What are the Difference between Scrum and KANBAN

Scrum and Kanban are both popular agile frameworks used for project management and product development, but they have distinct characteristics. Here are some key differences between Scrum and Kanban:
1. Methodology:

Scrum: It follows an iterative and incremental approach. Work is organized in fixed-length iterations called sprints, typically two to four weeks long. Scrum provides a defined set of roles, ceremonies, and artifacts.
Kanban: It is more of a continuous flow system without fixed iterations. Work items move through a visual board with columns representing different stages of the workflow.

2. Work Structure:

Scrum: Teams commit to a set of work for each sprint, and changes to the committed work are discouraged during the sprint. The work is planned in the sprint backlog and delivered in a potentially shippable product increment.
Kanban: There are no fixed timeboxes or sprints. Work is pulled continuously, and there are no predefined commitments for a specific period. Work items can be added or removed at any time.

3. Roles:

Scrum: Defines specific roles such as Scrum Master, Product Owner, and Development Team. Each role has defined responsibilities within the framework.
Kanban: Typically has no predefined roles. It allows flexibility in team structure, and team members can take on different roles as needed.

4. Planning and Estimation:

Scrum: Requires detailed sprint planning and estimation for the work to be done during the sprint. The team commits to delivering a specific set of features during the sprint.
Kanban: Generally does not require detailed upfront planning or estimation. Work is pulled based on capacity and priority, and new work can be added at any time.

5. Continuous Improvement:

Scrum: Emphasizes inspecting and adapting through regular sprint reviews and retrospectives. Continuous improvement is built into the Scrum framework.
Kanban: Also encourages continuous improvement, but it does not prescribe specific events like sprint reviews or retrospectives. Teams can evolve their processes organically.

6. Visualizations:

Scrum: Uses burndown charts and sprint backlogs to visualize progress and work remaining during a sprint.
Kanban: Utilizes a Kanban board to visualize the flow of work through various stages, providing transparency into the status of each work item.

In summary, while both Scrum and Kanban are agile methodologies, they have different approaches to planning, execution, and continuous improvement. The choice between Scrum and Kanban depends on factors such as the nature of the project, team dynamics, and the level of flexibility required in the development process. Some teams also adopt a hybrid approach, combining elements of both Scrum and Kanban to suit their specific needs.
