Introduction
Kanban is a visual approach for managing and optimizing work processes. It originated as a scheduling system for Toyota’s production line in the 1940s and has since been adapted for use in various industries and types of work. Kanban focuses on using visual signals to control and improve work flow, grounded in several essential principles. In this article, we will delve into what Kanban is, how it functions, and how it can be applied in different contexts.
Meaning of Kanban
Kanban is a Japanese term that translates to “signboard” or “billboard.” Within the sphere of work management, it refers to a visual system that employs cards or other markers to represent work items and monitor their progress through a process.
Kanban operates on the principle of “pulling” work through the system, as opposed to “pushing” it from one phase to another. This means that work is only started when there is adequate capacity to handle it, rather than simply adding more tasks to an already overburdened system.
History
Kanban was initially developed by Taiichi Ohno, an engineer at Toyota, in the late 1940s. Ohno sought to create a way to optimize the flow of materials within the manufacturing process and reduce waste. He introduced a basic card system to signal the need for materials and regulate production.
Over time, the Kanban system was improved and adapted to other areas of the production line, eventually finding its way into other industries and types of work.
Kanban principles
Kanban is built on several key principles, including visualizing work, limiting work in progress (WIP), managing flow, making process policies explicit, implementing feedback loops, and continuously 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 explore how these principles are applied in practice using Kanban boards, WIP limits, metrics, and other tools and approaches.
Setting up a Kanban system
In order to establish a Kanban system, you need to grasp your workflow, create a Kanban board, identify work items, apply WIP limits, and outline how work is pulled through the system. This section will cover each of these elements in more depth.
Understanding your workflow
The initial step in devising a Kanban system is comprehending your workflow. This requires mapping the phases of your process, detecting bottlenecks or inefficiencies, and ascertaining the primary metrics for assessing progress and performance.
By understanding your workflow, you can tailor a Kanban system to your distinct needs and objectives.
Designing a Kanban board
A Kanban board is a visual depiction of your workflow, usually divided into columns representing the process stages (such as “To Do”, “In Progress”, and “Done”). The Kanban board can be either physical or digital and can be modified to fit the particular needs of your team or organization.
The board should be straightforward and easy to use, providing a clear view of the status of work items at any moment.
Choosing work items and categorising them
For effective use of a Kanban system, it’s necessary to select work items and categorize them based on type, priority, and other relevant factors. This can be done using cards or other markers on the Kanban board.
Categorizing work items in this way allows for prioritization, more effective management, and ensures that the appropriate work is being carried out at the correct time.
Establishing WIP limits
WIP (work in progress) limits are a vital aspect of Kanban, as they help to avoid overloading the system and ensure that work is executed in an efficient and timely manner. WIP limits are generally established for each step of the process, making sure that there aren’t too many work items in progress at once.
By imposing WIP limits, you can minimize multitasking, enhance flow, and more easily detect bottlenecks.
Determining how work is pulled through the system
The last step in implementing a Kanban system is to determine how work is pulled through the system. This includes developing rules and policies for transitioning work items from one stage to the next, as well as ensuring that all team members comprehend and adhere to these rules.
By adopting clear rules and policies, you can effectively manage workflow and guarantee that tasks are completed consistently and efficiently.
Using Kanban to manage work
Once a Kanban system is in place, the next step is to utilize it to effectively manage your work. In this section, we’ll discuss some best practices for managing work with Kanban, including tracking progress, addressing bottlenecks, and refining your process.
Monitoring progress with metrics
A key advantage of Kanban is the visibility it offers into the status of work items at any given moment. To fully benefit from this visibility, it’s important to establish metrics that aid in tracking progress and pinpointing areas for improvement.
These metrics can include lead time (the amount of time a work item takes to move from its inception to completion), cycle time (the time needed to complete one iteration of a process), and throughput (the pace at which work items are completed).
Managing bottlenecks and flow
Bottlenecks are common in any work process and can result in delays and diminished efficiency. There are several Kanban tools and techniques for managing bottlenecks and enhancing flow, such as limiting WIP, identifying and resolving blockers, and utilizing expedite lanes to prioritize urgent work.
By effectively managing bottlenecks, you’ll ensure that work is completed efficiently and in a timely manner.
Continuous improvement
Continuous improvement is a fundamental principle of Kanban and entails regularly reviewing and analyzing your work process to discover areas for improvement. This might involve conducting retrospectives, examining metrics, and gathering feedback from team members and stakeholders.
By continuously improving your process, you’ll be able to decrease waste, boost efficiency, and deliver higher-quality work.
Adapting Kanban to other contexts
While Kanban has been effectively applied across various contexts, it might require adaptation to meet the specific needs and requirements of each context.
