信息系统战略指标体系研究

企业在引入企业信息系统时,企业信息系统战略和企业总体战略取得一致是非常重要的。本文阐述了战略对应模型的几个关键领域和对应过程,提出了企业战略与信息系统战略对应评价的指标体系,并分析了各指标的涵义和评分方法。     

基于战略对应的IT项目组合选择模型

把信息技术项目当作组合来管理可以通过平衡风险和收益来促进企业目标和IT应用的结合,但由于决策信息的不确定性和IT项目目标与企业战略的难以对应,企业面临IT项目组合选择的挑战。构建基于战略对应的IT项目组合选择模型,其中模糊集和模糊层次分析法用来刻画不确定信息和评估IT项目风险、成本及收益,关键成功因素法用来提高IT项目与企业战略的对应,并建立模糊0－1整数规划。利用定性可能性理论把模糊组合选择模型转化为一般可求解的整数规划形式,最后用一个案例说明模型的用法。     

基于战略匹配和IT能力的企业IT项目决策

为将战略匹配思想和IT能力对1T项目的影响转化为量化模型,支持企业更科学地进行IT决策,引入网络层次分析法模拟企业战略与IT战略之间双向对应和协同关系,分别借助Porter的战略理论和Henderson的战略匹配模型来代表企业战略和IT战略。考虑各种IT能力对IT战略和IT项目的影响,提出基于战略匹配和IT能力的IT项目决策模型,并以实例说明该模型的使用方法和有效性。     

面向不同利益相关者的IT投资决策模型

为了响应不同利益相关者在IT投资决策过程中的不同需求,把备选项目看作一个组合,综合IT项目的战略对应和财务收益为目标,权衡其成本、收益和风险,构建基于模糊多目标规划的IT投资决策模型,其中模糊数用来刻画不确定的项目信息。通过改变各临界值和求解过程中产生的参数,模型支持各种假设分析。最后用案例说明模型的用法和功能。     

基于平衡计分卡的IT治理模型研究

企业在实施IT治理过程中,对于项目的评价、开发、实施以及维护,需要一种多指标的方法来进行目标分解。平衡记分卡可以帮助企业来分解目标,同时根据对于目标的绩效考察来驱动战略。首先介绍IT治理的概念、模型以及IT平衡记分卡的四个维度,接着提出了一个Cobit与IT平衡计分卡相结合的瀑布模型,解决了IT治理中的绩效评价问题,使得IT治理过程更加完善和成熟。     

基于改进的NSGA2算法考虑病患公平性及医院运作成本的病床配置优化研究

针对目前医院病床调度存在运营成本较大以及医患关系之间公平性的问题,提出一个考虑医院运作成本和病患公平性下单科室病床分配的多目标随机规划模型。首先,根据基于医院的相关政策,提出一个考虑响应性与准入性的权重测度指标来反映医患关系的公平性,并考虑医院的运作成本建立多目标随机规划模型;其次,为方便算法求解,引入线性化方法将复杂模型处理成混合整数线性模型;最后,采用改进后的NSGA2算法对多目标问题求解,并对算例进行不同的数值实验。通过调整不同的参数进行相对应的灵敏度分析,改进后的算法提升了算法的收敛性与多样性,实验结果验证了模型的有效性和适用性。     

考虑用户选择偏好的电动汽车充电站规划研究

在国家大力发展新能源汽车的过程中,充电问题一直阻碍着电动汽车的发展,充电基础设施尤其是快速充电站的规划和建设尤为重要。大规模发展电动汽车（electric vehicle,EV）的关键是根据用户的充电选择偏好,建立完善的充电基础设施,减少用户的里程焦虑,彻底解决充电不方便的问题。在考虑了各方面社会因素并确定一定数量的候选节点背景研究的基础上,提出了一种双目标规划模型,在满足需求、距离、容量等约束条件下,分析了建设充电站总成本和充电覆盖范围之间的关系,寻找最优的充电站建设方案,并以A城市B区为例,通过多目标粒子群算法进行求解,求出充电站的最佳节点和数量。用不同算法进行求解,通过对结果进行分析比较,表明多目标粒子群算法（MOPSO）在求解双目标问题时更具有实际意义。     

指标量化IT服务管理

为IT服务建立优质的指标,可以实现业务与IT更好的协调,并帮助企业达成目标。为了使业务目标与IT之间协调一致、帮助业务运营达标,并为实现卓越的IT运营提供战略推动力,在IT服务管理中需要运用一些指标。     

IT服务管理的“章法”

