Understanding Kanban

A. Origins of Kanban in manufacturing

Kanban, a Japanese term meaning “visual signal” or “card,” has its roots deeply embedded in the Toyota Production System (TPS) of the late 1940s. The system was developed by Taiichi Ohno, an industrial engineer at Toyota, as a method to improve manufacturing efficiency and reduce waste.

The Toyota Production System

The TPS was designed to address several key challenges faced by Toyota in the post-World War II era:

1. Limited resources
2. High competition in the automotive industry
3. Need for improved efficiency and quality

Ohno’s goal was to create a system that could produce high-quality vehicles quickly and efficiently, while minimizing waste and inventory costs. This led to the development of the “Just-In-Time” (JIT) production philosophy, which is the foundation of Kanban.

Just-In-Time Production

JIT production is based on the principle of producing only what is needed, when it is needed, and in the amount needed. This approach helps to:

• Reduce inventory costs
• Minimize waste
• Improve production flexibility
• Enhance quality control

Kanban was developed as a tool to implement and manage JIT production effectively.

The Kanban System in Manufacturing

In its original form, Kanban used physical cards to signal the need for more parts or materials in the production process. Here’s how it worked:

1. Each part or material had a corresponding Kanban card.
2. When a worker used a part, they would remove the Kanban card and send it back to the previous stage in the production process.
3. This card acted as a signal for the previous stage to produce more of that part.
4. The process continued, creating a pull system where production was driven by actual demand rather than forecasts.

This system helped Toyota achieve several benefits:

• Reduced overproduction
• Minimized inventory levels
• Improved production flow
• Enhanced visibility of the production process

Influence on Lean Manufacturing

The success of the Kanban system at Toyota played a crucial role in the development of Lean Manufacturing principles. Lean Manufacturing focuses on:

1. Eliminating waste
2. Continuous improvement
3. Respect for people
4. Creating value for customers

Kanban’s ability to visualize work, limit work in progress, and promote a pull system aligns perfectly with these Lean principles.

Global Adoption of Kanban in Manufacturing

The success of Kanban at Toyota led to its widespread adoption in manufacturing industries worldwide. Companies across various sectors, including:

• Automotive
• Electronics
• Aerospace
• Consumer goods

B. Core principles of Kanban

As Kanban evolved from its manufacturing origins, it developed a set of core principles that guide its implementation across various industries and disciplines. These principles form the foundation of the Kanban method and are essential for understanding its application in project management.

1. Visualize the Workflow

The first and perhaps most fundamental principle of Kanban is the visualization of work. This principle stems directly from the system’s origins in manufacturing, where physical cards were used to represent work items.

Key aspects of workflow visualization:

• Kanban board: A visual representation of the workflow, typically divided into columns representing different stages of work.
• Kanban cards: Representing individual work items or tasks.
• Work-in-Progress (WIP) limits: Visual indicators of capacity limits for each stage of work.

Benefits of visualization:

1. Increased transparency
2. Better understanding of the current state of work
3. Easier identification of bottlenecks and inefficiencies
4. Improved communication among team members

Example of a basic Kanban board:

2. Limit Work in Progress (WIP)

Limiting WIP is a crucial principle that helps teams focus on completing tasks before starting new ones. This principle is derived from the Just-In-Time production philosophy of Toyota.

Key aspects of limiting WIP:

• Setting WIP limits for each stage of the workflow
• Preventing overload and multitasking
• Encouraging team members to collaborate and finish current tasks

Benefits of limiting WIP:

1. Reduced lead times
2. Improved quality of work
3. Increased productivity
4. Better predictability of workflow

Strategies for implementing WIP limits:

• Start with observing current work patterns
• Set initial limits based on team capacity and workflow
• Adjust limits as needed through experimentation and feedback

3. Manage Flow

Managing flow in Kanban refers to the continuous movement of work items through the system. The goal is to create a smooth, predictable flow of work from start to finish.

Key aspects of managing flow:

• Identifying and addressing bottlenecks
• Balancing demand with capacity
• Minimizing blockers and dependencies

Techniques for managing flow:

1. Class of Service: Prioritizing work based on urgency and impact
