chapter 9: management of quality Flashcards
quality
the ability of a good or service to consistently meet or exceed customer expectations
quality control
monitoring, testing, and correcting quality problems after they occur
quality assurance
ensuring that a product’s quality will be good by preventing defects before they occur
when did the quality assurance thinking pull up?
in the 1950s
management system (QMS)
a structured and documented management system
it describes the policy, responsibilities, and implementation plan for ensuring quality
when did the quality management system (QMS) pull up?
who created it
In the 1970s
NASA and the Pillsbury company
total quality management (TQM)
approach places greater emphasis on customer satisfaction
involves all levels of management and workers in a continuing effort to increase quality
continuous improvement
continuous improvement
Never-ending improvements to key processes as part of total quality management
when did the total quality management (TQM) pull up?
1980s
The aspects or dimensions of quality of goods
Performance
aesthetics
special features
conformance
reliability
durability
perceived quality
service after sale
the term “fitness for use”
used to define quality
–> quality is whatever the customer requires in his/her particular use of the product
the dimensions of quality of services
tangibles
convenience
reliability
responsiveness
timeliness
assurance
courtesy/empathy
when is product’s quality determined?
- Product design
- Production process design
- Production
- Use
Product design
he characteristics and specification of a product such as size, shape, and material
Conformance to design specification during production
refers to the degree to which the produced good or service is defect-free
degree to which it complies with the specification of the designer
Cost of quality
determines the resources used:
to prevent poor quality
appraise the quality of the products
deal with internal and external failures
four categories of cost of quality?
internal failure costs
external failure costs
appraisal (detection) costs
prevention costs
Internal failure costs
part or product failures discovered during production
external failure costs
to part or product failures discovered after delivery to the customer
appraisal (detection) costs
inspection, testing, and other activities intended to uncover defective products
Prevention costs
attempts to prevent defects from occurring
which costs of quality categories are related to poor quality?
Internal and external failure costs
which costs of quality categories are investments to achieve better quality?
some appraisal (detection) costs
prevention costs
Taguchi quality loss function
The quality worsens as measurement deviates from the target
the quality loss increases at a faster rate the farther the measurement is from the target
it implies that quality keeps improving the better and more accurate the production process becomes
