One of the first things assembled when we embark on a new project is a list of things to do. Everyone loves a list! Projects often start as a to-do list, jotted down on a piece of paper. For small pieces of work, this may be all you need. As soon as you have more than a trivial set of tasks you’ll need a better system than a simple list and for agile teams, we have Scrum’s product backlog.
