The Benefits of Statistical Process Control: Part One

The Benefits of Statistical Process Control: Part One

No matter what line of business you are in—from retail to hospitality to technology to finance—it’s imperative to prevent business problems before they occur. That can mean something as simple as avoiding the loss of one of your customers to poor customer service or as critical as preventing a botched manufacturing job on one of your flagship offerings.

Thankfully, when it comes to the latter, there are enhanced methods that companies can employ to assure manufacturing quality control—such as statistical process control (SPC).
 
SPC refers to a scientific, data-driven method for quality analysis and improvement that allows you to prevent problems from occurring. One of he advantages of SPC is the ability to use it for analysis through control charts—visual diagrams that track shop floor processes and detect issues, variances, and defects in real time.
 
Today, we explore the how the top benefits of control charts on the manufacturing shop floor.
 

1. Real-time SPC helps reduce the margin of error

Because control charts reveal what’s going on in a manufacturing line in real time, they allow operators to detect and correct issues before they cause deeper problems in processes and products. This greatly reduces the need for product rework or additional product expenditures to fix an offering.
 
“Control charts serve as the early warning detection system in your real-time monitoring software, telling you that now is the time to go in and make a change,” says Steve Wise, vice president of Statistical Methods for InfinityQS. “That way, you don’t finish the whole run only to find out you should have made adjustments three hours ago and now have to eat the costs associated with this problem.”
 

2. Visibility into quality data prevents over-tampering

It is just as important to know when your process is running smoothly as it is to know when something is wrong. Specifically, when trying to detect whether a problem exists, operators can quite frequently over-tamper with a process that was running correctly, which can lead to more variances.
 
After analyzing a control chart, operators need to determine whether to “do something” (adjust a behavior in the process) or “do nothing” (let the process run as is). Often, learning that they can do nothing prevents operators from over-tampering with their processes—another advantage of SPC.

In Benefits of Statistical Process Control: Part Two, we explore how statistical process control supports better decision making throughout the manufacturing organization.

Editorial standards

Fact-checking & editorial guidelines

Every article on advantive.com is written and reviewed against an internal accuracy standard before publication. Here's what that means in practice.

  • Product claims are verified by the brand team that owns the platform.

    When an article references InfinityQS, WinSPC, PQ Systems, Pinpoint, ParityFactory, ProPlanner, KiwiPlan, DDI System, VeraCore, or any of Advantive's other specialty platforms, the relevant product team checks technical statements about features, deployment, and current capability before the article goes live.

  • External statistics cite their source inline.

    When an article references industry survey results, regulatory benchmarks, or third-party research, the source is linked at the point of citation. Statements without an inline source link are first-party observations drawn from Advantive's product teams or customer base.

  • Publication and revision dates stay visible.

    The original publication date and the most recent revision date are both shown on every article. Topics that change quickly — AI capabilities, regulatory rules, product roadmaps — are revisited on a tighter cadence than evergreen reference content.

  • Corrections are issued openly.

    If a factual error is reported, the article is updated, the revision date advances, and material corrections are noted at the bottom of the article so readers can see what changed and when.
