Lean Thinking

2. LEARNING OUTCOME:
• Understand the concepts of Lean Thinking
• Awareness of the 7 Wastes in Industries

4. Lean Thinking is…
• A systematic approach
• To identifying and eliminating waste
• Through continuous improvement
• By flowing the product/ information
• At the pull of the customer
• In pursuit of perfection
LEAN means CHANGE!

5. • Principle of “Just Enough”
• Practice of Questioning and Experimenting

6. 3 Types of Work in LEAN Environment
• Value Added
•Activity that changes the fit, form, or function
•Done right the first time
•Something the customer is willing to pay for
• Non-Value Added, but essential (at the moment)
– Activities that take time or resources, but do not
directly contribute to product/ service
– Incidental, or
• WASTE = MUDA

8. Muda = “WASTE”
Muda?
Any activity that consumes
resources without creating
value for the customer
Or
Any activity for which the
customer is not willing to
pay.

9. 1. OVERPRODUCTION
Producing greater quantities more than the customer demand
Examples:
• Batching schedule
• Excess Printing
• Multiple forms with the same information

10. Learn to see overproduction!
Overproduction is the worst form of waste
Because it generates and hides others wastes such as inventory, defects and excess transport
How do we eliminate them - Let’s connect the two processes and just keep 1 piece between x and y.
Without question there is some WIP
between process x and process y. That
is the waste of overproduction

11. 2. INVENTORY
Keeping unnecessary raw materials, parts, WIP (work-in-
process), and finished goods. More precisely, keeping more
than the minimum stock necessary for a well controlled pull
system.
Examples:
• Large batch sizes
• Wrong quantities of required items
on hand
• Paperwork in process

12. Accumulation
See stops, delays, or accumulation by
focusing on the flow of the product
Movement and Conveyance
See non-value creating motion by focusing on the
movement of people and machines.
Try looking from these viewpoints

13. Try looking from these viewpoints
Lowering the water level…

14. 3. WAITING
Operator standing idle as machines cycle, equipment fails, parts
delay, etc.
Examples:
• Operators without work
• Low rhythm of the operators

15. 4. MOTION
Operators making movements that are creating no value. We
can also identify waste in the motion of machines.
Examples:
• Not standardized workstation equipment
• Wrong spaced equipment
• Difficult access to the components

16. 5. TRANSPORTATION
Transportation or conveyance itself is waste because it creates
no value. Obviously, [arts and products must be transported,
but any movement beyond the absolute minimum is muda.]
Examples:
• Loading and Unloading are
very complicated
• A large number of means of transport

17. 6. DEFECTS
Inspection, rework and scraps.
Examples:
• A lot of rejected parts
• Difficulties during assembly
• Long repair jobs
• Irregular operations

18. 7. OVER PROCESSING
Unnecessary or incorrect processing.
Examples:
• Differences between the standard
and the activity
• A lot of activity which does not add
any value from the point

19. Goal: Highest quality, lowest cost and shortest lead time
