摘要：Collaborative software proves to be a key-element in achieving common goals in many areas of activity, such as education or healthcare. The aim of this article is to provide a reliable framework for building collaborative portals for education. These portals represent virtual places for student cooperation and community build-up in order to create reliable and efficient projects, guided by the teachers from the Computer Science Departments and optimized using Criticality Analysis. This paper presents a new software project duration estimation model for enhanced project risk assessment and quality control in the field of distributed collaborative project development. The Extended Metrix model is a stochastic model for software project duration estimation and risk analysis using Monte Carlo simulation over an activity graph. The model is endowed with Criticality Analysis features for enhanced control of the project development process.
