(Q4-A) XYZ is a manufacturing firm that has suffered from
high levels of variation in the performance of some
production processes. The management of XYZ Identified
few assignable causes of these variations as they are
caused due to changes in working conditions, human
errors, lack of knowledge about quality, and differences
among materials.
Assume you are hired by XYZ to redesign quality and
product excellence. Develop an argument to explain
which of the two designs - design for excellence or
tolerance design - should be selected. Justify your
selection by arguing the advantages of the design you
select and the disadvantages of the design you discard.
