Other than having a Kanban board with swim lanes by ‘Classes of Service’, you may also want to use other swim lanes categorization scheme. Like… swim lanes by teammates … to see how their respective work items are flowing … see how the work is flowing to meet the demand. Are there some bottlenecks (constraints) occurring along the flow? Where is it? What are you going to do about it? Set WIP limits? Improve entry and exit Policies in each phase? Thoughts?
