Enhancement or Additional Features: It represents the
additional features supplementing the product’s basic
function.
Example: Auto power off when not in use, Telephone directory
storage, In built videogames, child lock facility etc.,
Reliability: Probability that a product is performing its intended
function over its intended life and under the stated
conditions.
27. Dimensions of quality cont..

Competence and ease of repair or reconditioning of a
product.
Aesthetics: Should appeal to senses. It is Human response to a
product . how it looks, feels, sounds, tastes or smells..
Reputation: Past performance, Brand image
29. Edwards Deming had
proposed fourteen principles
towards quality achievement.
These principles are summarized
as follows:
30. 1. Create and Publish the Aims and Purposes of the Organization:
Long range goals, resource allocation for innovation,
R&D, training and continuous education for the employees.
2. Adopt new philosophy :
Focus on the customer satisfaction,
prevention of non - conformance, rather than detection and correction,
3. Understand the Purpose of Inspection:
Eliminate the need for mass inspection by building quality into the product.
Mass inspection is costly and unreliable.
Mass inspection is managing for failure and Defect prevention is managing for
success
To improve the process and reduce its cost, use of statistical techniques should
be adopted.
31. 4. Stop Awarding Business Based on Price Alone:
End the practice of selecting the suppliers, based solely on
price.
Price is meaningless, without quality.
Minimize total cost by working with a single supplier, thereby
developing a long term ethical and economical relationship,
loyalty and trust with the suppliers.
5. Improve constantly and forever - the system of production and
service to improve quality and productivity and to decrease cost.
32. 6. Institute training on the job.
Each employee is to be trained in quality improvement skills,
communication skills, statistical methods and problem solving methods.
Management must allocate resource to train employees to perform their
jobs in the best possible manner.
7. Teach and Institute leadership:
Improving Supervision is Management’s responsibility.
Management must provide supervisors with training on analytical methods.
Instead of focusing on a negative, fault-finding atmosphere, Supervisors
should create a positive, supportive climate.
All communications must be clear from top management to supervisors to
operators.
33. 8. Drive out Fear, Create Trust, and Create a climate for Innovation:
Fear is caused by lack of job security, performance appraisal by
superiors, ignorance of organizational goals, poor supervision and poor
knowledge of the job.
All the employees are to be treated with dignity - Only then, they can
provide ideas and act upon for improvement.
Management must encourage open, effective communication and team
work.
Management can begin by providing workers with adequate training,
good supervision, and proper tools to do the job.
9. Optimize the Efforts of Teams and groups:
Break down barriers between departments, research, design, sales and
production .
must work together to foresee problems in production .
34. 10. Eliminate slogans, exhortations and numerical targets for the
workforce:
Goals - achievable and the methods are known and made available, to all the
employees.
Improvements in the process cannot be made unless the tools and methods are
available.
11. Eliminate quotas or work standards:
Quota and work standards give importance to quantity, rather than quality.
They encourage poor workmanship in order to meet their quotas
Instead of fixing quantity, the management must concentrate on the methods
for improvement and quality.
Statistical method of Process Control may replace Quotas.
35. 12.Remove barriers that rob people of their right to pride of
workmanship;
Loss of pride in workmanship occurs in organizations, because of the
following reasons:
Workers - unaware how to relate their efforts to the organization’s missions.
They are blamed for system failure.
Poor designs leading to waste of product or service.
Inadequate training.
Punitive supervision.
Inadequate or faulty equipments and tools provided for performing the job.
When workers feel proud of their work, they will grow fully and successfully,
in their job and out of their job.
13.Encourage Education and Self-Improvement
36. 14. Put everyone in the company to work to
accomplish the transformation.
Create a structure in top management that will
emphasize the preceding thirteen points every day.
The principles may be aptly called,
“codes of ethics for Quality”.
38. Barriers to TQM implementation
Lack of Management commitment
Inability to change Organisation culture
Improper planning
Inadequate use of empowerment
Lack of continuous training and education
Paying inadequate attention to internal and
external customers.
Failure to continually improve.
39. Quality Management
Quality Management - coordinated activities to direct and
control an
organization with regard to quality
QM = QP + QA + QC + QI
Quality Plan-focuses on setting quality objectives
Quality Assurance- providing confidence that quality
requirements will be fulfilled
Quality Control - focused on fulfilling quality requirements
Quality Improvement - focused on increasing the ability to
fulfill quality requirements.
40. Quality Management
Quality Planning: Planning process to meet the customer
requirements
Define Q. Policy, Objectives and requirements.
Statement describes an org commitment to Q.
Guides everyone in the org.
Plan about the resources.
Identify your customer, Determine their needs, Translate them
into your language, Develop a product.
Juran’s Q Planning..
44. Quality Cost
Cost incurred by the firm because of producing poor
quality products.
Cost associated with non achievement of product as
defined by the requirements.
Any cost associated with correcting failure or
reworking the finished product or wastage go into
Quality costs.
A reduction in Quality cost will lead to increased profit.
45. Quality Cost
Appraisal cost
Inspection and Testing of incoming material, In-process
inspection, Final inspection,
Product Inspection and Testing
Maintaining accuracy of test equipment.
Prevention Cost
Quality Planning & Inspection, New Products Review, Product
Process Design
Process Control, Quality training, TQM
Failure cost
Internal Failure Cost
External Failure cost.
48. Benchmarking
Concept of Benchmarking taken the new meaning since
1970s.
Companies compared the performance CY… LY
Parameters like cost, profit, sales volume, expenses,
etc…..Target
“The process of identifying, understanding, and adapting
outstanding practices and process from organisations
anywhere in the world to an organisation to improve its
performance”
…….Systematic and continuous measurement process………
49. Benchmarking
Systematic method by which organisations can measure
themselves against the best in class org in order to achieve
the best of the best.

BM is a tool generally used for continuous improvement.
It utilizes a systematic process for improving the
performance of product/service, process or an organization

company.
It was positioned as a ‘More car per car’
Maruti 800 as an inadequate car.
Prospects were car owners who had a 3-5 year old Maruti 800.
63. Xerox - Case analysis
Xerox 914 - First plain copier - 1959….New industry
During 1960’s high growth….selling all it could produce
CA.. STRONG PATENT, GROWING MARKET, LITTLE COMPETITION
No focus on customer
During 1970’s IBM, Kodak ,,,, several Japanese companies
High Q Low Volume copiers ……..ignored
Federal Trade commission accused Xerox ..illegally monopolizing the copier
business 1700 patents to competitors.
1980 market share fell down by less than 50 per cent.
Company would not survive
64. Xerox –Case analysis
Rework, scrap, excessive inspection, lost business costing more than
20 per cent of revenue, Comparing with competition
In 1983 company president David Kearns …need for long range
planning
Team……Quality strategy for Xerox
