There is an international cricket governing body that ranks the expertise of all the cricket playing nations, known as the International Cricket Council (ICC). The ranking system followed by the ICC relies on the winnings and defeats of the teams. The model used by the ICC to implement rankings is deficient in certain key respects. It ignores key factors like winning margin and strength of the opposition. Various measures of the ranking concept are presented in this research. The proposed methods adopt the concepts of h-Index and PageRank for presenting more comprehensive ranking metrics. The proposed approaches not only rank the teams on their losing/winning stats but also take into consideration the margin of winning and the quality of the opposition. Three cricket team ranking techniques are presented i.e., (1) Cricket Team-Index (ct-index), (2) Cricket Team Rank (CTR) and (3) Weighted Cricket Team Rank (WCTR). The proposed metrics are validated through the collection of cricket dataset, extracted from Cricinfo, having instances for all the three formats of the game i.e., T20 International (T20i), One Day International (ODI) and Test matches. The comparative analysis between the proposed and existing techniques, for all the three formats, is presented as well. [ABSTRACT FROM AUTHOR]

Capability Maturity Model Integration (CMMI) is a framework known for improving the quality of processes on consistent basis. This paper makes an attempt to explore, analyze and describe the impact of CMMI in terms of return on investment (ROI) for the IT industry. An IT organization who has acquired a maturity level of CMMI 2 is taken as case study. At first, in reference to the level of applied CMMI, a thorough study is completed. Afterwards the luxuries and limitations are studied and explored with reference to organizations applying the monetary terms using ROI framework. Finally, the presented research highlights the key benefits and difficulties in switching to CMMI from conventional quality assurance. [ABSTRACT FROM AUTHOR]
