The Toyota Production System (TPS) arose from Toyota's circumstances in the 1950s. Key elements include Just-in-Time production to eliminate waste, standardized work processes, visual management systems, continuous improvement through kaizen, and ensuring quality through jidoka. The overall goals of TPS are to provide high quality products, respect employees, reduce costs through waste elimination, and ensure flexibility. TPS focuses on eliminating waste and respecting people to reduce costs while increasing quality, flexibility, delivery speed and overall customer satisfaction.

5. • The Toyota Production System (TPS) arose out of necessity in response to the
circumstance surrounding the company. Many of the foundational concepts are
old and unique to Toyota while others have their roots in more traditional
sources.
• The oldest part of the production system is the concept of Jidoka which was
created in 1902 by Toyota founder Sakichi Toyota.
• The most famous element of the TPS is no doubt the Just-in-Time pillar of the
production system.
• Everything was expected to be procured just in time and not too early or too
late. Later elements developed in the 1950’s including takt time,standardized
work, kanban, and supermarkets added to the basis for JIT.
• There are also many other tools and techniques that were developed in Toyota
such as 7 Wastes,Standardized Work, 5S, SMED, Visual Control, Error Proofing,
as well as many others.

6. GOALS OF TPS
The goal of the Toyota Production System is to provide products at world class quality
levels to meet the expectations of customers, and to be a model of corporate
responsibility within industry and the surrounding community.
The Toyota Production System historically has had four basic aims that are consistent
with these
values and objectives: The four goals are as follows:
1. Provide world class quality and service to the customer.
2. Develop each employee’s potential, based on mutual respect, trust and
cooperation.
3. Reduce cost through the elimination of waste and maximize profit
4. Develop flexible production standards based on market demand.

GENCHI GENBUTSU
“Going to the source to find
the facts to make correct
decisions, build consensus
and achieve goals.”
11Manufacturing Technology

12. Respect
For People
RESPECT
“Toyota respects others,
makes every effort to
understand others, accepts
responsibility and does its
best to build mutual trust.”
TEAMWORK
“Toyota stimulates personal
and professional growth,
shares opportunities for
development and maximizes
individual and team
performance.”
12Manufacturing Technology

13. How to make money?
Traditional pricing strategy: Cost + Profit = Selling price
Example: When the cost goes up, the product selling price is raised to reflect the
higher costs and maintain the desired level of profit.
Some even argues that the profit added should be large enough to cover potential
losses if the product does not sell well.
Toyota accepts neither this formula nor these
arguments!
13Manufacturing Technology

14. Toyota's philosophy
Selling price – Cost = Profit
Customers decide the selling price.
Profit is what remains after subtracting the cost from it.
The main way to increase profit is to reduce cost.
Consequently, cost reduction through waste elimination should have the highest
priority.
Toyota's paradox: Reducing cost (waste), will reduce lead time while increasing
quality and customer satisfaction.
How? We will discuss it soon.
14Manufacturing Technology

15. Toyota Production System
Definition: The production system developed by Toyota Motor Corporation to provide
best quality, lowest cost, and shortest lead time through the elimination of waste.
The Toyota Production System empowers team members to optimize quality
by constantly improving processes and eliminating unnecessary waste in
natural, human and corporate resources.
It entrusts employees with well-defined responsibilities in each production step
and encourages every team member to strive for overall improvement.

17. Main Pillars Of TPS
• JUST-IN-TIME
• JIDOKA
17Manufacturing Technology

18. • JUST-IN-TIME- smooth, continuous, optimized workflows……………….
• JIT is a manufacturing philosophy involving an integrated set of procedures/activities
designed to achieve a volume of production using minimal inventories
OR
• A philosophy that seeks to eliminate all types of waste, including carrying excessive levels of
inventory and long lead times.
• Takes its name from the idea of replenishing material buffers just when they are needed
and not before or after.
• Best applied to a production system, such as automobile assembly, that would be
considered repetitive, such as a flow shop.
18Manufacturing Technology

