What is Kaizen?

Kaizen is a Japanese word made out of two words. Kai and Zen. Kai means change and Zen means for the better.

Kaizen is core to the concept of lean manufacturing and helps reduce 7 types of waste, through the concept of continuous improvement.

Kaizen stands on the concept of participation. It increments the role of the process owner and involves encouraging process owners to take small improvement actions, leading to continuous improvement.

The following quote from the founder of Kaizen Institute presents the definition of Kaizen in the simplest form.

“KAIZEN means continuing improvement involving everyone – managers and workers alike.”

Masaaki Imai

It’s a  proactive approach to achieving regular, incremental improvements to the manufacturing process. In a sense, it combines the collective talents within a company to create a powerful engine for improvement.

What if I ask you to improve 0.01% every day for the next year. It would seem to be an insignificant act at the start. But if you keep on doing it for one year on a consistent basis, you would be 38 times a better version of your current self at the end of the year. Isn’t it amazing?

The same is true for Kaizen’s small improvement activities, which seem insignificant at the start but the benefits are immense.

Let’s dig deeper!

Types of Kaizen

Following are the types of Kaizen :

#1 Point Kaizen

There are many different ways to implement kaizen in your business, and one of the most effective is through “point kaizen.”

Point kaizen is a process where small teams of employees are focused on solving a specific problem or improving a specific process. The goal is to make incremental improvements that will add up over time.

This entails improving a point in the value stream, For example :

1. Machine Change over
2. Material Handling
3. Ergonomics

Point kaizen is an effective way to solve problems because it taps into the collective wisdom of the team. By involving everyone in the process, you’re more likely to come up with a successful solution. And by tracking the results, you can be sure that the solutions you implement are actually making a difference.

Every member of the organization has to participate in the Kaizen process at different stages for optimal implementation of the Kaizen Process. But it is not necessary that every member should get involved for each type of kaizen.

For example, Vice President getting involved in Point Kaizen is not such an optimal process.

#2 Flow Kaizen

Flow kaizen is a type of kaizen that is focused on improving the flow of work. The goal is to make sure that work moves smoothly from one step to the next, without any unnecessary delays or interruptions.

Flow kaizen is an effective way to improve the flow of work because it helps businesses identify bottlenecks and other issues that are causing delays. By taking small steps and involving everyone in the process, kaizen can lead to big improvements over time.

This entails several point kaizens leading to improvement in the overall flow. We can say it is the sum of multiple point kaizens. It is oriented to the flow of material/ information.

Example- Re-organization of the production line.

#3 System Kaizen

System Kaizen involves a complete overhaul of the value stream for a particular system of organization. Typical system Kaizen focuses on Man, Machine, Material Systems, or core business processes such as budgeting.

The goal is to make sure that all aspects of the system are working together smoothly and efficiently.

System kaizen is an effective way to improve the overall system because it helps businesses identify and correct problems before they become serious.

For the implementation of each type of kaizen teams are typically made up of 5-10 people, and they meet for a few hours each week to work on their project. The team leader is responsible for keeping the team focused and on track. Each team member brings their own ideas and expertise to the table, and together they brainstorm solutions to the problem at hand.

Once the team comes up with a solution, they implement it and then track the results. If the solution is successful, it becomes a permanent part of the process. If not, the team goes back to the drawing board and comes up with a new solution.

How does Kaizen work?

Kaizen is a Japanese word that means “improvement.” It is a philosophy or mindset for continuous improvement in all aspects of life. Kaizen is based on the idea that small changes made over time can result in big improvements.

In business, kaizen is often used as a way to improve productivity and quality. Many companies use Kaizen principles to help employees think creatively about ways to improve their work.

Kaizen can be applied to any area of life, but it is most commonly used in businesses. In a business setting, kaizen principles are often used to improve quality, productivity, and customer satisfaction. Kaizen can be used to improve any process, from manufacturing to office work.

