…WHAT IS QUALITY
The Quality Gurus – Edward Deming
Quality is
“uniformity
and
dependability”
Focus on SPC
and statistical
tools
1986
“14 Points” for
management
PDCA method
1900-1993
The Quality Gurus – Joseph Juran
Quality is
“fitness for
use”
Pareto
Principle
Cost of
Quality
1951
General
management
approach as
well as
statistics
1904 - 2008
• ISO 9000:2005:
Is the degree to which a set of inherent
CHARACTERISTICS fulfills REQUIREMENTS
NOTE:
1. The term quality can be used with adjectives such as
poor, good or excellent.
2. Inherent, as opposed to assigned, means existing in something,
especially as a permanent characteristic.
QUALITY IS ….
• Defined by the customers
• Must be measurable; if you can measure it
you can maintain & improve it
• Relative
• Cannot be inspected into our products. It
must be in-built into the product
• Means do it right first time
• Requirements can come from the customer or
you but agreed to by the customer
…… QUALITY IS A MOVING TARGET DRIVEN BY THE CUSTOMER
…… Where we want to be
Quality is…..
Invisible when GOOD
Impossible to ignore when BAD
Dynamics Of Quality And
Standards
• Both quality and Standards which defines the
former are dynamically aligned with the global
quality game for fair and healthy trade
• Standards helps in the determination of Quality
• Without Standards, quality cannot be controlled
nor assured!
• Standards help in establishing the consistency
and reliability of quality otherwise known as
quality control and quality assurance
Why are Standards
important?...competitive tools!
 Continual quality awareness creation
 Conscientious implementation of Standards
enables
 Implementation of quality control, quality
assurance and formal quality management system
 Provision of objective evidence of product
performance as expected by…standards
These are the competitive tools which guarantee
market share and are strategic for sustainable
economic growth
Standards are generally…
 Democratic.
 Voluntary
 Can be used to regulate or legislate.
 Market-driven
 Consensus
 Standards usually represent the state of the art.
 Globally relevant
 Standards are technical agreements which provide
the framework for compatible technology
worldwide. They are designed to be globally
relevant - useful everywhere in the world.
WHAT IS QUALITY MANAGEMENT
SYSTEM ?
 Quality Control:
• Operational techniques and activities used to fulfill requirements for quality
 Quality Assurance:
• Planned and systematic activities to provide adequate confidence that
requirements for quality will be met
 Quality Management System:
• Organizational structure, resources, processes and procedures needed to
implement quality management
• Thus quality control ensures consistency, Assurance guarantees reliability of the
controls and a structured formal system ensures quality is total
Quality Control
• The process of monitoring specific project results to determine
if they comply with relevant quality standards and identifying
ways to eliminate causes of unsatisfactory performance.
• Input includes: work results, Quality Management Plan,
operational definitions, and checklists.
• Methods used include: inspection, control charts, Pareto
diagrams, statistical sampling, flowcharting, and trend
analysis.
• Output includes: quality improvements, acceptance decisions,
rework, completed checklists, and process adjustments
Quality Control
• Quality control is a set of “activities” that need
to be performed in order to detect problems
during production and before the product
goes live.
• These activities ensure that final deliverable
meets the specifications and quality standards
set by the organization.
• QC often includes peer reviews, “testing”,
code reviews etc.
Quality Control
• In theory, quality control can be achieved with
minimal testing.
• For example, a thorough review of source code
and checks for known previously problems can
reduce the possibility of defects and might be
enough to meet the quality standards set by the
organization.
• However in most cases, testing is the most
important activity for quality control, but it is
not the ‘only’ activity.
Quality Assurance
• The process of evaluating overall project
performance on a regular basis to provide
confidence that the project will satisfy the
relevant quality standards.
• Input includes: Quality Management Plan,
results of quality control measurements, and
operational definitions.
• Methods used: quality planning tools and
techniques and quality audits.
• Output includes: quality improvement.
What is Quality Assurance?
• Quality Assurance (QA) is a process driven approach, it is
a process to monitor and improve existing quality
processes.
• It is a process of verifying whether the product or
services meets or exceeds the customer expectations.
• It ensures that the product or services are developed or
implemented on agreed standards.
• Quality assurance ensures that the processes designed
for the product development and services are effective
enough to meet the objectives.
• It prevents defects/errors.
Quality Assurance
• Quality assurance is about engineering
“processes "that assure quality
• The keyword to pay attention to is
“processes”.
Processes need to be:
–
–
–
–
–
–
Defined
Measured
Compared to a standard
Evaluated
Take corrective action on
Evaluate corrective action taken
Quality Assurance
• Defects occur because something somewhere did
not happen the way it needed to.
• Testing might help in detecting those defects, but
not in avoiding them.
• A defect once fixed cannot ensure that it won’t occur
again, even if the root cause is found. The process or
the system that allowed that defect to occur is what
needs to be re-engineered, and this is what is called
quality assurance.
Quality Assurance
• Everyone who is involved in the end to end
development process, including analysts,
developers, testers, managers etc., is an
important player in assuring quality.
• In fact, QA might not involve testing at all.
Quality Assurance
• If a company wanted to bring down its defects per
million ratios, would testing alone be able to help
achieve this goal?
• The answer is no, because in practice, not every
defect can be found and fixed.
• However, if the processes that go into developing a
product were reviewed and best practices were
implemented, the load on testing team is likely to
reduce.
W. Edwards Demming on Quality
• Quality is an attribute of a product or service that
can only be defined by the customer.
• Because of this its meaning is relative
• Quality or lack of it is one of the outcomes of the
specific business process that produces a product or
service
• Quality is produced by proper execution of such a
process
• The job of quality management is to provide the
system and the leadership to facilitate such proper
execution
• Quality is heavily reliant on Standards
Successful standards go unnoticed
 Successful standards usually go unnoticed
 The importance of standards is noticeable when
problems arise, e.g.
