Then & Now
7. What was “Then” ?
Cost Profit
Cost
Profit
Price
Customer was not
having many choice
and was bound to
pay this price.
Cost Plus
Over the years the worldwide the manufacturing industries has been following a practice
where they would add up their costs and they add on profit percentage and would sell to
customer on leave it or take it basis.

8. What is “Now”?

Customer is having
many choices and
can pay this price or
lower price.

Now the scene has changed, the competition is there and customer has many
choices and he wants to pay what he/she wants.

11. Price Profit Cost
What to Do?
Reduce Price, Maximize Profit & Reduce cost
100 - 20 = 80
90 - 20 = 70
90 - 25 = 65
Can We bring down the cost from 80 to 65?
7VmEe
12. Challenges- Can we bring the cost down?
Reduce the cost by relentlessly eliminating waste and improving
information and material flow.
Challenges- How to train ourselves to identify waste and problems?
“Yes”
We need to make at the cost which customer is willing to pay.
But How?
We need to train our eyes to Identify waste and problems.
But How?
7VmEe
13. Challenge-How to train our eyes?
Answer lies in Simulation
7VmEe
Where to train our eyes “quickly”, ”accurately” and
at “lesser cost”?
We have two options to train our selves
Option-1
At Actual Workplace
Option -2
At Simulated Work Environment
14. Challenge-How to train our eyes?

We need to choose “Simulated Work Environment” as it is
quick, accurate and at lesser cost
7VmEe
15. What to do in simulation?
We need to train our selves on Data Analysis and Problem Solving
and do improvements.
We have limited time for improvement and we need to use these
precious time wisely
We need to identify our most expensive problems
We Need to solve these most expensive problems
We want to standardize i.e. we will not solve the same problems
many a times
Answer lies in “Data Analysis” and “Problem Solving”

Where is Data and What are the Problem?
16. What do we want to Improve?
Reduction in Accident
Elimination of Pollution
Productivity Improvement
Reduction in number of unplanned failures
Improvement in Equipment Operating Time

Effectiveness of Lean Simulations
Can Simulations be effective? How much? 7VmEe
18. Intangible benefits of Lean Simulations
• After going through the lean simulation the participant
understands his/her role in productivity improvement and take
care of their equipment and processes themselves without
being ordered to.
• With achievement of zero losses, zero downtime and zero
defects the participants get new confidence in their own
abilities
• Workplace safety gets improved and looks neat, clean and
pleasant.
• The organization image gets improved which gets greater
business.

19. We are ready to train our Eyes.
We are ready to train ourselves through Lean
Simulations.

21. What to Measure in a Production System?
In simulation or in any production system there are inputs and
outputs. The inputs are men, machines and materials and the
outputs are quality, cost and delivery.
Input
Men

Machines
Process

Quality
Cost

What to Measure Input, Process or Output (Results) ?
7VmEe
Results
22. We must measure results
QCD (Quality, Cost & Delivery)
Quality - Is the correct quality as specified of the customer( and
no better because of the cost implication)
Cost - Is the right cost for the business, reducing year on year. It is
made up to materials,labour and overhead.
Delivery-is the right quantity, at the right time, to the right
quality, time after time. The customer remembers the last time the
supplier did not deliver. Not all the time delivery was made)
It is vital for any organization to measure how well it is managing
these outputs.
Our lean simulation production system tracks all of these vital measures.
7VmEe
23. The Vital Measures
Our lean simulation covers these vital measures that any
manufacturing/business person must be aware of.
These “vital measures” can be applied to an entire factory, a value
stream, a cell or even one process. They can be used together or
separately to identify where to apply focused efforts (lean
/improvement).
These Vital measures are for measuring Quality ,Cost & Delivery
1. Right First Time (RFT %)
2. Overall Equipment Effectiveness( OEE %)
3. Stock Turns
4. Delivery Schedule Achievement (DSA%)
5. People Productivity (PPOH-Parts Per Operating Hour)
6. Value Added Per Person(VAPP, Rs.)
7. Floor Space Utilization
7VmEe
24. What to Measure in a Production System?
• Various organizations measures many factors to understand
their manufacturing systems and try to improve on the factors.
• Most of them measures downtime, up time, cycle time, overall
equipment efficiency & inventory turns etc.
• Through the lean simulation, we too can learn art of
measurement in Production Systems and will measure them on
the “7 Vital Measures ” which are exhaustive and more
effective.

Measures our ability to control over our manufacturing process, if we are not in
control we need plenty of stock to protect the process against the problems.
If we have high stock turns, we are flowing material quickly through the factory and
less money is tied at shop floor and shorter lead time for our customers.

Can we measure these “7 vitals” in our Areas?
7VmEe
36. How to measure these “7 Vitals” through Lean
Simulation?
Answer lies in “simulated work environment for lean”
7VmEe
37. Let us learn through
“exercise”
Can we create Simulated Environment?
7VmEe
38. Let us Create “simulated work environment-Lean”?
We will plan an exercise where an envelope manufacturing company will be set up.
This company will make paper envelope of given specification and sample and will
supply to Customer in specified quantity and specified time.
This company uses land, raw material, capital equipment, utilities, consumables,
manpower etc. to make envelopes.
This company also hires consultant/professional for identifying and eliminating wastes
and make improvements.
This company has 6 manpower and the persons needs to play role of team member,
team leader, group leader & manager.
Every resource has a cost associated with it .
The 1st round of the simulation lasts for 60 minutes, in which one team needs to deliver
30 good quality envelopes in specified quantity and specified time.
After completion of the 1st round, every team is asked to calculate the 7 vital measures
and present them to other teams.
These teams needs to identify the problem areas and plan for improvements in 2nd
round.
The improvements can be changes in layout, changes in roles, changes in
processes,increasing,decreasing no of work stations etc. etc.
7VmEe
39. Let us Create “simulated work environment-Lean”?
The teams are asked to participate in 2nd round. With an target to improve these 7
vitals at least by 40%
In 2nd round customer again wants 30 envelopes to be delivered in 60 minutes
duration.
In 2nd round customer wants good quality product in specified quantity and at
specified time.
After completion of the 2nd round the teams are asked to
1.calculate these 7 vitals and explain the difference in 1st and 2nd round.
2.Explain 7 type of waste and example in own simulation
3.Explain 3 Kaizens/Improvements they did.
4.Explain importance of Lean.
5.How the same can be standardized.
7VmEe
40. Let us create “simulated work environment-Lean”?
Team Formation