IT服务管理(ITSM)是一个新兴的知识领域。它出现的背景是20世纪80年代英国政府商务办公室(OGC)为解决“IT投资、采购与IT服务质量不佳”问题,而提出的一整套方法论体系。这套方法论体系叫做ITIL(信息技术基础设施库)。 经过近20年的发展,以ITIL为核心形成的ITSM知识与方法体系,日渐成为解决IT与企业战略、IT与服务品质、IT与客户需求、IT与系统维护和管理之间相匹配的一系列成熟的流程。这些流程,是通过大量的企业应用实践,证明是行之有效的。     

项目组合管理在IT治理中的作用

IT治理要决定IT制定什么决策的问题,在决策制定过程中,决定选择哪些项目投资,每个项目投入多少资金是IT组织对企业战略的理解,对IT基础架构的规划,对IT服务决策的直接反映等。企业通过实施新的项目来实现业务战略,达到业务目标。但是资金和开发人员是有限的,技术管理部门往往缺     

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.     

The leveraging influence of strategic alignment on IT investment: An empirical examination

Businesses have invested enormous sums in information technology (IT). The challenge now is to optimize these investments. We empirically examined the influence of the alignment between IS strategy and business strategy (strategic alignment) on the payoff of IT investment. Many studies have been performed on the value of IT investment and strategic alignment separately, in the past, but here we combined them by investigating the moderating affect of strategic alignment on the relationship between IT investment and firm performance for a group of manufacturing firms. The results indicated that there is a synergistic coupling between strategic alignment and IT investment with firm performance. Firms that have aligned IT and business strategies can invest in additional IT resources with some assurance that they will be leveraged substantially. One of our main contributions was in the examination of four differing perspectives of strategic alignment and their relationship with the payoff of IT investment.     

CEO/CIO mutual understanding,strategic alignment,and the contribution of IS to the organization

Mutual understanding between the CEO and CIO is thought to facilitate the alignment of an organization's IS with its business strategy, and thereby enhance the contribution of the IS to business performance. A survey of 202 pairs of CEOs and CIOs was taken to investigate the relationships between them. Mutual understanding was measured as the role of IS in the organization, using the perspectives of both executives. Strategic alignment was measured as the fit between the CEO's assessment of eight STROBE dimensions and the CIO's assessment of the analogous STROEPIS dimensions; both the CEO and CIO evaluated IS contribution. Mutual understanding of the role of IT led to seven alignment dimensions whereas six alignment dimensions led to IS contributions. Our study extended the theory of IT strategic alignment and provided direction for CEOs and CIOs interested in improving the IS contribution of their organization.     

Effects of strategic alignment on IS success: the mediation role of IS investment in Korea

The purpose of this research is to develop a comprehensive information system (IS) evaluation model for IS success linked to organizational performance. The primary focus of this research is to investigate the role of IT investment in business values by means of a group survey of about 300 business executives in Korea. We used the contingency theory to discover the mediation effect of IS investment on strategic alignment and IS success. In contrast to previous research, this study expanded the test scope to IS architecture and organizational structure at the operational level. The results from 273 business executives in Korea indicated that strategy integration with IT is positively related to IT investment, and IT investment is a critical antecedent of IS success. Thus, the implications of the findings are that right-directional IT investment has played an important role in the success of IT companies in Korea.     

Aligning the IT portfolio with business strategy: Evidence for complementarity of corporate and business unit alignment

Research on alignment between business strategy and information technology (IT) strategy has generated extensive insights over the last three decades. That research has focused primarily on the fit between business and IT strategies, while cross-domain alignment, i.e., alignment between business strategy and IT infrastructure components, has received far less attention. Further, previous studies have focused on the implications of alignment for firm performance while the effects of cross-domain alignment on business unit performance in multi-business organizations (MBOs) are yet to be examined. This issue is important as IT infrastructures are evolving rapidly. Specifically, MBOs are increasingly turning to corporate IT platforms to support a common set of shared IT needs, while still allowing individual business units to manage unique aspects of their own IT needs through local IT applications. Extending prior research, this study proposes that performance of business units in MBOs is influenced by two complementary forms of cross-domain alignment, viz., alignment between the corporate IT platform and the corporate business strategy, and alignment between the business unit’s portfolio of IT applications and its business strategy. Using data from a global survey of 120 organizations, we find evidence that complementarity between these two forms of cross-domain alignment creates a joint positive effect on business unit performance. We also find that this effect varies with the extent of process digitization within business units. Implications for theory and practice are discussed.     

