The 2012 paper in Science about the CRISPR/Cas9 system has been hailed as the greatest breakthrough in biology since Crick and Watson’s discovery of the DNA double helix in 1953. It has earned its two Principal Investigators (PI), Emmanuelle Charpentier and Jennifer Doudna, the 2020 Nobel prize in chemistry. Laypersons cannot really follow this paper but what we can better understand is how the research team worked. And it is remarkable.

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.

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.

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.

Costs are the object of heated arguments when working to improve manufacturing operations, with participants assuming that the notion of cost itself is self-evident while, in fact, they understand it differently and talk past each other. This is an attempt to bring some clarity to the subject.
