The zero-defect ideology represents the core functions or
features around which the entire aspect of quality management is
revolving. We can say that it emphasizes doing the process right
the first time rather than having to eliminate the factors that
cause the defect after output has been created. In order to
eliminate the wastes the business generates, there needs to be
proper consideration and support for avoiding potentially “costly”
mistakes or excessive time consumption, by creating a holistic
approach whereby there is a higher assurance to the specifications
and the requirements being met at the final stages with the initial
execution being brought within the specification and monitored
excessively throughout the chain in order to report any changes
that can be implemented to make the process more capable. There are
some major defects that can be established in the form of higher
output, higher customer satisfaction, customer loyalty, and better
sales and profits as a result. On the other hand, it can also incur
a very large cost investment in the initial phases in order to
ensure the process is conducted perfectly. We do, however, have to
consider the fact that through zero defects, the company does not
actually plan or fix the process to be perfect, rather, the output
has to be within the specified limits in order to be considered
acceptable and the process to be considered having zero defects,
this is what sets this ideology apart from other implementations
like lean and six sigma, whereby the processes are brought to the
best possible standards, which might be unnecessary or impractical
in some cases.
