A quick Step-by-Step tutorial that will help you get started with Kanban and manage projects with ease in Kanbanize.
The Kanban world is vast and diverse. Ever wondered how so many terms and practices come together in a perfect harmony? Open the Kanban encyclopedia to know it all.
The Kanban method is an advanced set of principles and practices combined with artifacts for visualization of your workflow. At first sight, it seems like a simple way of mapping the stages of your work process, but there is more than half of a century worth of theory and experimentation that brought it to your desktop.
Get to know the Kanban terminology and learn everything about the Kanban concept and the people that developed it in our Kanban Encyclopedia.
The word literally means ‘signboard’ or ‘visual card’. In the late 1940s, it became a term for Toyota’s inventory management system and later evolved as a process management method.
The kanban system originated as a scheduling system for lean manufacturing and just-in-time manufacturing (JIT). It was an inventory-control system used for the supply chain by Toyota’s engineer Taiichi Ohno.
The Kanban Method for knowledge work and service work was formulated by David J. Anderson in 2005. He combined elements of the work of W Edwards Deming, Eli Goldratt, Peter Drucker, and Taiichi Ohno. It incorporates concepts such as pull systems, queuing theory, and flow.
A Kanban board is one of the tools to implement the Kanban method. The board is divided into minimum 3 columns – Requested, In Progress, Done, representing the stages of a process.
Kanban boards can be physical or electronic. The main idea is to visualize the path of tasks from request to completion and see where the bottlenecks are.
Basic Kanban Board
In Kanban, tasks are visually represented by cards. Each Kanban card is a work item, moving through the columns on the Kanban board. Cards contain information about the work item. They are not different in size because the idea is to break a project down to its smallest tasks and complete them quickly.

Swimlanes are the horizontal divisions of a Kanban board, helping to optimize the workflow. The columns represent stages, and swimlanes categorize work. Swimlanes can be used to represent teams, classes of service, priority, etc.
WIP or Work In Progress is the amount of work being started, regardless of the subcolumn, it is currently in.
Setting limits on the work in progress is a strategy to avoid overworking and context switching while focusing on the important things. Applying WIP limits is the second core practice in Kanban and ensures a healthy flow.

There are 7 Kanban Cadences – the cyclical meetings that drive evolutionary change and “fit for purpose” service delivery.
The Portfolio Kanban is a holistic method that aims to improve an organization’s ability to deliver by applying the principles of visualization, limiting work in progress and flow management on a system level.
The main difference between the Portfolio Kanban method and the Team Kanban method is that the Kanban cards on a Portfolio Kanban board are “parents” of one or many Kanban cards that live on the Team Kanban board.
The purpose of the Kanban software is to ensure better visualization of the workflow. In comparison to classical project management software, it provides more flexibility and takes less time to administrate. Kanban software enhances team communication, generates metrics and helps improve processes and increase predictability.
And Optimize Your Workflow.
Kanban metrics are aimed at improving the predictability of the process. The most important to monitor are throughput, WIP, cycle time, and lead time.
Throughput is the number of items, passing through a system or process. According to Little’s Law, Average Throughput = Average WIP divided by average cycle time. The throughput of your team is a key indicator showing whether your process is productive or not.
Cycle time begins at the moment when the new arrival enters “in progress” stage and somebody is actually working on it until it enters Done column.
This is the period between a new task’s appearance in your workflow and its final departure from the system.
The cumulative flow diagram is one of the most useful analytical tools in Kanban systems. Kanban software could provide it as a built-in tool. It tracks the three kanban metrics – throughput, cycle time, and WIP and presents data in a visual and concise way.
Example of CFD
Average Cycle Time = Average Work In Progress / Average Throughput
Little’s law locks the three measures (WIP, throughput and cycle time) together in a unique and consistent way for any system to which it applies.
However, it was originally stated in a slightly different form:
Average Items In Queue = Average Arrival Rate * Average Wait Time
This fact is important because different assumptions need to be satisfied depending on which form of the law you are using.