◦ Incompatible electrical plugs and sockets worldwide
◦ Baltimore fire 1904: Hoses of fire fighters from
neighbouring cities did not fit hydrants in Baltimore
 A lack of standards can lead from mere
frustration to needless deaths
24
Standards are everywhere!
e.g. ISO freight containers (ISO,1968)
Redefined Shipping and international trade!!!
25
Standards are everywhere!
e.g. McDonald’s Hamburgers
26
Standards are everywhere!
More examples …
• Units of measurement
• Length, width and thickness of credit and bank cards, as well
as the location of the magnetic strip on such cards, are
standardized, which allows the use of the cards in any
automatic card reader, not just the automatic teller machines
of one’s own bank.
• Layout of QWERTY computer keyboard
• Size of light bulb fitting
• Paper format (A0, A1…..; height-to-width ratio 1.4142 : 1)
• GSM protocol for mobile phones
• Vehicle safety test procedures
27
What is a standard?
Mostly used in two rough senses:
• it is an agreement developed by several parties with the intent
that all parties comply
• it is a product or service with a significant market share
There are many definitions. Most try to specify
the first type of standard (i.e. the agreement).
• Standards prescribe behavior or characteristics
of people or inanimate objects, often in
technical terms
Many definitions of standard
Definition depends on who is asked, e.g.
• Formal standards bodies: a standard is “a document
established by consensus and approved by a recognized
body, that provides, for common and repeated use, rules,
guidelines or characteristics for activities or their results,
aimed at the achievement of the optimum degree of order
in a given context” (ISO/IEC, 2004b, p.8)
• Industry: “A standard [can be] of any form or type (…). A
standard is also one of the agents used (…) to bring about
market change” (Cargill, 1989, p.41)
29
Why are standards important?
Standards contain information
“We live in a world profoundly reliant on product standards”
(WTO, 2005, p. XXIV)
Standards contain Information. They
–
–
–
–
–
–
–
–
Indicate product safety
Clarify health risks
Clarify environmental risks
Increase transparency in the market (consumer and producer
expectations)
Create a level playing field
Reduce information search costs
Reduce production costs (allows economy of scale in production)
Necessary for diffusion of new technologies
30
Standards ensure products safety
• A consumer buying a gas stove, for instance,
might want to know whether it complies with
a standard that specifies how the oven must
be designed to ensure that heating the oven
will not cause parts to expand and cause a gas
leak and explosion!
3
Why are standards important?
Standards create compatibility
Compatibility defined as
• ‘the suitability of products, processes or services for use
together under specific conditions to fulfill relevant
requirements without causing unacceptable interactions.’
(ISO/IEC, 1991)
• Two types of compatibility between components (David &
Bunn, 1988)
• compatible complements (e.g. plug and socket)
• compatible substitutes (e.g. plug A and B in respect to
socket)
32
Why are standards important?
Standards create compatibility (cont..)
• Standards create Compatibility
– Networked environments* like telephone
communication and broadcasting require
standards
– Standards coordinate technology (Schmidt &
Werle, 1998)
– Standards coordinate markets, e.g. availability
of complementary products
– Standards facilitate international trade
33
Causes for the increasing importance of
standards
• Expansion of global markets
• Increasing anonymity of markets (standard-compliance
raises trust)
• Increasing concern for safety, health and
environmental issues
• Growing quality consciousness (higher demand for
quality standards)
• Use of standards to protect against mistakes > legal
accountability
• Regulation which encourages the use of standards
34
Why participate in making standards?
Industry
• Why do companies participate? (Cargill, 1989)
– A standard is a change agent, a strategic tool to influence the
market
– Participate if a proposed standard affects their business,
responds to a problem, focuses on their market need
– Standardization is an effort to guide momentum in the
market (p. 69)
• Creating a standard is a form of collective consensual
leadership, leadership by conviction
– Standard is a guidepost that points towards the future of a
market.
• It provides predictability to business (p. 48)
• It provides constancy to user operation (p. 70)
35
Why participate in making standards?
Consumers
Why do consumer organizations participate?
(WTO, 2005, p. XXVII):
• Standards are important for consumer goods like food,
drugs, vehicles, electrical appliances, safety equipment
• Standard requirements regarding design (toys),
ingredients (paint), process of manufacture or
production (meat), performance (helmets)
Why participate in making standards?
Consumers (cont..)
“Consumers expect that services and products will be consistent in
quality, durability and ease of use. International Standards are
voluntary rules and guidelines that help to ensure:
• safer, healthier, more environmentally sound products and
services;
• products with improved quality and reliability;
• better operational compatibility between products and greater
consistency in the delivery of services;
• improved choice and access to goods and services;
• lower costs for consumers;
• better product or service information.” (ISO/IEC, 2003)
37
Why participate in making standards?
Government
Governments need standards for
• Regulation (e.g. minimum standards for
consumer protection)
• Economic growth
– Information and compatibility
– Education on standardization is part of the national
economic strategy (e.g. Asian countries)
38
Why NOT participate in standards
making?
Who does not want standards
• Those with a stake in the status quo (e.g.
company with a large market share in the
area of standardization)
• These parties sometimes participate in order to
frustrate the standards process
39
Many kinds of standards
•
•
•
•
•
•
Terminology standards
Safety standards
Health standards
Procedural standards
Compatibility standards
Etc.
40
When does standardization take place?
Anticipatory – Responsive standardization
• Anticipatory standardization
o standardize before technology has been developed and
marketed
• Enabling standardization
o Parallel standards and market development
• Responsive standardization
o standardize technology variety available on the market