Opportunistic strategy formulation for IS/IT planning

Existing models and frameworks for information systems and information technology (IS/IT) planning are not robust enough to explain or predict strategic gains and many organizations are wary of investing further in their information infrastructure. Because technology is not the only ingredient of success, a complete and rigorous reconsideration of the techniques, options and approaches to IS/IT planning linked to business strategy is needed. It is argued that this can only be achieved through consideration of the recent organizational processes involved for creating a successful IS/IT strategy. This paper reviews aspects of both the literature on business strategy and IS/IT planning and considers case examples from two organizations in which the contrasting outcomes from the same technical innovation illustrate the dynamics of opportunistic strategy formulation.     

Rapid business and IT change: drivers for strategic information systems planning?

Today's organizations increasingly plan new information systems (IS) to better compete. Through such planning, they attempt to align their IS strategy and their business strategy. This study tested the impact of business and information technology (IT) change on strategic information systems planning (SISP) horizon, of horizon on the planning itself, and of the planning on the alignment of IS strategy and business strategy. A questionnaire defined business change, IT change, and alignment as multi-item scaled questions, and planning horizon as a single, nonscaled one. It defined a multi-item scaled SISP measure as both a second-order construct and as single-order constructs for its individual phases. A postal survey collected data from 161 IS executives. Constructs were extensively validated. The analysis used structural equation modeling, and surprisingly found that business change predicted longer SISP horizons, but IT change predicted neither longer nor shorter ones. Planning horizon predicted SISP itself (as a second-order construct and as all of its phases), and such planning (as a second-order construct, and as strategic awareness and strategy conception phases) predicted alignment of IS strategy and business strategy. These findings suggest that practitioners more carefully assess their own degree of caution in setting planning horizons in response to business and IT change. In fact, the findings suggest it may not be necessary for practitioners to shorten planning horizons in a rapidly changing environment.     

Information management in the global enterprise: an organising framework

Much has been written over the last decade on managing global enterprises. While the predominant concern of this literature has been strategic in orientation, the management of information is a neglected area. By drawing on a diverse range of literature in the international business, strategic management, organization design, and information system (IS) disciplines this paper develops a conceptual framework for analysing information management in the global enterprise, providing a basis for organising existing literature on the topic and for creating a map of the field. This framework is structured around four domains: global business drivers, global business strategy, global business model and global information strategy. It highlights the role of information technology (IT) as supporting global business strategies while at the same time IT can also be a major catalyst in the globalisation process itself. In the context of the global information strategy, the paper develops a distinction between business infostructure, IT infrastructure and the IS/IT suprastructure. Significant relationships between the four domains of the framework are surfaced and an agenda for action developed.     

Business–IT alignment maturity of companies in China

Business–IT alignment has been consistently ranked as the number one concern of IT and business executives. Maintaining the alignment has been found to lead to stronger business performance, higher perceived value of IT and improved IS strategic planning; therefore addressing the issue is both important and timely. The economic growth in China in the last decade has led to greater availability of IT and its widespread use as a critical resource. Despite the increasing interest in Chinese IS issues by both researchers and practitioners, empirical research focusing on human- and organization-related IS issues in China is scarce. Using data collected from 130 business and IT executives from 22 companies in China, 11 of which were multinationals operating in China, we explored several questions in the area of business–IT alignment. An instrument designed to measure the six dimensions of business–IT alignment maturity was cross-validated using a sample of companies in China. Then, the instrument was refined to develop a measurement method that offered better reliability and validity in the context of Chinese companies. The relationship between the alignment maturity dimensions and IS strategic alignment was then examined. Finally, the alignment maturity of companies in China was assessed to provide a snapshot of business–IT alignment in China. A comparison between the 11 Chinese domestic companies and 11 multinational operating in China provided insight into the different IT practices of the two types of companies. Implications for researchers and practitioners are discussed.     

Alignment within the software development unit: Assessing structural and relational dimensions between developers and testers

Just as business-IT alignment has received significant focus as a strategic concern in the IS literature, it is also important to consider internal alignment between the diverse subunits within the IT organization. This study investigates alignment between developers and testers in software development to understand alignment within the IT unit. Prior evidence of tension between these sub-groups (and others as well) suggests that all is not necessarily well within the IT organization. Misalignment within the IT unit can certainly make it difficult for the IT unit to add strategic value to the organization. This study is an important initial step in investigating IT subunit alignment which can inform future research focusing on the alignment of other IT subunits such as architecture, operations, and customer-support. Using theoretical concepts from strategic business-IT alignment, we test a research model through a survey of professional software developers and testers. Results suggest that relational but not structural dimensions influence IT subunit alignment.
