IT infrastructure capabilities and IT project success: a development team perspective

In this research we investigate how IT infrastructure capabilities are related to IT project success from a development team perspective. We first conduct an extensive literature review and summarize the insights to suggest an IT infrastructure base model. Drawing upon several other bodies of literature, particularly the psychology literature, we then build upon the base model to propose an integrative research model for IT project success that considers both actual and perceived effects of IT infrastructure capabilities. This research model argues that (1) teamwork quality mediates the effect of technical and human IT infrastructure capabilities on IT project success, and (2) team perceptions of both IT infrastructure and team capabilities shape team perceived likelihood of project success, which subsequently affects team commitment that is crucial to IT project success. We also propose a direct-effect model that directly links all constructs to IT project success so that we can test the efficacy of our proposed research model by comparing all three models. We then collect empirical data (n = 91) through an online survey of CIO/CTOs and team leaders. All three models are evaluated and compared using the partial least squares method. The results show strong support for the proposed research model except for two IT infrastructure components. We discuss the practical and theoretical implications of the findings, and suggest several ways this research can be extended.     

Enterprise architecture,IT effectiveness and the mediating role of IT alignment in US hospitals

Despite the possible benefits of implementing healthcare information technologies, successful implementation of effective healthcare information technology is constrained by cultural and regulatory concerns and technical obstacles encountered when establishing or upgrading an organisation's enterprise infrastructure. In this paper, we advance Ross' four‐stage model of enterprise architecture maturity as a valuable IT resource for helping healthcare organisations sustain a competitive advantage. We use partial least squares (PLS) structural equation modelling to analyse survey data from 164 US hospitals at different stages of EA maturity. Our results provide evidence that enterprise architecture maturity directly influences the effectiveness of hospitals' IT resources for achieving strategic goals. Further, enterprise architecture maturity indirectly influences the effectiveness of IT resources when IT alignment is incorporated as a mediating variable. We discuss the implications of our findings for research and practice and suggest opportunities for future research.     

Strategic context and patterns of IT infrastructure capability

The importance of a firm's information technology (IT) infrastructure capability is increasingly recognised as critical to firm competitiveness. Infrastructure is particularly important for firms in industries going through dynamic change, for firms reengineering their business processes and for those with multiple business units or extensive international or geographically dispersed operations. However, the notion of IT infrastructure is still evolving and there has been little empirically based research on the patterns of IT infrastructure capability across firms.We develop the concept of IT infrastructure capability through identification of IT infrastructure services and measurement of reach and range in large, multi-business unit firms. Using empirical case research, we examine the patterns of IT infrastructure capability in 26 firms with diverse strategic contexts, including different industry bases, level of marketplace volatility, extent of business unit synergies and the nature of firm strategy formation processes. Data collection was based on a combination of quantitative and qualitative methods with multiple participants.More extensive IT infrastructure capability is defined as a combination of more IT infrastructure services and more reach and range. More extensive IT infrastructure capability was found in firms where: (i) products changed quickly; (ii) attempts were made to identify and capture synergies across business units; (iii) there was greater integration of information and IT needs as part of planning processes; and (iv) there was greater emphasis on tracking the implementation of long term strategy. These findings have implications for both business and technology managers particularly in regard to how firms link strategy and IT infrastructure formation processes.     

IT infrastructure services as a requirement for e-learning system success

Evaluation of e-learning systems success is an essential process in managing and developing these types of systems. There are still arguments about the factors can be used to evaluate the success of e-learning systems. Inadequate attention has been paid to investigate the role of IT infrastructure services as a foundation to create the success of e-learning systems. The focus of this study is the role of IT infrastructure services in terms of the success of e-learning systems. A model is proposed which includes five constructs: IT infrastructure services; perceived usefulness; user satisfaction; customer value; and organizational value. A quantitative study was conducted at an Australian University, with survey responses from 110 Academic staff members and 720 students who use the e-learning system. The empirical study confirmed that an IT infrastructure services is a valid and reliable construct to measure e-learning systems success. In addition, this study provides evidence of the critical role of IT infrastructure services in the success of e-learning systems via its significant effect on perceived usefulness, user satisfaction, customer value, and organizational value.     

Can ITIL contribute to IT/business alignment? An initial investigation

Strategic alignment has been viewed as one of the main concerns of management and IT executives. Organizations have realized that in order to achieve competitive advantage, IT needs to be strategically aligned with business objectives. Strategic alignment enables organizations to choose IT applications that meet their needs and as a result, to enhance their profitability and reduce costs. Despite the importance of this matter and a large body of literature written on this subject, it has not yet been identified how it can be successfully achieved and maintained. This paper attempts to provide insight on this matter by investigating an initiative called Information Technology Infrastructure Library (ITIL), which ensures the effective and efficient delivery of IT services. The intention of this research was to identify how effective ITIL was in improving alignment between IT and business objectives. The Strategic Alignment Model (SAM) developed by Henderson and Venkatraman was used for this research. This consists of four parts: IT strategy; business strategy; organizational infrastructure and processes; and IS infrastructure and processes. By placing ITIL in the internal domain of the model as a substitute for the IS infrastructure and processes it has been identified that it has the ability to impact the other three main areas of the model and as result enables alignment between all the four parts of model to be achieved. In addition to the above an empirical study has been conducted in order to further investigate the ability of ITIL in achieving alignment between IT and business objectives. Four participants have been interviewed from three organizations ranging from education and banking to the IT sector. The results of the research indicate that ITIL has potential as an effective approach in achieving alignment.     

