COSTS
OF QUALITY AND RETURN ON
QUALITY
The
Cost of Quality:
It's
a term that's widely used and
widely misunderstood.The "cost of
quality" isn't the price
of
creating
a quality product or service. It's the
cost of NOT creating a
quality product or
service.Every
time
work is redone, the cost of quality
increases. Obvious examples
include:
·
The
reworking of a manufactured item.
·
The
retesting of an assembly.
·
The
rebuilding of a tool.
·
The
correction of a bank
statement.
·
The
reworking of a service, such as the
reprocessing of a loan operation or the
replacement of a
food
order in a restaurant.
In
short, any cost that would
not have been expended if quality were
perfect contributes to the cost
of
quality.

Total
Non Quality Costs and
Return on Quality:
The
sum of the above costs to produce a
product or to deliver a service. This
represents the difference
between
the actual cost of a product or service and
what the reduced cost would
be if there were no
possibility
of substandard service, failure of products or
defects in their manufacture. The
measure of
revenue
saved by producing the right
product the first time and
every time will actually be
the return
one
gets by implementing the system of
quality.
In
general if preventive system costs
Rs. 1 like any QA system
then QC overheads are RS 10
in
comparison.
The costs incurred on
failure is Rs 100 and even sometime
higher (1000 or more) as
you
may
totally loose your customers,
your rapport or your total
market.
Hence
we need to learn that
quality system is an investment
which ultimately reduces the
total cost of
production
or working as we have to consider every
effort of ours financially accountable to
make
quality
a business case.
Quality
is a continuous journey and
hence not a
destination.
