A probabilistic model for optimal insurance contracts against security risks and privacy violation in IT outsourcing environments

Day by day the provision of information technology goods and services becomes noticeably expensive. This is mainly due to the high labor cost for the service providers, resulting from the need to cover a vast variety of application domains and at the same time to improve or/and enhance the services offered in accordance to the requirements set by the competition. A business model that could ease the problem is the development or/and provision of the service by an external contractor on behalf of the service provider; known as Information Technology Outsourcing. However, outsourcing a service may have the side effect of transferring personal or/and sensitive data from the outsourcing company to the external contractor. Therefore the outsourcing company faces the risk of a contractor who does not adequately protect the data, resulting to their non-deliberate disclosure or modification, or of a contractor that acts maliciously in the sense that she causes a security incident for making profit out of it. Whatever the case, the outsourcing company is legally responsible for the misuse of personal data or/and the violation of an individual’s privacy. In this paper we demonstrate how companies adopting the outsourcing model can protect the personal data and privacy of their customers through an insurance contract. Moreover a probabilistic model for optimising, in terms of the premium and compensation amounts, the insurance contract is presented.     

IT outsourcing and firm-level performance: A transaction cost perspective

We analyzed the effect of the level of low asset specificity IT outsourcing on firm-level financial performance. We used transaction cost economics (TCE) as the theoretical basis to explain the effect of the level of network and telecommunication services outsourced on financial performance. An analysis of 1444 Integrated Healthcare Delivery Systems revealed that higher levels of network and telecommunication services outsourced were associated with superior financial performance. Specifically, each additional network and telecommunication service outsourced resulted in an average $3,120,000 in savings, a 25% increase in profit. In addition, increases in IT budgetary expenditures were found to be associated with increased financial performance. Our study provided preliminary support for the use of asset specificity to guide outsourcing decisions. In particular, IT activities that have become commodities (having ‘low specificity’) should be outsourced to improve the firm's financial performance.

Psychological Contract and Turnover Intention in the Information Technology Profession

The recruitment and retention of Information Technology (IT) professionals continue to concern organizations and researchers. We employ psychological contract theory to examine how unmet expectations may influence psychological contract breach and turnover intention. The results of a survey of IT professionals indicate four factors contributing to IT workers’ perceptions of psychological contract breach including perceived supervisor support, emotional dissonance, work exhaustion, and salary. Further, autonomy moderates the relationship between psychological contract breach and turnover intention.     

Firm strategic profile and IT outsourcing

IT outsourcing research has often been at the transaction level, focusing on the role of the characteristics of the IT activities as the antecedents of outsourcing decisions. The present study extends past research efforts examining the relationships between organizational level variables—in particular the business strategy—and the decision to outsource. Results show that prospectors and analyzers are more aggressive in their use of outsourcing for IT operations. However, no differences between the behaviour of the different strategic groups were found for maintenance activities, suggesting that these activities are too far from the core of the organization to be influenced by strategic profile.

Exploring complexity and contradiction in information technology outsourcing: A set-theoretical approach

Effectively managing Information Technology outsourcing (ITO) requires integration of conceptually distinct and sometimes contradicting factors. For instance, ITO “best practices” for cost reduction can inhibit a firm’s innovativeness. To address these challenges, we build on governance and capability perspectives and employ a set-theoretic approach to examine ITO practices in 27 firms. Our exploratory study reveals four distinct ITO configurations, of which three lead to positive outcomes and one leads to negated-outcomes. Detailed contracts appear to be a necessary condition for cost reduction but can also be an impediment to strategic innovation; and firms can consider a “best-of-breed” strategy to overcome this tension. Our findings call for more attention to both transaction-based and portfolio-based governance to enable flexibility for innovation while retaining rigor and risk mitigation for cost reduction.

Assessing the strategic value of Information Technology: An analysis on the insurance sector

Even though companies today are well aware of the pitfalls in making IT investments and that many IT applications have become commodities, IT projects still fail. Obviously IT has a strategic value to firms but they have not determined how IT management capabilities and IT governance schemes explain commonalities and differences in their use of IT.     

