Computer information project planning is one of the most important activities in the modern software development process. Without an objective and realistic plan of software project, the development of software process cannot be managed effectively. This research will identify general measures for the specific goals and its specific practices of Project Planning Process Area in Capability Maturity Model Integration (CMMI).   CMMI is developed in USA by Software Engineering Institute (SEI) in Carnegie Mellon University. CMMI is a framework for assessment and improvement of computer information systems. The procedure we used to determine the measures is to apply the Goal Questions Metrics (GQM) approach to the three specific goals and its fourteen specific practices of Project Planning Process Area in CMMI.
