Introduction
Kanban is a visual strategy for managing and streamlining work processes. Initially developed as a scheduling system for Toyota’s assembly line in the 1940s, it has been modified and applied in numerous other industries and work types. Kanban emphasizes the use of visual signals to manage and enhance work flow and adheres to several primary principles. In this article, we will explore what Kanban is, how it functions, and how it can be employed across different contexts.
Meaning of Kanban
Kanban is a Japanese term that translates to “signboard” or “billboard.” In the realm of work management, it refers to a visual system that uses cards or other signs to represent work items and track their progress through a process.
Kanban follows the principle of “pulling” work through the system, rather than “pushing” it from one stage to another. This means that work is only started when there is adequate capacity to manage it, rather than simply adding more tasks to an already full system.
Kanban history
Kanban was first developed by Taiichi Ohno, an engineer at Toyota, in the late 1940s. Ohno aimed to create a method for optimizing the flow of materials within the manufacturing process and reducing waste. He introduced a basic card system to signal the need for materials and regulate production.
Over time, the Kanban system was improved and extended to other aspects of the production line and eventually spread to other industries and types of work.
Key principles of Kanban
Kanban revolves around several fundamental principles, such as visualizing work, limiting work in progress (WIP), managing flow, making process policies explicit, implementing feedback loops, and constantly improving.
These principles are intended to help teams and organizations optimize their work processes, minimize waste, and boost efficiency and quality.
Throughout this article, we will examine how these principles are applied in practice using Kanban boards, WIP limits, metrics, and other tools and approaches.
How to set up a Kanban system
To create a Kanban system, you need to familiarize yourself with your workflow, craft a Kanban board, identify work items, set WIP limits, and figure out how work is pulled through the system. In this section, we will delve into each of these aspects in greater detail.
Understanding your workflow
The first step in establishing a Kanban system is to comprehend your workflow. This involves charting the steps of your process, pinpointing any bottlenecks or inefficiencies, and determining the primary metrics for evaluating progress and performance.
By grasping your workflow, you can design a Kanban system that caters to your specific requirements and targets.
Designing Kanban boards
The Kanban board is the visual depiction of your workflow and is generally split into columns that symbolize 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 particular needs of your team or organization.
It should be easy to interpret and operate, offering clear visibility into the status of work items at any given moment.
Choosing work items and categorising them
To use a Kanban system efficiently, you need to select work items and categorize them based on their type, priority, and other pertinent factors. This can be accomplished using cards or other visual signals placed on the Kanban board.
Categorizing work items in this manner enables prioritization, more effective management, and ensures that the right tasks are being tackled at the appropriate time.
Establishing WIP limits
WIP (work in progress) limits are an essential aspect of Kanban, as they help avert overloading the system and ensure that work is completed efficiently and promptly. WIP limits are usually set for each phase of the process, ensuring that there aren’t too many work items in progress simultaneously.
By instituting WIP limits, you can curtail multitasking, optimize flow, and more readily spot bottlenecks.
Determining the work to be 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 devising rules and policies for transferring work items from one stage to the next and ensuring that all team members understand and comply with these rules.
By implementing clear rules and policies, you can effectively manage the flow of work and ensure tasks are completed consistently and efficiently.
Using Kanban to manage work
After setting up a Kanban system, the following step involves using it to efficiently manage your work. This section will discuss some best practices for managing work with Kanban, such as overseeing progress, handling bottlenecks, and refining your process.
Monitoring progress with metrics
A primary advantage of Kanban is its ability to provide transparency into the status of work items at any given moment. To maximize this visibility, it’s important to develop metrics that facilitate tracking progress and pinpointing areas for improvement.
These metrics may include lead time (the duration a work item takes to progress from beginning to end), cycle time (the time necessary to complete one iteration of a process), and throughput (the pace at which work items are completed).
Managing bottlenecks and flow
Bottlenecks frequently occur in any work process and can lead to delays and diminished efficiency. There are several Kanban tools and techniques available for managing bottlenecks and improving flow, such as limiting WIP, identifying and resolving blockers, and employing expedite lanes to prioritize urgent work.
By effectively managing bottlenecks, you can ensure that work is completed promptly and efficiently.
Improving your processes
Continuous improvement is a fundamental principle of Kanban, which involves regularly reviewing and analyzing your work process to discover areas for improvement. This might entail conducting retrospectives, examining metrics, and seeking feedback from team members and stakeholders.
By continuously enhancing your process, you can reduce waste, increase efficiency, and deliver higher-quality work.
Adapting Kanban for various contexts
While Kanban has been successfully applied across different contexts, it may need adjustments to cater to the specific needs and requirements of each context.
Employing Kanban in diverse fields
Kanban can be employed in a variety of fields, including software development, healthcare, and marketing. While the core principles of Kanban remain consistent, the specific techniques and tools used might differ depending on the context.
