The team I was previously on tried to use Scrum and seemed to naturally fall into a similar model to Kanban; we got rid of what helped, and stopped doing what didn't. It was an amazing relief, especially since Scrum sprints and the numbers just weren't working.

Sadly, our Scrumlessness was found out and it was implemented again shortly before I left. Morale was dropping steadily on the team already (unrelated reasons), reimplementing the parts we already knew didn't work was a bummer, and the Scrum leader talked down to me when I tried to advocate for the team.
