Kanban and Scrum are both popular project management methodologies that can help teams stay organized and deliver projects on time. However, there are some key differences between the two that are important to understand.

Kanban boards are used to visualize the flow of work in a process, and they are often used in manufacturing and software development to help teams manage their workload and identify bottlenecks in their processes. Kanban boards typically include columns that represent the different stages of a process, and cards or sticky notes are used to represent individual tasks. The key feature of Kanban boards is that they are highly visual and allow teams to quickly see where work is currently and where it needs to go next.

Scrum boards, on the other hand, are used to manage sprints, which are short, time-boxed periods during which teams work to complete a set of tasks or deliver a specific piece of functionality. Scrum boards typically include columns for "To Do", "In Progress", and "Done", and they are used to track the progress of tasks and identify any obstacles that may be preventing the team from meeting their sprint goals.

One major difference between Kanban and Scrum is that Kanban boards are designed to be flexible and adaptable, while Scrum boards are more rigid and prescriptive. Kanban boards are often used in environments where the team is working on an ongoing, unpredictable workflow and needs to be able to adjust their processes as needed. Scrum boards, on the other hand, are more suited to environments where the team is working on a defined set of tasks that need to be completed within a fixed timeframe.

Another key difference between Kanban and Scrum is that Kanban boards are used to visualize the flow of work, while Scrum boards are used to track the progress of tasks. Kanban boards are often used to identify bottlenecks in a process and make improvements, while Scrum boards are used to ensure that the team is making steady progress towards delivering a piece of functionality.

In summary, while Kanban and Scrum boards may look similar at first glance, they serve different purposes and are used in different ways. Kanban boards are highly visual tools that help teams manage ongoing, unpredictable workflows, while Scrum boards are more prescriptive tools that help teams stay on track during sprints.
