There is no such thing as best practice. There is only best fit, based on principles in your context.
Welcome to the Rough Guide to Kanban
The rough guide to Kanban is a way to help teams self coach improvement. It's based on collaboration, a simple improvement loop (based on the kanban values) and a poster of options to experiment with. The poster can be used as a visual indicator of what practices teams are using, experimenting with or have discarded.
