What is Jidoka in quality?

Definition of Jidoka By definition, Jidoka is a Lean method that is widely adopted in manufacturing and product development. Also known as autonomation, it is a simple way of protecting your company from delivering products of low quality or defects to your customers while trying to keep up your takt time.

What is an example of Jidoka?

One famous example of jidoka is the Toyoda Automatic Loom Type G, invented and patented in 1925 by Sakichi Toyoda (1867–1930). This was one of many looms invented by this King of Inventors, but it is probably his most famous one. The loom was also able to detect problems and could shut down.

What is another word to describe the principle of Jidoka?

Autonomation describes a feature of machine design to effect the principle of jidoka (自働化)（じどうか jidouka), used in the Toyota Production System (TPS) and lean manufacturing. It may be described as “intelligent automation” or “automation with a human touch”.

What does Jidoka mean in a Toyota production system?

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 are the benefits of using Jidoka?

The advantage of Jidoka is workers can monitor multiple work stations more frequently (reducing labor costs) and many quality issues can be detected immediately with the implementation of Jidoka. This way defects can be identified and caught early and workers don’t have to rely heavily on final inspection or testing.

How does Jidoka work?

Jidoka highlights the causes of problems because work stops immediately when a problem first occurs. This leads to improvements in the processes that build in quality by eliminating the root causes of defects. Jidoka sometimes is called autonomation, meaning automation with human intelligence.

What is Jidoka in supply chain management?

The Jidoka principle describes the ability of a machine, a plant or an entire system to switch itself off in case of errors, quality and production problems. Via sensors, limit switches or other devices, malfunctions or occurring errors are detected, which leads to the above-mentioned automatic shutdown of the machine.

What are the two constituents of jidoka?

Principles of Jidoka

• Discover an abnormality.
• STOP.
• Fix the immediate problem.
• Investigate and correct root cause.

Where is jidoka used?

lean manufacturing
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.

How is Jidoka implemented?

We can define jidoka as a four-step process that engages when abnormalities occur.

1. Detect the abnormality.
2. Stop.
3. Fix or correct the immediate condition.
4. Investigate the root cause and install a countermeasure.
