This section provides guidance on how to use the technique in an effective way.
Without effective time boxing, focus can be lost and things will run out control.
Much of what is discussed here is to do with planning, control and keeping a clear
focus on what actually has to be delivered at the end of the time box. It is for this
reason that there is a very close relationship between time boxing and the clear
prioritization of deliverable. In addition to this, there is also an important reliance
on an ability to estimate the complexity and duration of the tasks to be undertaken.
It is also vital that whoever is actually undertaking the work within the time box
should be involved in the development of these estimates.
