A machine shut down for repair is not making parts that could make money. But TPS has challenged this notion.

Often the best thing you can do is to idle a machine and stop producing parts. Over production, is a fundamental waste in TPS. Often it is best to build up an inventory of finished goods in order to level out the production schedule, rather than produce according to the actual fluctuating demand of customer orders. Leveling out the schedule heijunka is a foundation for flow and pull systems and for minimizing inventory in the supply chain. Leveling production smoothes out the volume and mix of items produced so there is little variation in production from day to days.

Often it is best to selectively add and substitute overhead for direct labor. When waste is stripped away from value-adding workers, high-quality support has to be provided for. The manual process must be streamlined before it is automated.

Among his inventions was a special mechanism to automatically stop a loom whenever a thread broke. Just-In-Time was his son Kiichiro Toyoda's contribution.

It is best to selectively use information technology and often better to use manual processes even when. This invention led to the concept of jidoka automation with a human touch. His ideas were influenced by a study trip to Ford's plants in Michigan to see the automobile industry Kiichiro was also inspired by the U.

Toyota staffs sales. Many U. To relieve them of this punishing labor. Working faster just for the sake of getting the most out of workers may be counter productive. When Toyota sets up assembly lines. TPS is all about commitment to continuously investing in its people and promoting a culture of continuous improvement. Toyoda eventually developed sophisticated automatic power looms. They do not understand the power behind true TPS.

Companies should produce at the rate of customer demand. TPS starts with the customer. If Sakichi Toyoda put his mark on the industrial world through loom making. Toyoda learned carpentry from his father and started designing and building wooden spinning machines. In he began to make manual looms that were cheaper and more efficient than existing looms. As a boy.

It may not be a top priority to keep your workers busy making parts as fast as possible. Toyota is a true learning organization that has been evolving and learning for most part of a century. People are the most flexible resource. Bigger rivals like Ford had tons of cash and a large U. It needed to adapt Ford's manufacturing process to achieve simultaneously high quality. Toyota had no cash and operated in a small country.

Toyota has identified various types of non-value-adding waste: Producing items for which there are no orders. Toyota needed to turn cash around quickly. Toyota had realized that the Japanese market was too small and demand too fragmented to support the high production volumes in the U.

Toyota did not. Kiichiro had to ask for 1. Through the customer's eyes. Even before the second world war. But rampant inflation made money worthless and collections became very difficult. This led to work stoppages and public demonstrations by workers. This "work in process" must then be stored and tracked and maintained until needed by step 2. Toyota needed to churn out low volumes of different models using the same assembly line.

This creates "pull" which continues cascading backwards to the beginning of the manufacturing cycle. Ford had a complete supply system. Toyota realized that to survive in the long run. Many workers voluntarily left the company and labor peace was restored. Kiichiro accepted responsibility for the failure and resigned as president. Identifying waste The first question in TPS is always" What does the customer want from this process? Toyota adopted strict cost-cutting policies.

As the cash crunch worsened. With few resources and capital. Toyota didn't have the luxury of taking cover under high volume and economies of scale afforded by Ford's mass production system. As the economy gained momentum. Toyota had little difficulty getting orders for automobiles. Most businesses use processes that are filled with waste. This leads to overstaffing and storage and transportation costs.

TPS is a "pull system". Excess inventory. This reinforces jidoka. Big buffers lead to other suboptimal behavior. The requirement for working with little inventory and stopping production when there is a problem. Using smaller buffers means that problems like quality defects become immediately visible.

Unused employee creativity. Unnecessary transport or conveyance. Unnecessary movement. Any wasted motion employees have to perform during the course of their work.

Excess inventory hides problems such as production imbalances. Toyota firmly believes overproduction is a fundamental waste. In mass production. The maintenance department fixes the problem while inventory keeps the operations running.

