What is Hoshin?

Hoshin is a method used to eliminate waste in processes and improve them by maximizing added value.

The name of the method itself comes from Japan and means:

Ho – direction, goal

Shin – way, determination, compass

Hoshin – the way to the goal

Another, but also very popular name for this method is Kaizen Biltz. We can literally translate Kaizen Biltz as “instant improvement.”

Where is the Hoshin method used?

This method is successfully used in manufacturing companies, regardless of industry. In particular, in organizations that have high-volume production and their processes consist of a large number of operations and production nests.

This does not mean that Hoshin is a method reserved only for manufacturing. It is possible to use this method in service organizations as well. However, then the procedure for implementing Hoshin is not implemented in its entirety.

Hoshin implementation

The implementation of the method is based on a certain procedure to follow. This procedure consists of 8 points. They are:

1. Identify the purpose of mapping and define the team,
2. Conduct process observation, i.e. process mapping,
3. Eliminate waste,
4. Re-measure cycle times,
5. Determine the customer’s Takt Time,
6. Calculate the number of operators,
7. Prepare line balance,
8. Prepare operational instructions and update FMEA.

The complexity of Hoshin implementation depends on the length of the process, the number of operations and the link between operations. The more complicated the process, the more difficult it is to go through the entire implementation procedure.

Example of using Kaizen Biltz

One example of using the Hoshin method is layout changes in the workshop area. These usually involve moving toward One-Piece-Flow by bringing production nests closer together and reducing unnecessary inter-process buffers.

Another common example is changes in operation times. They result from the need to balance jobs. These changes improve efficiency and productivity with unchanged labor intensity.

Sometimes quite simple changes can have spectacular results and an actual “Kaizen Biltz” effect.

Benefits of using the Hoshin method:

• Increased productivity,
• Reduction of inter-operational inventories,
• Reduction of overloads at production stations,
• Identification of bottlenecks in the process and their elimination.
