Human‐knowledge resources and interorganisational systems

This paper analyses how human‐knowledge resources affect interorganisational systems (IOS) capabilities and subsequently attainment of operational and strategic benefits. A conceptual model is constructed combining the transaction cost economics (TCE) view, resource‐based view (RBV) and insights from IOS literature. The model is tested through a triangulation approach combining two qualitative case studies and a quantitative field study within the logistics sector. This sector is chosen due to its need for high reliance on information technology. The findings indicate that human knowledge positively influences IOS capabilities related to cross‐organisational business processes and transfer of knowledge. Findings also show that strategic benefits are the consequence of knowledge transfer, when the transfer supports business processes resulting in operational benefits. The main theoretical contribution of this paper is that it combines a TCE view and RBV to analyse the effect of relationship‐specificity of human‐based knowledge resources in IOS.     

A cohesion measure for object‐oriented classes

In object‐oriented systems, cohesion refers to the degree of the relatedness of the members in a class and strong cohesion has been recognized as a highly desirable property of classes. We note that the existing cohesion measures do not take into account some characteristics of classes, and thus often fail to properly reflect the cohesiveness of classes. To cope with such a problem, we propose a new cohesion measure where the characteristics of classes are incorporated. Our cohesion measure takes into account the members that actually have impact on the cohesiveness of a class, and is defined in terms of the degree of the connectivity among those members. We develop a cohesion measurement tool for C++ programs, and perform a case study on a well‐known class library in order to demonstrate the effectiveness of our new measure. By performing principal component analysis, we also demonstrate that our measure captures a new aspect of class properties which is not captured by the existing cohesion measures.

Drivers and export performance impacts of IT capability in ‘born‐global’ firms: a cross‐national study

Past research focusing on large firms has argued that information technology (IT) capability enhances firm performance. However, these studies have seldom explored why firms develop IT capability, and have also left a void the understanding of the role of IT capability in Small‐ and medium‐sized enterprises (SMEs). This study attempts to fill that void by examining the effect of relevant environmental and firm‐level factors on IT capability, and the effect of IT capability on the export performance of Chinese and US born‐global firms, a special breed of export‐focused SMEs. Results indicate that environmental factors such as information intensity, and firm‐level factors such as international entrepreneurial orientation, prompt born‐global firms to develop IT capability. Further, our results also strongly emphasise the positive role that IT capability plays on the performance of born‐global firms. Finally, a comparative analysis of the Chinese and US born‐global firms revealed a lack of a cross‐cultural difference in the factors leading these firms to develop IT capability, therefore supporting the ‘convergence’ perspective in cross‐cultural research.     

Realising platform operational agility through information technology–enabled capabilities: A resource‐interdependence perspective

Intensifying competition in recent times requires business‐to‐consumer (B2C) e‐commerce platforms to develop operational agility for competitive advantage. Despite the agreement on an increasing competitive landscape, the process for realising information technology (IT)‐driven operational agility on e‐business platforms has received little scrutiny. Through an investigation of M.com, a leading multisided online retailing platform in China, this study provides a clear thesis of resource interdependencies and IT‐enabled capabilities forged during operational processes to realise operational agility. Our investigation, observations, and reflections from practice substantiate a model of how a platform like M.com cultivates IT‐driven resource‐interdependent competencies and capabilities tantamount to realising operational agility. The model shows how IT enables three capabilities—localised, synergistic, and optimised—which reflect the effective co‐ordination of three resource interdependencies (pooled, sequential, and reciprocal) during M.com's complex operations and processes, and explicates the consequences. For research, we postulate that IT‐enabled operational agility in complex organisational forms, cultivated through the development of resource‐interdependent capabilities to deliver effective sensing and response mechanisms, forms effective strategies for the B2C platform in dynamic marketplace conditions.     

A set‐oriented method definition language for object databases and its semantics

In this paper we propose a set‐oriented rule‐based method definition language for object‐oriented databases. Most existing object‐oriented database systems exploit a general‐purpose imperative object‐oriented programming language as the method definition language. Because methods are written in a general‐purpose imperative language, it is difficult to analyze their properties and to optimize them. Optimization is important when dealing with a large amount of objects as in databases. We therefore believe that the use of an ad hoc, set‐oriented language can offer some advantages, at least at the specification level. In particular, such a language can offer an appropriate framework to reason about method properties. In this paper, besides defining a set‐oriented rule‐based language for method definition, we formally define its semantics, addressing the problems of inconsistency and non‐determinism in set‐oriented updates. Moreover, we characterize some relevant properties of methods, such as conflicts among method specifications in sibling classes and behavioral refinement in subclasses.

