This document discusses using visualization techniques to improve processes through Kanban methods. It provides examples of different types of Kanban boards that can be used, including: - Traditional Kanban boards that visualize the workflow and work items moving through different stages. - Non-traditional boards like risk Kanban boards that visualize risks and priorities, and portfolio Kanban boards that manage multiple teams' work at a higher level. The document emphasizes that visualization makes processes and flows explicit, which is necessary for understanding problems and improving collaboratively over time. A variety of real case examples of different Kanban board configurations are presented.
