What is the fundamental difference between Scrum and Kanban?

Scrum and Kanban are two popular project management methodologies in Agile, but they have fundamental differences:

• Scrum is an iterative approach with fixed time frames (sprints), usually 2-4 weeks. Scrum has clear roles (Scrum Master, Product Owner, team), regular ceremonies (sprint planning, daily stand-ups, retrospectives), and a fixed set of tasks per sprint.

• Kanban is a more flexible and continuous workflow without fixed iterations. The main tool is a board with columns reflecting process stages, and limiting the number of tasks in each column (WIP — work in progress). Kanban does not require specific roles or ceremonies.

In summary, the main difference:

• Scrum works with fixed iterations and roles, focusing on planning and regular meetings.
• Kanban focuses on visualizing the workflow and limiting concurrent tasks, without strict time frames.
