IT service provider organizations need both IT service management (ITSM) and IT service governance (ITSG) to ensure successful service provision for their customers. However, current service science literature has not adequately addressed how these activities differ from each other. Focusing solely on IT service management and ignoring service governance aspects may cause difficulties in measuring the performance of service management, defining and deploying the roles and responsibilities of service management, allocating the resources for right service improvements and adopting the service-oriented process culture. The research problem of this study is: How does IT service management differ from IT service governance? The main contribution of the study is a framework for IT service governance and a roadmap of IT service management frameworks and standards that can be utilized in establishing IT service governance activities. The theory-based framework is validated in an IT service change management case study with five Finnish IT service provider organizations. The results of this study may be used by top management, service directors and the IT service managers of IT service companies to better identify different aspects of IT service management and IT service governance. 相似文献

SOA是以提高流程柔性为基本目标的IT架构方法,业务服务粒度在SOA项目中起着关键的作用,该文研究目的在于解释业务服务粒度与流程柔性间的基本关系。首先分析了SOA环境下业务流程的范围柔性和响应柔性两个关键维度并给出定义;基于服务元素和流程协调的研究给出了这两个维度的量化计算方法;构建了业务服务粒度的分析模型并进行量化分析。结果表明SOA环境下随着业务服务平均粒度的增大,流程的范围柔性将逐渐减小,流程的响应柔性将逐渐增大,而流程的整体柔性度将先逐渐增长,达到一定的程度后再逐渐下降。 相似文献

Effective information technology (IT) governance mechanisms: An IT outsourcing perspective 总被引:1,自引:0,他引:1
Effective IT governance will ensure alignment between IT and business goals. Organizations with ineffective IT governance
will suffer due to poor performance of IT resources such as inaccurate information quality, inefficient operating costs, runaway
IT project and even the demise of its IT department. This study seeks to examine empirically the individual IT governance
mechanisms that influence the overall effectiveness of IT governance. Furthermore, this study examines the relationship of
effective IT governance, the extent of IT outsourcing decisions within the organizations, and the level of IT Intensity in
the organizations. We used structural equation modeling analysis to examine 110 responses from members of ISACA (Information
Systems and Audit Control Association) Australia in which their organizations have outsourced their IT functions. Results
suggest significant positive relationships between the overall level of effective IT governance and the following mechanisms:
the involvement of senior management in IT, the existence of ethic or culture of compliance in IT, and corporate communication
systems. 相似文献

This study investigates the relation between the maturity of IT governance processes and the IT governance disclosure of firms. Furthermore, it examines whether the strategic role of IT in an industry induces systematic variation in IT governance disclosure. Based on a content analysis of annual reports and a field survey on the maturity of the implementation of COBIT processes, the results demonstrate a role of IT governance frameworks in stimulating accountability and transparency via enhanced external reporting of relevant IT information to external stakeholders, in particular in settings where the strategic role of IT is high. 相似文献

Research on the strategic management of Information Technology (IT) resources has mostly focused on the oversight provided by the management team as a means to increase organizational performance. In recent years, boards of directors have also increased their involvement in IT matters, and various theoretical lenses suggest that this oversight too has the potential to influence organizational performance. Hence, this study synthesizes the resource-based and contingency views of MIS with corporate governance theories, and examines key antecedents and consequences of board-level IT governance (ITG) using a multi-method approach. Structural Equation Modelling analysis applied to organization-level data collected from 171 board members suggested that the level of ITG exercised by boards was contingent upon the organization's ‘IT use mode’, along the two dimensions of need for (a) fast and reliable IT, and (b) new innovative IT. But, the findings further suggested that the contingency approach may be suboptimal because it can cause new ways of leveraging IT to be ignored. High levels of board-level ITG, regardless of existing IT needs, increased organizational performance. This phenomenon was illuminated with applicability checks. Moreover, content analysis and structured interviews with board members further enriched these insights. 相似文献

