INTRODUCTION
Quality is not an act, it is a habit.
- Aristotle
In its broadest sense, quality is a degree of excellence: the extent to which something is fit for
its purpose. In the narrow sense, product or service quality is defined as conformance with
requirement, freedom from defects or contamination, or simply a degree of customer
satisfaction. In quality management, quality is defined as the totality of characteristics of a
product or service that bears on its ability to satisfy stated and implied needs. Quality is also
rapidly embracing the nature or degree of impact an organisation has on its stakeholders,
environment and society.
Quality is important to businesses but can be quite hard to define. Customers want quality
that is appropriate to the price that they are prepared to pay and the level of competition in the
market.
Key aspects of quality for the customer include:
Good design – looks and style
Good functionality – it does the job well
Reliable – acceptable level of breakdowns or failure
Consistency
Durable – lasts as long as it should
Good after sales service
Value for money
‘Value for money’ is especially important, because in most markets there is room for
products of different overall levels of quality, and the customer must be satisfied that the
price fairly reflects the quality. For example, the car maker Skoda is now part of the
Volkswagen group which is well-known for quality cars, but prior to this, Skoda owners were
amongst the most loyal because even though the cars fell short of most others in style,
comfort and performance, they were tough, reliable and very good value for money.
Some products and services are marketed as ‘basic’, having none of the extra features and
benefits of more expensive alternatives. Good examples would be Easyjet and George at
Asda clothing ranges. Even though it may be ‘low quality’ in terms of style or features, these
products still give good value for money for their overall level of quality.
For the firm, good design is fundamental, so that the product can be produced efficiently,
reliably and at the lowest possible cost. Also see the revision note on Quality Improvement.
If products are being made for other, large firms, then the quality standards may be dictated
by the firm placing the order.
Quality helps determine a firm’s success in a number of ways:
Customer loyalty – they return, make repeat purchases and recommend the product or
service to others.
Strong brand reputation for quality
Retailers want to stock the product
As the product is perceived to be better value for money, it may command a premium
price and will become more price inelastic
Fewer returns and replacements lead to reduced costs
Attracting and retaining good staff
These points can each help support the marketing function in a business. However, firms have
to work hard to maintain and improve their reputation for quality, which can easily be
damaged by a news story about a quality failure. See the Tutor2U Business Blog story about
Cadburys and salmonella.
Aside from achievement of standards like BSI, firms can measure quality aspects such as:
Failure or reject rates
Level of product returns
Customer complaints
Customer satisfaction – usually measured by a survey
Customer loyalty – evident from repeat purchases, or renewal rates
A detailed analysis of areas such as these would be an important part of Quality
Improvement – see the separate revision note for more details
Some areas for evaluation
Quality is subjective, it is a matter of personal opinion and what constitutes an
acceptable level of quality will vary from one individual to another.
Not all aspects of quality are tangible – for example the degree of assurance given by
a firm’s name or reputation can be very important even though it is hard to measure.
Quality is always evolving because of things like improved technology, better
materials, new manufacturing techniques and fresh competitors. No firm can afford to
stand still as far as quality is concerned.
Whilst controlling quality has benefits to the firm, it can also be costly to do, so it is
important that the benefits outweigh the costs in the long term.
LITERATURE REVIEW
"Quality is free. It's not a gift, but it's free.
The 'unquality' things are what cost money."
- Philip B. Crosby
Definition of Quality
Defining quality is far from easy. Just try to find why you find that a product is not of quality.
Is a Mercedes a high quality car ? Is a Lada ? Is a course of quality ?
What is Quality ?
ity
The notion of quality often subsumes a comparison between products. Product A is better
than B and therefore has a higher quality. However, the word "better" is vague and different
definitions can be used.
Quality:
lies "comparison"
Evolution of Quality Concepts
Here we detail how the definition of quality did evolve over time.
1) Fitness to standard
It just says that a product is of quality if it is what it is supposed to be.
definition: conformance to the specifications
The quality is thus checked by comparison between the output and the specifications.
Methods: - Standardization;
- Statistical quality control;
- Inspection.
Standardization is the set of actions taken for the product and the process to be clearly
identified. A set of written procedures for example. The classical test for checking whether\
standardization has taken place is: "If the people go, do the procedures stay ?" Inspection is a
simple mean by which the items are sorted. Good items are kept and bad ones are dropped.
We can decide to check all the products (total inspection) or only some of them (statistical
control). Inspection plans are discussed later in this chapter.
