects Waste of Waiting Waste of TransportationWaste of Overprocessing

CONTINOUS IMPROVING

▪ is arguably the most critical principle of lean manufacturing. The changes can be big or small but must lend itself toward improvement.

GUIDING PRINCIPLESRESPECT FOR HUMANITY

▪ he most valuable resource to any company are the people who work for it. Some of the methods to ensure your people know you respect them is through constant communication, praise of a job well done, listening to their ideas and helping out when necessary.

LEVELIZED PRODUCTION

▪ The basis of this principle is that the work load is the same (or level) every day. The key ingredient for this lean manufacturing principle is utilization of a pull system.

GUIDING PRINCIPLESJUST IN TIME PRODUCTION

▪ The basis behind this principle is to build what is required, when it is required and in the quantity required.

QUALITY BUILT IN

▪ The idea behind this principle is that quality is built into the manufacturing process. Quality is built into the design of the part.
