Lean 0 comments. To obtain Lean within an organization, it is necessary to make use of different methodologies suited to your organization.

These methodologies provide actionable steps to change the thinking and processes of your organization. Kaizen and Kaikaku are two of these methodologies, both related to the improvements within a business when implementing lean processes. When people enter the world of lean processing and methodologies, Kaizen is usually the first one they may think of, or be advised about.

However, the deeper you move into Lean the more you learn, and in particular the term Kaikaku. Although they are similar methods, there are differences in the way they work, and how they are implemented. Translated from Japanese Kai means change, and Zen means for the better, Kaizen is an evolutionary methodology.

Kaizen is the familiar kind of improvements used when it comes to Lean; it involves taking your time and effort to work through current processes. Kaizen then requires an organization to implement incremental changes to action improvement. When applied within a workforce it involves everyone, from managers to floor staff, every day and every location. Kaizen provides a structure of continuous improvement that is constantly used within an organization with minimal risk, yet producing effective results.

In contrast to Kaizen, Kaikaku is a revolutionary method and is for those moments when part of implementing Lean requires the need for a more radical step change. When a problem arises that requires immediate more effective change, usually for a larger project, Kaikaku comes into play.

This can be the installation of a software update that will have a large impact on the processes within an organization, quickly reducing waste within the step s it is associated with. The results are more immediate, yet the risk is far greater than Kaizen.

The main identifiable differences between Kaizen and Kaikaku are the size of the action taken to achieve lean, and the length of time it takes for that action to have a noticeable effect. Summarizing, Kaizen has a continuous incremental impact , while kaizen has a more radical, immediate impact. However, this does not mean you need to only select one or the other.

In actual fact, Kaizen and Kaikaku work well when coupled together in synergy. Kaikaku is often used as a precursor to implementing Kaizen in many organizations. Think back to the example of installing new software, Kaikaku is the installation of the software, while the staff training for that software, and their continuous use of it is Kaizen. Sometimes if you do not get the desired results from Kaikaku, it can take the use of continuous improvements to actually see those results become a reality.

Both improvements do require a group of individuals who are vested, and believe in the organization that they are trying to improve in order to be successful. Your email address will not be published. Submit a Comment Cancel reply Your email address will not be published.


The Difference Between Kaizen and Kaikaku

Two of the most powerful are: Kaikaku and Kaizen. Kaikaku and Kaizen are both ways to approach Lean Manufacturing. While they are both important, they are also fundamentally different. Kaizen is often described as continuous improvement. There is some convincing evidence that this word has lost some of its original Japanese meaning and power when applied in the western way, but it is still highly useful nonetheless. Kaizen is often used to describe the smaller steps taken as part of the overall lean journey. With everything flowing more smoothly, workers take notice and get behind your efforts.


Kaizen vs. Kaikaku

Radical, revolutionary improvement of a value stream to quickly create more value with less waste; sometimes called kakushin. One example would be moving equipment over a weekend so that products formerly fabricated and assembled in batches in isolated process villages are made in single-piece flow in a compact cell. Another example would be quickly switching from stationary to moving assembly for a large product such as a commercial airliner. Also called breakthrough kaizen, in comparison with more gradual, step-by-step kaizen.


Kaikaku is a philosophy more focused on the improvement of production through radical changes in the way of operating, ie reduce implementation time to increase the impact, this methodology as Kaizen has its origin in Toyota. Kaikaku comes from the Japanese radical change in a very specific and short period of time. It seeks to generate a change of great impact throughout the organizational pyramid, give a new approach to the way of working, the objectives, technology used, this methodology is used when the company enters a valley where there is no improvement and makes use of other methodologies that do not give the expected performance, in many occasions you will find this philosophy as Kaizen Blitz. The DNA of kaikaku is innovation, because its purpose is to change the way of doing things in a short time, in a transformation rather than technical, human; promoting participation, risks, openness; with the support of teams with vision to propose new things, and open leaders, promoters. Be a short or long term strategy, with immediate impact or progressive results over time; The truth is that, beyond equipment and resources, organizations must enrich their processes with philosophies that define a clear horizon of action; a philosophy that transcends the technical and methodological, and permeate institutional and individual actions. There are many ways to achieve this radical leap in practice.
