IT professionals and organisational ascendancy: theory and empirical critique

IT expertise cannot be viewed as a decisive asset in organisational tournaments. Survey findings suggest IT competence is associated with severe handicaps in power contests between professional/managerial strata. At least for the present, there are strongly negative implications for hypotheses of organisational ascendancy for IT professionals or for their successful achievement of a collective mobility project.     

A framework of E-SCM multi-agent systems in the fashion industry

The fashion industry's supply chain is full of uncertainty and unpredictability. Thus, building an intelligent system to effectively capture the requirements of customers and help manage the supply chain is very important. Typical quick response (QR) systems have been broadly used in the fashion industry to serve as a way of maintaining an efficient supply chain management (SCM). The original functions of a QR system cannot, however, completely overcome the challenge of quickly satisfying the requirements of customers with effective customer relationship and quality of service. In this paper, we have integrated the typical management information system (MIS) development procedure with that of an e-fashion SCM multi-agent system. Some related research and reports from different countries have been thoroughly surveyed in order to find possible IT and non-IT methods for use in the SCM of fashion retailers. This paper thus provides an electronic fashion SCM system by adopting the techniques of the Semantic Web and multiple agents. The proposed system can integrate different information technologies to make its behavior more intelligent and to catch more useful information from customers. Its implementation also considers some practical issues in the fashion retailing SCM.     

Information Technology Tools in New Product Development: The Impact of Complementary Resources*,†

Emergent research has examined the antecedents to using information technology (IT) in the new product development (NPD) process and the impact of IT on NPD performance. Based on the resource‐based view (RBV) of the firm, this study hypothesizes that particular resources create IT capabilities that significantly enhance NPD outcomes. More specifically, this research extends previous work by investigating whether three complementary resources, namely an executive champion for IT, global engagement, and organizational innovativeness, influence IT capabilities (IT use frequency and IT replacement frequency), which in turn affect NPD outcomes (NPD task proficiency and NPD performance). To test the conceptual model, survey data were collected from 220 NPD and IT managers in a variety of large Japanese firms. The results show that an executive champion for IT and global engagement are predictors of both IT tool use and replacement frequency while organizational innovativeness contributes only to IT tool replacement frequency. The results also indicate that both IT tool use and replacement frequency have a positive effect on NPD task proficiency, which improves NPD performance. This research contributes to the literature by adding understanding of the role of IT in NPD at the firm level in four ways. First, it examines particular organizational complementary resources and their relationship to IT capabilities. Second, it examines the RBV and IT in the context of NPD, an important business process. Third, it measures IT usage in a more granular fashion (i.e., IT tool use frequency and IT replacement frequency) rather than simply IT usage as a dichotomy. Finally, through testing the proposed model with data collected from Japanese firms, this study provides empirical evidence from an Asian country to answer the call for more NPD research to be conducted in countries other than North American and Western European contexts. The findings of the study also provide implications for managers. Importantly, they indicate that an executive level champion for IT is a key influencer in facilitating IT usage and replacement, and likely can help generate awareness of and support for greater IT investments so the firm can create IT capabilities for effective NPD.     

Determinants of IT Usage and New Product Performance*

Explosive growth of information technologies (IT) has prompted interest in examining the role of IT in new product development (NPD). Through desktop software and Web‐based tools, IT has been used to aid idea generation and product testing as well as for NPD activities such as process and portfolio management. Recent research suggests, however, that a gap exists between IT availability and usage. Given the importance of IT in creating business value through the development of new products and services, the present study seeks to identify factors that affect IT usage. Further, anecdotal evidence and conceptual studies intimate that the usage of IT tools for NPD can shorten time to market, can improve product quality, and can increase productivity. However, empirical substantiation of this impact is mostly nonexistent. The current study investigates the relationship between IT usage and two measures of new product performance: speed to market and market performance. Employing a mail‐survey methodology, the study uses data from a sample of practitioner members from the Product Development & Management Association to examine the effect of project risk, existence of a champion, autonomy, innovative climate, IT infrastructure, and IT embeddedness on the extent of IT usage. These data are also used to explore the impact of IT usage on speed to market and market performance. The results indicate that project risk, existence of a champion, and IT embeddedness positively affect the extent of IT usage for NPD. Additionally, IT usage positively and significantly influences the performance of the new product in the marketplace. Surprisingly, and contrary to popular belief, IT usage does not have any impact on speed to market. An important implication of this study is that IT usage influences performance but not in the way managers expect. Specifically, IT usage does not seem to affect speed to market but rather positively impacts the performance of the new product in the marketplace. This result suggests that IT usage in NPD provides far more value to firms than previously thought and provides evidence to support greater investments in IT for product development efforts. Other implications of the study are that unless IT is embedded into the NPD process and champions for IT tools exist, chances are that IT will not be used and its benefits will not be realized.     

