This work is generally performed in the construction and transition phases, although there may be situations where it
is useful to perform it as early as the elaboration phase. It is typical for beta testing to be the primary focus for
iterations in which it is conducted, As such this activity will typically be preceded by integration and build
activities focused on enabling the beta test work. This activity itself will typically begin part-way into the
iteration and may continue until the end of the iteration.
This activity can be considered optional. It is most appropriate in situations where the product being built is
unprecedented or where the product will be shrink-wrapped and made available for sale commercially.
Generally, products will either be beta tested or final acceptance tested (at the installation site), but not
both.
