1.
Define Quality. Explain the need for improvement of Quality
Points (1+3)
The term "quality" has a relative meaning. This is expressed by the ISO definition: "The
totality of features and characteristics of a product or service that bear on its ability to
satisfy stated or implied needs". In simpler words, one can say that a product has good
quality when it "complies with the requirements specified by the client".
Most important definitions of quality are
Conformance to specifications measures how well the product or service meets the
targets and
dimensions of a machine part may be specified by its design engineers as 3 _ .05 inches.
This would mean that the target dimension is 3 inches but the dimensions can vary
between 2.95 and 3.05 inches. Similarly, the wait for hotel room service may be
specified as 20 minutes, but there may be an acceptable delay of an additional 10
minutes. Also, consider the amount of light delivered
by a 60 watt light bulb. If the bulb delivers 50 watts it does not conform to
specifications. As these examples illustrate, conformance to specification is directly
measurable, though it may not be directly related to the consumer’s idea of quality.
Fitness for use focuses on how well the product performs its intended function or use.
For example, a Mercedes Benz and a Jeep Cherokee both meet a fitness for use
definition if one considers transportation as the intended function. However, if the
definition becomes more specific and assumes that the intended use is for transportation
on mountain roads and carrying fishing gear, the Jeep Cherokee has a greater fitness
for use. You can also see that fitness for use is a user-based definition in that it is
intended to meet the needs of a specific user group.
2. Define cost of Quality
What are the components of Cost of Quality explain the optimal quality
(1+1+2)
The cost associated with the quality of a work product.
Cost of quality is the amount of money a business loses because its product or
service was not done right in the first place. From fixing a warped piece on the
assembly line to having to deal with a lawsuit because of a malfunctioning
machine or a badly performed service, businesses lose money every day due to
poor quality. For most businesses, this can run from 15 to 30 percent of their
total costs.
Cost of Quality (COQ )
1. Cost of Control (Conformance)


Prevention Cost
Appraisal Cost
2. Cost of not controlling (Non-conformance)


Internal Failure Cost
External Failure Cost
Four categories of costs contribute to an organization’s overall COQ:
1. Internal failure costs - costs associated with defects found before the
customer receives the product or service
2. External failure costs - costs associated with defects found after the
customer receives the product or service
3. Appraisal costs - costs incurred to determine the degree of
conformance to quality requirements
4. Prevention Costs - Costs incurred to keep failure and appraisal costs to
minimum.
From the above figure it can be understood that quality at which the total cost
curve is minimum
3. Present the sequential steps to be followed for Strategic Quality Planning
It sets the long term direction of the organization in which it wants to proceed
in future. Can be defined "As the process of deciding on objectives of the
organization, on changes on this objective, on the resource used to obtain these
objectives and on the policies that are to govern the acquisition use and
disposition of these resources"
The steps to achieve strategic quality are
4. Explain the Total Quality Management Model
A holistic approach to long-term success that views continuous improvement in all
aspects of an organization as a process and not as a short-term goal. It aims to radically
transform the organization through progressive changes in the attitudes, practices,
structures, and systems.
Total quality management transcends the product quality approach, involves everyone
in the organization, and encompasses its every function: administration,
communications, distribution, manufacturing, marketing, planning, training, etc.
Coined by the US Naval Air Systems Command in early 1980s, this term has now taken
on several meanings and includes
(1) commitment and direct involvement of highest-level executives in setting quality
goals and policies, allocation of resources, and monitoring of results;
(2) realization that transforming an organization means fundamental changes in basic
beliefs and practices and that this transformation is everyone's job;
(3) building quality into products and practices right from the beginning;
(4) understanding of the changing needs of the internal and external customers, and
stakeholders, and satisfying them in a cost effective manner;
(5) instituting leadership in place of mere supervision so that every individual performs
in the best possible manner to improve quality and productivity, thereby continually
reducing total cost;
(6) eliminating barriers between people and departments so that they work as teams to
achieve common objectives; and
(7) instituting flexible programs for training and education, and providing meaningful
measures of performance that guide the self-improvement efforts of everyone involved.
5. What are the barriers for implementation of Total Quality Management?
TQM is management philosophy that seeks to integrate all organizational functions
(marketing, finance, design, engineering, production, customer etc) to focus on meeting
customer needs and organizational objectives. TQM views an organization as a
collection of processes. It maintains that organizations must always strive to
continuously improve these processes by incorporating the knowledge and experiences
of workers.
Implementation of Quality
The implementation of total quality is similar to that of other decentralized control
methods. In developing TQM, companies need to understand how consumers define
quality in both goods and services offered. If a company pays more attention to quality
in its production processes, fewer problems are bound to occur when the product is in
the customers’ hands. Management should make a commitment to measure the
performance of a product relative to its quality through customer surveys, which can
help managers to identify design, manufacturing or any other process that has a bearing
on the quality of a product or service, and therefore provide an opportunity for
continuous improvement.
An obstacle is an object, a thing, an action or a situation that causes an obstruction.
Obstacles can be physical, social, economic, technological or political. There are a
number of barriers that face the process of TQM implementation. Discussed below are
some of the barriers or obstacles that total quality management face during
implementation
1. Competitive markets
2. Bad
attitudes/abdication of
responsibility/management
infallibility
3. Lack of leadership for quality
4. Deficiency of cultural dynamism
5. Inadequate resources for total quality management
6. Lack of customer focus
7. Lack of effective measurement of quality improvement
8. Poor Planning
9. Lack of management commitment
10. Resistance of the workforce
11. Lack of proper training/Inadequate Human Resource
