Process control Statistician

The development and use of statistics and statistical theories about distributions and how they vary has become the corner stone of process improvement. SPC is based on the understanding of variation and how it effects the output of any process. Variation is the amount of deviation from a design nominal value. Not every product that is produced will exactly match it's design nominal values. That's why we have tolerances on the nominal values to judge whether a product is acceptable or not. But the closer we are to the nominal value the better the product is. Control charts are one SPC tool that enables us to monitor and control process variation.
