3 Practices of Companies Who Effectively Reduce Variation Cost | Quality Insight

We find that there are 3 common practices among companies who are effectively minimizing process variation. (1) Real-time monitoring of manufacturing with operator access to data. (2) Visualization of process output for operators and supervisors. (3) Investigation into problems and prioritization of improvement initiatives.

Our discussion begins at 21:42 in the video.

Real-time Monitoring of Manufacturing with Operator Access to Data

Many companies try to monitor manufacturing with a paper and pencil approach, but end up realizing this method doesn’t give them the feedback loops or the improvements they were striving for.

Plus, it can be time consuming and cumbersome for someone outside the department to analyze or even look at the data.

Instead, the companies we see successfully minimizing process variation focus on using real-time monitoring by using software on the factory floor that can collect data from CMMs, scales, micrometers, and other production devices.

The companies use software to help them better detect trends and special causes underlying production issues or scrap/rework concerns.

A real-time SPC system uses statistical rules to identify the source of waste in a timely manner. Operators are alerted so that problems can be appraised and worked through or prioritized as they come up.

Visualization of Process Output for Operators and Supervisors

In a typical manufacturing plant there are hundreds of characteristics to monitor. The operators are usually focused on only the few characteristics that impact the production area they are responsible for.

To identify broader sources of variation, managers usually use some type of plant-wide or summary view. With a dashboard style view, problems become immediately visible, making rapid response a much more likely outcome.

Investigation Into Problems and Prioritization of Improvement Initiatives

The companies we see successfully reducing process variation start by taking all their historical data from their real-time monitoring systems, and searching for excessive variation. The goal here is to expose opportunities that would have otherwise gone unnoticed.

One company in the food packaging industry was able to analyze their historical production data not by product or process, but instead by fill heads and operators. They identified a situation where operators were making changes to the line that resulted in more variation, not less. It’s this type of investigation that companies who are successfully minimizing variation do on a regular basis.

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.
