摘要：It is very hard to estimate software development effort accurately. So far, no model has proved to be successful at effectively and consistently estimating software development effort or cost. So it is useful to research a particular model for a particular type of project. A new model for small organic project is proposed for software effort estimation. This model is based on actual project data and well-established theories, using Gauss-Newton model to calibrate the parameters of the COCOMO model, using Fuzzy logic models to maintaining the merits of the COCOMO model. In particular, this model has been successfully used in some small project, and has demonstrated great potential to predict software cost more accurately.
