Statistical process control (SPC) is a method for achieving quality control in manufacturing processes. It is a set of methods using statistical tools such as mean, variance and others, to detect whether the process observed is under control.   Statistical process control was pioneered by Walter A. Shewhart and taken up by W. Edwards Deming with significant effect by the Americans during the World War II to improve aircraft production. Deming was also instrumental in introducing SPC techniques into Japanese industry after that war. Classical Quality Control was achieved by observing important properties of the finished ...
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 , a focus on continuous improvement and designed experiments . Much of the power of SPC lies in the ability to examine a process and the sources of variation in that ...

Business ppt » Inventory Accuracy Hints
Often, writings on inventory accuracy improvement focus on techniques, such as cycle counting. While this is a very important item in the toolkit of the inventory or materials professional, cycle counting is only mainly a measurement and diagnostic tool. Think of it as SPC (Statistical Process Control) for inventory accuracy. You probably aren’t going to cycle count your way to inventory accuracy, without also making major improvements in the material handling, transaction control, reporting and feedback process. For many companies, using cycle count adjustments to correct inventory record errors is like trying to bail ... market research, surveys and trends

SPC
Using the "sample standard deviation" (SD), you can then calculate and chart the usual extremes of a process under a given set of conditions.  This variation is "normal" and we cannot reduce the variation without making fundamental changes to the process ( eg going on an advanced drivers course, buying sports suspension, etc.) Because of the properties of the normal distribution it is usual in SPC or quality control applications to multiply the standard deviation by three and then add that to and take it away from the average which gives a confidence level which encompasses 99.73% of the observations or "population". industry trends, business articles and survey research

Overview of continuous quality improvement management tools
Quality improvement is the process of improving the quality of a product or manufacturing operation. Continuous quality improvement is the act of endlessly cycling to improve a process, monitoring it after the changes, and then finding another area to improve. Continuous quality improvement management tools help identify areas requiring improvement. Continuous quality improvement management tools can be used to prioritize problems to solve and identify the root causes that create most of the defects. Continuous quality improvement management tools can take the form of check sheets, charts, and diagrams. Charts Continuous quality ... market trends, news research and surveys resources
