Abstract
Software effort estimation is the measurement of work and resource required to develop a software system for a particular period. Cost can be determined using effort as cost is directly proportional to effort. Software cost estimation is one of the most difficult jobs in project planning especially in its early phase. In earlier proposed cost estimation models, cost estimation is done with more than 20 parameters at the early conceptual phase and if input is not defined using logical approach, the results of estimation are unpredictable. Using too many cost drivers or parameters make cost estimation process lengthy and complex. In our proposed study, we will highlight on the pros and cons of different cost estimation methods. Then we will look forward to work on making a simple system with minimum set of parameters that can be easily identified at an early stage while considering all possible aspects such as accuracy, simplicity etc.
