What is kanban

Introduction

Kanban is a visual system for managing and optimising work processes. It originated as a scheduling system for Toyota’s manufacturing line in the 1940s and has since been adapted and applied to many other industries and types of work. Kanban is based on the idea of using visual signals to control and improve the flow of work and is grounded in several key principles. In this article, we’ll explore what Kanban is, how it works, and how it can be applied in different contexts.

Japanese meaning

Kanban is a Japanese term that means “signboard” or “billboard”. In the context of work management, it refers to a visual system that uses cards or other signals to represent work items and track their progress through a process.

Kanban is based on the principle of “pulling” work through the system, rather than “pushing” it from one stage to the next. This means that work is only started when there is capacity to handle it, rather than simply adding more work to an already overloaded system.

History of Kanban

Kanban was first developed by Taiichi Ohno, a Toyota engineer, in the late 1940s. Ohno wanted to find a way to optimise the flow of materials through the manufacturing process and reduce waste. He introduced the use of a simple card system to signal the need for materials and help regulate production.

Over time, the Kanban system was refined and adapted to other areas of the production line, and eventually spread to other industries and types of work.

Key principles of Kanban

Kanban is based on several key principles, including visualising work, limiting work in progress (WIP), managing flow, making process policies explicit, implementing feedback loops, and continuously improving.

These principles are designed to help teams and organisations optimise their work processes, reduce waste, and increase efficiency and quality.

Throughout this article, we’ll explore how these principles are applied in practice using Kanban boards, WIP limits, metrics, and other tools and techniques.

Setting up a Kanban system

To implement a Kanban system, you’ll need to understand your workflow, design a Kanban board, choose work items, establish WIP limits, and determine how work is pulled through the system. In this section, we’ll explore each of these steps in more detail.

Understanding your workflow

The first step in setting up a Kanban system is to understand your workflow. This involves mapping out the stages of your process, identifying any bottlenecks or inefficiencies, and determining the key metrics you’ll use to measure progress and performance.

By understanding your workflow, you’ll be able to design a Kanban system that is tailored to your specific needs and goals.

Designing a Kanban board

The Kanban board is the visual representation of your workflow and is typically divided into columns that represent the stages of the process (such as “To Do”, “In Progress”, and “Done”). The Kanban board can be physical or digital and can be customised to fit the specific needs of your team or organisation.

It should be easy to understand and use and should provide clear visibility into the status of work items at any given time.

Choosing work items and categorising them

To use a Kanban system effectively, you’ll need to choose work items and categorise them according to their type, priority, and other relevant factors. This can be done using cards or other signals that are placed on the Kanban board.

By categorising work items in this way, you’ll be able to prioritise them, manage them more effectively, and ensure that the right work is being done at the right time.

Establishing WIP limits

WIP (work in progress) limits are a key component of Kanban, as they help to prevent overloading the system and ensure that work is completed in a timely and efficient manner. WIP limits are typically set for each stage of the process and help to ensure that there are not too many work items in progress at any given time.

By limiting WIP, you’ll be able to reduce multitasking, improve flow, and identify bottlenecks more easily.

Determining how work is pulled through the system

The final step in setting up a Kanban system is to determine how work is pulled through the system. This involves establishing rules and policies for how work items are moved from one stage to the next and ensuring that these rules are understood and followed by all team members.

By implementing clear rules and policies, you’ll be able to manage the flow of work more effectively and ensure that work is completed in a consistent and efficient manner.

Managing work with Kanban

Once you’ve set up a Kanban system, the next step is to use it to manage your work effectively. In this section, we’ll explore some best practices for managing work with Kanban, including monitoring progress, managing bottlenecks, and improving your process.

Monitoring progress with metrics

One of the key benefits of Kanban is that it provides visibility into the status of work items at any given time. To make the most of this visibility, you’ll need to establish metrics that help you track progress and identify areas for improvement.

These metrics might include lead time (the time it takes for a work item to move from start to finish), cycle time (the time it takes to complete one iteration of a process), and throughput (the rate at which work items are completed).

Managing bottlenecks and flow

Bottlenecks are a common problem in any work process and can cause delays and reduce efficiency. There are several Kanban tools and techniques for managing bottlenecks and improving flow, including limiting WIP, identifying and resolving blockers, and using expedite lanes to prioritise urgent work.

By managing bottlenecks effectively, you’ll be able to ensure that work is completed in a timely and efficient manner.

Improving your process with continuous improvement

Continuous improvement is a core principle of Kanban and involves regularly reviewing and analysing your work process to identify areas for improvement. This might involve conducting retrospectives, analysing metrics, and soliciting feedback from team members and stakeholders.

By continuously improving your process, you’ll be able to reduce waste, increase efficiency, and deliver higher-quality work.
