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

B. PERT chart

A PERT chart will help determine project duration once all the activities and the work involved in the 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, and object-oriented system development is the process of solution specification and modeling.
