What is Jidoka?
Because the character for “human being” has been added to the standard spelling, its meaning has changed. Therefore, the definition of Jidoka can be best understood as “autonomation” meaning automation with a human touch, or autonomous automation.
What is the difference between autonomation and Jidoka?
In case of autonomation, if the previous piece has not been picked up during ejection, the machine gives a signal or stops the cycle all together. Jidoka can be simply defined as ‘humanized automation’. Autonomation is just another term for Jidoka. It is used in different contexts.
What is the Jidoka lean process?
Jidoka remains part of the Lean process for many companies. It promotes the active involvement of every employee, no matter their position and job title. Jidoka ranks with the top practical Lean tools and concepts that can work not only on the manufacturing floor, but in all types of processes.
What is a Jidoka loom?
The automatic loom, invented by Sakichi Toyoda, the founder of Toyota, in the year 1902, can be considered as the first Jidoka example. In this innovation, if threads ran out or broke, the loom process was stopped automatically and immediately. In the early days of assembly line mass production, work cycles were watched over by a human operators.
What is an example of Jidoka?
A simple example of how jidoka works can be found in a printer. Your printer is designed to stop automatically if the toner (or ink) is low. If the printer didn't stop automatically, you would waste paper or print a large document where the first pages are good, but subsequent pages would decrease in quality.
Who uses Jidoka?
Jidoka is a term commonly used in lean manufacturing, and widely considered one of the pillars of the Toyota Production System, the other being Just in Time (JIT). However, while the word jidoka is often used to impress others, the ideas behind it are much less frequently found outside of Toyota.
Why is Jidoka important?
Jidoka is important because it ensures products are made with high levels of quality because defects are automatically detected throughout the process.
What is Jidoka and just in time?
The Toyota Production System (TPS) was established based on two concepts: "jidoka" (which can be loosely translated as "automation with a human touch"), as when a problem occurs, the equipment stops immediately, preventing defective products from being produced; and the "Just-in-Time" concept, in which each process ...

What Is Jidoka?
It may be an automatic stop of the process in case of irregularities, multi-machine handling with semi-automated machines, partial automation, or the automation of dangerous, demanding, and dirty work. (Many thanks to Michel Baudin and his book Working with Machines for the list.)
What is the main point of Jidoka?
In summary, the main point of jidoka for me is to stop the process if there are abnormalities, and then get your process back under control. Optionally, you may try to prevent the issue from happening ever again if possible. Also note that the stop is only done to prevent bigger problems downstream and also to highlight the issue, making it more likely to be fixed!
What is jidoka in Toyota?

What does Toyota mean by kanji?
化 for the action of making something. Toyota did a play on words by changing the middle kanji from 動 to 働. The new kanji means work or labor. This kanji has two more strokes on the left, a so-called radical, which represents 人 for human or person.
Why is it important to stop Jidoka?
Hence, for jidoka it is very important to have an automatic stop for any kind of abnormality, from quality problems to machine issues to running out of material. If the machine would continue with this abnormality, the costs down the line would multiply.
Does Jidoka stop?
Stopping the process is the key of jidoka. However, it does not stop there. Naturally, after the process stops, there should be a focus on getting it going again properly. Hence, the problem at hand needs to be resolved. If it is a quality issue, fix it. If the machine has problems, maybe do maintenance.
What is Jidoka in Toyota?
Jidoka is one of the two pillars of the Toyota Production System along with just-in-time.
When was Jidoka invented?
The concept of jidoka originated in the early 1900s when Sakichi Toyoda, founder of the Toyota Group, invented a textile loom that stopped automatically when any thread broke. Previously, if a thread broke the loom would churn out mounds of defective fabric, so each machine needed to be watched by an operator. Toyoda’s innovation let one operator control many machines. In Japanese, jidoka is a Toyota-created word pronounced exactly the same (and written in kanji almost the same) as the Japanese word for automation, but with the added connotations of humanistic and creating value.
Why is Jidoka called autonomation?
This is because it gives equipment the ability to distinguish good parts from bad autonomously, without being monitored by an operator. This eliminates the need for operators to continuously watch machines and leads in turn to large productivity gains because one operator can handle several machines, often termed multiprocess handling.
What is Jidoka in manufacturing?
On a modern manufacturing floor, Jidoka involves self-monitoring machinery that automatically detects an issue and safely stops. Employees can then conduct an inspection and make the necessary adjustments and changes. A board displays information about the shutdown for everyone to see, communicating what is happening and allowing employees to keep working in other areas, maintaining productivity.
Why use Jidoka?
Using Jidoka gives the people most qualified to fix a problem the authority to do so. It also eliminates the need for managers to hover around every task being performed. It’s an effective combination of innovative technology and human intelligence. Toyota places an emphasis on the human factor.
What are the steps of Jidoka?
These steps include the following. A worker detects an abnormality in a process, resulting in a deviation from the usual workflow. The process is immediately stopped.
What is Jidoka loom?
Today, Jidoka describes a process in which a worker who spots a problem in a process has the authority to stop production and correct the problem. This can occur at any stage of an operation.
Who invented the Jidoka loom?
Toyota created Jidoka as one of the two pillars of TPS (the other is Just-in-Time Production ). The concept started in the early 1900s by Sakichi Toyoda, founder of the Toyota Group, who invented a loom that stopped automatically when the thread broke, according to the Lean Enterprise Institute.
What is Jidoka?
Jidoka, also known as autonomation, is a Lean manufacturing method that emphasizes quality control. It is based on the idea of stopping the production line as soon as a defect is detected.
Brief History of Jidoka
Jidoka was first developed by Sakichi Toyoda, the founder of the Toyota Group. He came up with the idea while working on a loom that would automatically stop when it detected a problem.
How does Jidoka Work?
Jidoka relies on automation to stop the production line as soon as a defect is detected. Stopping the line can avoid producing large quantities of defective products.
