Creating and updating Kanban policies requires consideration of your team's context, culture, and capabilities, as well as involving your team in the process. To define your Kanban policies, start by defining the purpose, scope, and roles of your Kanban system. Then, identify the steps and stages of your work process and visualize them on your Kanban board. Set a maximum number of work items that can be in each column or lane at any given time (WIP limit). Establish the conditions and requirements that must be met for a work item to move from one column or lane to another (DoD or exit criteria). Finally, define the indicators and measures that you will use to track and evaluate your team's performance (Kanban metrics). This will help you prevent overloading your system, balance demand and capacity, focus on finishing what you start, ensure quality and completeness of work, monitor and improve workflow, identify and solve problems, and celebrate achievements.
