A Scrum board
If you're a software developer or a member
of a large team, Scrum could be of most help.
A Scrum board makes room for stories - the general ideas behind all your actions, for sprints
- the things you want to get done within this particular iteration, and for the actual To Do, Doing and Done sections. The idea backing up sprints is that after each one, the final product should be usable.