A Process-Centered IT ROI Analysis with a Case Study

In order to achieve a meaningful IT ROI (Returns of Investment) analysis while taking into account the unique business processes of each industry, we should conduct research into a system to evaluate the effect of investment. In this paper, through careful consideration of the characteristics of the banking industry, a study on IT ROI is conducted from the perspective of business process. The process-centered IT ROI model for analysis discussed here consists of seven phases. The suggested model is explained and verified with a case study of a finance company that we shall call A.     

Analyzing IT maintenance outsourcing decision from a knowledge management perspective

IT outsourcing is a complex and opaque decision problem. Managers facing a decision about IT outsourcing have difficulty in framing what needs to be thought about further in their discourses. Framing is one of the most crucial steps of human decision making and needs to be assisted to better understand a decision situation. In this research, we examine a number of decision primitives in the context of an IT outsourcing decision situation. We demonstrate how the decision primitives can be employed so that managers can probe deep to better understand a decision situation and to establish a decision basis. In the organizational setting, we exemplify the use of the decision primitives in relation to the perceived outsourcing implications for the managers looking for assistance in accommodating a knowledge management perspective on IT outsourcing. Consequently, we induce insight and a guideline on how to use knowledge management for effective outsourcing in one of the leading financial institutes in Europe.

An investigation of factors that influence the duration of IT outsourcing relationships

Past studies in the IT outsourcing area have examined the management of IT outsourcing relationships from a variety of perspectives. The present paper extends this line of research. In this study, we take a multi-theoretic perspective to explore factors that determine the duration of continuing IT outsourcing relationships between vendor and client firms. Five ex-ante and two ex-post factors that may influence relationship duration were examined in this study. Data for this study were collected using a nationwide survey. To investigate the dynamics of continuing outsourcing relationships through repetitive contracts, we performed survival analysis using an accelerated failure-time (AFT) model. Four factors are found to have a significant relationship with relationship duration as hypothesized. However, three factors, of which two are ex-post factors, are found to not have a significant impact on outsourcing relationship duration. Implications and contributions of the study are discussed.     

Strategic dependence on the IT resource and outsourcing: A test of the strategic control model

Using resource dependency theory (RDT), this research analyzes how organizations control their information technology resources to improve organizational performance. According to RDT, organizations must manage their dependency on external organizations and limit external dependencies when resources are considered critical. The current study proposes and tests a portion of a Strategic Control Model positing that managers seek to control important, strategic resources in order to create value for the firm and to avoid dependency on external entities. Utilizing a research design that captured extensive quantitative data on the control of IT functions and services, the research team gathered 5 years of data on 54 business units (BUs) in 27 global companies located in seven countries. Study examined the linkages of these 54 BUs to firm performance. Locating the Extent of Control within the firm in cases where the firm depends on IT as a strategic resource proves to be a good explanation for effective decisions leading to higher performance. Viewing IT as a strategic resource alone does not lead to positive business unit outcomes, but the moderating influence of Extent of Control is found to establish the complex statistical relationship with business unit performance. For these reasons, it is critical that a theoretically grounded firm-wide process for decisions on locating IT control is in place to capture business value.

An empirical investigation of information technology structure, control and corporate governance

In a study involving 72 large publicly-held organizations, the relationships between information technology (IT) structure, control, and corporate governance were examined. Despite the fact that some have called centralized systems electronic dinosaurs, many companies are turning to this traditional approach because it does offer one thing that decentralized systems generally lack, namely, control. The results indicate that information technology structure (centralized vs. decentralized) is strongly related to management equity ownership and to concentration of stock holding. For example, an organization where top executives and managers own a relatively high percentage of the company's stock possesses a more centralized information technology structure than an organization with a relatively lower percentage of management ownership. This means that user departments in the latter have more control over their IT functions than users in the former. Conversely, companies with a high level of stock concentration have a more decentralized IT structure. In addition, the research revealed a statistically significant relationship between a company's equity to debt ratio and the level of IT centralization.
