Production System designed by Sakichi Toyoda‚ lean manufacturing centers around placing small stockpiles of inventory in strategic locations around the assembly line‚ instead of in centralized warehouses. These small stockpiles are known as kanban‚ and the use of the kanban significantly lowers waste and enhances productivity on the factory floor. In addition to eliminating waste‚ lean manufacturing seeks to provide optimum quality by building in a method whereby each part is examined immediately after manufacture

Statistical process control (SPC) is the application of statistical methods to the monitoring and control of a process to ensure that it operates at its full potential to produce conforming product. Under SPC‚ a process behaves predictably to produce as much conforming product as possible with the least possible waste. While SPC has been applied most frequently to controlling manufacturing lines‚ it applies equally well to any process with a measurable output. Key tools in SPC are control charts

Testing statistical significance is an excellent way to identify probably relevance between a total data set mean/sigma and a smaller sample data set mean/sigma‚ otherwise known as a population mean/sigma and sample data set mean/sigma. This classification of testing is also very useful in proving probable relevance between data samples. Although testing statistical significance is not a 100% fool proof‚ if testing to the 95% probability on two data sets the statistical probability is .25% chance
