Then just start running kanban. Don’t publicize it, don’t make a big deal about it, just start doing it with your team. Frame it as a short experiment with the team, and start trying it. Keep iterating on it until you’re confident it works. Have the courage to keep at it for a while, and also the courage to stop doing it if it doesn’t work after a month or two. Use the team’s health and throughput metrics to ground your decision about whether it’s working.