Inside the adaptive enterprise: an information technology capabilities perspective on business process agility

Recent innovations in utility computing, web services, and service-oriented architectures, combined with a growing array of IT skills, have improved firms’ ability to be more agile in responding to change. Using the resource-based view of the firm, prior research suggests that IT resources, in isolation, are unlikely to yield superior performance and so as firms try to boost their agility, the question becomes how to configure IT resources to prepare for, or react to, change. In this paper, we posit that managerial IT capabilities based on IT-business partnerships, strategic planning, and ex-post IT project analysis lead to the development of technical IT capabilities associated with a flexible IT infrastructure which in turn drives agility or a firm’s ability to react to change in its products and markets. Using data from matched surveys of IT and business executives in 241 firms, we find that managerial and technical capabilities affect agility. In further testing, we reveal that in a stable setting, technical IT capabilities are more important to agility than managerial IT capabilities, while in a dynamic setting, the opposite is true. Thus, for firms operating in volatile markets, effective models of managerial IT governance are essential for delivering superior agility or adaptiveness.

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.

A taxonomy of market‐based resource management systems for utility‐driven cluster computing

In utility‐driven cluster computing, cluster Resource Management Systems (RMSs) need to know the specific needs of different users in order to allocate resources according to their needs. This in turn is vital to achieve service‐oriented Grid computing that harnesses resources distributed worldwide based on users' objectives. Recently, numerous market‐based RMSs have been proposed to make use of real‐world market concepts and behavior to assign resources to users for various computing platforms. The aim of this paper is to develop a taxonomy that characterizes and classifies how market‐based RMSs can support utility‐driven cluster computing in practice. The taxonomy is then mapped to existing market‐based RMSs designed for both cluster and other computing platforms to survey current research developments and identify outstanding issues.

Commodity or competitive advantage? Analysis of the ERP value paradox

A true e-business enabled firm needs the support from a well-tuned enterprise resource planning (ERP) system for providing real time data. However, many companies complain that after their huge investments in ERP systems, they found the ERP systems do not bring them new orders, new profits, or competitive advantage as ERP vendors claim. Academic studies also found mixed results regarding ERP’s payoff. In line with resource based view (RBV), the study proposes an integrated model to shed light on the ERP value paradox. We try to answer “With what organizational resources and by building what firm specific capabilities, the investment in ERP systems may bring firms competitive advantage”. Using a sample of 150 ERP and e-business adopters in the US, we found that (1) organizational resources such as managerial skills and organizational change management play a more important role than IT resources (ERP, e-Business technologies) in generating business integration capability. (2) However, neither IT resources nor organizational resources directly provide firms with competitive advantage. Instead, business integration capability built from the two resources plays a mediating role through which business achieves competitive advantage.     

The role of information governance in big data analytics driven innovation

The age of big data analytics is now here, with companies increasingly investing in big data initiatives to foster innovation and outperform competition. Nevertheless, while researchers and practitioners started to examine the shifts that these technologies entail and their overall business value, it is still unclear whether and under what conditions they drive innovation. To address this gap, this study draws on the resource-based view (RBV) of the firm and information governance theory to explore the interplay between a firm’s big data analytics capabilities (BDACs) and their information governance practices in shaping innovation capabilities. We argue that a firm’s BDAC helps enhance two distinct types of innovative capabilities, incremental and radical capabilities, and that information governance positively moderates this relationship. To examine our research model, we analyzed survey data collected from 175 IT and business managers. Results from partial least squares structural equation modelling analysis reveal that BDACs have a positive and significant effect on both incremental and radical innovative capabilities. Our analysis also highlights the important role of information governance, as it positively moderates the relationship between BDAC’s and a firm’s radical innovative capability, while there is a nonsignificant moderating effect for incremental innovation capabilities. Finally, we examine the effect of environmental uncertainty conditions in our model and find that information governance and BDACs have amplified effects under conditions of high environmental dynamism.     