The key to kaizen is taking small steps, or kaizen baby steps, to make gradual improvements over time. kaizen is about making permanent changes in your behavior, rather than temporary changes that you will eventually revert back to.

When you’re trying to make a change in your life, it’s easy to get overwhelmed and give up before you’ve even really started. This is where kaizen can help. By breaking down your goals into small, manageable steps, kaizen makes it more likely that you’ll stick with your plan and achieve your goals.

For example, let’s say you want to start exercising more. Rather than setting a goal of working out for two hours every day, which is probably not realistic or sustainable, you could set a kaizen goal of walking for 10 minutes every day.

This small goal is much more achievable, and it’s also something that you can build on overtime. Once you’ve made walking a daily habit, you can gradually increase the intensity and duration of your workouts.

But Kaizen isn’t just about achieving your goals; it’s also about improving your process along the way. As you’re working towards your goal, take time to reflect on your progress and identify areas where you can improve. This could be anything from streamlining your morning routine to finding a more effective way to study for exams. By constantly evaluating and improving your process, you’ll not only achieve your goals more efficiently, but you’ll also set yourself up for success in the future.

Kaizen is often used in conjunction with other quality improvement tools, such as Six Sigma and Lean Manufacturing. When used together, these tools can help businesses achieve amazing results.

What are the Kaizen Principles?

The Kaizen principles are:

1. Start by questioning the best practices
2. Follow the principle of Continuous improvement

10. Kaizen is often used in conjunction with other quality improvement tools, such as Six Sigma and Lean Manufacturing.
11. Embrace Change or Keep your mind open to change
12. Kaizen principles can be applied to any area of life

Who should use Kaizen?

Kaizen is a philosophy of continuous improvement that can be used by anyone in any field.

The kaizen philosophy can be traced back to Deming’s 14 Points, which were a set of principles for quality management developed by W. Edwards Deming. One of Deming’s points was “Continuous improvement.” The kaizen philosophy took this idea and ran with it, further developing the concepts of continuous improvement and applying them to all aspects of life.

Kaizen is often used in business settings, but it can be applied to any area of your life. For example, you could use kaizen to improve your health, relationships, finances, or personal productivity.

2. Gemba: As I said kaizen is not something conducted in a closed room. We get out of the office and see it for ourselves.
3. Get your hands dirty: We learn by doing. We roll up our sleeves and try stuff. We run experiments to prove cause and effect. Then we lock in countermeasures with standardized work and visual management. Lastly, we share what we have learned.

Real-Life Examples of Kaizen

#1 Case Study

Problem Statement: Material Over-stacking

Description: At one of our client’s materials was stacked up to 7 feet. It leads to material falling and several accidents. To solve this problem we came up with Ideas to do maximum stacking height marking throughout the WIP area of the plant.

This improvement restricted stacking to a maximum of 4 feet. Avoiding all safety hazards.

This kaizen helped improve safety and it is an example of point Kaizen.

#2 Case Study

Problem Statement: High Tool  Set-up Time.

Description: One of our clients was facing a high set-up time issue. We made a spaghetti Diagram for the process and we observed the operator was moving to and fro to get various tools for set-up as per need. The number of trips was as much as 9 trips per set-up.

To avoid these many trips we designed the following trolley. Which has all the tools in one place? Tools are properly identified on the trolley. The operator can move the trolley to the station where set-up has to be done. It reduced the number of trips from 9 trips to 1 trip per set-up.

It led to a reduction of 25% set-up time.

This kaizen is an example of a flow kaizen.

#3 Case Study

Problem Statement: FIFO is not followed in the RM area.

Description: One of our clients was facing an issue with maintaining FIFO in the RM area. Leading to Inventory waste. We implemented a FIFO BOARD as shown below.

For implementing the FIFO board we identified the RM location for each RM Rack and designated it a unique number.

Channels on the FIFO board contain location cards for every material grade. Cards are to be entered from one direction and moved forward. Material as per location on the First card towards the outer section of the channel is the oldest material and hence should be used first.

This is an example of the system Kaizen.
