Introduction to 7 Mudas

3. Value added and Non Value added
3
Value Added Activity
● The activity changes the product towards something that the customer wants.
● Any part of the production process that improves the product for the customer.
● The customer would be willing to pay for it.
Non-Value Added Activity- Pure Waste
● Consumes resources but creates no value in the eyes of the customer. Can and should
be eliminated
● Examples: idle/wait time, rework, excess inspections, excess transportation(all seven
wastes are in this category)
Non-Value Added Activity–Necessary Waste
● No value is created, but can not be eliminated based on
current technology or policy
Examples : Company’s Mess / canteen, ISO compliance,
employee’s insurance etc.

5. 1) Waste of Over-production
This waste can be simply defined as doing or
making things those are not required now. Over
production generate excess inventory.
It may:
• Increase Transportation
• Consume resources before needed
• Occupy space to store excess products
5

6. 1) Waste of Over-production
6
Reasons
● Poor scheduling and planning
● Unbalanced cells or departments
● Working on forecast / inaccurate
information, not actual demand
● Bull Whip Effect
Counter measures
● Balance supply to demand
● One-piece flow
● Proper production planning

7. Real efficiency and pretended
efficiency
7
Wrong estimation

8. 2) Waste of Transportation
It may:
● Consume time and energy
● Require excess people and
management work
● Require excess equipment or
materials
● Cause to damage products
When work is transferred from one
place to another is a non-value added
activity.

9. 9
Reasons
● Batch production
● Push production
● Poor layout
● Lengthy or complex material
handling
Counter measures
● Standardization
● Optimum man and machine
layout
● Pull System
2) Waste of Transportation

12. Material Handling

13. 3) Waste of making defective products
13
Defective products are produce when
they deviate from what the customer
requires or the specification.
Defects interrupt the smooth flow of
production It may:
● Waste of material and efforts
● Require skilled persons for
repairing work
● Require skilled persons for
monitoring abnormality of
machine

14. 14
Reasons
● Process failure
● Incapable machines
● Inadequate training
Counter measures
● Fool-Proofing (POKAYOKE)
● Automation
● If you can’t prevent a defect-
making process then you must
stop the process
● Never send defective products
to the next process
3) Waste of making defective products

15. 4) Waste of movement
15
The excessive movement of man or
machine within the work space.
It takes time. (The manufacturing cost
increases)
It may:
● Consume time of his own as well as of
related people
● Make it difficult to establish standards
● Low worker moral
● cause more fatigue

16. 16
Reasons
● Poor workstation design,
excessive walking, bending.
● Unsafe work area
● Poor method design,
transferring parts from one
hand to an other
● Missing items
Counter measures
● Standardization
● Optimum man and machine’s
layout
● Study Motion Economy
4) Waste of movement

17. 17

18. 5) Waste of Over processing
18
Processes which don’t add value
to work.
Over processing is adding more
value to a product than the
customer actually requires
It may:
● Consume time of machine
operation
● Produce high quality products
which really not required by
customer
● Require skilled persons to
watch

19. 19
Reasons
● Customer voice not understood
● Designs “thrown over the wall”
● Inadequate technology or
design of process
● Bad machine maintenance
Counter measure
● Study thoroughly if the process
adds value or not
● If not, then think how to
eliminate the process
5) Waste of Over processing

20. 6) Waste of waiting
20
It is the act of doing nothing or
working slowly whilst waiting for
a previous step in the process.
It may:
● Consume time
● Cool down muscles
● Cool down high feeling
● Deteriorate morale

21. 21
Reasons
● Work imbalance
● Bad Process Design
● Lack of necessary goods
● Push production
● Lack of priority
● Lack of communication
Counter measure
● Standardization
● Line balancing
● One operator handles several
machines
● at once (Multi skilled worker)
● Leveling (quantity, variety,
timing)
6) Waste of waiting

22. Waiting time during M/C Process
22

23. 7) Waste of Inventory
23
Inventory is the raw materials, work
in progress (WIP) and finished goods
stock that is held, we often hold far
more than is required to produce
goods
It may:
● Consume time
● Consume space (area)
● Consume resources before it
needed

24. 24
Reasons
● Incapable process
● Lack of balance in work flow
● Making more than the
customer wants or in advance
of customer demand
Counter measure
● Just in Time (JIT) production
● balance your production
processes
● Use kanban system
7) Waste of Inventory
