Abstract: Establishing and improving software process capability is the requirement of the high maturity level of CMM or CMMI, and also a difficult problem of software measurement. This paper discusses the related concepts and issues of software process capability, defines the software process capability indexes, and gives the quantitative solution to establish and improve software process capability by using XmR control chart technique of statistical process control. An example of establishing and improving software process capability is given to illustrate the usage of the quantitative solution.
