How do the approaches of Kanban and Scrum differ in software development project management?

Kanban and Scrum are two popular project management approaches in software development, both belong to Agile, but have different principles and practices.

Kanban:

• Focuses on visualizing the workflow using a Kanban board, where tasks move across columns (e.g., "To Do", "In Progress", "Done").
• No fixed iterations or sprints; work is continuous.
• Limiting work in progress (WIP) helps prevent overload.
• Flexible and adaptive, suitable for projects with constantly changing requirements.

Scrum:

• Divides work into fixed iterations — sprints (usually 2-4 weeks).
• At the beginning of each sprint, a set of tasks is planned that the team commits to completing.
• Clear roles: Product Owner, Scrum Master, development team.
• Regular meetings: sprint planning, daily stand-ups, review, and retrospective.

Overall, Scrum is more structured and suitable for teams that want to work on a clear schedule with regular feedback. Kanban is more flexible and suitable for processes with a continuous flow of tasks and changing priorities.
