Can you explain the principles of operation and the main idea of the Kanban methodology in task management?

Kanban is a task management methodology based on visualizing the workflow and limiting the number of tasks in progress at the same time. The main idea is to create a continuous flow of work, minimizing unfinished tasks and increasing team efficiency.

Principles of Kanban:

• Visualization of work: tasks are displayed on a board (Kanban board) as cards that move across columns representing stages of the process (e.g., "Planned", "In Progress", "Done").
• Limiting work in progress (WIP - Work In Progress): limits are set on the number of tasks in each column to avoid overload and improve quality.
• Flow management: the speed of task progression through the process is analyzed to identify bottlenecks and improve the process.
• Clear rules for transitioning tasks between stages.

Example of a Kanban board:

| Planned | In Progress (max 3) | Testing | Done |
|---------|---------------------|---------|-------|
| Task 1  | Task 2              |         |       |
| Task 3  |                     |         |       |

Kanban helps manage tasks flexibly, respond quickly to changes, and improve team productivity.