Workers merely serving to watch an automated machine or having to stand around waiting for the next processing step. Producing more than what the customer wants necessarily leads to a build-up of inventory somewhere downstream.

Workers must resolve the problems immediately to resume production. The material is just sitting around. By contrast. Inefficient processing due to poor tool and product design. Waiting time on hand. Walking is also waste.

14 Management Principles of The Toyota Way

Production of defective parts or correction. Why worry about preventive maintenance on equipment when shutdowns do not immediately affect final assembly anyway?

Why get overly concerned about a few quality errors when defective parts can be set aside? By the time a defective piece works its way to the later operation where an operator tries to assemble that piece.

Repair or rework. Overprocessing or incorrect processing. Waste is also generated when providing higher-quality products than is necessary. Losing time. Carrying work in process WIP long distances. JIT means removing. Principle 7. To facilitate the discussions. Level out the workload heijunka. Use visual control so no problems are hidden.

Respect your extended network of partners and suppliers by challenging them and helping them improve Principle With the Prius. Make decisions slowly by consensus. Principle 9. Principle 8. Become a learning organization through relentless reflection hansei and continuous improvement kaizen. Principle Build a culture of stopping to fix problems.

Principle 2.

Create continuous process flow to bring problems to the surface. Go and see for yourself to thoroughly understand the situation genchi genbutsu. Jeffrey K Liker. Principle 3. Principle 4. Principle 5. Develop exceptional people and teams who follow your company's philosophy. Principle 6. Base your management decisions on a long-term philosophy. In Toyota's traditional approach. Use only reliable. So people have to scramble to fix problems together to get the equipment up and running.

Use "pull" systems to avoid overproduction. Standardized tasks are the foundation for continuous improvement and employee empowerment. Grow leaders who thoroughly understand the work. But the Prius project intensified it. There is more teamwork. Towards one piece flow To become lean. There was unparalleled cooperation across divisions and between design and manufacturing to meet the tight headlines for the Prius. By then it is nearly impossible to track down and identify why the defect occurred.

Traditional business processes. Creating flow exposes inefficiencies that demand immediate solutions. Flow also tends to force the implementation of a lot of the other lean tools and philosophies such as preventive maintenance. By making a product flow.

In a large batch operation. If we dedicate equipment to a product line. This level of cooperation at such an early stage is unusual in the auto industry. Manufacturing engineers now work with design engineers at the concept development stage. But if defects do get missed and passed on. Creating flow means linking together operations that otherwise are disjointed.

Shortening the elapsed time from raw materials to finished goods or services leads to the best quality. Simultaneous engineering.

In lean thinking. Real Flexibility.

14 Management Principles from the World's Greatest Manufacturer

Every operator is an inspector and works to fix any problems in station before passing them on. Flow means that a customer order triggers the process of obtaining the raw materials needed just for that customer's order. But if the lead time to make a product is very short. It is much easier to build in quality in one-piece flow. The raw materials then flow immediately to supplier plants.

Everyone concerned is motivated to fix the problems and inefficiencies because the plant will shut down if they don't. Toyota had been incorporating simultaneous engineering for several years before the Prius. Instead of putting a new order into the system and waiting weeks to get that product out. The whole process should take a few hours or days. Accommodating changes in customer demand can be done almost immediately. Lean manufacturing dramatically increases the importance of building things right the first time.

It is easy to calculate the value- added work and then figure out how many people are needed to reach a certain production rate. Toyota does not build products according to the actual flow of customer orders.

Andon refers to the light signal for help. The last thing management in traditional mass manufacturing allows is a halt in production.

The reason it appears that productivity is highest when operation is organized by department is because each department is measured by equipment utilization and people utilization.

With very low levels of inventory. Bad parts are simply labeled and set aside to be repaired at another time and by another department. Much time is also lost tracking down defective parts and components and repairing finished products?

In a one-piece-flow cell. Where demand fluctuates significantly.