Determinants of perceived usefulness of e-learning systems

E-learning systems are increasingly essential in universities, schools, government departments and other organizations that provide an education or training service. The objective for adopting e-learning systems is to provide students with educational services via electronic channels. The focus of this study is on the impact of IT infrastructure services and IT quality on perceptions of usefulness of e-learning systems. A model is proposed which includes five constructs: IT infrastructure services, system quality, information quality, service delivery quality, and perceived usefulness. A quantitative study was conducted at an Australian university with 720 survey responses from students who were enrolled in online courses. The results suggest that IT infrastructure services play a critical role in generating information with high quality, enhancing the aspects of e-learning system quality, and improving service delivery quality. The impact of IT infrastructure services, system quality, and information quality on perceived usefulness is fully mediated by service delivery quality. Universities need to be aware of the critical impact of IT infrastructure services and consider how investment in these services could improve system and information quality, service delivery quality, and the usefulness and success of e-learning systems.     

A cross-national analysis of eHealth in the European Union: Some policy and research directions

This study analyzes the relationship among eHealth profiles across 27 European Union Member States. It builds on prior research that uses multivariate statistical methods to provide a cross-country analysis on two dimensions: ICT penetration and availability compared with eHealth access and usage among health professionals. Based on the quantitative indicators/metrics used in our study, our results reveal that four distinct country groupings emerge as frontrunners, followers, leapfroggers and laggards. Frontrunners combine a strong ICT infrastructure with relatively high adoption of eHealth technologies. Our study suggests that a one-size-fits-all approach to health IT is not recommended for EU Member States because policy-makers at the national level need to develop an eHealth roadmap that reflects national, regional and local conditions that go beyond technical imperatives.     

IT2000: A critical appraisal of Singapore's state-wide strategic planning process for information technology

In April 1992, the Singapore Government announced its information technology (IT) vision and plan for the next 15 years to turn Singapore into ‘an intelligent island’, providing a strategic regional switching centre for expertise, goods, services and information. At the heart of this plan is a national information infrastructure that would capitalize on information as a key factor of production and an important ingredient for enhancing the quality of life of its people. Code named ‘IT2000’, the plan was developed by 60 senior managers at the National Computer Board in 1991 with participation and inputs from about 200 business and industry leaders, domain experts and academics. This paper describes the background of Singapore's drive into the information age, the IT2000 planning process, the roles of various participants and the main recommendations of the plan. An evaluation of IT2000 is made in terms of its objectives, its unanticipated results and its impacts on industry participants. Implications and lessons are drawn for strategic IT planning at the national or sectoral level.     

Eignet sich Cloud-Computing als Instrument zur Förderung ökologischer Ziele?

Cloud computing has been introduced as a promising information technology (IT) that embodies not only economic advantages in terms of increased efficiency but also ecological gains through saving energy. The latter has become particularly important in view of the rising energy costs of IT. The present study analyzes whether necessary preconditions for accepting cloud computing as a new infrastructure, such as awareness and perceived net value, exist on the part of the users. The analysis is based on a combined research framework of the theory of reasoned action (TRA) and the technology acceptance model (TAM) in a cloud computing setting. Two consumer surveys, the one to elicit beliefs and the second to gain insight into the ranking of the variables, are employed. This study uses structural equation modeling (SEM) to evaluate the hypotheses. The results indicate support for the proposed research framework. Surprisingly however, the ecological factor does not play a role in forming cloud computing intentions, regardless of prior knowledge or experience. Empirical evidence of this study suggests increasing efforts for informing actual and potential users, particularly in respect to possible ecological advantages through applying the new IT infrastructure.     

Examining the role of information technology in cultivating firms’ dynamic marketing capabilities

Most prior research has investigated an organization's dynamic capabilities in general and overlooked their effect on critical business functions. Our study considered the role of IT in improving firm's dynamic marketing capabilities. We developed a model consisting of market orientation, IT infrastructure capabilities, and the use of IT in customer relationship management (CRM). With data collected from 135 manufacturing and service firms in Taiwan, our results supported most of our hypotheses. Our results showed important direct effects of a firm's market orientation, use of IT to support CRM, and the functionality of IT infrastructure capabilities on its dynamic marketing capabilities.     

