Information Technology Outsourcing (ITO) in terms of the replacement of the in-house production of IT activities by the use of third party suppliers had already started in the 1960s and has increased considerably. For 2013, the Gartner Group expected that the global ITO market would reach a volume of 288 bn US dollars. Until 2017, the market should grow on average about 5.4% yearly. Despite the rich set of experiences companies have already had with ITO, the chances of success are seen as at best 50:50. Currently, the dramatic growth of ITO is accompanied by backsourcing of formerly outsourced IT functions or reports about dissatisfaction and problems with ITO. Scientists put ITO failures or problems down to a lack of modelling of all the possible factors affecting ITO success and demand a specific ITO theory as a basis for better explaining and predicting successes and failures in an IT sourcing context. This thesis takes up this research gap. The aim of this thesis is to develop a novel ITO Model which aids organisations in planning and implementing ITO solutions by guiding them through the ITO process steps of preparation, selection, contract, transition, execution, and post-deal comprising a comprehensive picture of the weighted aspects relevant to ITO success and their interdependencies. In order to achieve this aim, the following objectives were established for this thesis: raising the topical level of scientific knowledge of the last decades about successinfluencing factors in the ITO field based on an extensive literature survey of 48 scientific articles deriving ITO success factors from empirical research work; structuring of this success factor knowledge by the development of two ITO taxonomies (taxonomy of success factors and taxonomy of success factor interdependencies); testing its practical applicability on the basis of 8 real long-running application outsourcing cases in the banking industry; further development of the success factor knowledge by identification of weightings and the temporal relevance of relevant success factors / success factor interdependencies within the ITO process. Design of the novel ITO Model based on the empirical knowledge gained by development of rules for relevant success factors and success factor interdependencies, by arrangement of these rules in temporal order within the ITO process and by assignment of these rules to four levels of environment.

Assessing performance, quality, and excellence in services are critical topics in the literature. As such, this thesis evaluates aspects related to conceptualisations and measurement models across different disciplinary perspectives. This thesis develops, and validates a multiple-item scale for Modelling service excellence in the UK retail banking sector, according to the perceptions of customers. The scale development method follows Churchill’s (1979) well founded process, and is informed by Anderson and Gerbing’s (1988), and Rossiter’s (2002) guidelines. The model estimates whether the hypothesised antecedents are considered valid for identifying banks which provide excellent services. The findings reveal that reputation, rates, innovation, and technology significantly determine service excellence. This thesis was undertaken in a critical timing, between 2007 and 2012. During that time, the economy and particularly, the banking sector faced a major credit crunch and crisis of confidence in the sector per se. The crisis caused banks to rethink their competitive positioning by re-assessing their strengths (Akdag et al. 2011). Hence, initiating a differentiation between quality and excellence in services was essential. Overall, this thesis contributes to the literature by offering an integrated solution to assessing service excellence, from concept definition and differentiation, to scale development and validation. A new definition of services excellence is introduced and components of services excellence are identified. Hence, distinguishing between service quality and service excellence. Furthermore, the relationship between service excellence and its determinants is explored. Based on an updated set of antecedents and corresponding items, the measurement model provided in this thesis is considered as one of the best available options, realised by testing the postulated hypothesis and the alternative model testing.

The main objectives of this study are to demonstrate the significance of customer service quality in the banking sector of Cyprus in order to enable managers in banking organisations to identify the determinants of customer perceptions of service quality and ultimately to provide a method to measure the levels of service quality offered. Therefore, the objectives of this thesis are: • To evaluate the SERVQUAL model and assess whether it can be applied in the context of the Cypriot banking industry, and consequently establish a reliable and valid service quality measurement instrument for Cypriot banks, and • To identify the level of service from banks in Cyprus and detect ways to improve the service quality offered. This study evaluates SERVQUAL dimensions, and more specifically the perceptions side of the instrument, and modifies it through an extensive and in-depth analysis of the literature review published on the topic of service quality and through interviews with bank experts and quality specialists so as to assess its applicability to the banking industry in Cyprus. As a result of this analysis, a modified version of the perceptions’ side of SERVQUAL was constructed as a measurement scale of service quality in the banking sector of Cyprus. Data were collected through customer surveys conducted outside bank branches. Subsequently, the collected data were analysed through tools such as factor analysis, multiple regression analysis, and internal consistency measurement. This analysis helped to prove the validity and reliability of the modified instrument used to measure service quality and revealed the dimensional structure of the service quality construct in the Cypriot banking sector. The major findings of this study suggest a four-dimensional construct derived from 23 items in the questionnaire. These dimensions are employee proficiency, convenience, professionalism and assurance. All four factors are positive and significant predictors of service quality. This result is different from the SERVQUAL and the SERVPERF models as both indicate five dimensions composed of 22 items. The reliability and validity of the scale(s) in this study were fully supported. These results lead to several implications for both researchers and practitioners. For theorists, the results of this study can be used as foundations for further studies, for questionnaire scale development, to further support the use of a single scale and to raise the issue of the non-existence of the ‘tangibles’ dimension, which is not fully discussed in the literature and should be tested in future studies as well. For managers and practitioners this study offers much support for the importance of employees and for a continuous investment in service quality programmes. It also suggests incorporating service quality measurement into branch performance measurement. Finally, the results obtained in this study pose significant challenges to managers and support the idea that practitioners should have a comprehensive view of service quality in banking organizations to accurately measure customer perceptions of service quality.

