Kanban Methodology

Kanban is a visualization-based method used in software development and business management. The term "kanban," meaning "visual card" in Japanese, was first implemented within the Toyota Production System. In the software world, it was adapted and popularized in the early 2000s by David J. Anderson.

Kanban aims to make workflow visible in order to identify bottlenecks, delays, and inefficiencies in processes. Unlike Scrum, like Kanban is not iterative but is based on a continuous delivery model.

Core Principles

1. Visualize the Current Process:
2. Workflow is typically displayed through a Kanban board, which includes columns such as "To Do," "In Progress," and "Done."
3. Limit Work in Progress (WIP):
4. The number of tasks that can be worked on simultaneously in each column is restricted. This prevents workflow congestion.
5. Manage the Flow:
6. The movement of tasks through the system is continuously monitored and optimized.
7. Encourage Improvement:
8. The team is encouraged to continuously improve and adapt processes (Kaizen philosophy).

Use of Kanban in Software Development

• It can be integrated with existing processes with minimal disruption.
• Planning is not bound to strict time boxes.
• Team members pull tasks from the board and progress at their own pace.
• The process can be flexibly updated as requirements change.

Advantages

• Offers a simple and practical system.
• Adapts to teams of any size.
• Facilitates workload management.
• Enables analysis of efficiency and delivery times.
• Promotes a culture of continuous improvement.

Limitations and Challenges

• Due to the absence of a defined rhythm (such as a sprint cycle), it demands greater team discipline.
• Continuous changes may lead to loss of focus.
• Inadequate application of WIP limits can cause bottlenecks in the process.