Antecedents and Consequences of Information Technology Usage in NPD: A Comparison of Dutch and U.S. Companies*

This study examines information technology (IT) usage for new product development (NPD) in a global context. Specifically, this research seeks to ascertain the factors that influence IT usage and the relationship between IT usage and new product performance in two different countries—the United States and the Netherlands. The interest here is in discovering if, and how, these relationships may be different depending on the country within which the NPD effort is undertaken. Employing a mail survey methodology, the present study uses data from a sample of U.S. practitioner members from the Product Development & Management Association (PDMA) and new product managers from Dutch manufacturing companies to examine the effect of IT infrastructure, IT embeddedness, NPD process formalization, colocation, outsourcing of NPD projects, and length of time on the job on the extent of IT usage. The data are also used to explore the impact of IT usage on speed to market and market performance. The results indicate that IT embeddedness and NPD process formalization positively influence IT usage in both the United States and the Netherlands. Colocation and length of time on the job are negatively associated with IT usage only in Dutch firms. Similarly, outsourcing of NPD projects is positively related to IT usage only in U.S. firms. Finally, IT usage has a positive relationship with speed to market in the Netherlands and with market performance in the United States. An important implication of the present study is that IT usage does impact speed to market and market performance, confirming anecdotal evidence. However, these relationships are not the same in each country. Moreover, the antecedents to IT usage also vary by country. Thus, the precursors and consequences of IT usage in NPD are context specific. Another implication of this research is that unless IT is embedded into the NPD process, it is unlikely that the benefits of IT will come to fruition. Finally, this study suggests that as firms use more globally dispersed teams for NPD and outsource more of their development activities, IT usage is likely to increase to facilitate communication and cooperation.     

The impacts of country characteristics upon the value of information technology as measured by productive efficiency

Based on the theory of production, this paper investigates information technology (IT) contribution at a country level by linking it to the complementarity/substitutability phenomena created by the joint presence of IT and the five selected national characteristics. It negates the relationship between IT value and productivity based on a comprehensive panel data set from 25 countries over the period 1997-2006, when the individual analytical method is applied and productive efficiency is used as the performance criterion. The IT productivity paradox is re-examined under the one-equation stochastic frontier production model, while the influence of the five national characteristics is tested under the two-equation stochastic frontier production model. The findings include the following: (i) The IT productivity paradox occurs in not only middle-income (developing) countries but also high-income (developed) countries. (ii) Eastern European countries gain more productive efficiency than the G7 countries when IT is considered as a production factor. (iii) Different national characteristics have impacts on a country's output and productive efficiency. (iv) The chosen national characteristics present both complementarity and substitutability phenomena in association with IT investment, however, the joint presence of national savings and IT creates the substitutability phenomenon across different frontiers. (v) In linking cross-country differences in the IT investments to stages of economic development, our complimentary qualitative analysis tends to conclude that the investments in IT in the advanced developed countries (e.g., G7) and some of the newly developed or emerging economies are likely needed to keep the pace with other competitors and maintain their status of economic development; and the IT investments in the Eastern European countries are necessary to reach the competitive level as well as to raise their economic-development level. (vi) An important policy implication is that policy makers must carefully utilize national characteristics while formulating IT investment strategies.     