This study investigates the effective measurement of employee commitment within the Nigerian banking sector. The relevance of the research originates from various research findings that shows that in most organisations, evidence abounds of employees' emotional and physiological distancing of themselves from their organisation even when the pay is highly competitive. In addition, there are also evidences of inconsistencies in research outcomes when Western commitment scale is employed within non-Western organisation. This study is therefore aimed at filling literature gaps on identified inconsistencies from the use of Western scales in measuring commitment in non-Western organisations and also to comprehend employee commitment behaviour in organisations within non-Western culture. In exploring the above issues, this research developed a 28-item, 7-point Likert scaled questionnaire, distributed to 200 participants with a 42% response rate. The research also employed exploratory factor analysis in the form of PCA and Varimax for factor extraction and scale reduction and Cronbach's Coefficient alpha internal consistency measure for reliability assessment. To take the study a step further, the scale was additionally subjected to statistical test using One Way ANOVA, Pearson's Chi-Square test, and Spearman' s rank order correlation in measuring employee commitment behaviours, using two variables: income and age. The outcome from the study was two-fold. The 28 items were reduced to 18 usable items with 3-factor extractions representing three components of commitment. Scale reliability was also measured. The first outcome shows that the scale is indeed a culturally suitable and usable (valid and reliable) scale for the assessment of employee commitment to their organisation in Nigeria with an alpha score of .930, evidence of strong scale reliability. The second outcome was from the test aimed at assessing the behavioural aspect of employee commitment to their organisation in relation to the two variables income and age. The outcome shows that the higher income earning Nigerian employees (employees within the income band 1.1 million and above), and employees within the age group 31-35 are likely to be less committed to their organisations than their counterparts. The study concludes with the view that to effectively measure employee commitment to organisations in non-Western Nigerian cultures, requires the development and use of an appropriate and culturally motivated usable and suitable (consistent and dependable) scale. The conclusions are also discussed in terms of the links between income, age and commitment. It identified that high income and age are not necessarily indicators of commitment; rather some factors associated with culture might have stronger influence on employee expression of commitment to their organisation.

The purpose of this study was to examine the relationship between market orientation and business performance mediated by marketing resources and moderated by contextual factors. The study also examined the extent to which the conceptual model was a good fit to the sample data. A quantitative approach was used to test if there was a significant relationship between market orientation, marketing resources, and business performance. For the purpose, a cross-sectional survey was carried out to obtain data pertaining to market orientation, marketing resources, contextual factors and business performance. The unit of analysis of the study was banks consisting of 3 public and 15 private banks. A sample size of 507 consisting of 492 branch managers and 15 top level marketing managers was used in the survey. With a response rate of 87.97%, 446 questionnaires were collected of which 377 were used for data analysis. A SEM was used to test the extent to which the theoretical model fits the sample data. Mediation analysis was used to test the indirect effect of market orientation on business performance and hierarchical regression analysis was used to test whether the relationship was moderated by market dynamism, competitive intensity, and government regulation. Finally, an independent t – test was used to examine the statistical variations between public and private banks in terms of market orientation, marketing resources, and business performance. The confirmatory factor analysis revealed that the modified model was fit with the observed data in terms of chi-square and the individual indices. The total effect of market orientation on business performance was moderate with a 0.36 regression coefficient. The indirect effect was high with a 0.91 regression coefficient where complete and inconsistent mediation was found due to suppression effect. The moderation analysis revealed that the interaction effect of market dynamism, competitive intensity, and government regulation was not statistically significant. Finally the result showed that there was a statistically meaningful difference between public and private banks in terms of market orientation, marketing resources, and business performance. Banks in Ethiopia shall strive to segment the market, differentiate their services, and build a strong brand with clear identity. Banks in Ethiopia shall also build on their marketing resources to enhance their business performance. / Business Management / D.B.L.

The role that banks as key intermediaries play in the modern economy activities is unquestionable, it is admitted that banks remain one of the key financial intermediaries that provide a variety of services in the economy of every state. However, not all financial intermediaries have a significant impact on modern economies, only a stable and profitable banking sector can adequately play the role of financial intermediary in economy. The bank, as an intermediary in the modern economy must be profitable, and this profitability depends on a number of factors that are referred to in this study as determinants of bank profitability. The effect of internal and external determinants of the bank profitability in South Africa is the main focus of this study. It utilized annual time series internal and external data for the period 2001 to 2013. Quantitative approach methodology using secondary data and panel data technique to measure the impact of the determinants was used in the study. The sample consists of nine banks, followed for 12 years and sampled annually. The results for bank-specific consist of four statistically significant variables such as bank size, non-interest income and non-interest expense and credit risk and four non-significant variables (equity capital, loan, saving deposit, fixe term deposit) also the industry-specific consist only one significant variable (market concentration) while macro-economic determinants consist of three non-significant variables (economic growth, inflation, and lending interest rate). In conclusion, the empirical result shows that the bank specific factors are directly controlled by the Management thereby it has a positive correlation to the bank profitability while the industry specific (market concentration) also positively affects the bank profitability. However, the macroeconomic variables which are beyond the scope of management control were non-significant to profitability but show positive sign. Therefore, the variables which are significant affect positively the bank profitability, and the non-significant variables affect the bank profitability negatively. The findings were consistent with mixed results found in prior literature. / Business Management / M. Com. (Business Management)
