Kanban is a popular Lean workflow management method that helps teams visualize work, maximize efficiency, and improve continuously. It is an Agile methodology that focuses on delivering value to the customer and minimizing waste. Kanban is all about creating a smooth flow of work and reducing bottlenecks in the process.

Kanban boards are used to manage work items and track progress. They provide a visual representation of the workflow, with tasks represented as cards that move through stages of work represented as columns. This makes it easy for team members to see what needs to be done, what is in progress, and what has been completed. Kanban boards can be customized to fit the needs of any team or project.

Lean project management is a philosophy that emphasizes continuous improvement and customer value. It is based on the principles of Lean manufacturing, which were developed by Toyota in the 1950s. Lean project management aims to eliminate waste and increase efficiency in every phase of a project. By applying Lean principles to project management, teams can deliver high-quality work on time and within budget.

What is Kanban?

Kanban is a popular Lean workflow management method for defining, managing, and improving services that deliver knowledge work. It helps visualize work, maximize efficiency, and improve continuously. Kanban is an Agile management method built on a philosophy of continuous improvement, where work items are "pulled" from a product backlog into a steady flow of work. The framework is applied using Kanban boards—a form of visual project management. In a Kanban board, tasks—represented as cards—move through stages of work—represented as columns.

The Origins of Kanban

Kanban originated in the manufacturing industry, specifically at Toyota, where it was used to improve production processes. The word "kanban" is Japanese for "visual signal" or "card." The method was developed to help manage inventory and production levels in a just-in-time (JIT) manufacturing system. The goal was to eliminate waste and improve efficiency by only producing what was needed, when it was needed.

The Principles of Kanban

Kanban is based on several key principles:

  • Visualize the workflow: Use a Kanban board to create a visual representation of the workflow. This helps identify bottlenecks and areas for improvement.
  • Limit work in progress (WIP): Set WIP limits to prevent overloading the system and improve flow.
  • Manage flow: Continuously monitor and improve the flow of work through the system.
  • Make process policies explicit: Clearly define the process and policies for each stage of the workflow.
  • Implement feedback loops: Use feedback loops to continuously improve the process and the product.

These principles help teams focus on delivering value to the customer, while improving the efficiency of the process. By visualizing the workflow, limiting WIP, and managing flow, teams can reduce waste and improve the quality of the product.

How does Kanban work?

Kanban is a lean project management framework that emphasizes continuous improvement and the delivery of customer value. It is based on the principles of visualizing work, limiting work in progress, managing flow, making process policies explicit, and implementing feedback loops.

Visualizing the Workflow

One of the key principles of Kanban is visualizing the workflow. This involves creating a visual representation of the work that needs to be done and the stages it goes through. This can be done using a Kanban board, which is a simple tool that consists of columns and cards. Each card represents a work item, and each column represents a stage in the workflow. Team members can move the cards from one column to the next as the work progresses, giving everyone visibility into the status of the work. Check out our list of the 10 best Kanban software of 2023:

Limiting Work in Progress

Another important principle of Kanban is limiting work in progress. This means that the team should only work on a limited number of items at a time to avoid overloading the system. By limiting work in progress, the team can focus on completing tasks before starting new ones, which helps to reduce lead times and improve flow.

Managing Flow

Kanban also emphasizes managing flow. This means that the team should strive to achieve a smooth and steady flow of work through the system. To achieve this, the team needs to identify bottlenecks and other obstacles that are slowing down the flow of work and take steps to eliminate them. This can involve reorganizing the workflow, improving communication, or making other changes to the process.

Making Process Policies Explicit

Another principle of Kanban is making process policies explicit. This means that the team should have clear policies and rules for how work is done. By making these policies explicit, the team can ensure that everyone understands how the process works and can work together more effectively. This can involve creating standard operating procedures, documenting best practices, or other forms of process documentation.

Implementing Feedback Loops

Finally, Kanban emphasizes implementing feedback loops. This means that the team should regularly review the process and look for areas where it can be improved. This can involve gathering feedback from customers, team members, or other stakeholders, and using that feedback to make changes to the process. By implementing feedback loops, the team can continuously improve the process and deliver more value to the customer.

Benefits of Kanban

Increased Efficiency

Kanban is a Lean project management methodology that helps teams increase their efficiency by visualizing their workflow and limiting work in progress (WIP). By focusing on completing one task at a time, teams can reduce the time it takes to complete a project and improve their overall productivity.

With Kanban, teams can also identify bottlenecks in their workflow and take steps to resolve them. This helps to ensure that work is flowing smoothly and that projects are completed on time.

Improved Quality

Kanban also helps teams improve the quality of their work by promoting continuous improvement. By measuring flow, quality, and lead time, teams can identify areas where they can make improvements and implement changes to prevent problems in the future.

By focusing on delivering high-quality work, teams can improve customer satisfaction and build a reputation for excellence.

Enhanced Collaboration

Kanban promotes collaboration between team members by encouraging them to work together to complete tasks. By visualizing their work on a Kanban board, team members can see what tasks are in progress, what tasks are completed, and what tasks are still to be done.

This helps team members to communicate more effectively and to work together to complete tasks more efficiently. By working together, teams can achieve their goals more quickly and effectively.

Greater Flexibility

Kanban is a flexible methodology that can be adapted to suit the needs of any team. Kanban boards can be customized to reflect the unique workflow of each team, and teams can adjust their WIP limits to ensure that they are working at a sustainable pace.

With Kanban, teams can also respond quickly to changes in their environment. By visualizing their work and limiting their WIP, teams can quickly identify when they need to shift their focus to a new task or project.

Limitations of Kanban

Kanban is a popular project management methodology that helps teams visualize their work, limit work-in-progress, and improve efficiency. While it has many benefits, it also has some limitations that teams should be aware of before implementing it.

Not Suitable for Complex Projects

Kanban is best suited for projects with a high degree of variability and unpredictability. It is not well-suited for complex projects that require a lot of planning and coordination. Kanban works best when the work can be broken down into small, discrete tasks that can be completed quickly and independently. For complex projects, a more robust project management methodology may be required.

Requires a Culture of Continuous Improvement

Kanban is a methodology that is built on the principles of continuous improvement. It requires a culture of experimentation, learning, and adaptation. Teams that are not willing to embrace these principles may struggle to implement Kanban effectively. In addition, Kanban requires a high degree of transparency and collaboration, which may be difficult for teams that are not used to working in this way.

Limited to Small Teams

Kanban is most effective when used by small teams that are working on a limited number of projects. As the number of projects and team members increases, it can become more difficult to manage the flow of work and maintain the visualizations that are so important to the methodology. For larger teams or organizations, a more robust project management methodology may be required.