Drawbacks:
- Inspectors are "the enemy";
- Inspections do not add any value;
- Conformance to specifications does
- not mean conformance to needs
Based on this last drawback, the following definition was introduced.
2) Fitness of use
Here, a product is of quality if it performs as expected not as specified. The difference is
between the intended use of a product (its specification) and its real use.
A screwdriver is specified for a given size. We generally want to use the same screwdriver
for any kind of screws and maybe for opening a can of paint. Note that the fitness of use is
difficult to reach since this use may vary over customers and time.
Methods: market research / contact
Here we enter the world of marketing. The only way is to ask the consumer.
Drawbacks:
- Inspectors are "the enemy";
- Inspections do not add any value
"Fitness of use" supposes that definition of the specifications are "consumer based". Fitness
of use requires thus fitness to (the new) specifications and therefore also requires inspections.
Higher quality implies better inspection and therefore higher costs. Too large inspection costs
could also be dangerous. The answer is then the following. Instead of "inspecting" the quality
of the product, the focus came on "building" the quality in the product.
3) Fitness of cost
This means high quality in the eye of the users but now at low or reasonable cost.
o the expected price.
To reach this goal you need to reduce the variability of the processes so that no products have
to be discarded (and therefore none need to be checked). The only way of reaching this goal
is to control the processes and not the products.
Methods:
- Statistical quality control (SQC)
- Stochastic process control (SPC);
- Providing feedback at each step;
- Promote participation of the workers in the design and improvement.
VARIOUS QUALITY INITIATIVES IN INDIAN FIRMS
“At the Tata group, we are committed to improving the
quality of life of the communities we serve”
- TATA GROUP
TOTAL QUALITY MANAGEMENT
A cardinal principle of Total Quality escapes too many managers: you cannot
continuously improve interdependent systems and processes until you progressively
perfect interdependent, interpersonal relationship.
- Stephen Covey
Total quality management (TQM) consists of organization-wide efforts to install and make
permanent a climate in which an organization continuously improves its ability to deliver
high-quality products and services to customers. While there is no widely agreed-upon
approach, TQM efforts typically draw heavily on the previously developed tools and
techniques of quality control. TQM enjoyed widespread attention during the late 1980s and
early 1990s before being overshadowed by ISO 9000, Lean manufacturing, and Six Sigma.

QUALITY STANDARDS IN INDIAN FIRMS
BIS –BEARAU OF INDIAN STANDARDS
The Bureau of Indian Standards (BIS) is the national Standards Body of India
working under the aegis of Ministry of Consumer Affairs, Food & Public Distribution,
Government of India. It is established by the Bureau of Indian Standards Act, 1986 which
came into effect on 23 December 1986. The Minister in charge of the Ministry or
Department having administrative control of the BIS is ex-officio President (Emaad
Amin) of the BIS.
BIS hallmarking Scheme is voluntary in nature and is operating under BIS Act, Rules and
Regulations. It operates on the basis of trust and thus it is desirable that aspects of quality
control are in built in the system responsible for managing quality. The BIS Hallmarking
Scheme has been aligned with International criteria on hallmarking (Vienna Convention
1972). As per this scheme, licence is granted to the jewellers by BIS under Hallmarking
Scheme. The BIS certified jewellers can get their jewellery hallmarked from any of the
BIS recognized Assaying and Hallmarking Centre. The recognition to an Assaying and
Hallmarking Centre is given against BIS criteria Doc: HMS/RAHC/GO1 which is in line
with International criteria on Marking and Control of Precious metals.
Fig 5: BIS HALLMARK

customers.
MILMA GHEE
Contains 99.7 percent milk fat. Manufactured by melting fresh cream under hygienic
conditions. Milma ghee has the ideal golden yellow colour due to presence of natural
carotene in cow milk. (In contrast, ghee manufactured from buffalo milk is white in color).
No artificial colours or flavours are added in Milma ghee. Natural aroma and flavour of ghee
is retained since ghee is produced directly from fresh cream instead of going in for melting
stored butter Made from cow’s milk, the golden colour Milma ghee which is Agmark
Certified is famous for its aroma and taste. Available in consumers packs of 50ml, 100ml,
200ml, 500ml, 1 ltr, 2 ltr, and 5 ltr PET Jars.
ISO
The International Organization for Standardization (French: Organisation internationale
de normalisation; Russian: Международная организация по стандартизации, tr.
