In software engineering research area, cost/effort estimation is one of the most important issues. Effort estimation accuracy will affect the availability of resource allocation and task scheduling. This article discusses the need for new metrics and models to estimate the effort and duration for Web development projects. It then describes a new size metrics, presents two novel methods (WEBMO+ and VPM+), based on WEB model (WEBMO) using Web objects instead of SLOC and Vector Prediction Model (VPM), to fast estimate the development effort of Web-based information systems. We also empirically validate the approach with a four projects study. The results indicate that the approach provides a mechanism to measure the size of software systems, classify software systems, and estimate development effort early in the software life cycle to within +/-20 percent across a range of application types. In contrast with other existing methods, WEBMO+ and VPM+ uses raw historical information about development capability and high granularity information about the system to be developed, in order to carry out such estimations. This method is simple and specially suited for small or medium-size Web based information systems.