The second Kanban principle, ‘agree to pursue incremental, evolutionary change’, emphasizes that for the successful implementation there needs to be an agreement on a slow, gentle, evolutionary, incremental approach, otherwise there won’t be the right environment or management support for a Kanban initiative.
Blocker is the reason that blocks a card on the Kanban board. Whatever keeps it from progressing towards completion can be a blocker. Some frequent reasons are “not enough information”, “personal capacity”, “expedite issue”, among others.
Blocker clustering is a technique to analyze blockages. Different reasons for blocked work are grouped and the cause is determined for each group, it becomes like a cluster around it. Clustering emphasizes that blockades have a cost. This is a strategy for improvement and future avoidance of the quantified blockages.
For example, within the two large categories “internal and external blockades”, we often see clusters such as “dependent story”, “missing requirements”, “environment not available” and “product owner not available”.
Cost of Delay is a way of communicating the impact of time on the outcomes we hope to achieve. More formally, it is the partial derivative of the total expected value with respect to time.
Cost of Delay combines urgency and value – two things that are not very easy to distinguishing between. To make decisions, we need to understand not just how valuable something is, but how urgent it is.
Technically, the bracketing of a single WIP limit across the system is known as a CONWIP (for “constant Work-In-Progress”). A CONWIP is a form of pull system and applied within a mature Kanban system and work very well.
The most recent fourth principle of the Kanban Method is ‘encourage acts of leadership at all levels’. Leadership is an important catalyst for changes and people are more likely to improve in a culture of safety and empowerment.
The fourth Kanban practice says ‘make policies explicit’. As the method revolves around a common agreement to pursue incremental and evolutionary change, this is one of the first things to do. Making policies explicit facilitates consensus around improvement suggestions and minimizes the chance of misconceptions and lack of understanding.
The sixth practice of the Kanban Method is fully formulated as ‘improve collaboratively, evolve experimentally (using models/ scientific method)’. If a team has a shared understanding of theories about work, workflow, process, and risk, it is more likely to build a shared comprehension of a problem and suggest improvement actions that can be agreed upon.
There are three useful models suggested by David J. Anderson:
Feedback loops represent the circulation of information and change between the 7 cadences. The relationships are shown visually in the picture above.
Sometimes, teams call their meetings feedback loops for simplicity, although the meaning is truly the interactions between them.
Managing flow is the third Kanban practice that refers to monitoring and measuring flow. Flow is the movement of work items from request to completion.
Fast and smooth flow means that a system is creating value quickly, which is minimizing risk and avoiding the cost of delay and is also doing so in a predictable fashion.
The abbreviation stands for Just In Time. Just-in-time manufacturing/production is a methodology aimed primarily at reducing cycle times within the production system. It originated in Japan, largely in the 1960s and 1970s, and particularly at Toyota.
Kaizen is the Japanese word for “continuous improvement”. It has evolved as a business term in post-WW2 Japan, describing a business practice to improve processes and eliminate waste, most notably in Toyota.
A pull system is a lean manufacturing strategy used to reduce waste in the production process. Components used in the manufacturing process are only replaced once they have been consumed so companies only make enough products to meet customer demand.
In management, it means that no new work is started until started items are finished. When there is capacity, a new item is pulled to ‘In Progress’.
A pull policy within a pull system sets the process requirements – the order in which work is to be pulled, where from, and how much.
The third Kanban principle is ‘respect current roles and positions’. This means not to make changes in the formal structure within an organization when implementing Kanban. It can be applied to the existing process. By agreeing to respect current roles, responsibilities, and job titles we eliminate initial fears.
First Kanban principle states ‘start with what you do now’. The Kanban Method does not require any changes to the process. It is based on the concept that the current process evolves and improves.
The first Kanban practice is to visualize the workflow. This is the primary function of the Kanban board and the best way to obtain information about a process and to analyze the data. This is the first thing needed in order to proceed with the other principles.
Taiichi Ohno was a businessman and an industrial engineer at Toyota, known as the Father of the Toyota Production System, which became the foundation of Lean manufacturing.
Early in his career, he expanded upon the JIT concepts developed by Kiichito Toyoda to reduce waste and started experimenting with and developing methodologies to produce needed components in a timely manner to support final assembly. This way, he developed kanban to improve manufacturing efficiency. He identified the 7 wastes (or Muda in Japanese) of Lean.
“Progress cannot be generated when we are satisfied with existing situations”.
Sakichi Toyoda was a Japanese inventor, industrialist and the founder of Toyota Industries Co., Ltd.
He invented a power loom in 1902 and in 1926 an automatic loom capable of detecting a snapped thread that automatically stopped the loom thus preventing the production of poor quality. This principle of autonomous automation is known as Jidoka principle and became a part of the Lean methodology.
“I’m not talented more than anybody else. I just put lots of efforts and researches.”
David J. Anderson is a thought leader in managing effective technology development. He is a pioneer of the use of kanban systems for improved service delivery in professional services businesses. David Anderson is the originator of the Kanban Method and for improved service delivery and strategy.
“People ask me, “What is the difference between lean and kanban?” Answer: lean is a destination; kanban is a means to get there.”