Digital Preservation in Grids and Clouds: A Middleware Approach

Digital preservation is the persistent archiving of digital assets for future access and reuse, irrespective of the underlying platform and software solutions. Existing preservation systems have a strong focus on Grids, but the advent of cloud technologies offers an attractive option. We describe a middleware system that enables a flexible choice between a Grid and a cloud for ad-hoc computations that arise during the execution of a preservation workflow and also for archiving digital objects. The choice between different infrastructures remains open during the lifecycle of the archive, ensuring a smooth switch between different solutions to accommodate the changing requirements of the organization that needs its digital assets preserved. We also offer insights on the costs, running times, and organizational issues of cloud computing, proving that the cloud alternative is particularly attractive for smaller organizations without access to a Grid or with limited IT infrastructure.     

From a resource rich country to an information rich society: An evaluation of information technology policies in Malaysia

Abstract

Malaysia is a resource rich country and a major socio‐economic force in the Asia‐Pacific region. Historically, the economy of Malaysia was based on agriculture and natural resources. In its efforts to transform Malaysia to a developed and industrialized country, the government started to focus on industry and high technology in the 1980s. A key area of focus was Information Technology (IT). The government chose to adopt several policies with respect to the supply and demand sides of IT instead of a national IT plan¹. The policies addressed IT infrastructure, education and training, research and development, use of IT in the public sector, and fiscal incentives. These IT policies and the broad economic and industrial policies implemented during this period had a positive influence on demand for IT products and services, number of IT professionals, number of telephones per 100 population, and IT production and use. This experience has laid a firm foundation for formulating more definitive national IT policies for the 1990s and in achieving the government's objective of transforming Malaysia into a developed and information rich society by 2020.     

Optimising resource costs of cloud computing for education

There is a growing interest around the utilisation of cloud computing in education. As organisations involved in the area typically face severe budget restrictions, there is a need for cost optimisation mechanisms that explore unique features of digital learning environments. In this work, we introduce a method based on Maximum Likelihood Estimation that considers heterogeneity of IT infrastructure in order to devise resource allocation plans that maximise platform utilisation for educational environments. We performed experiments using modelled datasets from real digital teaching solutions and obtained cost reductions of up to 30%, compared with conservative resource allocation strategies.     

Managing the Reliable Design of an Enterprise IT Network Infrastructure

Today's businesses are more and more dependent upon their information technology (IT) infrastructure. Therefore, the managers are aware of the huge costs associated with data loss (and recovery) and invest millions of dollars in special equipments in order to increase the reliability of their IT systems. Thus, the focus in this article is on the practical modalities of designing a reliable IT network infrastructure in an enterprise. In this direction an algorithm has been developed that is a hybrid between classic greedy and simulated annealing that search for the most reliable IT network infrastructure meeting the imposed budget cost constraints and the enterprise managers' decisions constraints. A key point of the proposed solution is the way in which the enterprise managers are involved in the estimation of the relative importance of their interconnections between their business's data centers. Furthermore, the algorithm presented in this article has been evaluated in the case of a retail enterprise for addressing the business's demands for a higher reliability of their IT network infrastructure.     

Digital hermeneutics: an outline

The purpose of this paper is to give an outline of digital hermeneutics understood as the encounter between hermeneutics and digital technology, particularly the Internet. In the first part, I want to raise the attention of IT researchers and hermeneuticists to the theoretic and practical relevance of the encounter of their areas of research that are sometimes considered as incompatible to each other. There is still a lot of translation work to be done in order to get these two cultures come closer to and profit from each other. The second part of the paper deals with the foundation of digital hermeneutics on what I call—following Heidegger’s and Vattimo’s paths—digital ontology as opposed to digital metaphysics.

Factors influencing the information security behaviour of IT employees

ABSTRACT

Although non-IT employees have received considerable attention in security research, IT employees have received scant attention, even though they might be very different to non-IT employees. To address this gap, we developed a model based on protection motivation theory, deterrence theory and the theory of reasoned action. We conducted a quantitative survey of IT employees to determine which factors influenced their information security behavioural intentions. Although sometimes contrary to findings regarding non-IT employees, the influential factors were: self-efficacy; and perceived impact of a potential event; with cues to action exerting a significant influence on that perceived impact. These results have significant academic and practical implications.     

How information technology influences opportunity exploration and exploitation firm’s capabilities

Understanding how and why some firms have proficiency in exploring and exploiting opportunities is a cutting-edge research problem. Our central thesis is that information technology (IT) performs a key role in firms’ opportunity exploration and exploitation. We test the proposed theory using partial least squares path modeling on a combination of survey and secondary data from 203 Spanish firms. We find that: (1) IT infrastructure provides the foundation to build business experimentation and the flexibility to sense and explore business opportunities; and (2) IT-enabled business flexibility helps firms to develop the operational proficiency to exploit opportunities and increase their performance.
