Kanban is one of the most widely known methods for managing tasks, activities, and workflows. As workloads increase and organizations deal with more demands, visual approaches like Kanban can become increasingly valuable across many different areas.
After all, managing work can be complex. Without some type of system or method, tasks can be forgotten, while others may become stuck somewhere in the process.
This does not just affect individual activities. A bottleneck in one stage can create risks for the entire process, preventing subsequent activities from moving forward.
Despite the complexity of everyday work, Kanban offers a relatively simple, visual, and highly practical approach.
In this article, we’ll explain how Kanban works and how you can use it to better organize your work. More importantly, we’ll look beyond task management and explore how Kanban can support process management, productivity, and continual improvement.
What Is Kanban?
Kanban is a visual method used to manage and improve the flow of work.
Its origins are strongly associated with Taiichi Ohno and the Toyota Production System (TPS), where visual signals and cards were used to help control production according to actual demand.
The Japanese word kanban can be translated as something similar to a card, sign, or visual signal.
At its most basic level, Kanban can be understood by visualizing work in three simple stages:
- To Do
- Doing
- Done
By organizing tasks according to these stages, teams can visualize their workflow and use that information to better understand and manage the work.
Kanban boards can be physical—using a wall, whiteboard, or cards—or digital, using task and project management software.
This makes Kanban a powerful visual management tool that can be used by individuals as well as larger teams.
For more complex environments, however, the basic three-column structure may not be enough. In these situations, the workflow can be expanded and adapted to reflect the actual stages of the process.
How Do You Use Kanban?
The simplest way to start is to create three columns representing the status of your work:
- To Do: Tasks that need to be completed but have not yet been started.
- Doing: Tasks that have already started but have not yet been completed.
- Done: Tasks that have been completed and can be removed or archived.
This simple workflow allows you to quickly understand what needs to be done, what is currently being worked on, and what has already been completed.
But the real value comes from analyzing what you see.
When looking at the board, you can start asking questions such as:
Why hasn’t this task started yet?
Why has this activity remained in “Doing” for so long?
Why are several tasks accumulating at the same stage?
Why hasn’t a completed task moved to the next stage of the process?
Questions like these transform the Kanban board from a simple task list into a useful management tool.
This simplicity is one of the reasons Kanban has expanded far beyond manufacturing. Today, visual workflow management can be found in offices, manufacturing operations, healthcare organizations, software development teams, service companies, and many other environments.
Customizing Kanban for More Complex Workflows
The three-column model is intentionally simple, and it may not be enough for every workplace.
The good news is that Kanban can be adapted to represent the actual stages of your workflow.
One common approach is to add columns corresponding to specific process stages.
Imagine an order fulfillment process such as:
Order Received > Parts Picking > Product Assembly > Order Packaging > Shipping
In this example, we have five process stages, so our Kanban board could have five corresponding columns.
Each order moves across the board as it progresses through the process.
Once the order is received, it moves to parts picking. From there, it moves to assembly, packaging, and finally shipping.
This makes it much easier to see how orders are flowing through the process.
More importantly, it can reveal where work is accumulating.
And that information can support better decisions about capacity, resources, priorities, and process improvement.
Using Kanban to Make Better Decisions
Using the example above, imagine that Product Assembly consistently takes longer than the other stages.
Over time, you may begin to see work accumulating in the assembly column.
This is a visual indication of a potential bottleneck.
If you manage a team of 20 people, simply dividing those employees equally across five stages—four people per stage—may not be the most effective approach.
Instead, resource allocation could reflect the complexity, workload, capacity, and time required at each stage.
For illustration, the team could be distributed as follows:
- 1 employee for Order Receiving
- 5 employees for Parts Picking
- 10 employees for Product Assembly
- 3 employees for Order Packaging
- 1 employee for Shipping
This is only an example, of course. The appropriate allocation would depend on the actual process data and operational requirements.
The important point is that Kanban helps make the flow of work visible.
If work begins accumulating at a particular stage, managers can investigate the cause and determine the appropriate response.
That might involve reallocating employees, changing priorities, improving the process, addressing capacity constraints, or adding resources when justified.
Instead of making decisions based purely on assumptions, teams can use what they see in the workflow to better understand where attention is needed.
Practicality, Efficiency, and Effectiveness Above All
The greatest advantage of Kanban is its simplicity.
By making work visible, we can more easily understand what needs to be done, what is currently in progress, and what has already been completed.
But Kanban can provide much more value than simply organizing tasks.
Once we can see the workflow, we can begin to identify bottlenecks, recognize excessive accumulation of work, allocate resources more effectively, and identify opportunities for improvement.
Kanban can also be adapted to different operational realities.
A team may begin with three simple columns or create a more detailed workflow with process-specific stages, Work in Progress (WIP) limits, explicit workflow policies, and other criteria appropriate to the process.
Perhaps one of Kanban’s most valuable lessons is that management does not necessarily need to become more complicated to become more effective.
Sometimes, the first step is simply to make the work visible, understand how it is flowing, and use that information to continually improve the process.
If tasks are frequently forgotten, activities keep piling up, or processes seem to get stuck without anyone knowing exactly why, it may be time to put the workflow on a board.
Start simple. Visualize the work. Monitor the flow. Identify where work accumulates. Then, as you better understand the process, make the necessary adjustments.
Ultimately, Kanban can be much more than a way to organize tasks.
Used effectively, it can become a valuable tool for improving workflow, increasing productivity, identifying bottlenecks, supporting continual improvement, and making management clearer and more effective.
