Based on the specific elements in terms of process area, project, practice and relevant methodologies, which were adopted from Capability Maturity Model Integration(CMMI), this paper studied feasible appraisal program that combined the CMMI implementation cycle model into entire software process, therefore, the index system and measurement model in measuring the quality of software developing p...

Process maturity reference frameworks such as ISO/IEC 15504 and the Capability Maturity Model Integrated (CMMI) seek to assist software process improvement (SPI) efforts by prescribing a roadmap for improving the capability of the development process. However, such frameworks are not widely adopted in the practice [1], [2], especially in smaller software development organisations where the deve...

In this study, to estimate the process capability index

A zero-inflated Poisson (ZIP) distribution is commonly used for modelling process data with single type of defect, and developing appropriate tools instituting statistical control manufacturing processes. However, in reality, such scenarios are very common where more than one defect can occur. For example, occurrences defects like solder short circuits (shorts) absence (skips) on printed circui...