Information technology tool use frequency in new product development: The effect of stage-specific use frequency on performance

Drawing from the Resource-based View of the firm and based on prior literature, we examine two organizational factors that top management can control (‘executive champion for IT’ and ‘formalized ROI for IT’) for enhancing information technology (IT) tool use during new product development (NPD). Further, we investigate the subsequent effects of IT tool use on NPD task proficiency and performance. Moreover, research on IT use in NPD has matured enough to suggest that the effect of IT tool use on outcomes should be examined with a decompositional approach in order to flesh out the nuances on consequences. Hence, adopting a phase-based approach, we examine the differences in the effects at three separate NPD stages: discovery, development, and commercialization. The model is empirically tested with data collected from large-sized Japanese firms. The results of structural equation modeling show that executive champion for IT positively influences tool usage in all three stages, and formalized ROI for IT has positive effect on enhancing NPD task proficiency in discovery and development. Further, IT tool use frequency enhances NPD task proficiency with varying effect sizes in all three stages, highest in discovery and lowest in commercialization. Finally, concurring with prior literature, task proficiency is found to affect NPD performance positively. Based on these findings, we discuss theoretical and managerial implications as well as provide specific suggestions for future research.     

Women and IT contracting work—a testing process

This paper explores the career and work experiences of a little researched group: highly skilled women IT contractors. It considers their reasons for entering the IT field, including the decision to become contractors. It demonstrates the complexity of power and influence of IT contractors and the resilience of the gender order in IT work.     

Union Members' Usage of IT

An important issue in assessing the potential benefits of information technology (IT) as a tool for increasing labor's effectiveness is union members' use of IT. Using 2003 Current Population Survey data, we examine the union members' IT and Internet usage at home and work. We find that union members are more intense users of IT at work than nonunionized employees and that high-intensity IT users constitute about one-third of the union sample.     

The role of information technology in strategic buyer–supplier relationships

Information technology (IT) has long been acknowledged as an integral part of inter-organizational business exchange. The extant research, however, tends to emphasize the focal company perspective and focuses on operational issues, perceiving IT and business relationships as separable. Through a qualitative dyadic case study, our study defines how IT is positioned with regard to various elements of a strategic buyer–supplier relationship and the respective actors' operational and managerial behaviors. The study defines the role of IT regarding the structural, action, and management layers of a relationship and shows how IT can be a strong element around which relationship management activities are implemented to improve the consistency and performance of the relationship. The study prepares the ground for further qualitative and quantitative research to enhance a holistic understanding on IT in relation to the structures and processes in inter-organizational contexts of business relationships and networks.     

IT competency and firm performance: is organizational learning a missing link?

Many companies have developed strategies that include investing heavily in information technology (IT) in order to enhance their performance. Yet, this investment pays off for some companies but not others. This study proposes that organization learning plays a significant role in determining the outcomes of IT. Drawing from resource theory and IT literature, the authors develop the concept of IT competency. Using structural equations modeling with data collected from managers in 271 manufacturing firms, they show that organizational learning plays a significant role in mediating the effects of IT competency on firm performance.

How Information Technology Assimilation Promotes Exploratory and Exploitative Innovation in the Small‐ and Medium‐Sized Firm Context: The Role of Contextual Ambidexterity and Knowledge Base

This research sheds new light on how information technology (IT) assimilation affects exploratory and exploitative innovation in the context of small‐ and medium‐sized firms (SMEs). This contextualization is important in establishing the boundary conditions for the theory, as well as generating specific managerial insights for SME managers. A sample of 248 U.K.‐based SMEs in the manufacturing industry demonstrates contextual ambidexterity (CA) mediates the relationship between IT assimilation and two types of innovation. This finding highlights that IT assimilation does not automatically promote innovation. Instead, IT assimilation represents a critical resource that enables the effective implementation of CA, which in turn affects innovation. This implies that SMEs cannot fully realize the potential of their IT assimilation and use it to enable innovation without implementing CA. Furthermore, this study differentiates between two different dimensions of knowledge base: knowledge breadth and knowledge depth. This study finds that knowledge breadth moderates the indirect IT assimilation–exploratory innovation relationship by influencing the effect of CA on exploratory innovation. Knowledge depth, on the other hand, moderates the indirect IT assimilation–exploitative innovation relationship by influencing the effect of CA on exploitative innovation. This finding implies that SMEs can benefit from their IT assimilation that enables them to engage in CA, which in turn allows them to perform innovation. However, it is apparent that the dimension of knowledge that SMEs hold internally can determine what types of innovation that they are able to perform.     