Myezhdunarodnaya organizatsiya po standartizatsii), known as ISO, is an international
standard-setting body composed of representatives from various national standards
organizations.
Founded on 23 February 1947, the organization promotes worldwide proprietary, industrial
and commercial standards. It is headquartered in Geneva, Switzerland, and as of 2013 works
in 164 countries. It was one of the first organizations granted general consultative status with
the United Nations Economic and Social Council.
The three official languages of the ISO are English, French, and Russian. As its name would
have different abbreviations in different languages ("IOS" is English, "OIN" in French, etc.),
the organization adopted as its abbreviated name "ISO", derived from the Greek word isos
(ἴσος, meaning equal).
Both the name "ISO" and the logo are registered trademarks, and their use is restricted.
ISO is a voluntary organization whose members are recognized authorities on standards, each
one representing one country. Members meet annually at a General Assembly to discuss
ISO's strategic objectives. The organization is coordinated by a Central Secretariat based in
Geneva.

process compliance and hence certifications like ISO 9001 and COPC were much sought
after. Over the years constant innovation led us to embrace improvement methodologies such
as Lean, Six Sigma, Kaizen, Continuous Improvement, etc. to further strengthen the
efficiency of the processes. Some Indian BPO companies have become extremely proficient
in the application of these methodologies for internal processes as well as in their customer’s
organizations, hence significantly achieving process and people excellence.
SIX SIGMA IN INDIAN FIRMS
A statistical concept that measures a process in terms of defects – at the six sigma level, there
3.4 defects per million opportunities. Six Sigma - A highly disciplined process that enables
organizations deliver nearly perfect products and services. A methodology and a symbol of
quality to measure and improve company’s performance, practices and systems. It mainly
aims at enhancing the profitability by improving the quality and efficiency. It is a structured
data driven methodology for eliminating waste from processes, products and other business
activities while having a positive impact on performance. Six Sigma emerged as a natural
evolution in business to increase profit by eliminating defects.
Six Sigma is a rigorous and a systematic methodology that utilizes information (management
by facts) and statistical analysis to measure and improve a company's operational
performance, practices and systems by identifying and preventing 'defects' in manufacturing
and service-related processes in order to anticipate and exceed expectations of all
stakeholders to accomplish effectiveness.

SAMSUNG
Samsung Electronics Co. (SEC) of Seoul, Korea, is perfecting its fundamental approach to
product, process and personnel development by using Six Sigma as a tool for innovation,
efficiency and quality. SEC was founded in 1969 and sold its first product, a television
receiver, in 1971. Since that time, the company has used tools and techniques such as total
quality control, total process management, product data management, enterprise resource
management, supply chain management and customer relationship management. Six Sigma
was added to upgrade these existing innovations and improve SEC’s competitive position in
world markets. The financial benefits made possible by Six Sigma, including cost savings
and increased profits from sales and new product development, are expected to approach $1.5
billion by the end of 2002.
As a foundation for its Six Sigma thrust, SEC began by pursuing a pervasive goal of
developing its internal resources, especially people, to put innovation first in the development
and design of products, in manufacturing and marketing, and in the growth of employees.
With its strategic objectives established, the foundation was ready for the Six Sigma process
to begin in late 1999 and early 2000 with training for SEC’s management, Champions and
other employees responsible for deployment planning. The Juran Institute Inc. provided this
training. After only three years of deployment, the number of Master Black Belts (MBBs),
Black Belts (BBs) and Green Belts (GBs) already approaches 15,000—or almost one of every
three employees. With a corporate goal of 100 MBBs, 3,000 BBs and 30,000 GBs by 2004,
SEC obviously is serious about developing Six Sigma capability in a workforce of about
49,000 worldwide in 89 offices and 47 countries. No individual or operation in SEC is
exempted from the training—including staff members in management, personnel, accounting
and procurement. BBs are expected to guide several projects per year, which further increases
each project’s return on investment. Promotion and other awards and incentives are awarded
by the operation in which each employee is assigned.
SEC completed 3,290 Six Sigma projects in 2000 and 2001; 1,512 of these were BB projects.
In 2002, 4,720 projects are expected to be completed, 1,640 of them by BBs. SEC’s Six
Sigma projects have also contributed to an average of 50% reduction in defects between 1999
and 2001. There is no thought of improvement in quality and productivity without Six Sigma.
