CMMI / SPICE based process improvement

The purpose of this paper is to identify the relationship between the process improvement approaches of CMMI and ISO/IEC 15504 SPICE. It explains mapping between the two methodologies and outlines how both provide a roadmap to achieve the desired process improvement level. The study provides the effect of each method and detailed insight into the methods. The paper also provides the insight into the two approaches for the organizations interested in choosing the process improvement approach that best meets their needs. It helps in identifying the most widely accepted process improvement approach between the two approaches (i.e., CMMI and ISO/IEC 15504 SPICE) and identifies the reasons to choose the one over the other.
