Many IT projects experience problems because the development time and/or resource requirements are
underestimated. Which of the following techniques would provide the GREATEST assistance in developing an
estimate of project duration?

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 andmodeling.
