Cost estimation of software projects is a very important activity in software process development for shaping how much effort and time software projects required. A successful software project depends mainly on an accurate cost estimation which is one of the most critical factors of good management decisions. Our observations have shown that it is best to use a number of different estimating techniques or cost models, and then compare the results before determining the reasons for any of the large variations. Accurate cost estimation of software projects is not easy to do because it needs more experience and more knowledge about the nature and key features of projects. Incorrect cost estimations of projects in software development houses of this country prompted us research about the reasons for this problem. The review results combined with other knowledge provide support for recommendations for future software cost estimation research, including: increase the breadth of the search for relevant studies , conduct more studies on estimation methods commonly used by the software industry, increase the awareness of how properties of the data sets impact the results when evaluating estimation methods. A Software Cost Estimation affects nearly all management activities, including project bidding, resource allocation and project planning. The primary conclusion is that no single technique is best for all situations, and that a careful comparison of the results of several approaches is most likely to produce realistic estimates.
