“Only through the collective efforts of their
individual members do companies change;
companies are incapable of changing
themselves.” -- V. Daniel
Hunt This question has been
debated for many years and varies considerably even with the quality experts (as
outlined in the comparison tables below). For certain, the experts agree,
the outcome affects all businesses today and will continue to do so in the
future.
(note: this comparison was
originally based on an article published in the "Quality" magazine, May
1992)
