Jidoka / Hanedashi

Short Description

Referring to the origin of the Toyota Production System, Jidoka is one of the foundations of Lean Production. It stands for simple autonomation, forcing things to happen as they should – autonomously. Without having to give further instructions. It also refers to machines to have just one particular function without anything going wrong. The Hanedashi lifts those machines to the next level by giving machines the functionality of just being loaded, no unloading of parts and starting necessary.


Why do you have to use Jidoka / Hanedashi?

Decrease in Maintenance Costs

When using the approach of autonomation, you have to apply it on everything you do inside your factory: Your operators have to be trained accordingly, your processes have to be designed in a way which allows you the approach of autonomation and your equipment has to be adapted to that principle. When following that principle, all processes and equipment will maintain itself in a certain way as you avoid unpredictable circumstances ahead. Far less maintenance activities will be needed inside your factory.

Decrease of Manual Handling Processes

When equipment acts autonomous without the operator paying too much attention for, he can focus on value-adding activities instead. The Hanedashi allows machines to eject processed parts automatically. For that reason, the operator will be unloaded from unnecessary walking and material handling.

Increase in Quality

Jidoka originated from Mr. Toyoda, the founder of Toyota at a time, when Toyota was producing looms. When the strand ripped, the automatic loom had to stop immediately. For that reason, Mr. Toyoda developed simple solutions, to prevent the machines from producing scrap parts. Since then, that sense of autonomation was applied throughout the entire industry.
