What is Kaizen?

Kaizen is a Japanese concept for continuous improvement. The concept of Kaizen is often linked with doing little by little improvements rather than waiting for an important change that will solve the problem.

The logic behind this approach is quite simple: instead of accepting the fact that something has been done in a specific way forever, teams constantly try to improve the process by removing unnecessary actions, improving the quality of the work, saving time, or simplifying the work.

In addition, Kaizen involves participation of employees in improvements because those who use the process daily know much more about its flaws than management.

For example, a call center providing customer service may discover that the major part of employee time is spent on information search before answering customers. In this case, Kaizen helps to analyze the process, find out the reason of delay and make improvements to have access to necessary information quickly.

What are the key principles of Kaizen?

Some of the key principles of Kaizen are:

• Continuous improvement: Work on making improvements through minor changes.
• Employee involvement: Involve the workers in finding ways to make things better.
• Waste elimination: Identify actions that waste time or money without providing value.
• Root cause analysis: Find the underlying cause of a problem.
• Standardization: Integrate improvements into the process.
• Respect for people: Create an environment in which employees can share their views and raise problems.

How does Kaizen work?

The most common practice for Kaizen follows the PDCA cycle: Plan, Do, Check, Act.

• Plan: Detect a problem and determine a small improvement that can resolve the issue.
• Do: Implement a trial of the improvement on a small scale.
• Check: Analyze the effects and measure whether improvements have been made.
• Act: If the improvement proved successful, it becomes standard. Otherwise, you should revise the process and try again.

Kaizen improvement cycle includes the following steps:

Detect a problem → Discover the root cause → Propose an improvement → Try the change → Measure the effect → Standardize the improvement → Repeat

What is Kanban?

Kanban is a visual system for managing workflow. This allows teams to identify which tasks are in progress, completed tasks, and any bottlenecks within the workflow. A typical Kanban board will have columns such as To Do, In Progress, Review, and Done. Work items will be displayed using cards which flow through the columns according to the work progress.

This simple tool can easily show any problems in the work process, for instance, there is a lot of work in the Review column but very little in the Done column, it means that the team faces a bottleneck in the reviewing process.

Kanban is based on the pull system, which implies that new work is started only when there is capacity available to start it.

What are the core principles of Kanban?

Kanban core principles are:

• Work should be visualized: The tasks and their statuses should be visible.
• Work-in-progress limit should be imposed: Too many tasks shouldn’t be processed simultaneously.
• Work flow should be managed: It should be observed if there are any work flow delays, queues, or bottlenecks.
• Policies should be made explicit: The procedure of task movement from one state to another should be clearly defined.
• Feedback loops should be implemented: The work flow performance should be constantly reviewed.
• Improvements should be made collaboratively: It should be based on the observations of the workflow performance.
• Start with the existing process: Improve the current workflow instead of requiring a complete redesign from the beginning.

How does Kanban work?

The basic flow of the Kanban system looks like:

Visualization of Work → Definition of Workflow → Establishment of WIP Limits → Management of Flow → Identification of Bottlenecks → Improvement → Measurement → Repeat

For instance, in case a software development team has ten jobs tagged as “In Progress” while there are only two developers who can do these tasks. This will make work disorganized and will make the process slower. With a WIP limit, the team will be encouraged to finish the work they started.

These teams measure the efficiency of flow in terms of parameters like cycle time (time taken to complete an item), lead time (time between demand and delivery of an item), and throughput (number of items done within a given timeframe). Through these metrics, it becomes possible to determine the flow improvement level.

Kaizen vs Kanban: How do they approach improvement differently?

Kaizen focuses on identifying areas of improvement within the process, whereas Kanban focuses on finding bottlenecks within the process.

Kaizen improves the process

Kaizen starts with the question: “How can we make this process better?” 

Kaizen examines the way in which work is carried out and focuses on improving the process itself. It eliminates waste, resolves the issues that occur regularly, and develops good habits. The improvement is triggered by suggestions offered by the team members and tested via experiments. Kaizen is effective in cases when certain problems appear repeatedly in the process, for example, mistakes, approvals, or handovers.

Kanban improves the flow of work

Kanban asks: “How can we make work flow better?”

Unlike Kaizen, Kanban does not aim to improve the process immediately. Instead, it starts with making the process visible. Once the process is visualized in the board, the areas of delays and excess load are clearly seen. Then WIP limits, policies, and priorities are changed to make sure the process flows. Kanban is most useful in situations when there are too many tasks at once or bottlenecks.

Can Kaizen and Kanban be used together?

Yes, they can work well together as they serve different yet related improvement needs. Whereas Kanban helps in knowing the problem areas, Kaizen would be able to provide a solution for the problem area. Kanban board can again be used to know whether the change has made any difference to the process.

Example of using Kaizen with Kanban

Consider a software development team working with a Kanban board.

The team sees that a few days are spent on testing tasks before they reach their completion point. This delay is shown clearly through the Kanban board.

Next, Kaizen methodology is used to find out the root cause of the problem. It is found out that testing processes are inconsistent and there is a lot of manual effort involved.

Kaizen vs Kanban for Agile and Lean teams

Both approaches can be useful for modern teams, but they play different roles.

Kaizen in Lean management

Kaizen is among the basic concepts that form the basis of the Lean methodology. In Lean management, value is created by eliminating waste and Kaizen is the method of doing this. 

As the Lean framework was developed under the inspiration of the Toyota Production System, Kaizen becomes essential to its functioning since the process requires continuous improvement performed by the employees who are directly involved in their work. Organizations practicing Lean management encourage their staff members to provide their suggestions for improvement on a regular basis.

Kanban in Agile teams

Agility and rapid feedback are two of the main attributes of an agile team and Kanban fits well into these two aspects. There are agile teams which use Kanban by itself, whereas others may use Kanban with Scrum to create a new hybrid model called Scrumban. The visibility through the Kanban board and WIP constraints help the team maintain focus. Agile retrospectives could also be considered as Kaizen activities.

Kaizen vs Kanban: Which one should you choose?

The Kaizen vs Kanban decision depends on the problem a team is trying to solve.

• Choose Kaizen when the same process problems keep coming back, when waste or rework is high, or when the team wants to build a culture of small, regular improvement.
• Choose Kanban when work feels messy or overloaded, when nobody is sure what is in progress, or when bottlenecks keep delaying delivery.
• Choose both when a team wants to see its work clearly and also keep improving how that work gets done.

Conclusion

Kaizen and Kanban address different but connected improvement needs within a team or organization. Kaizen focuses on continuous process improvement, waste reduction, and solving recurring problems, while Kanban focuses on workflow visibility, WIP management, and smoother flow.

They are not competing approaches and can work effectively together. Choosing between them depends on whether the main challenge is improving the process, improving workflow, or addressing both.
