The origin and development of the introduced methodology is partly due
to special circumstances of history. Burdened by the conditions in the 1940s and
50s, methods for practical problem solutions with relatively fast results were in
demand. Further years passed until a solid methodical framework was available,
which, however, was not easy to communicate. One of the main reasons for this
was publications in the Japanese language, which only became accessible in
translations in the proper sense at a later point in time. Ultimately, the method’s
persuasiveness was based on the low effort to obtain reliable results. Today, the
consequent application of this method has found its way not only in manufacturing
but into many other areas, such as biotechnology and diagnostics, to name a few,
with even more opportunities any time.
