ABSTRACT
Traditional software models are directed towards large monolithic software development projects. Software development can be viewed through a structured programming paradigm. The projection of software costs is made at a general system level for these models. The frequency at which the updated or newer version of Calculating the candidate commercial off the shelf software is made in order to be effectively used in a larger system. For processes like project planning, project budgeting, and project bidding the estimation of effort in software projects is considered fundamental. This effort estimation is taken seriously in software companies because inaccurate planning and budgeting can lead to serious consequences. The functional scope required for the development of a software system can be defined with the help of the use case model. In the target software system, the number of actor types involved will be counted and this number of actor types will be the product with a weighting factor.
