產品壽命週期內三角形互動關係 Edward William Barankin

某次Deming看了一位朋友寫的論文"概率與東方"*

內有一詩，趕緊記下來，戴明在《轉危為安》轉引了這一首日本古詩。

Kane ga naru ka ya
Shumoku ga naru ka
Kane to shumoku no ai ga naru

Is the bell that ring，
Is it the hammer that ring，
Or is it the meeting of the two that ring？


「鐘鳴乎？撞木鳴乎？鐘與撞木齊（諧）鳴乎？」

它比喻產（製造之聲）銷（顧客之聲）一體，才是品質正道。戴明用它來喻「銷－產關係」，更引發出整個產品壽命週期內三角形互動關係（《轉危為安》p.204）。

*這首詩在1982年版的第一字Kane 寫錯成 Kano，原引論文為 Edward William Barankin, 1920-1985 ，是柏克萊大學 (Berkeley) 的統計教授。他的同事這樣簡介他：

Ed Barankin died on May 1, 1985, after an illness of several months.
He was born in Philadelphia in 1920 and received the A.B. at Princeton
in 1941. Except for the year 1946-47, which he spent at the Institute
for Advanced Study as Hermann Weyl's assistant, he was associated with
the University of California, Berkeley, continuously from 1941; as a
graduate student in mathematics 1941-46, as a member of the
mathematics faculty 1947-55, and as a member of the statistics faculty
1955-85.

His early work in the theory of sufficient statistics was highly
regarded at the time, and is still cited. About 1950 he started
developing a new, rather complicated theory of stochastic processes
and behavior and, although he continued to do excellent work in other
areas, including sufficient statistics and programming in operations
research, his dominant research interest for the rest of his life was
his process theory. In his theory, as in the theories of Keynes,
Carnap, and Jeffreys, when the relationships among events are
adequately described, the probabilities of the events can be
calculated from their descriptions. Most of his United States
colleagues never really understood his approach to stochastic
processes, but his work was highly regarded in Japan, and was
published in several Japanese statistical journals. Indeed, in
recognition of his work he was appointed Honorary Member of the
Institute of Statistical Mathematics, Tokyo, in 1975. His process
theory was also highly regarded by colleagues at the University of
Mexico, where he spent several periods as visiting professor at the
Institute of Mathematics.

Ed was among the first of the UC faculty to show a strong interest in
helping the predominantly black colleges in the South. In 1964, he
organized the Special Committee on Visiting Lecturers to Negro
Colleges and Universities (in 1968 the name changed to Special
Committee for Development of Communication with Negro Colleges and
Universities). Under committee sponsorship, he gave a number of
lectures at Morehouse, Talladega, and other predominantly black
colleges. Some of the links he established between UC and
predominantly black colleges are still in place.
