浅谈信息化对于烘焙企业的应用价值

《哈佛商业评论》说,IT不是竞争力。意思不是说IT不重要,而是说,一旦大家都认识到IT的价值,企业就不会因使用IT技术而更具竞争力。就像电一样,因为大家都在使用,它就不再是一种优势,但离开它却又举步维艰。对于国内烘焙企业来说,正是普及用"电"的时刻,谁都不想输在起跑线上,就需要及时认识到IT的价值——信息化对于企业的应用价值。

A practical framework for discussing IT infrastructure

Although increasingly important, IT infrastructure remains poorly defined. IT professionals need a practical framework to systematically discuss the nature, scope, evolution, and management of IT infrastructure. The guidelines presented can help one to think more clearly about infrastructure issues.     

How to future-proof your IT infrastructure

Today's tight budgets and the increasing complexity of IT infrastructures place incredible stress on the IT environment. IT managers are working hard to keep up with new technologies while supporting existing infrastructure. As the demands on a business infrastructure grow and expand to new areas, an IT infrastructure must support these new and varied needs. Taking a hard look at ones systems can uncover hidden opportunities for savings and provide funds to help one prepares for future demands.     

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.     

Valuing information technology infrastructures: a growth options approach

Decisions to invest in information technology (IT) infrastructure are often made based on an assessment of its immediate value to the organization. However, an important source of value comes from the fact that such technologies have the potential to be leveraged in the development of future applications. From a real options perspective, IT infrastructure investments create growth options that can be exercised if and when an organization decides to develop systems to provide new or enhanced IT capabilities. We present an analytical model based on real options that shows the process by which this potential is converted into business value, and discuss middleware as an example technology in this context. We derive managerial implications for the evaluation of IT infrastructure investments, and the main findings are: (1) the flexibility provided by IT infrastructure investment is more valuable when uncertainty is higher; (2) the cost advantage that IT infrastructure investment brings about is amplified by demand volatility for IT-supported products and services; (3) in duopoly competition, the value of IT infrastructure flexibility increases with the level of product or service substitutability; and (4) when demand volatility is high, inter-firm competition has a lower impact on the value of IT infrastructure.     

Cost accounting for shared IT infrastructures

IT infrastructure, such as servers and networking equipment, accounts for a large proportion of the IT costs in modern organizations. Typically, this IT infrastructure is shared among multiple applications and customers. Cost allocation of shared IT infrastructure is difficult and regularly based on biased cost allocation keys, which often causes free-rider problems. Measuring usage is technically difficult and incurs high costs. In this paper we propose a method to derive adequate estimators for the resource consumption of a customer-oriented service. These so-called resource profiles can then provide a basis for cost allocation keys. The estimators are derived from a series of load tests, as they are typically done before an application is launched in larger organizations. Such profiles need to be unbiased and precise even in cases of varying workloads and in rather heterogeneous environments. We describe the results of a set of experiments in an infrastructure provided by the BMW Group, and illustrate how the estimation can be integrated into existing IT service management processes. In our experiments we use Queuing Networks to validate the estimated resource profiles under different workloads.

IT-enabled knowledge ambidexterity and innovation performance in small U.S. firms: The moderator role of social media capability

This study examines the impact of information technology (IT)-enabled knowledge ambidexterity on innovation performance, and the potential moderator role of social media capability on a sample composed of 100 small U.S. firms. The empirical analysis suggests that IT infrastructure enables the firm to explore new knowledge and exploit existing/new knowledge to innovate more and better. We also find that social media capability has a positive moderator role in this equation: IT infrastructure and social media capabilities work together to enable knowledge ambidexterity.
