Exploring Capability Maturity Models and Relevant Practices as Solutions Addressing IT Service Offshoring Project Issues

Abstract

Chi-square test was applied to test all the hypotheses using p= 0.05 as the critical significance level: H1: The relationship between adopting CMM/CMMI industrial standards and the IT offshoring issues. H2: The relationship between CMM/CMMI industrial standards Maturity level achieved and the frequency of issues experienced. H3: The relationship between MM/CMMI industrial standards practices and the frequency of issues experienced. H4.1: The relationship between adopting CMMM/CMMI industrial standards and the project success factors. H4.2: The relationship between CMM/CMMI industrial standards maturity levels achieved and the project success factors. H4.3: The relationship between CMM/CMMI industrial standards practices and the project success factors. Hypothesis 1Hypothesis 1 tests the relationship between four CMM/CMMI models and the frequency of issues experienced by the client companies. Hypothesis 1.1 tests the relationship between companies that applied only CMMI for Development (DEV)/Services(SVC) and companies that did not apply any quality standard model and the 17 issues of offshoring IT projects; Hypothesis 1.2 tests the relationship between companies that applied only CMMI for Acquisition and companies that did not apply any quality standard model and the 17 issues of offshoring IT projects; Hypothesis 1.3 tests the relationship between companies that used only People CMM and companies that did not apply any quality standard models and the 17 issues of offshoring IT projects; and Hypothesis 1.4 tests the relationship between companies that applied only TSP and companies that did not apply any quality standard model and the 17 issues of offshoring IT projects.Bonferroni's correction was used when multiple comparisons were drawn from a single sample. Hypothesis tests the 17 issues 4 times with 4 industrial standards. Bonferroni correction (adjusted) pvalue= 0.05/(17*4) = 0.05/68 = 0.0007352 H1.1 There is a relationship between adopting CMMI development/services and the IT offshoring issue. H1.2 There is a relationship between adopting CMMI acquisition and the IT offshoring issues. H1.3 There is a relationship between adopting CMM people and the IT offshoring issues. H1.4 There is a relationship between adopting CMM TSP and the IT offshoring issues.Hypothesis 1.1: Adopting CMMI-DEV/SVC and IT offshoring issues H1.1 There is a relationship between adopting CMMI development/services and the IT offshoring issues.1 -Hypothesis 1.1.1 Issue: Over Expenditure due to hidden costs. H1.1 There is a relationship between adopting CMMI development/services and the over expenditure issue. 302The analysis shows a significant relationship between practicing CMMI for Development/Services and experiencing over expenditures for offshored IT projects. The value of chi-square test is 62.468 from table A-H-2 and differences among the observed and expected groups are statistically significant with df=2 and p =.000000.This hypothesis investigates the relationship between practicing CMMI Development/Services and over expenditur...

Exploratory Study of the Adoption and Use of the Smartphone Technology in Emerging Regions: Case of Saudi Arabia

“…Additionally, this response rate is consistent with the response rate of a typical PhD dissertation survey in the field of engineering and technology management, which typically obtains a response rate range from 6.1% to 11.4% [252,257,224]. Therefore, the response rate in this dissertation of 12.8 percent is well within the expected and acceptable range.…”

“…In a number of previous desertions the acceptable score is 4 -Somewhat Closely for relevance and 4-Somewhat Easy for ease of answering questions [219,224]. Accordingly, after incorporating experts' feedback, the goal in this dissertation is to have all surrey questions score above 4 -Somewhat Closely for relevance and 4-Somewhat Easy for ease of answering questions.…”

The MESSIR Flexible Scientific Approach to Requirements Engineering

“…This makes the lecture difficult to design and execute since it implies that the teacher has to select a subset of the KAs to cover in a short time budget, and it also supposes that the teacher is expert in all the KAs which, of course, can rarely be the case; (b) Most of the KA subtopics are covered thanks to Engineering Projects offered in the curriculum. Engineering Economics (12) and Software Quality (29) and, more surprisingly, Software Maintenance (5). This last fact seems in direct opposition with the reality of engineering activities which, for the majority, consists in supporting software evolution and maintenance.…”

“…It is thus interesting to observe industry practice through the capability maturity model in order to better determine the problem of improving software engineering practice. According to available studies [15,[27][28][29], which we have witnessed during our own empirical experience in handling more than 600 internships in industry for bachelor and master students and as expert for the court of justice on conformance questions in trials for the software industry, we can state that: (a) Approximately 3/4 of companies are at level 1 or 2 (initial or repeatable); (b) Among the companies that go for CMMI appraisal, approximately 80% are at or below level 3 (defined) and 20% at level 4 (managed) and 5 (optimizing).…”

The impact of outsourcing information technology services on business operations

“…According to Mckeen and Smith (2009), in the early 2000s, organisations started to realise that they can meet strategic objectives, drive costs down and add capacity by turning to outsourcing. Salman (2014) defined IT outsourcing as 'the turning over of a firm's computer operations, network operations, software development and maintenance or other IT functions or services to a provider for a specified time'. Gorla and Somers (2014) suggested that IS outsourcing annual growth rate is at 14% with the current IT services market value at $746 billion.…”
