How does Kanban differ from Scrum?
Both Kanban and Scrum are popular methodologies within Agile Development used in Software Development. However, they have distinct differences.
1. Framework Structure
Scrum is a structured framework that employs time-boxed iterations called sprints, typically lasting 2-4 weeks. It emphasizes specific roles such as Scrum Master, Product Owner, and Development Team. Kanban, on the other hand, is more fluid and does not prescribe specific roles or time boxes. Its focus is on continuous delivery.
2. Work Visualization
In Kanban, work is visualized on a Kanban board, which displays all tasks in various stages of completion. This allows team members to see bottlenecks and workflow efficiently. Scrum also utilizes a task board, but it resets at the beginning of each sprint, limiting long-term visualization.
3. Flexibility and Adaptability
Kanban is highly flexible, allowing teams to adjust their work processes and priorities continuously. Scrum typically requires teams to commit to a set amount of work during each sprint, making it less adaptable to changes mid-sprint.
4. Workflow Management
Scrum emphasizes delivering a potentially shippable product increment at the end of each sprint, which fosters accountability. In contrast, Kanban focuses on managing work-in-progress (WIP) and optimizing flow, potentially delivering features or updates more frequently.
In summary, while both Kanban and Scrum are Agile methodologies aimed at improving workflow and productivity in software development, their principles and practices distinctly set them apart.