These impressive numbers have certainly played a major role in Samsung’s recent growth.
Some indications of this include the following:
• By 2001, SEC had earned net income of $2.2 billion on total revenues of $24.4 billion.
Market capitalization stood at $43.6 billion.
• According to SEC’s 2001 annual report, SEC now is one of the top 10 electronic and
electrical equipment manufacturing companies in the world, with the best operating profit
ratios and superior fiscal soundness.
• The report also says debt to equity ratio is lower than that of any top ranking company, and
the shareholders equity to net assets ratio surpasses the average.
• SEC says its technological strengths, Six Sigma quality initiatives and product marketability
helped increase its share of the memory chip market in 2001 to 29%, monitors to 21% and
microwave ovens to 25% of those sold worldwide.
• Despite a downturn in the world economy and a reduction in exports to the United States,
credit for SEC’s current operating profit margin of 8.5% is due mostly to quality
improvements and Six Sigma deployment.
• SEC’s quality and innovative strategy helped it reach the number one position in the
BusinessWeek 2002 information technology guide.1, 2 The guide noted SEC’s computer
monitors, memory chips, telephone
handsets, and other digital products, focusing on four Standard & Poor’s criteria: shareholder
return, return on equity, revenue growth and total revenues.
Samsung believes the BusinessWeek ranking was also due to SEC’s employees’ belief that
quality is the single most important reason for the company’s higher sales, lower costs,
satisfied customers and profitable growth.
Only a few years ago, SEC’s products were virtually unknown by Americans or were known
as the cheaper, lower quality substitute for Japanese brands. This perception is changing. The
U.S. market now represents 37% of SEC’s total sales.

procedure at Wipro Technologies and the benefits reaped by the company on account of
adopting Six Sigma. The case also throws light on the recent developments in the Six Sigma
concept including Wipro’s Six Sigma Skill base and consulting experience and explains
how the company intends to build its expertise and experience – to bring continuous process
improvement to the organization.
Six Sigma at Wipro Technologies: Thrust on Quality
Backdrop
Wipro Limited was established in 1945 and commenced its operations in 1946 as a vegetable
oil company. In the early 1980s, Wipro diversified into the Information Technology sector
with Liberalization hitting India in the 1980s. This has been a fascinating transformation from
a vegetable oil company into a global IT services giant. Today, Wipro Technologies has
become a global service provider delivering technologydriven business solutions that meet
the strategic objectives of clients. Wipro has 40+ ‘Centers of Excellence’ that create solutions
related to specific needs of Industries. Wipro can boast of delivering unmatched business
value to customers through a combination of process excellence quality frameworks and
service delivery innovation. A strong emphasis upon building a professional work
environment, leaders from within, and having a global outlook for business and growth have
led to innovation of people processes on a continued basis. Over the years, Wipro has
significantly strengthened its competency based people processes and demonstrated
innovative practices in talent acquisition, deployment, and development, based on strategic
needs.
A leading provider of communication networks in the US required improvement in
the product performance of a telecom application using Six Sigma methodologies. Thus, with
the growing importance on aligning business operations with customer needs and driving
continuous improvement, Wipro began moving towards focusing on Quality, thereby,
creating a learning environment that led to implementation of Six Sigma. Prepared by Dr.
Manisha Sharma, Dr. Kapil Pandla and Prof. Prashant Gupta of Jaipuria Institute of
Management, Noida . This case is prepared solely for the basis of class discussion. Cases are
not designed to present illustrations of either correct or incorrect handling of administrative
problems.
Integrating Six Sigma concepts was also intended to bring rigor in effective upstream
processes of the software development life cycle. Implementation of Six Sigma
methodologies brought in quantitative understanding, cost savings, and performance
improvement towards product quality. Some of the key challenges involved were:
Reduce the data transfer time
Reduce the risk
Avoid interruption due to LAN/WAN downtime.
Parallel availability of the switch for the other administrative tasks during the same period.
:
What is Six Sigma?
The word is a statistical term that measures how far a given process deviates from perfection.
Six Sigma is named after the process that has six standard deviations on each side of the
specification window. It is a disciplined, data-driven approach and methodology for
eliminating defects. The central idea behind Six Sigma is that if you can measure how many
“defects” you have in a process, you can systematically figure out how to eliminate them and
get as close to “zero defects” as possible.
