What is SPC?

In today’s competitive environment, the quality of the products you produce affects your competitiveness. During the manufacturing process, variations can occur at anytime and are often hard to accurately predict. Variations typically result in increased cost of production because of excessive waste and lost man-hours due to re-work or scrap.  

Statisticians have developed a method to monitor and control the processes involved in production to drastically reduce these problems and keep your profitability and quality high. This method is known as Statistical Process Control or SPC. The SPC rules and methodology supporting this method must be properly applied to protect the credibility of the computations. While SPC involves highly complex calculations, data analysis methods, charting and reports, it allows you to make sure that your processes are:

  • stable (A stable process has the ability to consistently produce the same results.)
  • capable (A capable process meets the design specifications.)

What is SPC Software?

What is SPC

Synergy SPC software allows users various ways to proactively monitor the production process.

SPC software drastically reduces the complexity of SPC so you can monitor, find and eliminate variations in the stability and capability of your production processes ASAP without needing a degree in statistics. It simplifies the entire process of SPC for all levels of the production line to ensure you get the best visibility and insight into the accuracy and leanness of your manufacturing processes. The software uses statistical methods to remove the guesswork involved in improving your stability and capability AND it can do it all in real-time.  This means you have visibility into your process and are able to make course corrections at the exact minute and location of any variations.  

Manually gathering data can be time-consuming. However, using real-time Statistical Process Control (SPC) Software, you can automate the data collection process.

“With Synergy 2000, operators take the measurements and push a button and the data is saved and available for review instantly,” said Bob Hyland, Process Engineer, for Acme Aerospace.

SPC software enables a company to predict and prevent defects before they occur. SPC software results in savings for the company by:

  • Reducing scrap
  • Reducing rework
  • Increasing user productivity
  • Efficiently managing the life cycle of your machines
  • Developing new products using existing equipment


Good vs. Great SPC software

When done well, great SPC software should be:

  • Real-time, giving you visibility into deviations that need correction
  • Easy for all members of your manufacturing process to use (shop floor operator, supervisor, manager, engineer, and executive)
  • Tailored to you and your needs

Any good SPC can meet the first two needs. When it comes to being tailored to meet your needs though, there is no question that only Zontec’s SynergySPC products meet the third need.

SPC software also benefits quality personnel, engineering, and management staff by providing them instant insight into production.

“Using the Synergy 1000 SPC software is a lot more user friendly, because you can run SPC in real-time. Now if anything goes out-of-specification, I get an email notification at my desk instead of having to physically be on the shop floor. In the past, we wouldn’t know if we were trending towards being out-of-control or not,” said Brian Brooks, VP of Operations for Domestic Fastener & Forge, Inc. (DFFI).


The Right Tool For the Job

With our SynergySPC suite of real-time products, we are the only SPC software company that has an option for every customer. We don’t believe in a “one size fits all” approach. We believe that each manufacturer has different needs when it comes to SPC software and it would be unethical to sell you a product that’s either more or less than you need. If we just had one product to offer you, you would either be:

  • paying too much for SPC software (because you are buying a product with too much complexity)


  • wasting money (because you are purchasing a product that will not perform as needed)

We don’t believe it’s right to sell you a chainsaw to cut butter and we also don’t believe it’s right to sell you a butter knife when you need to carve a turkey. We believe in giving you the right tool for the job.  


Investment Retention Program

Satisfying your needs as a customer means we stay with you beyond the initial sale. In addition to offering all of the free support you’ll ever need, if you ever outgrow the product you’re using, you’re always able to make the switch to a higher level SynergySPC product without losing a single dollar of your original purchase price. Our Investment Retention Program discounts the cost of any switch you make to a higher level SynergySPC product by your original purchase price. No need to shop for a new system, and no need to run a cost analysis on switching to a bigger system vs. sticking with the current one.  

Our Guarantee

You know quality and process improvement are critical. In as little as TWO WEEKS, Zontec’s SPC software will give you a clear picture of the stability and capability of your manufacturing processes and show you where improvements can be made. Guaranteed! This will lead to an extremely fast return on investment (ROI).

When evaluating an SPC software system, please consider the universal frustrations on your production line along with your future needs. Then consider the user-friendly features of the software. At Zontec, we make implementation and day-to-day use simple and easy but most importantly, we will help you assess which Zontec SynergySPC software product is right for you. We offer the only SPC software solution that is real-time, powerful, easy to use, easy to integrate, and only as complex as you need it to be.
