ISO 9000- characteristics fulfills the requirements, i.e. needs or
expectations that are stated, generally implied or obligatory.
The qualityof a product is its ability to satisfy, or preferably exceed, the
needs and expectations of the customers.
Garvins five perspectives of quality
1) Transcendent: quality is identified when experienced!cannot be
defined exactly
2) Product-based view: quality is measurable->precise characteristics the
user cant judge3) User-based *more Deming: quality is judged by customers!needs and
expectations fulfillment
Swartsboth based
4) Manufacturing-based *more Crosby
5) Value-based: cost/price relation!"different approaches are needed in
different parts of organization
Needs and expectations
We dont expect them to be fulfilled often we dont realize owr ownneeds (personal needs; social needs)
Includes elements that we dont need
1.1.2. Costumer concept

-find who
-find out needs and expectations
-fulfill/exceed needs or expectations

!quality dimensions for goods
Quality dimensions of an article Quality dimensions of a service
1) Reliability (how often problems occur)
2) Performance (speed, capacity, size)
3)
Maintainability (how easy to findproblem)
4) Environmental impact (effect onenvironment (pollution))
5) Appearance (astatic, design)
6) Flawlessness
7) Safety
8) Durability (used, phased, transported
without breaking)
1) Reliability (punctuality, doing what you
promised)
2)
Credibility (trust of the supplier)3) Access (contact the supplier website
availability, etc.)4) Communication (understand each other)
5) Responsiveness (willingness to help cost)
6) Courtesy (supplier behavior, politeness,
kindness)
7) Empathy (understand cost, situation)
8) Tangibles (physical environment of wher
the service is given)Quality dimensions for services:
Services vs goods:
-not tangible hard to specify and measure
-customer is active in creating the service
-consumed while learning created
-customer is not owner after delivery-cannot be tested or tried before
moment of truth - meeting between suppliers (customer!not turning
back)
Commercial experiences!attractions parks!memorable!high
costumer value
Note: importance of each dimensions depends of the product
Each product/service meet its own costumer requirements

You always focus on the customer- the ideal. Customers always want a good service.It doesn't always happen, that.s what we expire
The customer is the one who said: yes it is good/no, it's bad You need to focus on
processes.
1. focus on processes: The highest process is cash to cash. Any business stars with
cash: they get customers, they sell smth and then get cash We need to look how do.
Advertise, recruit new customers, answers and so on, all of those processes.
2. Improve continuously: never have the place to say: we did everything, we aredone. There is always an opportunity to be better. Car industry: The quality of cars
changed a lot, this is a feature-part of the quality. Suspension has been gone; safety
etc.
3. Base decisions on facts: They are still a lot of managers who make decisions. All
decisions has to be based on facts
4. Let everybody be committed: If all employees are involved-quality organization.(Cazy method)Committed leadership- you need to have leaders who are really belief, not only
taking the money.
The Quality Chains(pic.2)
Most of the people in the company don't deal with the customers. We only
have the sales team who contact with customers. But you still need
everybody to be concerned with the customer.
External customers/suppliers - a sells to company b and they supply company c.Company a still has to care about company c to fulfill their needs and ensure quality

Aristotles 3 models of persuasion that need to be fulfilled if you are to be convincing
ethos, logos, pathoso
Ethosrefers to the character of the speaker.o
Pathosis about evoking feelings in your listener by mental pictures which give
associations to the listener. The emotional or motivational appeals; vivid language;o
Logos:the speech, rational. the logic used to support a claim (induction and
deduction); can also be the facts and statistics used to help support the argument). [It
deals with what words are used and how these words are put together into sentences,
building chains with logical contexts and plausible arguments.]
Communication happens when you have all of these.

5-Improve constantly and forever the system of production and service, to improve
quality and productivity, and thus constantly decrease costs. improve continuously
and forever- youre never done! Lower cost of operation is everything we do.
7-Adopt and institute leadership. The leaders should focus on the process and help
people to do a better job. Leadership is required not supervision.8 Drive out fear so that everyone may work effectively for the company. peopleneed to feel secure, confident. Employees should not be afraid of saying that
something is wrong in the company.
9-Breack down barriers between departments, build a system. People from different
areas as research, design, sales, technology and production should work as a team to
foresee a production problems and potential product or service issues. Everybody
wins if the system wins.
13-Institute a vigorous program of education and encourage self improvement for
everyone. Organizations need employees who constantly go on developing,improving and broadening their knowledge. Management should support, initiate and
stimulate education and personal development.

