Karakuri is mean mechanism,
Karakuri kaizen is how to make a improvement especially about ergonomi with a mechanism with less energy (no pneumatic, hydrolic, motor)
Karakuri kaizen which was first introduced by Japanese is system which is used to handle the materials using natural principles like gravitation force, centrifugal force, etc. It requires only initial investment cost and so plans were made to apply this system at the machine shop.
Here is one from Japan’s JMAC with multiple examples:
Such devices have long been used as part of TPS and Lean, but now we have a generic name for them. The principles of Karakuri Kaizen given at the end of this video are as follows:
- Don’t use the human hand. Move objects automatically.
- Don’t spend money.
- Use the force of your equipment.
- Build it with the wisdom and creativity of the people of the shop floor.
- For safety, don’t just rely on paying attention but build a device that stops automatically.

3 Sheets of Standardized Work
January 4, 2016
There are 3 Sheets in standardized work :
1) Standardized work chart (SWC)
2) Standardized work combination table (SWCT)
3) Production capacity sheet (PCS)
Those 3 sheets is interlinked, when we will improve standardized work, so we must make 3 sheets to evaluate current condition before we make improvement. Continue Reading

What is Standardized Work?
Standardized work is one of the most powerful but least used lean tools.
By documenting the current best practice, standardized work forms the
baseline for kaizen or continuous improvement. As the standard is
improved, the new standard becomes the baseline for further
improvements, and so on. Improving standardized work is a never-ending
In my training about Standardized Work, SW means :
Work is a tool to make quality products, based on operator movement,
that is arranged with appropriate sequence without MUDA (non added
Standardized Work’s spirit is a TOOL Continue Reading