Six Sigma starts with the application of statistical methods for translating information from
customers into specifications for products or services being developed or produced. Six
Sigma is the business strategy and a philosophy of one working smarter not harder. One
sigma gives a precision of 68.27%., two sigma, of 95.45% and three sigma of 99.73%,
whereas Six Sigma gives a precision of 99.9997%.Although 99.73% sounds very good, it
slowly dawned on companies that there is a tremendous difference between 99.73% and
99.9997%. For ex. For every million articles of mail, the difference is between 66,738 lost
items and 3.4 lost items
To achieve Six Sigma Quality, a process must produce no more that 3.4 defects per million
opportunities. An opportunity is defined as a chance for nonconformance, or not meeting the
required specifications. This means one needs to be nearly flawless in executing key
processes. The process and culture is conditioned for zero defects rather than being one that
accepts that it is inevitable, and acceptable, that mistakes will occur.
Hence Six Sigma delivers substantial cost reductions, enhanced efficiencies, sustainable
improvements and increased stakeholder value.
Evolution of Six Sigma at Wipro
Wipro is the first Indian company to adopt Six Sigma. Today, Wipro has one of the most
mature Six Sigma programs in the industry ensuring that 91% of the projects are completed
on schedule, mush above the industry average of 55%. As the pioneers of Six Sigma in India,
Wipro has already put around ten years into process improvement through Six Sigma. Along
the way, it has scaled Six Sigma ladder, while helping to roll out over 1000 projects. The Six
Sigma program spreads right across verticals and impacts multiple areas such as project
management, market development and resource utilization.
Six Sigma at Wipro simply means a measure of quality that strives for near perfection. It is an
umbrella initiative covering all business units and divisions so that it could transform itself in
a world class organization. At Wipro, it means:
(i) Have products and services meet global benchmarks
(ii) Ensure robust processes within the organization
(iii) Consistently meet and exceed customer expectations
(iv) Make Quality a culture within.
Difficulties encountered by Wipro and learning from them:
Build the Culture:
Implementation of Six Sigma required support from the higher level managers. It meant
restructuring of the organization to provide the infrastructure, training and the confidence in
the process. Wipro had to build this culture and that took time in implementation.
Project selection:
The first year of deployment was extremely difficult for Six Sigma success. They decided to
select the project on the basis of high probability of their success and targeted to complete
them in a short period to assess the success. These projects were treated as pilot projects with
a focus to learn. For the selection of the right project the field data was collected, process
map was developed and the importance of the project was judged from the eyes of customers.
Training: After the set up, the first step of implementation was to build a team of
professionals and train them for various stages of Six sigma. The training was spread in five
phases: Defining, measuring, analyzing, improving and controlling the process and lastly
increasing customer satisfaction. These phases consisted of statistics, bench marking and
design of experiments. To find the right kind of people and train them was a difficult job.
This motivated Wipro to start their own consultancy to train the people.
Resources:
It was difficult to identify resources that required for short-term basis and long-term basis as
it varied from project to project. Wipro did it on the basis of seriousness and importance of
the project.
Project Reviews:
As timely reviews play a very crucial role to judge the success of a project. Wipro had to
develop a team of experts for this purpose. The task assigned was to see the timeliness, find
out gap, week areas and to check the outcome as per the plan.
Implementation of Six Sigma at Wipro
Wipro has adopted the project approach for Six Sigma, where projects are identified on the
basis of the problem areas under each of the critical Business Processes that adversely
impacts the business significantly.
Wipro has evolved following Six Sigma methodologies :
(I) For developing new processes:
(i) DSSS+ Methodology –Wipro employs DSSS methodology for software development. The
methodology uses rigorous in-process metrics and cause analysis throughout the software
development lifecycle for defect free deliveries and lower customer cost of application
development.
(ii) DSSP Methodology – used for designing new processes and products
(iii) DCAM Methodology – used for designing for customer satisfaction and
manufacturability
(II) For Improving Existing Processes
(i) TQSS Methodology –used for defect reduction in Transactional processes.
(ii) DMAIC Methodology -used for process improvement in Non-transactional process
(III) For Reengineering
CFPM Methodology - used for cross functional Process mapping. The list of players at Wipro
is as below:
Executive Management
Six Sigma Champions and Deployment Leaders
Financial Executives
Black Belts
Green Belts
Yellow Belts
Six Sigma projects at Wipro are :
(i) Driven by business heads, also called Champions for the projects.