The influence of governance equilibrium on ERP project success 总被引:2,自引:0,他引:2
As the ERP adopter and ERP consultancy combine their efforts and resources to achieve mutually desirable goals, the problem of governance, which has been mainly identified as an intrafirm problem, is recognized to be an interfirm problem. To investigate the relationship between various governance mechanisms and their capacity to relieve project hazards, we propose a covariance model of ERP governance. The constructed model analyzes the complementary contributions of different governance mechanisms on ERP project success. Four governance mechanisms are studied, including explicit contracts, implicit contracts, reputation, and trust. This study holds that the virtue of one mechanism will grow into the gap of another, forming an equilibrium of governance structure. Then, the governance equilibrium plays a mediating role between ERP project hazards and ERP project success. Empirical analysis based on 122 ERP implementation projects shows a significantly positive relationship between governance equilibrium and ERP project success. Further, in support of transaction cost theory (TCT), the results indicate that governance equilibrium tends to be aligned with exchange hazards, specifically those associated with specialized investments and uncertainty. The empirical evidence suggests that governance equilibrium, when treated as a multidimensional construct, can provide a holistic representation of complex interfirm governance and allow researchers to match broad predictors with broad outcomes, leading to greater explanatory power of governance mechanisms on ERP project success. Implications, limitations, and future research directions of the study are discussed. 相似文献

IS researchers have normally assumed that satisfaction is the key factor influencing IS customers’ reuse of services; however, a focus on customer satisfaction does not always guarantee customer retention. We synthesized customer satisfaction and dissatisfaction models from prior service quality research to provide a comprehensive model predicting the behavioral intentions of customers to reuse IS services. Five research hypotheses were empirically tested by using a field study of 263 users of an IS service department. Our findings placed IS service quality in a causal network leading to IS service reuse and highlighted the relative importance that service quality value played in predicting behavioral intention to reuse the service. 相似文献

Although many IT service management frameworks exist, we still have limited theoretical understanding of IT service quality within a broader nomological network. Building on recent conceptual work on the IT service climate construct, this study empirically establishes it as a predictor of IT service quality using survey data from both IT units and their clients. Also examined was a set of antecedents which provide a foundation upon which a favorable service climate can be built. The IT service climate instrument, when incorporated into employee feedback initiatives, can provide guidance to IT executives about practices to improve service quality. 相似文献

Results from a survey of senior executives/officers in charge of IT suggest that while greater IT governance triggers more innovation, IT-business alignment does not moderate this relationship. Executive management IT competence has a direct and positive impact on innovation, and this relationship is stronger when moderated by IT-business alignment. However, regardless of IT-business alignment, innovation is not significantly affected by the board’s IT competence but is positively impacted by IT intensity. This study extends the IS literature on the role of IT in innovation and contributes to the IT governance literature. 相似文献

This study develops a conceptual model of organizational IT assimilation maturity based on constructs in the IS literature, qualitative data analysis of three exploratory case studies, and general morphological analysis (GMA). We inductively extract four dimensions of IT assimilation – business processes, information architecture, IT processes, and end-users – and characterize different maturity levels for each dimension. Applying Zwicky's GMA on the combinatorially large space of IT assimilation configurations, we prune the space to a more limited number of internally consistent and empirically feasible IT assimilation maturity profiles. We discuss how the model can support IT audit and governance activities. 相似文献

Over the years, Information Technology (IT) has struggled with how to create an effective structure and processes. It is our main thesis that if organizations focused more on implementing a sound IT governance strategy, it might help senior executives to manage not only the IT-related activities, but also the perceptions between IT and the rest of the organization, and, in doing so, foster a more successful IT organization. Using six case studies conducted within the oil and gas industry, we explore differences in perceptions toward IT and in the organization of IT activities. Using an Extended Platform Logic Perspective, we note differences and similarities between the firms, with respect to IT capabilities, relational and integration mechanisms, measures of success, and relationships with the business units. Our results suggest that our colleagues-in-practice have evolved from focusing on one-way architectures within a centralization/decentralization context toward a two-way relationship-oriented approach to managing the IT structure. We conclude by offering some thoughts on how IT executives can help to shape perceptions of IT within their firms and explore how academics can begin to help our colleagues-in-practice as they struggle with the governance of the IT function. 相似文献
