Overview: What is Datsu Chaku?

Datsu Chaku is a Japanese term that means Unload – Load. It is primarily used in manufacturing to describe performing a task. It is in reference to the traditional way of loading components on a machine.

Drawbacks of Datsu Chaku

There are significant drawbacks to the traditional Datsu Chaku method that should be understood:

Time waste

By having to stop to unload a part, there is significant time wasted in a process.

Movement waste

By having to physically unload a part, there is the unnecessary movement for employees that could be avoided if a machine did this automatically. Over time, this unnecessary movement could contribute to employee fatigue or even injury.

Outdated –

Datsu Chaku is a method that is generally outdated since it has been significantly improved upon with Chaku Chaku.

Why is Datsu Chaku Important to Understand?

Datsu Chaku is important to understand for the following reasons:


Having to load/unload is not the most efficient method. By understanding this, you have the opportunity to find better methods to improve the manufacturing processes within your organization.

Saving money

By understanding how time is wasted with the traditional load/unload methodology, you can look into rectifying the lack of efficiency in a process. By improving the process, you will be able to manufacture the same number of units in likely a shorter amount of time. This frees up time to make more units, thereby increasing the potential for profit, or open up the ability for employees to move on to other tasks.

Happy workers

Understanding this concept means that you have the knowledge of where your manufacturing process can be improved. By figuring out how to eliminate a step from the manufacturing process, you can help make your employees’ jobs easier, which makes for happier workers.

An industry example of Datsu Chaku

A new floor manager is hired to oversee a manufacturing plant. On their first day, ownership asks them to take notes about any improvements that could be made in their manufacturing processes. While walking the manufacturing floor, the floor manager notices that a worker has to load/unload parts manually and then move them to another station several yards away for the next part of the manufacturing process. With the employees moving from distant station to station, the new floor manager sees a lot of wasted time and movement that could be eliminated. They recommend moving from this traditional Datsu Chaku method to having the work area be set up so that an employee can easily move from station to station just by taking a step of two. Once one part of a process is complete, an employee can quickly and simply move on to the next. Once tested, the manufacturing plant decides to implement this Chaku Chaku method.

3 best practices when thinking about Datsu Chaku

Here are some of the best practices to keep in mind when it comes to Datsu Chaku:

1. Not the most efficient method

If you are working with the traditional Datsu/Chaku method, it should be kept in mind that this is likely not the most effective manufacturing method.

2. Price

While the cost of switching from a Datsu Chaku method to a Chaku Chaku method may be more costly at the onset, it is worth looking at how much it can save you over the long-term.

3. Look at all available options

Before making the change from Datsu Chaku to another method, be sure to assess and analyze all available options before making the change.

Frequently Asked Questions (FAQ) about Datsu Chaku

What is the difference between Chaku Chaku and Datsu Chaku?

Datsu Chaku is the traditional method of component loading, loading and unloading, moving from station to station, etc. Chaku Chaku is a vast improvement over this method. Chaku Chaku strives for continuous improvement by a focus on automation and having stations that are part of steps in a process as close together as possible in order to maintain flow and maximize efficiency.

Is Chaku Chaku better than Datsu Chaku?

A focus on Chaku Chaku in an organization is a major improvement over the traditional Datsu Chaku.

Will implementing Chaku Chaku over Datsu Chaku cost a lot?

It can depend on exactly what part of the methodology you are choosing to focus on in your organization. If you are merely wanting to make the shortest distance possible between stations needed in the development of a product, there is little to no cost involved. If it involves the purchase of specialized machinery, it could mean significant costs will be involved.

Phasing out Datsu Chaku from your workplace

If your employees are spending too much time moving from one step in a process to the next due to the distance between steps, it is important to move away from the traditional Datsu Chaku method and towards the Chaku Chaku method. Working towards having your processes run smoothly with as little downtime as possible should be a goal of any business.
