SPC Overview

Why do SPC?

SPC is the primary analysis tool of quality improvement. It is the applied science that helps you collect, organize and interpret the wide variety of information available to your business. Whether you track revenues, billing errors, or the dimensions of manufactured components, SPC can help you measure, understand and control the variables that affect your business processes.

SPC analyzes the variation in whatever process you are measuring:

  • First, it shows you how consistently your process is performing, and whether you should, or should not, attempt to adjust it.
  • Next, it compares its performance to your customer's requirements, providing an ongoing, accurate direction for quality improvement.
  • Finally, it quickly evaluates the results of quality initiatives designed to improve consistency.

As part of an ongoing cycle of continuous process improvement, SPC can help you fine-tune your process all the way up to the virtually error free Six Sigma level.

SPC is easy to do. Although it involves complex mathematics, computers are ideally suited to the task. They easily collect, organize and store information, calculate answers, and present the results in easy to understand graphs. Computers accept information typed in manually, read from scanners or manufacturing machines, or imported from other computer databases. The resulting graphs can be examined in greater detail, incorporated into reports, or sent across the Internet. A computer collecting information in real time can even detect very subtle changes in a process, and warn you in time to prevent a problem even before it happens.

SPC can help you understand and reduce the variation in any business process. Greater consistency in fulfilling your customer's requirements leads to greater customer satisfaction. Reduced variation in your internal processes leads to less time and money spent on rework and waste. Both directly yield greater profitability and security for your business. SPC is one of the essential tools necessary to maintain an advantage in today's competitive marketplace.
