With GTD or Getting Things Done David Allen developed a method aiming at a higher efficiency and effectiveness of self-organization.
GTD is based on two principles:
In this connection GTD uses a multiphase system to deal with the to-dos. In general it is proceeded as follows:
There is a large number of tools and extensions for all platforms supporting this method.
The method itself is not bound to a software tool. The complete process can also be carried out with notes and/or a whiteboard.
To-dos make it not possible to learn from the completed tasks. There is only an active or a completed state. As a result a finer segregation would not reasonably work, at least not without additional attributes or tags. The method is strongly focused on the single person and therefore unqualified for collaborative working with a delegation of tasks, collaborative learning and the support of a pull-oriented working method.
