Agile Project Management

With Agile approaches, the project is seen as a series of relatively small tasks conceived and executed as the situation demands in an adaptive manner, rather than as a completely pre-planned process.

The assumption from day one is that the only thing you can count on is constant change. Changes will occur throughout the project process that make it impossible to precisely define the traditional variables of time, cost, and scope up front. Therefore the focus is on value delivered and changes are expected, in fact even embraced, throughout the project.
