Introduction
Kanban is a visual technique for managing and enhancing work processes. It began as a scheduling system for Toyota’s production line in the 1940s and has since been modified and applied to a wide range of industries and work types. Kanban focuses on the use of visual indicators to control and improve work flow and is built on several core principles. In this article, we will discuss what Kanban is, how it operates, and how it can be applied in various settings.
Japanese meaning
Kanban is a Japanese word that translates to “signboard” or “billboard.” In the realm of work management, it refers to a visual system that uses cards or other markers to represent work items and track their progress through a process.
Kanban follows the principle of “pulling” work through the system instead of “pushing” it from one phase to the next. This approach ensures that work is only initiated when there is available capacity, rather than simply adding more tasks to an already overwhelmed system.
Kanban History
Kanban was originally developed by Taiichi Ohno, a Toyota engineer, in the late 1940s. Ohno aimed to create a method for optimizing the flow of materials in the manufacturing process and reducing waste. He implemented a basic card system to indicate the need for materials and control production.
Over time, the Kanban system was further developed and expanded to other parts of the production line, eventually finding its way into other industries and types of work.
Principles of Kanban
Kanban is based on several essential principles, such as visualizing work, limiting work in progress (WIP), managing flow, making process policies explicit, integrating feedback loops, and pursuing continuous improvement.
These principles are intended to help teams and organizations optimize their work processes, eliminate waste, and enhance efficiency and quality.
In this article, we will explore how these principles are put into action using Kanban boards, WIP limits, metrics, and other tools and strategies.
How to set up a Kanban system
To build a Kanban system, you must comprehend your workflow, create a Kanban board, pick work items, apply WIP limits, and outline how work is pulled through the system. In this section, we will examine each of these elements in more depth.
Understanding the workflow
The first step in building a Kanban system is to grasp your workflow. This involves mapping out the stages of your process, detecting bottlenecks or inefficiencies, and identifying the key metrics for assessing progress and performance.
By knowing your workflow, you can design a Kanban system that aligns with your unique needs and goals.
Designing a Kanban board
The Kanban board is the visual display of your workflow and is generally divided 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 customized to fit the specific needs of your team or organization.
It should be easy to understand and use, providing 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 need to choose work items and categorize them based on their type, priority, and other relevant factors. This can be done using cards or other visual indicators on the Kanban board.
By categorizing work items in this way, you can prioritize tasks, manage them more effectively, and ensure that the right work is being completed at the right time.
Establishing the WIP limits
WIP (work in progress) limits are a crucial 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, making sure that there aren’t too many work items in progress at any given time.
By setting WIP limits, you can reduce multitasking, improve flow, and more easily identify bottlenecks.
Determining how work is pulled through the system
The last step in setting up a Kanban system is to determine how work is pulled through the system. This involves creating rules and policies for moving work items from one stage to the next and ensuring that all team members understand and adhere to these rules.
By establishing clear rules and policies, you can effectively manage the flow of work and ensure that tasks are completed consistently and efficiently.
Managing work with Kanban
Once you’ve implemented a Kanban system, the subsequent step is to utilize it to effectively manage your work. This section will examine some best practices for managing work with Kanban, including tracking progress, handling bottlenecks, and refining your process.
Monitoring progress with metrics
A primary benefit of Kanban is that it offers visibility into the status of work items at any point in time. To maximize this visibility, you must establish metrics that assist in tracking progress and identifying areas for improvement.
These metrics could consist of lead time (the duration required for a work item to move from start to completion), cycle time (the time necessary to finish 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 result in delays and reduced efficiency. There are several Kanban tools and techniques designed to manage bottlenecks and improve flow, including limiting WIP, identifying and addressing blockers, and employing expedite lanes to prioritize urgent tasks.
By effectively managing bottlenecks, you can ensure work is completed both promptly and efficiently.
Improving your processes
Continuous improvement is a central tenet of Kanban and entails regular review and analysis of your work process to pinpoint areas for improvement. This might involve holding retrospectives, studying metrics, and gathering feedback from team members and stakeholders.
By continuously enhancing your process, you can decrease waste, augment efficiency, and deliver higher-quality work.
Adapting Kanban to fit different contexts
Although Kanban has been successfully employed across different contexts, it may require adaptation to cater to the specific needs and requirements of each context.
Applying Kanban in diverse fields
Kanban can be employed in various fields, including software development, healthcare, and marketing. While the fundamental principles of Kanban stay constant, the specific techniques and tools used may differ based on the context.
Integrating Kanban with other frameworks
Kanban can operate independently or be combined with other frameworks, such as Agile or Lean. When integrated with other methodologies, Kanban can offer additional advantages and tackle distinct challenges.
Kanban across different contexts
Kanban is a flexible methodology that can be applied across multiple contexts, including software development, healthcare, and marketing.
Applying Kanban in software development
Kanban is often used in software development to manage the complete development process, from requirements gathering to testing and deployment.