(ii) Led by Green Belts (GB)
Assisted by Black Belts (BB)
The Management of the project at Wipro follows the following tools for implementation of
Six Sigma:
Ideation
Definition
Selection
Tracking
Reporting
Currently 15000+ employees are trained in Six Sigma methodologies. Wipro has also
built up a Six Sigma skill base of over 180 certified black belts while helping to roll out
over a 1000 projects.
Six Sigma Consultancy at Wipro:
Wipro’s Six Sigma consulting experience has peaked with the indigenous development of
new methodologies that it takes to its customers. As Wipro continues Six Sigma consulting
journey, it builds on its expertise and experience- to provide enterprise-class coverage of
topics in business process management and information technology systems integration. The
focus is on supporting the project needs and is also integrated with other methods to support
process needs. Currently there are over 200 PMI certified consultants at Wipro. The Wipro
quality consulting group trains in achieving the precision of Six Sigma with Wipro’s own
methodologies, training capabilities and global experience. Wipro also helps in
institutionalizing Six Sigma across the organization for transformation.
Wipro provides consulting in institutionalizing an organization wide Six Sigma program that
specializes in implementation across IT development, production support and core business
operations.
Wipro offers the following Six Sigma consulting services :
Six Sigma institutionalization
Problem solving using six Sigma
Six Sigma training
Reaping the Benefits:
The financial gain that Wipro has achieved by using Six Sigma has been one of the high
points.
As the Six Sigma initiative started maturing Wipro identified two major phenomenon:
The biggest projects had all been completed
The Yellow-belt culture had cured little problems before they became big ones.
At this point, the project-oriented Six Sigma culture began to give way to the sustaining
culture.
The Six Sigma process resulted in an achievement of close to 250%, 6 minutes for 1 MB
transfer and 18 minutes for average data transfer. The set target was 200%. Because quality is
customer driven, the objective of Six Sigma Implementation at Wipro has continuously been
on integrating and implementing approaches through a simultaneous focus on defect
reduction, timeliness, and productivity. This has translated to lower maintenance costs,
schedule-overrun costs, and development costs for customers. Measurements and progress
indicators have been oriented towards what the customer finds important and what the
customer pays for. Towards this, Six Sigma concepts have played an important role in:
Improving performance through a precise quantitative understanding of the customer’s
requirements thereby bringing in customer focus
Improving the effectiveness in upstream processes of the software development life cycle
by defect reduction (software defects reduced by 50%) and cycle time reduction (rework in
software down from 12% to 5%).
Waste elimination and increased productivity up to 35%.
Cost of failure avoidance (installation failures down from 4.5% to 1% in hardware
business).
Tangible cost savings due to lower application development cost for customer.
Analysts remarked that Six Sigma was an indisputable success at Wipro whether in terms of
customer satisfaction, improvement in internal performance, or in the improvement of
shareowner value.
The results of achieving Six Sigma are rapid and overwhelming at Wipro Its unique
methodology provides Six Sigma knowledge and skills to the client, enabling the client to
create ownership, generate results and sustain success. The maturity of Wipro’s quality
processes takes the benefits to another level, ensuring that the customers benefit from:
30-40% lower total cost of ownership
20-30% higher productivity
On-time deliveries (93% projects completed on time)
Lower field defect rates (67% lower than industry average). The performance enhancement
enabled the client to have an improved product with the overriding benefit that the end
customer perception of the quality of the client’s product is improved.
Future Focus and Challenges:
Six Sigma certainly produces breakthrough improvement. But to achieve this Wipro will
have to combine the power of the Six Sigma method and tools with stretch goals, goals that
almost seem too aggressive, too optimistic.. Also Wipro will have to benchmark itself against
the competition on the level of performance achieved by rivals.. This focus will lead to the
adaptation of newer dimensions of the quality management framework towards embodying a
totality of process, people, product, and technology for achieving high process capability. Six
Sigma projects require continuous change. Black Belts and Green belts develop
improvements to systems and processes for which they are not accountable. And when these
participants are done with their project, they ask the real system or process owner to
implement and sustain their solution and hence the challenge before Wipro lies in bringing
the commitment towards continuing its process optimization theory.
The Challenge will be to transform Six Sigma from a tool for improving product quality to an
overall business improvement methodology. The company’s aim will be at having
100% of its management trained in Six Sigma.
To summarize, the quality system will continue to be based on incremental optimization,
with rigorous implementation and sustenance of the same. The goal will be to make
quality as the No.1 objective for all employees.
