CHAPTER 3
COST ESTIMATION
Cost estimation define as the approximate judgement of the costs for a project. It will never be an exact science because there are too many variables involved in the calculation for a cost estimate, such as human, technical, environmental, and political. It involves a significant human factor can never be exact because humans are far too complex to be entirely predictable. Software development for any fair-sized project will inevitably include a number of tasks that have complexities that are difficult to judge because of the complexity of software systems.

The accurate estimation of software development costs is a critical issue to make the good management decisions and accurately determining how much effort and time a project required for the researchers. There are many software cost estimation methods available. No method is necessarily better or worse than the other, in fact, their strengths and weaknesses are often complimentary to each other. To understand their strengths and weaknesses is important when you want to estimate your projects.
