I would even argue that points, stories and sprints are not things you need. If you go kanban, you don’t need sprints. You still need to be producing and you probably want to get a feel for complexity so you can prioritize, but that can be done without points.

Stories are also very scrum specific and you can turn them into whatever format you want. I usually still call them stories, but they’re basically just a little card that describes the context (why do want something) and the deliverables (what will be implemented to meet that want).
