Abstract
Managing quality has become the overall management function to
assure that customer requirements are identified and met with
satisfaction conforming to the requirements. Managers need to be
aware that quality is the responsibility of everyone in the company.
The quality inspector, unlike the traditional approach, is no longer a
policeman who is there to detect nonconformities or prevent defects.
Operators of the production floor are encouraged to monitor and
take corrective action whenever necessary on their own operation by
making use of statistical process control tools.
Effective implementation of a quality assurance system in a firm
requires use of appropriate statistical methods for monitoring
conformance to specification starting from the raw materials to the
final products. Traditional methods of analysis often provide delayed
identification of nonconformance occurrence, placing quality of
products at risk. The application of SPC techniques such as
Shewhart control charts allows continuous real-time assessment to
detect variations so that the process is maintained under a state of
statistical control, and improvement action taken to further reduce
variation.
