In this paper, derived some function factors from ITA role in organization as to analyze what ITA function has influenced on ITA governance. The factors of IT governance system and their effects on the enterprises organizations are discussed and the relationships are verified by empirical mode method. In result of statistical analysis based on the 320 case of organizations toward public and private enterprises in South Korea, it appeared that IT infrastructure, IT technology system and IT performance system of IT functions are the contributing factors on the IT governance.

Service and service systems concepts are fundamental constructs for the development of the emergent SSME, ITSM, and Service Oriented Software (SOS) knowledge streams. A diversified literature has provided a richness of findings, but at the same time, the lack of standardized conceptualizations is a source of confusion to IT practitioners and academics. Given this problematic situation, we pose that a systems approach is useful to address it. In this article, we review and synthesize key studies in these knowledge streams to design: (ⅰ) a framework to characterize both concepts under a system view and, (ⅱ) harmonized definitions (e.g. identification of shared and essential properties) for such fundamental concepts. Our main contribution is scholastic, but we are confident that the posed conceptual artifacts can be further used to elaborate standardized definition for the IT service and IT service system constructs, as well as analysis tools for describe real service systems.

展开AbstractMonitoring and repair are two sides of the on-the-fly maintenance of IT systems. Monitoring is well supported by automatic tools. In contrast, repairs involve much higher human intervention which negatively affects reliability and efficiency. The paper introduces a method of automating repairs of IT systems which can be integrated with any of the existing monitoring mechanisms. The method is described as a collection of models and algorithms. The monitored system is modelled as a multi-hierarchy of components, and predicates are used to detect problems and to trigger the corresponding repairs. Repair procedures are represented using flow diagrams. Graphical notations are used to specify the architecture of the runnable component of the proposed method and the corresponding repair API. Formal notation (theZlanguage) is used to provide for precision and unambiguity of the specifications. The formal specification facilitates reuse of the method in different target environments. For validation purposes, the method has been instantiated (using the PERL language) in an industrial helpdesk supporting the operation of several hundred IT systems. The validation data demonstrate the significant positive impact of the proposed method on the efficiency of the performed repairs.收起

The introduction of new technology presents a unique set of challenges which are unlike from any other change process. It brings itself changes which directly impacts user's performance and their day to day activities. Due to its profound impact on the user, they tend to have certain anticipations and concerns from the new technology which influence the acceptance of new technology. Adopting key informants interview methodology, user anticipations and concerns arising from the new technology are identified. The findings suggest that generally users' expectations and concerns are drawn from their previous experience with the IT system and they tend to view a new implementation as what is in there for them. The paper concludes by providing a framework overcoming the resistance to the new system by incorporating key factors relating to the user anticipation and concern, and suggesting strategies to improve successful adoption and to increase user involvement.

The role of IT in achieving the organisation's strategic development goals has been an area of constant debate. This paper describes the experiences of John Nicholls Builders Ltd, a Cornish building firm, in their attempt to achieve their strategic development goals through the adoption of IT. The implementation stage of the project involved setting a flexible programme and timescale from the start. The company adopted a bottom up approach whereby potential users were consulted and involved in the process. Also the support of top management staff was crucial for the successful transition to the new system. Although there was no single ready-made solution that could fit the organisations requirements, they were able to identify appropriate construction industry software packages and integrate them through development of an intranet and database system. Now, there is greater management control, all departments have greater access to information, enabling them to function more effectively and efficiently, and since projections are more accurate or now available, management can make long-term strategic plans. These improvements and developments to the business system have improved operational efficiency, turnover and profitability of the organisation.

Many organizations have adopted chargeback systems whereby users are charged for the IT resources which they use. The purpose is to control the costs of information technology. Chargeback systems have recently received a resurgence of interest with the rapid change in IT. Many writers are currently advocating chargeback systems to control the escalating costs. Chargeback systems are expected to increase user awareness of IT costs, and thereby, improve decisionmaking and effectiveness of Information Technology. Many organizations have never adopted chargeback systems. They have used other management techniques for controlling IT costs. Chargeback systems have been controversial since the earliest computer applications. The current environment has added new issues which have provoked discussion. This article discusses the advantages and disadvantages of chargeback systems. The emphasis is on new issues which have arisen due to the changing technological environment. The dimensions which frame the discussion are the evolving empowerment of users, complexity of systems, and the cost structure. Recommendations are made for effectively using chargeback systems alternatives. [References: 93]

The current study is designed to be used as supplementary material for potential professionals in the area of IT process alignment. This study deals with automation of trouble ticketing system. With this new technology, the company needs to properly align their IT processes with investment model and automation. The proper alignment will bring about dramatic improvements in their business performance. This case study walks through the major components in estimating the financial impact of IT process alignment.