19. 19Manufacturing Technology

20. JIT Elements Are:
• Takt Time
• Flow Production
• Pull system
20Manufacturing Technology

21. • TAKT TIME(Heartbeat of production)
• Takt is the rate of customer demand – essentially, what the market is requiring be
produced.
• It is the basis on which we can create flow within our work-cells and throughout
our whole value chain from raw materials to customer delivery.
• Takt time is the available working time for production divided by the actual average
daily demand for our product(s) expressed in minutes. this gives us the customer
demand rate for use throughout our organization and the supply chain.
• The Takt time also forms the basis for enabling the design and balancing of our
work-cells and production lines in an efficient manner.
21Manufacturing Technology

22. 22Manufacturing Technology

23. Takt Time vs Cycle Time
• Takt time should not be confused with machine cycle time; machine cycle time is the
time taken to produce a part, this could exceed takt time in some cases which would
mean that the process would be incapable of producing enough products within the
available time.
• Where cycle times exceed your Takt time there is a need for machines to either be
run on additional shifts to build stock, the product to be outsourced or a need for
additional machines to be run in parallel.
23Manufacturing Technology

24. FLOW PRODUCTION
• Producing and moving one item at a time (or a small and consistent batch of
items) through a series of processing steps as continuously as possible, with each
step making just what is requested by the next step.
It is also called the one-piece flow, single-piece flow, and make one,
move one.

27. PUSH vs PULL SYSTEM
• Push system : material is pushed into downstream workstations regardless
of whether resources are available
• Pull system: material is pulled to a workstation just as it is needed

30. HEIJUNKA – LEVELLING THE FLOW
• The term heijunka describes the foundation of the TPS approach.
are produced, often significantly unrelated to demand.
• With heijunka a process is designed to switch products easily, producing what is
needed when it is needed, and relying on production.
• Any variations in volumes are accommodated by establishing a level-average demand
rate.
• It will reduce the ripple effect of the production.

38. KANBAN CARD
• A smooth, continuous and optimized workflow, with carefully planned and measured
work-cycle times and on-demand movement of goods, reduces the cost of
wasted time, materials and capacity.
• Team members can concentrate on their tasks without interruption, which leads to better
quality, timely delivery, and peace-of-mind for Toyota’s customers.
• In TPS it means having just the right components to build the product.
38Manufacturing Technology

39. • JIDOKA……. building in quality
Jidoka translates as “automation” and can
be described as
“automation with a human touch”.
If a defect or error is
identified it is addressed immediately –
even if this means
temporarily stopping production.
39Manufacturing Technology

40. • GENCHI GENBUTSU – GOING TO THE SOURCE
• It means going to the actual place to solve the problem.
• which means ‘going to the source’ of the problem and assessing it for yourself rather
than relying on information supplied by others, in order to gain a complete and
accurate understanding.
40Manufacturing Technology

41. ANDON BOARD/WHEEL
• The Andon board is a simple but highly-visible electronic sign displaying the status of
production lines.
• It notifies management immediately if a worker has identified a fault, precisely
identifying its location.
• Workers take responsibility for production quality, with the power to stop the
production line as required.
• The production line will not be restarted until the
reason for the fault has been resolved.
41Manufacturing Technology

42. STANDARDISATION
• key element for quality assurance is a focus on standardization.
• Developing and relying on standardized work tasks not only ensures
consistently high levels of quality, but also maintains production pace and
provides a benchmark for implementing continuous improvement.
42Manufacturing Technology

43. • MISTAKE-PROOFING AND LABELLING
Devices that make it difficult or impossible for a worker to make
typical errors at his or her workstation are a common sight on
Toyota production lines.
Goal: Finding defects
before they occur
= Zero Defects
43Manufacturing Technology

44. • VISUAL MANAGEMENT
• In shop floor the things are visually display so that every one can excess them.
• Provide safety features for employs like by visually representing the Heights, how to
carry load, how to move pallet truck etc.
• Help's visitor to excess plan without the help of others.
• It also applies for tools,materials,documents etc.