The mantra is to produce large quantities at all costs and fix problems later. Much productivity is lost when people are "utilized" to overproduce parts. In-station quality preventing problems from being passed down the line is much more effective and less costly than inspecting and repairing quality problems after the fact.

The total volume of orders in a period is levelled out so the same amount and mix are being made each day. When equipment shuts down. Problems in operation A will quickly shut down operation B. But the small inventory protects the production schedule from being upset by sudden spikes in demand.

Jidoka is also referred to as autonomation — equipment endowed with human intelligence to stop itself when it has a problem. Heijunka Heijunka is the leveling of production by both volume and product mix. Toyota will often keep at least a small inventory of finished goods. By living with the waste of some finished goods inventory.

But it is hard to determine how many people are needed to produce a certain number of units in a large batch operation because productivity is not measured in terms of value-added work. This seems to contradict lean thinking. The Toyota Way emphasises stopping or slowing down to get quality right the first time to enhance productivity in the long run.

Unlike Taylorism. A common Toyota quality tactic is to anticipate problems as early as possible and put in place countermeasures before the problems even occur.

Toyota keeps things simple and uses very few complex statistical tools. Standardisation does not necessarily imply a bureaucratic approach. In the workplace. A coercive bureaucracy uses standards to control people.

The quality specialists and team members have just four key tools: Andon works only when employees know the importance of bringing problems to the surface. Workers follow very detailed standardized procedures that touch every aspect of the organization.. Occasionally a time-out is required to reflect on the purpose and direction of the project before moving on.

One must standardize. If the process is shifting. Quality planning depart- ments are armed with reams of data analyzed using the most sophisticated statistical analysis methods. There is strict discipline about time. Toyota prefers to first use people and processes to solve problems. Unless there is a problem-solving process already in place and people are following it.

But Toyota follows a different approach. Things like IS Standardisation Toyota believes standardized work is the basis for empowering workers and innovation in the work place. But Toyota also values many of the characteristics associated with flexible organizations referred to as "organic": Six Sigma black belts attack major quality problems with a vengeance. The standards actually help people control their own work.

Sort-Sort through items and keep only what is needed while disposing of what is not. Toyota will then use a pilot area to improve the process with the existing equipment.

These include principles of valuing people over technology. Toyota will go to great lengths to analyze the impact it may have on existing processes. Shine cleanliness. Toyota will reject the technology or at least delay adopting it until the problems are resolved. Imposed rules that are strictly policed become coercive and a source of friction and resistance between management and workers.

It will look for new opportunities to eliminate waste and even out the flow. Nobody likes rules and procedures when they are imposed on them. A place for everything and everything in its place. Before introducing new technology.

Technology Toyota introduces new technology only after it is proven through direct experimentation with the involvement of a broad cross-section of people.

This means the technology should be highly visual and intuitive used right. The technology is then carefully analyzed to see if it conflicts with Toyota's philosophies and operating principles. The 5S The five Ss seiri. When it has accomplished as much improvement as possible with the present process. If the new technology is acceptable. The cleaning process often acts as a form of inspection that exposes abnormal and pre- failure conditions that could hurt quality or cause machine failure.

Toyota will ask again if it can make any additional improvements by adding the new technology. The key to achieving this balance lies in the way people write standards as well as who contributes to them. If the technology violates these principles or if there is any chance of disrupting stability. Someone trained in the Toyota Way. A critical element of the culture is genchi genbutsu.

But a decision that works out well. Leaders must demonstrate this ability and understand how work gets done at a shop floor level.Principle 6. Throughout this analysis and planning, Toyota will broadly involve all key stakeholders in a consensus-building process. It needed to adapt Ford's manufacturing process to achieve simultaneously high quality. His ideas were influenced by a study trip to Ford's plants in Michigan to see the automobile industry Kiichiro was also inspired by the U.

A learning organization When processes are stable and waste and inefficiencies become publicly visible. The most intensive effort has been in North America.
