Answer: B
Function point analysis is a technique for determining the
size of a development task based on the number of function
points. Function points are factors such as inputs, outputs,
inquiries, logical internal file, etc. While this will help
determine the size of individual activities, it will not
assist in determining project duration since there are many
over-lapping tasks. A PERT chart will help determine project
duration once all the activities and the work involved in
the activities are known. Rapid application development is a
methodology that enables organizations to develop
strategically important systems faster while reducing
development costs and maintaining quality, and
object-oriented system development is the process of
solution specification and modeling.
