Abstract
Good design enables a company, however large or small, to
compete profitably in world markets with quality products at
competitive costs.
In the past, the term quality has been largely interpreted to
mean luxury or elite, especially from a customer or market point of
view. Quality does, in reality, have a much broader definition. In
manufacturing, quality is commonly considered as a down-line
"measurement" term or goal, even though experts believe
that practically all of a products cost and quality are committed
by decisions taken during the design and planning stages.
Quality is also influenced by the management and organization of
these disciplines: the adoption of quality standards such as
ISO9000 is only a first step in the realization of quality
products.
There is no doubt that in recent years consumer expectations
have increased with regard to produce reliability and quality.
Manufacturers have also realized that not only can an unreliable
product lead to crippling warranty cost, but the loss of reputation
can severely effect future business. Therefore, building in product
quality and reliability at the design stage is essential for
continued success.
There exists an important need for techniques in design for
quality (DFQ) and design for reliability (DFR) which will aid
design and support the product introduction process. At the moment
there are too few methods in DFQ/DFR and none have been taken up
widely.
