INTRODUCTION
Quality-based organizations shouldstrive to achieve perfection
by continuously improving the business and
production processes. Of course, perfection is impossible
because the race is never over; however, we must
continually strive for its attainment.
4.
IMPROVEMENT IS MADEBY:
• Viewing all work as a process, whether it is associated with production or business activities.
• Making all processes effective, efficient, and adaptable.
• Anticipating changing customer needs.
• Controlling in-process performance using measures such as scrap reduction, cycle time, control
charts, and so forth.
• Maintaining constructive dissatisfaction with the present level of performance.
• Eliminating waste and rework wherever it occurs.
• Investigating activities that do not add value to the product or service, with the aim of
eliminating those activities.
• Eliminating nonconformities in all phases of everyone’s work, even if the increment of
improvement is small
5.
IMPROVEMENT IS MADEBY:
• Using benchmarking to improve competitive advantage.
• Innovating to achieve breakthroughs.
• Incorporating lessons learned into future activities.
• Using technical tools such as statistical process control (SPC), experimental design,
benchmarking, quality function deployment (QFD), and so forth.
Continuous process improvement is designed to utilize the resources of the organization to achieve
a quality-driven culture. Individuals must think, act, and speak quality. An organization attempts to
reach a single-minded link between quality and work execution by educating its constituents to
“continuously” analyze and improve their own work, the processes, and their work group.

THE JURAN TRILOGY
Planning
Theplanning component begins with external customers. Once quality
goals are established, marketing determines the external customers,
and all organizational personnel (managers, members of
multifunctional teams, or work groups) determine the internal
customers.
1. being a user of the product or service.
2. communicating with customers through product or service
satisfaction and dissatisfaction information.
3. simulation in the laboratory.
8.
THE JURAN TRILOGY
Control
Controlis used by operating forces to help meet the product, process, and service
requirements. It uses the feedback loop and consists of the following steps:
1. Determine items/subjects to be controlled and their units of measure.
2. Set goals for the controls and determine what sensors need to be put in place to
measure the product, process, or service.
3. Measure actual performance.
4. Compare actual performance to goals.
5. Act on the difference
9.
THE JURAN TRILOGY
Improvement
Thethird part of the trilogy aims to attain levels of performance
that are significantly higher than current levels. Process
improvements begin with the establishment of an effective
infrastructure such as the quality council. Two of the duties of
the council are to identify the improvement projects and
establish the project teams with a project owner.
In addition, the quality council needs to provide the teams with
the resources to determine the causes, create solutions, and
establish controls to hold the gains.

IMPROVEMENT STRATEGIES
Repair
This strategyis simple—anything broken must be fixed so that it functions
as designed. There are two levels to this strategy. If a customer receives a
damaged product, a quick fix is required. This level is a temporary or short-
term measure. Although short-term measures shore up the problem, they
should not become permanent.
Refinement
This strategy involves activities that continually improve a process that is
not broken. Improvements to processes, products, and services are
accomplished on an incremental basis. Refinement improves efficiency and
effectiveness. It should become an integral part of every employee’s job.
Both individuals and teams can
use this strategy.
11.
IMPROVEMENT STRATEGIES
Renovation
This strategyresults in major or breakthrough improvements. Although the
resulting product, service, process, or activity might often appear to be
different from the original, it is basically the same. Innovation and
technological advancements are key factors in this approach. For example,
the process of drilling a hole was originally done by hand with a cranking
mechanism; however, with the advent of the electric motor, the electric drill
was born.
Reinvention
Reinvention is the most demanding improvement strategy. It is preceded by
the feeling that the current approach will never satisfy customer
requirements. A new product, ser-vice, process, or activity is developedusing
teams based on a complete understanding of the customer’s requirements
and expectations.
12.
TYPE OF PROBLEM
Compliance
complianceproblems occur when a structured system having standardized
inputs, processes, and outputs is performing unacceptably from the user's
viewpoint.
The POSA Cycle
Unstructured problems resemble compliance problems except that they are
not specified by standards.
Efficiency
Efficiency problems occur when the system is performing unacceptably from
the viewpoint of its owners or operators.
13.
TYPE OF PROBLEM
Processdesign
Process-design problems involve the development of new processes and
revision of existing processes.
Product Design
Product-design problems involve the development of new products and the
improvement of existing products. A major focus is to prevent process and
end user problems by relying on customer needs.
PROBLEM SOLVING METHOD
Phase1: Identify the Opportunity
Phase 2: Analyze the Current Process
Phase 3: Develop the Optimal Solution
Phase 4: Implement Changes
Phase 5: Study the Results
Phase 6: Standardize the Solution
Phase 7: Plan for the Future
16.
KAIZEN
Kaizen is aJapanese word for the philosophy that defines management’s role
in continuously encouraging and implementing small improvements involving
everyone. It is the process of continuous improvement in small increments
that make the process more—efficient, effective, under control, and
adaptable. Improvements are usually accomplished at little or no expense,
without sophisticated techniques or expensive equipment. It focuses on
simplification by breaking down complex processes into their sub-processes
and then improving them.
17.
KAIZEN
The Kaizen improvementfocuses on the use of:
1. Value-added and non-value-added work activities.
2. Muda, which refers to the seven classes of waste—over-production,
delay, transportation, processing,
inventory, wasted motion, and defective parts.
3. Principles of motion study and the use of cell technology.
4. Principles of materials handling and use of one-piece flow.
5. Documentation of standard operating procedures.
18.
KAIZEN
6. The fiveS’s for workplace organization, which are five Japanese words
that mean proper arrangement (seiko), orderliness (seiton), personal
cleanliness (seiketso), cleanup (seiso), and discipline (shitsuke).
7. Visual management by means of visual displays that everyone in the
plant can use for better communications.
8. Just-in-time principles to produce only the units in the right
quantities, at the right time, and with the right resources.
9. Poka-yoke to prevent or detect errors.
10. Team dynamics, which include problem solving, communication
skills, and conflict resolution.
19.
REENGINEERING
According to Hammerand Champy, reengineering is the fundamental
rethinking and radical redesign of business processes to achieve
dramatic improvements in critical measures of performance.15 Many
practitioners believe that TQM is associated with only incremental
improvements. Nothing could be further from the truth—for many
years, the Malcolm Baldrige National Quality Award has defined
continuous improvement as referring to both incremental and
“breakthrough” improvement. The Japanese have not only relied on
kaizen but have developed policy management (hoshin kanri) and policy
deployment (hoshin tenkai) in large part to produce the kind of large-
scale breakthroughs that Hammer and Champy promote. Nor is this
concept uniquely Japa-nese. Joseph Juran has had a long-standing
emphasis on breakthrough efforts aimed at achieving unprecedented
levels of performance.

SUMMARY
Continuous improvement isan essential aspect of TQM philosophy and
implementation. The Juran Trilogy of Quality Planning, Quality Control
and Quality Improvement provides a conceptual framework for
continuous improvement. There are four improvement strategies:
repair, refinement, renovation and reinvention. Choice of the
appropriate strategy for various situations is critical. The PDSA cycle
developed by Shewhart and then modified by Deming provides a
roadmap to continuous improvement. Structured problem-solving
method can be easily blended with the PDSA cycle. Important
philosophies deployed by various organizations include Kaizen,
Reengineering and Six Sigma. Kaizen relies heavily on involvement of all
employees while Six Sigma relies more on fewer project leaders called
black and green belts. Success of any approach requires fully committed
management
