Kaizen refers to continuous incremental improvement. It is a Japanese philosophy that focuses on continuous improvement involving everyone in the organization on an ongoing basis. The goal of Kaizen is to eliminate waste through small, incremental changes to processes. It aims to improve all aspects of an organization over time. Kaizen emphasizes identifying and eliminating non-value added activities and focusing on activities that customers are willing to pay for. The 5S methodology is a tool used in Kaizen to organize and standardize the workplace. Toyota popularized Kaizen as part of their lean manufacturing system to drive cost reductions and quality improvements.

First made popular by Toyota as part of their
production system (TPS or Lean Manufacturing) in
the 1970s
“Discovered” and described in books in the West
starting in the 1980s
Popular in American Auto and Aerospace industries
in the 1990s (“Kaizen Blitz”)

8. Kaizen has 3 main principles
Consider the process and the results.
The need to look at the entire process of the job at hand and
to evaluate the job so as to find the best way to get it done.
Kaizen must be approached in such a way that no one is
blamed.
Kaizen event steps:
Select an Event
Plan an Event
Implement an Event
Follow-up to an Event

9. CONTINUOUS IMPROVEMENT
• Kaizen refers to improvement of both
processes and people.
• In fact Kaizen philosophy aims at
improving all aspects of an organization all
the time.
• Good is never good enough; kaizen is a
never-ending journey to excellence.

 Value and non-value added work activities
 Muda-seven classes of waste
 Principles of motion study and work-cell use
 Principles of materials handling and use of
one-piece flow
 Documentation of standard operating
procedures
 The 5S’s
 Visual displays for communicating to factory
personnel
 JIT- to produce right quantities at right
time and with right resources
 Poka-yoke to prevent or detect errors
 Team dynamics – problem solving
,communication skills, conflict resolving.

Different Types of Activities
Being able to tell the difference between NVA and VA
activities is an important step in the Improvement Process.
Value Added
Activity (VA)
An activity that changes raw
material to meet customer
expectations.
Non Value Added
Activity (NVA)
Those activities that take
time, or occupy space but
do not add to the value of
the product.
You must ask yourselves “Would you as a customer be
willing to pay for any NVA activity being performed to that
NEW 4x4 Pickup you just ordered?”

14. Kaizen’s Basic Goal

Discover and Eliminate all Waste in a process
Waste (“Muda”) – anything that the customer does
not pay for
Some waste is necessary or required by law
(personnel files, financial records, meetings,
maintenance)

16. 5 ‘S’ in KAIZEN5 ‘S’ in KAIZEN
• 5S is a method for organizing a
workplace, especially a shared
workplace (like a shop floor or an
office space), and keeping it
organized.
• To take the concept of Kaizen
performance to its ultimate level of
simplicity, it offered the following "5S"
steps
• Sorting keeping only
essential items
• Simplifying eliminates extra
motion.
• Sweeping keep the
workplace clean
• Standardizing standardized
work practices
• Sustaining maintaining and reviewing
standards
• .

17. BENEFITS OF KAIZANBENEFITS OF KAIZAN
• Kaizen Reduces Waste- like
inventory waste, time waste,
workers motion
• Kaizen Improves space
utilization, product quality
• Results in higher employee
moral and job satisfaction, and
lower turn-over.
• Toyota is well-known as one of the
leaders in using Kaizen. In 1999 at
one U.S. plant, 7,000 Toyota
employees submitted over 75,000
suggestions, of which 99% were
implemented.
.

18. Before Kaizen
• Components
kept under
workstation

19. After Kaizen
• Tooling bins are
easily traceable

20. Pitfalls in KAIZENPitfalls in KAIZEN
Resistance to change
Lack of proper procedure to implement
Too much suggestion may lead to confusion and
time wastage

21. Good is never good enough, kaizen is a never-ending
journey to excellence.
