Risk-based model for the web-based systems development progress assessment and the criteria for assessing of software development projects progress were developed. Criterias values can overestimate the complexity of individual modules and the whole project, and then adjust the development process. It will reduce the deviation from the scheduled date of delivery of the project, thus reducing the risk of violations of scheduling. The proposed model provided the basis for informational technology for web-oriented systems risk-based functionality assessment. The proposed information technology is directed at reducing the risk of project development, monitoring progress of the development of web-systems and conformity assessment evolutionary prototype and the schedule for the current iteration.