Information technology impacts on innovation

In this paper, we propose a model of Information Technology (IT) impacts on innovation. We do not intend to generalize a specific model of innovation. Rather, the objective here is to explain how IT can facilitate innovation in a work group. Review of literature suggests that innovative ability of a work group is dependent on the capabilities of the individuals/group, the structure of the work group or organization, and the group/organizational environments. To explore this conceptual model, data were collected from 136 users who used well-established information systems. The data supported that IT enhanced innovation significantly by augmenting individual/group capabilities through: 1) motivation support, 2) resource support, and 3) information support. Motivation support was shown to be the most important contributor of innovation. Group interaction variables, standardization, decentralization, and specialization, were shown to be positively related to innovation. However, the effect of group interaction was secondary in nature; the independent contributions to innovation of group interaction variables, controlling for other factors, were not significant. In addition, the data provided support that innovation was positively related to demand pull via motivation and resource support, and to technology push via information support.     

Do Social Media Tools Impact the Development Phase? An Exploratory Study

Over the past two decades, firms have increasingly adopted information technology (IT) tools and services to improve the new product development (NPD) process. Recently, social media tools and/or tools that include social networking features are being utilized to allow users both inside and outside the organization to easily communicate and collaboratively design, manage, and launch new products and services. Unfortunately, there is little empirical evidence to suggest what influence these new IT tools have on NPD performance. Through a project‐level, exploratory, empirical study, the impact of these new IT tools on the development phase of the NPD process is investigated. We find that the use of these new tools is significantly lower than the adoption of traditional IT tools such as e‐mail and computer‐aided‐design. Traditional tools have a significant, positive impact on NPD outcomes, including team collaboration, the concepts/prototypes generated, and management evaluation. Interestingly, new media tools such as project wikis and shared collaboration spaces also have a significant, positive impact on concepts/prototypes generated, and management evaluation. Surprisingly, social networking tools like weblogs and Twitter negatively impact management evaluation while having no impact on NPD team collaboration and concepts/prototypes generated. These results suggest that social networking tools in their current guise are not helpful to the NPD team and may in fact be distracting to innovation management during the development phase.     

Information technology and its changing roles to economic growth and productivity in Australia

In this paper we describe our investigation of the role of investment in information technology (IT) on economic output and productivity in Australia over a period of about four decades. The framework used in this paper is the aggregate production function, where IT capital is considered as a separate input of production along with non-IT capital and labour. The empirical results from the study indicate the evidence of robust technical progress in the Australian economy in the 1990s. IT capital had a significant impact on output, labour productivity and technical progress in the 1990s. In recent years, however, the contribution of IT capital on output and labour productivity has slowed down. Regaining the IT capital productivity therefore remains as a key challenge for Australia, especially in the context of greater IT investment in the future.     

Internetworked after-sales service

Firms, even ones in relatively heavy industries, seem to be moving in a direction in which information technology (IT) is becoming more and more integrated into their organizations. This paper describes a good, perhaps model, firm that appears to be getting better by recognizing IT per se as an actor in its after-sales organization. Both a smarter product and IT produced evolutionary changes in its after-sales operations. As the product becomes self-diagnostic, it is increasingly evident that the technology is an actual participant in the organization. These developments are interpreted in terms of internetworking concepts. Perhaps one outcome of this study will be to encourage leaders/managers to utilize some of the precepts of actor network theory (ANT) in their thinking.     

Outsourcing decision-making aspects considered by IT departments in Brazilian companies

The study of Information Technology (IT) outsourcing is relevant because companies are outsourcing their activities more than ever. An important IT outsourcing research area is the decision-making process. In other words, the comprehension of how companies decide about outsourcing their IT operations is relevant from research point of view. Therefore, the objective of this study is to understand the decision-making process used by Brazilian companies when outsourcing their IT operations. An analysis of the literature that refers to this subject showed that six aspects are usually considered by companies on the evaluation of IT outsourcing service alternatives. This research verified how these six aspects are considered by Brazilian companies on IT outsourcing decisions. The survey showed that Brazilian companies consider all the six aspects, but each of them has a different level of importance. The research also grouped the aspects according to their level of importance and interdependency, using factorial analysis to understand the logic behind IT outsourcing decision process.
