Up until a few years ago, I wasn’t a big fan of run charts. Why not just go ahead and construct a process behavior chart and move on? Well, sometimes a run chart is more appropriate for certain data structures.
For example, some data are “chunky”—see Donald Wheeler’s treatment of chunky data in…

Provision 4.2 of ISO 9001:2015 cites “Needs and Expectations of Interested Parties.” Interested parties include not only obvious stakeholders (customers, suppliers, employees, and owners), but also anybody who is affected, or perceives himself as being affected, by the product or service.
Not all…

The word “kurtosis” sounds like a painful, festering disease of the gums. But the term actually describes the shape of a data distribution.
Frequently, you’ll see kurtosis defined as how sharply “peaked” the data are. The three main types of kurtosis are shown below.
Lepto means “thin” or “…
Quality Transformation With David Schwinn
Shortly after the death of the brilliant comedian and actor Robin Williams, his daughter Zelda quit Twitter and Instagram following online harassment over his death. How sad. We seem to somehow like to see the dark side of the world.
Even my three tennis buddies seem unable to keep from trash…

Employees want feedback that is meaningful and relevant to them, but often what they hear sounds like it’s been taken verbatim from one of those phrase books using stock comments like, “Mary is a team player and consistently thinks of others.”
That statement could apply to Mary, or it could apply…

Food and Drug Administration (FDA) medical device recalls are on the rise. An increasingly active FDA coupled with an increase of medical device software components is adding up to new challenges for manufacturers. It’s important to understand how the FDA uses IEC 62304, an international standard…

Connecting our information about customer desires with our designs is difficult. If it seems simple, we probably missed something. In the realm of product development, the most challenging and often the riskiest part of the design process is deciding precisely what features or functions our…

This is the fifth installment in our six-part series on how automating common business processes with enterprise quality management software (EQMS) can benefit your organization. In this installment, we’ll focus on the automated audit management process.
Manual systems often don’t provide the…

Along with an opposable thumb, we share one other trait with our hairy primate cousins: curiosity. We have an innate desire to understand “what happens if…” that begins in childhood. As we grow into adults, that natural curiosity dissipates, and we’re expected to have those answers (school, anyone…

In a previous article, I showed why there is no R-squared for nonlinear regression. Anyone who uses nonlinear regression will also notice that there are no P values for the predictor variables. What’s going on?
Just like there are good reasons not to calculate R-squared for nonlinear regression,…
Lean Math With Mark Hamel
Full-time equivalent(s), commonly referred to as FTE(s), represents the number of equivalent employees working full time. One full-time equivalent is equal to one employee working full time. Typically, FTEs are measured to one or two decimal points.
FTEs are not people. Rather, FTEs are a ratio…

Ihave worked with a number of CEOs during my many years of helping companies improve quality. Although all are different in their leadership styles, when it comes to their attitudes toward excellence, most top leaders fall into one of three categories.
The honeymoon CEO
The first is what I call…

Rachel was a new employee at a retail outlet. She was given the requisite week in the training room and then sent out to the sales floor. Part of her job was to restock merchandise that had been returned. She had been on the job but a few days when an item was returned in a damaged box. She…

I chatted about u-charts for rates last time, and this column was going to be about p-charts for percentage data. These are the two major charts for dealing with count data and are helpful for stratifying a stable section of process performance.
But something recently happened that saddens me and…

I recently read an article about a new dress code being imposed on Walmart employees (effective later this month). The purpose of the new dress code is to help customers more easily identify employees. I don't have a problem with that; given my recent experiences in a few different stores, more…

The regulatory landscape continues to change. One of the quality system approaches defined by regulators and the industry for mitigating risk is corrective and preventive action, better known as CAPA. Companies are often challenged by the CAPA process, which is one of the most important and…

A recent viewing of a Marx Brothers film caused me to reflect on one of the questions I’m frequently asked: “How do you deal with people who are against lean?”
My stock response is to quote Shigeo Shingo’s advice that “99 percent of objection is cautionary,” that is, people who appear to…

The adage that “You can’t teach an old dog new tricks” has been taken to task probably ever since it was first uttered. ThomasNet.com turned that whole idea on its ear with the newest round of upgrades to its website in 2014. In essence, instead of trying to teach old dogs (in this case seasoned…

Assuming there are still questions about the suitability of a gauge for a particular application after a gauge repeatability and reproducibility (GR&R) study, Measurement Systems Analysis, 4th Edition (MSA-4), published by AIAG in 2010, recommends using an additional study in the calibration…

Any leader or skilled improvement professional knows that metrics are necessary to define what success looks like, to measure progress toward a defined target, and to assess performance against defined standards. Metrics also serve as a powerful way to demonstrate improvement success to people who…

There are only two paths to lean leadership that people can take. One path, based on traditional human resource development models, nearly always results in failure. The second path nearly always results in success, but precious few leaders are willing to take this one.

Last month I was conducting a series of Boardwalks with a large company in Australia. The people in the company had an amazing array of kanban and other visual controls guiding their software development. Most important to me, they had achieved a culture not of continuous improvement, but of deep…

At the new NIST Center for Automotive Lightweighting (NCAL), workloads are fraught with stress and strain—all to help the auto industry take a heavy load off future cars and light trucks.
To meet proposed federal fuel-efficiency standards—54.5 miles per gallon by 2025, or nearly double today’s…

Leaders, especially superlative ones, are achievers. They get things done. Typically, they are hands-on, roll-up-the-sleeves types who attack life and its opportunities head on.
It's that sort of attitude, a tenacious, never-say-die pursuit of achievement, that contributes to success. Superlative…
