Kanban is a method used to make work visible and manage it more effectively. Many people know Kanban through boards with columns such as “To Do,” “In Progress,” and “Done.” But Kanban is more than a task board. When used properly, it helps teams identify bottlenecks, reduce overload, and continuously improve processes.
This makes Kanban attractive to many organisations. Whether in production, IT, administration, marketing, service, or project work, Kanban can help make processes more transparent whenever work flows through multiple steps.
Kanban originates from the Lean environment and roughly translates as “signal card.” The method was originally used to manage material flows and align work with actual demand. Today, Kanban is used in many areas, including outside production.
The basic idea is simple: work is made visible, limited, and continuously improved. Teams can see which tasks are waiting, which are currently being worked on, and where work is getting stuck.
A Kanban board visualises the workflow. A simple board consists of three columns: To Do, Doing, and Done. In more complex processes, additional columns may be useful, such as Request, Analysis, Implementation, Review, and Approval.
Each task is represented by a card. This makes it visible how much work is in the system at the same time. If cards start building up in one column, this indicates a bottleneck. The team can then investigate why work is getting stuck at that point.
An important Kanban principle is limiting the amount of work being done in parallel. Many teams are not slow because they do too little, but because they start too many things at the same time. This creates waiting, context switching, and unfinished work.
Kanban uses so-called WIP limits, or Work in Progress limits. When a column reaches its limit, the team does not simply start new work. Instead, they help complete existing work or resolve the bottleneck.
Kanban fits very well with Lean Management. Both approaches aim to reduce waste and improve flow. Kanban makes it visible where work is waiting, where handovers are unclear, and where tasks remain unfinished for too long.
In production, Kanban can manage material flows. In administrative processes, it can make approvals, requests, or processing steps visible. In knowledge work, it helps teams manage priorities and capacity more effectively.
Many organisations introduce a Kanban board and expect processes to improve immediately. That rarely works. A board alone does not improve anything. It makes problems visible. Improvement only happens when the team regularly discusses those problems and takes action.
Kanban therefore requires routines: short coordination meetings, clear rules, responsibilities, and regular reflection. Without these routines, the board can quickly become little more than a digital noticeboard that no one seriously uses.
Kanban supports continuous improvement because it makes process problems visible. Teams can ask: Which tasks remain open for too long? Where does rework occur? Where is information missing? Which work is started too early? Where are responsibilities unclear?
These questions lead to concrete improvements. Perhaps a handover needs to be clearer. Perhaps a column needs a WIP limit. Perhaps entry criteria need to be defined. Or perhaps an approval process is unnecessarily complicated.
Kanban is a powerful tool for visibility and flow. Lean Six Sigma complements it when problems require deeper analysis. If a bottleneck occurs repeatedly, a Green Belt project can help investigate the causes and develop sustainable solutions.
In this way, Kanban can become a starting point for structured process improvement. It shows where problems occur. Lean Six Sigma helps solve those problems systematically.
Kanban helps teams make work visible and manage processes more effectively. Its greatest value does not come from the board itself, but from the conversations and improvements that result from it.
For organisations introducing Lean Management or Lean Six Sigma, Kanban can be a practical starting point: visible, understandable, and closely connected to daily work.
The Lean Six Sigma Company helps teams combine Kanban, Lean Management, and Lean Six Sigma in a practical and effective way.
