SOFTWARE PROJECT ESTIMATION METHODS: A REVIEW

Abstract

Project planning is one of the most important activities in software projects. Poor planning often 
leads to project failure and dramatic outcomes for the project team. Whenever estimates are made, we look 
into the future and accept some degree of uncertainty as a matter of course. Although estimating is as much 
art as it science, this important activity need not to be conducted in a haphazard manner. If cost and effort are 
determined pessimistic in software projects, suitable occasions can be missed, whereas optimistic predictions 
can be caused to some resource losing. Nowadays software project managers should be aware of the increasing 
of the project failure. The main reason for this problem is imprecision of the estimation. The objective of this 
paper is to provide a comparative study of several existing methods of software project estimation technique 
and their aspects.
