Kanban

What is Kanban?

Kanban is a management technique that visualizes work progress and boosts team efficiency. Originating from Toyota’s automobile factories, the term comes from Japanese “kanban” (signboard). Today it’s adopted across software development, marketing, sales, and numerous industries.

In a nutshell: Kanban divides work into “To Do,” “In Progress,” and “Done” boxes, instantly showing who does what work and when completion occurs.

Key points:

• What it does: Visualize work flow, identify bottlenecks
• Why it’s needed: Early delay detection enables improved team efficiency
• Who uses it: Software development teams, project managers, sales teams

Why it matters

Born from Lean philosophy, Kanban transforms not just tools but organizational culture. Traditional approaches require managers periodically checking progress; problems hide during gaps. Kanban means everyone views the same board (physical or digital), detecting and responding to issues immediately.

Teams adopting Kanban report 20-30% delivery compliance improvement and dramatically reduced status reporting time. This occurs because unnecessary meetings vanish and execution improves. Additionally, Kanban combines well with modern approaches like Design Thinking and Agile, fostering continuous improvement culture.

How it works

Kanban’s basic structure: three elements—“cards,” “columns,” and “WIP limits.”

Start by writing all tasks on cards (sticky notes or digital). Each card shows “what,” “who,” and “when.”

Next, arrange cards left-to-right across multiple columns. Standard: “To Do,” “Doing,” “Done.” Teams may add “Review,” “Testing,” etc.

Most importantly: “WIP limits.” Set ceilings on work counts. “Doing column max: 3 tasks” means finishing or advancing current work before starting new. This accelerates overall flow.

Kanban resembles library checkout systems. Return deadline arrives before borrowing new books within your limit. Similarly, finishing tasks precedes new tasks when WIP limits apply.

Real-world use cases

Software development teams

Developers work on features; card status instantly shows. Identifying “bug fixes stuck in Doing”—other developers can help, ensuring delivery deadlines.

Marketing campaign operations

Manage article workflow as “planning,” “writing,” “editing,” “publishing-ready.” Article publication timing clarifies. Noticing “editing bottleneck”—improve resource allocation.

Customer support

Manage inquiries as “received,” “responding,” “complete.” Prevent missed responses; ensure fast resolution. Monitor high-priority inquiry status.

Benefits and considerations

Kanban’s greatest benefit: simple visibility. Complex calculations unnecessary; anyone understands instantly. Also, flexibility allows customization to team situations.

Important caution: Kanban alone doesn’t enable long-term planning like Scrum’s sprints. Multi-project parallel management requires adjustments. Also, overly strict WIP settings reduce team productivity; regular review matters.

Frequently asked questions

Q: Must Kanban Boards display physically?

A: No. Trello, Jira, Asana work equally. Digital tools actually fit modern remote work better. However, same-office teams benefit from physical boards—better visibility supports team cohesion.

Q: What WIP limits should we set?

A: “Doing column limit = team member count” is typical starting point. Adjust through actual operations.

Q: Can Kanban alone manage large projects?

A: Kanban emphasizes flow continuity, unsuitable for multiple independent project parallel management. Combine Scrum, use multiple Kanban boards, or adjust.
