I. Introduction To Kanban

Kanban Methodology: Achieving Agile Project Success · ActiveCollab

Kanban is a lean methodology that originated in Japan and is widely used in project management. The word Kanban means ‘visual signal’ or ‘card’ in Japanese. The methodology is based on the principles of just-in-time production, where the production of goods is triggered only when the demand arises.

Kanban was first used in Toyota’s manufacturing process, but it has since been adopted by many other industries, including software development, healthcare, and education. The methodology is designed to help teams improve their workflow, minimize waste, and increase efficiency.

The Kanban board is the central component of the methodology. It is a visual representation of the team’s workflow, and it helps team members to understand the status of each task. The board is divided into columns, and each column represents a different stage of the workflow.

A Kanban board typically has three columns: ‘To Do’, ‘In Progress’, and ‘Done’. Each task is represented by a card that moves from one column to another as it progresses through the workflow. The team can easily see the status of each task and identify any bottlenecks in the workflow.

The Kanban methodology emphasizes continuous improvement, and teams are encouraged to make small, incremental changes to their workflow to optimize their processes. The methodology is flexible and can be adapted to suit the needs of different teams and industries.

A. Origin of Kanban

The Kanban methodology originated in the 1940s in Toyota’s manufacturing process in Japan. The company was looking for a way to improve their production process and minimize waste. Toyota’s engineers observed the way supermarkets restocked their shelves, and they realized that they could apply the same principles to their manufacturing process.

They developed a system where workers would produce only what was needed, and they would only produce it when it was needed. Workers would pull parts from the previous step in the production process only when they needed them, and this would trigger the production of more parts. This system allowed Toyota to minimize waste and improve their efficiency.

B. Kanban and Toyota Production System

The Kanban methodology is an integral part of the Toyota Production System, which is also known as lean manufacturing. The system is based on a set of principles that aim to improve efficiency, minimize waste, and continually improve processes.

The Toyota Production System focuses on two main pillars: just-in-time production and jidoka, which is the principle of stopping the production process when a problem occurs. The Kanban methodology is a key component of the just-in-time production pillar, as it helps to ensure that production only occurs when there is demand for the product.

The Toyota Production System has been widely adopted by many industries around the world, and the Kanban methodology has become an essential part of project management in many organizations.

III. Key Principles of Kanban

What Is the Kanban System?

A. Pull-based System
