In today’s column, I will be looking at process validation and the problem of induction. Yesterday, I looked at process validation through another philosophical angle by using the lesson of the Ship of Theseus.
The U.S. Food and Drug Administration (FDA) defines process validation as “the…

The one complaint—the one problem—that nearly every company puts at (or very near) the top of its list of challenges is communication. George Bernard Shaw, the famous Irish playwright, sets us straight on this when he said: “The single biggest problem in communication is the illusion that it has…

The June 30, 2017, episode of QDL offered a wrinkle in time, of sorts: not only orbiting debris and medieval medicine, but moments in the here and now such as our interview with Keith Bevan of the Coordinate Metrology Society and the UK’s National Physical Laboratory, and an on-the-go version of…

Before you can improve something, you must first have a very clear understanding of what its current state is. Don’t assume you know what it is. Go to the gemba, be it the factory floor, the shipping and receiving area, your office, or even take a minute to focus on yourself, and observe what is…

Plant-floor quality issues tend to focus on a company’s technical resources. When products fall out of spec, alarms sound and all hands are immediately on deck to fix things. Despite large technology investments to monitor and adjust production processes, manufacturers are still bedeviled by…

To meet the 2018 deadline for becoming certified to ISO 9001:2015, organizations are scrambling to overhaul their quality management systems. One major revision to ISO 9001 is the requirement to identify, evaluate, and address risks. Unfortunately, a tool most appropriate for these actions has…

Many of us are familiar with the concept of the Ohno Circle, innovated by Taiichi Ohno at Toyota during the 1940s. While familiarity with the technique and the goals it sets to accomplish is one thing, how many of us have actually participated? The surprising answer is… probably all of us, in a…

Lean thinking has taken its rightful place in the effort to improve efficiency in manufacturing. However, it isn’t fulfilling its potential in many areas, most notably with knowledge workers. This is due to a fundamental flaw in how lean is presented and utilized. With a better constructed…

In part one of “New Spin on the ‘Stand in a Circle’ Exercise,” I described how Taiichi Ohno, the creator of the Toyota Production System, used the “Stand in a Circle” exercise to help managers identify waste in their operations.
During this exercise Ohno would take a manager or student…

Building airplanes and spaceships poses some of the most unique engineering and manufacturing challenges mankind has ever encountered. Fortunately, you don’t have to build rockets to benefit from rocket science. Manufacturers of most any product can improve their efficiency and…

During the mid-1940s, Taiichi Ohno established the Toyota Production System, which is primarily based on eliminating nonvalue-added waste. He discovered that by reducing waste and inventory levels, problems get exposed and that forces employees to address these problems. To engage the workers and…

You can be known as a hard worker and counted on to tie up loose ends, but fall behind when co-workers’ tasks are on hold until yours are complete, and you’re perceived as needing an attitude adjustment. What would you want to do? Place blame or work on a remedy? There is a solution: Personal…

There are those days where your personal kanban is on fire. You’re in a state of flow and tickets are just moving right along. The days go by and you look at your “done” column… it’s full. Really, really full.
The “done” tickets seem to swim. There are so many of them! You’ve been productive, but…

Reading the Automotive Industry Action Group’s CQI-8 Layered Process Audit (LPA) Guideline, you might notice a line saying LPAs are “completed on site ‘where the work is done.’”
For lean manufacturing experts, this specific quote might bring to mind gemba walks, a method where leaders observe and…

A few months ago I told you how my wife and I had found a midcentury remodel project only a couple blocks away from where we currently live. We wanted to create a “lean home”—smaller with a simple layout, less storage space, and as few walls and doors as possible to optimize flow. The remodel has…

For me, Taiichi Ohno and Shigeo Shingo are a bit like the Lennon and McCartney of waste elimination. Together they frame the technical and social sciences of what we call lean today.
Taiichi Ohno tells us there are seven wastes that account for 95 percent of the elapsed time between “paying and…

Founded in 1927 to produce aluminum splints—cutting edge at the time—Zimmer Biomet is a medical device company commanding second place in the entire world’s overall orthopedic market share. The organization’s stated purpose is to “Restore mobility, alleviate pain, and improve the…

My eye was caught recently by a gossipy article concerning NASA’s suit situation. Spacesuits, that is, not the standard-issue coat and trousers worn by many earthbound employees at the agency. It seems its Office of Inspector General (OIG) issued a thumbs down following a spacesuit audit, warning…

There is an enemy in your company, and it’s invisible. You can’t see it because it literally is not there. Yet its impact is massive on every level of the enterprise, from boardroom to marketing to operations to the field staff. And the only way we have even the smallest chance of destroying it is…

The American economy is underpinned by networks. Road networks carry traffic and freight; the internet and telecommunications networks carry our voices and digital information; the electricity grid is a network carrying energy; financial networks transfer money from bank accounts to merchants.…

I have been reading a lot these days about Western philosophy. The most recent book, All Life is Problem Solving (Routledge, 2001), is by Karl Popper, one of the great philosophers of the 20th century. This is a collection of Popper’s writings. One of the great teachings from Popper is the concept…

In 1996, former Microsoft employees Gabe Newell and Mike Harrington formed Washington-based video-game development studio Valve Corp. Two years later, they released a PC game called Half-Life to universal critical acclaim; it was a watershed moment in gaming history, and nearly 20 years later the…

In last week’s Quality Digest Live: design digital assistance instead of digital assistants, how to make better beer, and closed-loop manufacturing.

To improve the workplace, maybe we need a fewer digital assistants and lot more…

Mindful observation takes effort and practice, but it’s valuable if you want to be a leader. It allows you to watch processes in action and look for small nuances and opportunities for improvement. For example, the wait staff at top-tier hotels do this every day. One waiter is always watching,…
