lean manufacturing1

six sigma in some book always comes up with lean manufacturing together,but they are not the some phylosiophy, do they should be combined? but have to understand what is lean manufacturing first.

lean manufacturing known as lean production, it is a business philosophy. Toyota Motor Company developed it first,where it was called Toyota production system(TPS).

The objective of of Lean produciton is to eliminate all forms of waste in the production process.

six sigma is aim at creating a stable process, reduce the waste at the design stage. they have very similar objective.

wastes in lean produciton are overproduction, waiting for machines or operators, transportation waste, process waste resulting from inefficient and poorly designed processes, excessive inventory wasted motions through operators leaving work stations to fetch required suppliers or through continuous reaching, searching, or carrying goods. waste of rework through producing defects.

when all these waste is eliminated, the order production life cycle time is compressed. short cycle and delivery time, higher quality, and lower costs are all positive resluts.

there are many techniques to deal with waste work result in a whole that is greater than the sum of the individual techniques. if the manufacturing process is changed, lean manufacturing will produce high-quality products built to customer requirements at lower costs than traditional manufacturing.

    we have started implementing a process of lean production at our manufacturing facility at Cundey Systems the reduction in machine operators time has provided significant savings and moving our factory around has saved alot of time in transporting components between machines. at the moment our lead times are massive but we are hoping to reduce these by using some of the techniques youve mentioned
