Introduction to Kanban

Kanban is an Agile framework that manages work using a visual board. Teams see every task at a glance instead of tracking work through long status reports.

The Origin of Kanban

Kanban began inside Toyota's car factories. Workers used physical cards to signal when a part needed restocking. The word kanban means signboard in Japanese. Software teams later adopted the same visual signal idea to manage their own work.

Core Idea Behind Kanban

Kanban asks teams to visualize their work, limit how much they do at once, and manage the flow of tasks smoothly. These three ideas work together to reduce overload and reveal problems early.

Visualize Work -> Limit Work in Progress -> Manage Flow

Continuous Flow

Kanban does not use fixed time periods like sprints. Team members pull a new task whenever they finish a current one. Work flows continuously rather than in batches.

Starting with What You Have

A team can apply Kanban directly on top of its current process. Kanban does not demand new roles, new meetings, or a complete restart. Teams simply add visibility and limits to their existing workflow.

Layman's Example

Think of a coffee shop counter. Baristas accept a limited number of orders at the espresso machine at once. A new order waits until a finished drink leaves the machine. This steady flow keeps the counter from getting overwhelmed.

Key Takeaway

Kanban improves an existing workflow by making work visible and controlling how much happens at once. The next topics explain the board, the limits, and the metrics that make this approach work in practice.
