Process capability

The literature on quality defines process capability as a metric that compares the variability of its output with tolerances. There are, in fact, two different concepts:

The ability of a process under nominal conditions to consistently produce output that meets expectations.
The means of assessing it.

Of Bubbles and Arrows

[The featured image is an ISOTYPE from Marie Neurath (1936)]

Maps of symbols connected by lines are the most common form of graphic communication about operations, next to bar charts, pie charts, and time series. The symbols may be a variety of pictograms and there may be different types of lines, including arrows, double-headed arrows with a variety of arrowheads, with dashed lines of varying thicknesses…

This is about what you can do with such maps beyond communicating, and the challenges of mapping systems that don’t fit on one slide. It is also about improving current practices.

Deep Learning And Profound Knowledge

[The featured image is Maureen Mace’s Tree of Knowledge]

In the news, Deep Learning is the currently emblematic technology of Machine-Learning (ML) and Artificial Intelligence (AI). In Management, the System of Profound Knowledge (SoPK) is a framework by W. Edwards Deming that specifies what individuals should know to be effective leaders of business organizations.

Your knowledge is what you have learned. You would not call a deep lake profound but a deep thought is also profound and vice versa. When discussing abstractions, there is no daylight in meaning between deep and profound.

Consequently, we might expect Deep Learning to be the process by which you acquire Profound Knowledge but it is nothing of the kind. As technical terms, they are unrelated and neither one matches expectations based on common, everyday usage.

QRQC at Valeo | Rob van Stekelenborg

“Recently, Michel Baudin […] invited practitioners to further contribute to the knowledge on QRQC, among which myself. As I feel a brief answer on LinkedIn would not do justice to the richness of QRQC, I decided to dedicate a post to the topic. Without ambition, however, to try and be complete in this post, which I feel is not possible with a vast topic like QRQC. But let’s dive in and share some of my experiences with and views on QRQC, the way I experienced and lived it at Valeo at the time.”

Michel Baudin‘s comments: Thanks to Rob van Stekelenborg for stepping up and sharing all of these details.

Nissan’s Quick Response Quality Control (QRQC)

Nissan’s Quick Response Quality Control (QRQC) is a management approach. It’s about organizing the response to quality problems, not about the technical tools used to solve them. It is intended to help detect problems, solve them, and document solutions, thereby growing the skills of the workforce. QRQC neither mandates nor excludes mistake-proofing or any statistical/data science tool.

This is meant to introduce QRQC to those who have not heard of it but it is also a call for practitioners to correct any misperceptions, add details, or share their experience.

More About VSMs From Jeffrey Liker

Thanks to Jeffrey Liker for providing additional details on the transformation of this tool. Initially, Toyota used it occasionally with suppliers. The Lean Enterprise Institute (LEI) turned it into the Value Stream Maps (VSM) that it has promoted as foundational to Lean.
