has become an important business strategy for many organizations; manufacturers, distributors, transportation companies, financial services organizations, healthcare providers, and government agencies.”
Controlling and improving quality
Will the product or service to the intended job?
Performance
What does product do/ service give?
Features
How often does the product/service fail?
Reliability
Is the product/service made the exactly as designer standard intended?
Conformance
How long does the product or service last?
Durability
How easy to repair the product or to solve the problems in the service?
Serviceability
What does the product service look like, to smell, sound, and feel like?
Aesthetics
What is the reputation of the company or its products or services?
Perceived Quality
- Variations in grades or levels of quality or intentional, and consequently, the appropriate technical.
Quality of Design
are the lack of consistency between production outputs.
Variations
- This is how well the product conforms to the specifications required by the design.
Quality of Conformance
the extent to which these procedures are followed, and the motivation of the workforce to achieve quality.
Quality of Conformance
- It is the reduction of variability in process and products.
Quality Improvement
the reduction of waste.
- Quality Improvement
Is the set of operational, managerial, and engineering activities that a company uses to ensure that the quality characteristics of a product are at the nominal or required levels and that the variability around his desired levels is minimum.
Quality Engineering
number of elements that jointly describes what the user or consumers thinks of pass quality please parameters
Quality Characteristics
Quality Characteristics, sometimes these are called the
CTQ critical-to-quality
Quality characteristics types
physical
sensory
time-orientation
length, weight, voltage, viscosity
physical
taste, appearance, color
sensory
reliability, durability, serviceability
o Time Orientation
classification of data
Attributes (discreet) data
Variables (continuous) data
measurements such as length, voltage or viscosity.
Variables data
data often taking in the form of count.
Attributes data
are often evaluated relative to specifications.
Quality characteristics
It is the value of a measurement that corresponds to the desired of value for the quality characteristics.
Nominal or target value
Largest allowable value for equality characteristics.
Upper Specification Limit (USL)
Smallest allowable value for a quality characteristic.
- Lower Specification Limits (LSL)
Are those that failed to meet one or more of its specifications
Non-conforming products
specific type of failure
non conformity
need for more consistent products that are mass-produced and needed to be interchangeable.
Industrial Revolution (18th century)
perfected scientific shortcuts for shifting through mountains of data to spot key cause-effect relationships to speed up development of crop growing method.
RA Fisher
transformed Fisher’s methods into quality control disciplines for factories
W.A. Shewhart
The Japanese Union of Scientists and Engineers (JUSE) established ______ in 1951
“Deming Price”
Is an industry-standard methodology for measuring and controlling quality during the manufacturing process
Statistical Process Control
are determined by the capability of the process
Control Limits
are determined by the client’s needs.
Specification Limits
is a systematic method to determine the relationship between factors affecting a process and the output of that process.
Design of Experiments (DOE)
it is used to find cause-and-effect relationships.
DOE
is an approach to systematically varying the controllable input factors in the process and determining the effect these factors have on the output product parameters.
designed experiment
defined as the inspection and classification of a sample of units selected at random from a larger batch or lot and the ultimate decision about disposition of the lot, usually it occurs at two points: incoming raw materials or components, or final production.
acceptance sampling
Is a strategic activity, and it is just as vital to an organization’s long-term business success as the product development plan, the financial plan, the marketing plan, and plans for the utilization of human resources.
Quality Planning
Involves identifying customers, both external and those that operate internal to the business, and identifying their needs.
Quality Planning
Is the set of activities that ensures the quality levels of products and services are properly maintained and that supplier and customer quality issues are properly resolved.
Quality Assurance
Involve the set of activities used to ensure that the products and services meet requirements and are improved on a continuous basis.
Quality Control and Improvement
acknowledges that defects are present but does not add value to the product
- Routine inspection
is unreliable costly and ineffective
Mass Inspection
focuses heavily on a system’s view of the supply chain with the objective of minimizing total supply chain costs and developing stronger partnerships with suppliers
- Supply Chain Management
simply overseeing and directing work
Supervision
providing guidance to help employees to their jobs with less effort
Leadership
encourages short-term thinking
