Should Cards Move Backward?

The whole concept behind using the word “flow” in “workflow” is that work keeps moving forward. Sounds nice, right? But we all know it's a little ambiguous in practice. What about those times when cards seem to need to move backward on the board? Like when QA finds a bug—should the card move back to Dev? 

To answer that question, we first have to remember why the columns on the Kanban board exist in the first place: to be stages of transformation—not roles or specific activities, per se. And with that teaser, you can probably guess what our answer is. If not (or even if you have), listen to this episode to find out!
