The document compares and contrasts time boxing and kanban. Time boxing refers to allocating a specific amount of time to complete a task or result, like 15 minutes for a daily stand up meeting. Kanban involves using a board to visualize and track the flow of work. Time boxing is recommended if a team struggles with breaking down work, while kanban is better if a team is interrupt-driven as it allows people to see their workload and reduce handoffs. The document suggests teams evaluate their needs to determine whether time boxing or kanban is the best approach.
