SPC Simplified

In the 1920s while working at Bell Labs, Dr Walter Shewhart came up with a breakthrough idea: what if we turn the bell shaped curve on its side and draw lines to know when a work process is stable, predictable and in control? For nearly 100 years, the SPC chart has made it possible to improve quality at lower cost in order to raise the standard of living of people all over the world.

Statistical Process Control

Without Statistical Process Control (SPC), we would not have affordable global telecommunications, consumer electronics and many other goods and services we purchase everyday. Simply put, SPC is a way of using data to predict and improve quality and productivity by making things right the first time.

When quality and productivity are high, there is less inspection and rework, which lowers costs. Lower costs can be passed on as savings to customers in order to grow market share. Lower prices help to raise the standard of living for society.
