In the 1950s, Eizaburo Nishibori, a member of JUSE, and Sigeiti Moriguti of Tokyo University invited W. Edwards Deming to lecture on statistical methods for business in a session sponsored by the Keidanren, the most prestigious society of Japanese executives, under the leadership of its chairman, Ichiro Ishikawa (also president of JUSE).

IATF 16949:2016 clause 7.1.5.1.1 requires measurement systems analysis (MSA) to quantify gage and instrument variation. The deliverables of the generally accepted procedure are the repeatability or equipment variation, and the reproducibility or appraiser variation.
Health Apps Track Vital Stats, But Doctors Aren’t Using the Data
Health-tracking devices and apps are becoming part of everyday life.
Measurement Systems Analysis for Attributes, Part 2
The first part of this series introduced measurement systems analysis for attribute data, or attribute agreement analysis.
MSA: Back to the Basics
When we talk about measurement system analysis (MSA), people tend to focus on attribute agreement analysis because it is usually quicker and easier to do than a gauge repeatability and reproducibility (gauge R&R) study.
Measurement Systems Analysis for Attributes, Part 1
Measurement systems analysis (MSA) for attributes, or attribute agreement analysis, is a lot like eating broccoli or Brussels sprouts. We must often do things we don't like because they are necessary or good for us.
Workloads of Counting Queries: Enabling Rich Statistical Analyses With Differential Privacy
To date, this series focused on relatively simple data analyses, such as learning one summary statistic about our data at a time.