In search of Europe's information technology leaders: review of methods and empirical evidence

Abstract. Information technology (IT) leaders — companies that successfully exploit IT to achieve business results — generate immense interest among practitioners and academics. From a practitioner's perspective, IT leaders provide benchmarks of leading IT management practices which others may emulate to achieve success. From an academic perspective, IT leaders provide the 'data' for the creation of frameworks and theories of IT management. While US IT leaders are regularly assessed by academics, trade magazines, consultants and benchmarking firms, there has been no Europe-wide assessment of IT leadership. This neglect is detrimental to European IT practitioners and academics who may discover that American IT management practices are not transferrable in the European context. In this article, we analyse the construct, context and statistical validity of six methods for identifying European IT leaders. Based on this analysis, two methods (expert ratings and citation counts) were used to generate a preliminary list of European IT leaders and laggards. While individual experts were reticent about volunteering their ratings, their collective view appears to generate a worthwhile list with high construct validity. Citation counts represent a more accessible process for list generation, with high statistical validity. However, an attempt to correlate expert ratings with a list based on citation counts confirms that the latter has questionable construct validity.     

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.     

Flexible and efficient profiling with aspect‐oriented programming

Many profilers for virtual execution environments, such as the Java virtual machine (JVM), are implemented with low‐level bytecode instrumentation techniques, which is tedious, error‐prone, and complicates maintenance and extension of the tools. In order to reduce the development time and cost, we promote building profilers for the JVM using high‐level aspect‐oriented programming (AOP). We show that the use of aspects yields concise profilers that are easy to develop, extend, and maintain, because low‐level instrumentation details are hidden from the tool developer. In order to build efficient profilers, we introduce inter‐advice communication, an extension to common AOP languages that enables efficient data passing between advices that are woven into the same method using local variables. We illustrate our approach with two case studies. First, we show that an existing, instrumentation‐based tool for listener latency profiling can be easily recast as an aspect. Second, we present an aspect for comprehensive calling context profiling. In order to reduce profiling overhead, our aspect parallelizes application execution and profile creation, resulting in a speedup of 110% on a machine with more than two cores, compared with a primitive, non‐parallel approach.

Aspect‐oriented component assembly—a case study in parallel software design

In this paper we deal with building parallel programs based on sequential application code and generic components providing specific functionality for parallelization, like load balancing or fault tolerance. We describe an architectural approach employing aspect‐oriented programming to assemble arbitrary object‐oriented components. Several non‐trivial crosscutting concerns arising from parallelization are addressed in the light of different applications, which are representative of the most common types of parallelism. In particular, we demonstrate how aspect‐oriented techniques allow us to leave all existing code untouched. We evaluate and compare our approach with its counterparts in conventional object‐oriented programming. Copyright © 2008 John Wiley & Sons, Ltd.     

Developing an object‐oriented framework for content‐based image retrieval

Content‐based image retrieval (CBIR) is a process of retrieving images from an image database by exploiting the content of the images (typically the querying of an image). CBIR avoids many problems associated with traditional ways of retrieving images by keywords. Thus, a growing interest in the area of CBIR has been established in recent years. In this paper, a novel object‐oriented framework (CBIRFrame) is built for CBIR applications development. We discuss the motivations for CBIRFrame before discussing its design in detail. Two applications of CBIRFrame are also briefly discussed to show the effectiveness of applying CBIRFrame to real applications. Finally, we outline the possible uses of the design of CBIRFrame for other types of domains, such as content‐based retrieval of video clips. Copyright © 2003 John Wiley & Sons, Ltd.     

Assessing the importance of industry in the adoption and assimilation of IT: Evidence from Italian enterprises

We analysed the role of industry in determining the diffusion and business value created by IT. Data was collected for this purpose by surveying 192 large enterprises in Italy. Our research revealed three findings. First, in the material services and non-hi-tech manufacturing industries, firms had a relatively limited adoption of IT, resulting in little business impact. Second, firms’ IT spending behaviour depended on their industry type and not on their IT capabilities. However their capabilities were more important than industry in explaining why firms achieved benefits from IT adoption that depended on the previous accumulation of IT resources and other capabilities. Third, industry type determined the degree to which IT affected profitability and its effectiveness in helping firms to defend their competitive advantage. Specifically, the slower the adoption of IT in an industry, the greater its impact on the firm's profitability.The implications of these findings for managers and policy-makers are discussed.     

Investigating IT Governance through the Viable System Model

This paper investigates IT governance through the Viable System Model (VSM). We make a theoretical contribution by discussing why IT governance can continue to achieve its purpose of creating and preserving IT business value. Additionally, we demonstrate how the VSM can be used as a lens to describe and diagnose IT governance from a practical perspective, offering insights in how complexity can be unfolded and how complexity engineering takes place to handle changing complexity.
