A.
Function point analysis

B.
PERT chart

C.
Rapid application development

D.
Object-oriented system development

Explanation:

A PERT chart will help determine project duration once all the activities and the work involved with

those activities are known. 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 files, etc. While this will help determine the size of
individual activities, it will not assist in determining project duration since there are many
overlapping tasks. Rapid application development is a methodology that enables organizations to
develop strategically important systems faster while reducing development costs and maintaining
quality, while object-oriented system development is the process of solution specification and
modeling.