Demings profound knowledge
Profound knowledge is based on the four elements:
Appreciation for a system (system thinking) without an aim there is no system.
The management must know the system. System a network of interdependent
components trying to fulfill an aim. For ex. - orchestra
Knowledge about variation: the range and causes of variation in quality, and use
of statistical sampling in measurements;
Theory of knowledge: Deming emphasizes that management is largely a matter of
prediction. We must understand what will be the consequence of different actions
(have to predict). Information doesnt constitute knowledge without a theory (for ex.
English dictionary). The concepts explaining knowledge and the limits of what can
be known.
Psychology: concepts of human nature. We need it to understand what motivates
people and to understand the interaction between people; their behavior and realize
how people learn
Senges Learning Organization.
We need to look at the company as a system. Everything connected it each other. We
have to question all assumptions.
Personal mastery:personal growth and learning. Pm is a matter of knowledge and
skills
Mental model:driving. Autopilot because we know how the traffic works for
example. Its part of your mental model.
It means we are in the world

We have to ask ourselves why am I thinking what Im seeing. The way we look at the
world influences how do we see our company/your problem.
Team learning: we need to assimilate the ability of learning together better. The
importance of dialogue and group discussion. For a team to learn, they must be in
sync and reach agreement.Shared visions: A learning organization's employees all share a common vision.Personal goals must be in sync with the goals and vision of the organization.
Systems thinking: Organizations are a system of interrelationships. To become
more successful we need to analyze these relationships and find the problems in
them. This will allow an organization to eliminate the obstacles to learning.
Advantage of learning organizations

Experimentation with new approachesLearning from own experience and past story
Learning from the experiences and best practices of others.

Kaplan &Norton introduced the balanced scorecards.The idea is to focus not just on short-term financial performance measures, but also
to control and follow up the business activities with more long-term performance.
Four perspectives:
1) the financial perspective
2) the external customer perspective (dealing with customer value and customer
satisfaction);
3) the internal business process perspective (focusing on efficiency in the
organizations processes but also on employee satisfaction);4) the innovation, learning and growth perspective (focusing on a long-term
perspective of the organizations development), which can be regarded as a measure
of efficiency.
19. Processes and process management
19.1. Processes
Process a network of activities that are repeated in time, whose objective is to
create value to external or internal customers.
A process has a first activity and a final activity, a customer (a principal), and a
supplier (an agent);
If consist of a network of activities, produces a value-adding result; and is repeated
time and again.Processes are often differentiated into the following three categories(egnell;rentzhog) :
1) main processes task to fulfill the needs of the external customers and to refine
the product provided by the organization. 1-3 main processes
2) support process-whose mission is to provide resources for the main processes.
The support processes have primarily internal customers.
3) management processin which the task is to make decisions on the targets and
strategies of the organization and to implement improvements in the otherorganizational processes. (primarily internal customers)

!identify the suppliers to the process!
!better chances of achieving a shared vision
!everything is not a process (confusion between the process and process
orientation concepts)
19.2.1. The process management methodology
Organize for improvement. Appoint process owners and a process
improvement team.
Understand the process.
Define the inter-faces and investigate who the customers and suppliers are.
Map the process
Observe the process. Establish control points and implement regular
measurements
Improve the process consciously. Use and analyze the feedback from themeasurements to improve the process.!a central factor is to holistic view of
the organization + improve in the process: quality (capability to satisfy the c
needs and expectations; efficiency )how well the process are utilizing the
resources in the organization to produce results; adaptability (how well the
process can be adapted to changed prerequisites)
#important step in productivity and quality simplification
In process management there are three important roles, namely:
process owner (responsible for the strategic decisions concerning the
process);
process manager (has the operative responsibility);
competence supplier (the role is to supply the processes and functions in
the organization with the competence that is needed and to dimension he
manning in relation to the demand for competence)
The role concept
Roles describe the competence, not connected to specific activities
The role is associated with authority and responsibility

19.4. Benchmarking
Camp (1989)-the search for best practices that will lead to superior
performance
Different types of benchmarking, depending on where the comparison
process is foundInternal benchmarking (comparing site to site, department to d, country to cwithin the organization)
Competitor bm (-//-our own performance to that of out direct competitors)
Functional bm (-//-ourselves against competitors, best organizations)
Generic bm (-//-ourselves against the best from all industry groups)
The benchmarking process according to Xerox: plan#[do] search,-> observe,-
> analyze,#[study] adapt,#improve
19.5. Process innovationThe choice between improving an existing process and creating a ompletely new
one must be made by balancing the cost, the needs of improvement, and the risk
of failure.

23.1.Quality control circles and improvement teamsOne way to get all employees actively involved in improvement work is to form
small groups discussing different problems and come up with suggestions for
improvement. This activity is usually referred to as QC circles.
Using simple statistical tools, such as the seven improvement tools, people work
in QC circle discussing, analyzing and solving different problems, often aimed at
costs, safety, or productivity.-management must take an interest in the activities

Why do we need standards?
Standards ensure desirable characteristics of products and services such as:
Quality
Environmental friendliness
SafetyReliability
Efficiency and interchangeability
And at an economical costWhen products, systems, machinery and devices work well and safety, it is often
because they meet standards
When standards are absent, we soon notice. We care when products turn out to
be of poor quality, do not fit, are incompatible with equipment that we already
have, are unreliable or dangerous.
