Introduction
Kanban is a visual method for managing and enhancing work processes. Initially designed as a scheduling system for Toyota’s assembly line in the 1940s, it has since been adapted for use in numerous other industries and work types. Kanban focuses on using visual indicators to manage and improve work flow, following several primary principles. In this article, we will discuss what Kanban is, how it operates, and how it can be employed in a variety of contexts.
Meaning of Kanban in Japanese
Kanban is a Japanese word that means “signboard” or “billboard.” In the context of work management, it refers to a visual system that utilizes cards or other signs 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 approach ensures that work is only initiated when there is enough capacity to handle it, rather than simply adding more tasks to an already congested system.
History
Kanban was first created by Taiichi Ohno, a Toyota engineer, in the late 1940s. Ohno aimed to develop a method for optimizing the flow of materials in the manufacturing process and minimizing waste. He implemented a simple card system to signal the requirement for materials and control production.
Over time, the Kanban system was refined and extended to other parts of the production line, eventually making its way into other industries and types of work.
Kanban principles
Kanban is centered around several fundamental principles, such as visualizing work, limiting work in progress (WIP), managing flow, making process policies explicit, establishing feedback loops, and continually improving.
These principles are designed to help teams and organizations streamline their work processes, eliminate waste, and promote efficiency and quality.
In this article, we will investigate how these principles are put into practice using Kanban boards, WIP limits, metrics, and other tools and techniques.
Setting up a Kanban system
To create a Kanban system, you must familiarize yourself with your workflow, design a Kanban board, pick work items, define WIP limits, and decide how work is pulled through the system. In this section, we will delve into each of these aspects in greater depth.
Understanding your workflow
The first stage in developing a Kanban system is grasping your workflow. This entails outlining the steps of your process, pinpointing bottlenecks or inefficiencies, and identifying the main metrics to evaluate progress and performance.
By knowing your workflow, you can design a Kanban system that aligns with your unique needs and objectives.
Designing a Kanban board
The Kanban board is the visual display of your workflow, typically organized into columns that represent the stages of the process (such as “To Do”, “In Progress”, and “Done”). The Kanban board can be either physical or digital and can be adapted to the specific requirements of your team or organization.
It should be user-friendly and easy to comprehend, offering clear visibility of work item statuses at all times.
Choosing work items and categorising them
Effectively utilizing a Kanban system requires choosing work items and categorizing them based on factors such as type, priority, and other relevant aspects. This can be achieved using cards or other signals on the Kanban board.
Categorizing work items in this manner enables you to prioritize tasks, manage them more effectively, and ensure the right work is done at the appropriate time.
Establishing WIP limits
WIP (work in progress) limits are a crucial component of Kanban, as they prevent system overload and guarantee that work is finished in a timely and efficient manner. WIP limits are usually set for each stage of the process, ensuring that an excessive number of work items are not in progress concurrently.
Limiting WIP allows you to decrease multitasking, improve flow, and more easily identify bottlenecks.
Determining how work is pulled through the system
The final phase in setting up a Kanban system is deciding how work is pulled through the system. This involves creating rules and policies for moving work items from one stage to another, as well as ensuring that all team members understand and follow these rules.
By employing clear rules and policies, you can better manage work flow and ensure that tasks are completed in a consistent and efficient manner.
Managing work with Kanban
After implementing a Kanban system, the following step is to leverage it to manage your work effectively. This section will cover some best practices for managing work with Kanban, such as monitoring progress, handling bottlenecks, and optimizing your process.
Monitoring progress with metrics
One primary benefit of Kanban is the visibility it provides into the status of work items at any particular time. To maximize this visibility, it’s essential to develop metrics that help in tracking progress and pinpointing areas for improvement.
These metrics may include lead time (the duration a work item takes to progress from start to finish), cycle time (the time required to complete one iteration of a process), and throughput (the rate at which work items are completed).
Managing bottlenecks and flow
Bottlenecks frequently occur in any work process and can lead to delays and reduced efficiency. A variety of Kanban tools and techniques are available for managing bottlenecks and improving flow, such as limiting WIP, identifying and addressing blockers, and employing expedite lanes to prioritize urgent work.
By effectively managing bottlenecks, 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 concept of Kanban and involves consistently reviewing and analyzing your work process to identify areas for improvement. This may include holding retrospectives, analyzing metrics, and soliciting feedback from team members and stakeholders.
By continually refining your process, you’ll be able to reduce waste, enhance efficiency, and deliver high-quality work.
