Professional Scrum with Kanban builds upon the core Scrum values to enhance flow and effectiveness within the team. The relevant values are:
* Courage: Encourages team members to address issues, experiment with changes in the workflow, and make adjustments transparently, even when facing uncertainty.
* Focus: Enhances the team's ability to concentrate on achieving the Sprint Goal and flow of work items by using Work in Progress (WIP) limits and other Kanban practices.
* Openness: Promotes an open environment where the team transparently shares information on work progress, obstacles, and opportunities for improvement, which is key for continuous inspection and adaptation in Kanban.
These values directly support the empirical process control and continuous improvement principles of Kanban
