Muda is generally divided into seven types: defects, motion, overproduction, transportation, inventory, overprocessing and waiting.
Defects in the work product have a direct financial impact to the organization. The cost of rework, product loss, quarantining inventory, re-inspection and capacity loss are directly related to amount of product defect. Use of the Continuous Improvement Process (C.P.I.) and increased employee involvement can lead to reduction in product defects and an increase in profitability. The muda of motion involves any motion of people that does not contribute added value to the product or service, examples include; walking extra steps, excess reaching or bending or having to look for something....
