The present time system software's are complex and cost estimation is required in such type of complex software's. The overall cost of such software's can be reduced by reusing the existing components. The component based software engineering is the technique through which the authors can easily reuse the existing components and able to reduce the overall software cost. They can estimate the overall cost of the system software before development, if the overall cost will be reduced by reusing the existing components then only they can reuse these components otherwise not.
