Abstract:

To ensure the validity of software project schedule estimation and improve the success rate of software projects, combined with some actual project cases, a quantitative and systemic method of software project schedule validation was studied. A schedule verifying guide was established by modeling. The regression result was found not obvious by validation. It indicates that this guide could only be used to verify, but not used to arrange the schedule. The usage of the schedule verifying guide was studied combined with some actual project cases. In addition to the validity validation of single project, the whole schedule estimation method validity of the organization was studied by modeling based on the collection and statistics of historical data. The actual data indicates that the model can improve and ensure the validity of the schedule estimation result and the estimation method, and can obtain continuous improvements.

Key words: software project, schedule estimation, validity, verifying guide
