Reexamining the impact of information technology investment on productivity using regression tree and multivariate adaptive regression splines (MARS)

As health care costs increased significantly in the 1990s, investments in information technology (IT) in the health care industry have also increased continuously in order to improve the quality of patient care and to respond to government pressure to reduce costs. Several studies have investigated the impact of IT on productivity with mixed conclusions. In this paper, we revisit this issue and re-examine the impact of investments in IT on hospital productivity using two data mining techniques, which allowed us to explore interactions between the input variables as well as conditional impacts. The results of our study indicated that the relationship between IT investment and productivity is very complex. We found that the impact of IT investment is not uniform and the rate of IT impact varies contingent on the amounts invested in the IT Stock, Non-IT Labor, Non-IT Capital, and possibly time.     

Exploring the relationship between information technology investments and firm performance using regression splines analysis

Identifying the business value of information technology (IT) investments has been a major concern of managers and researchers. Various studies have addressed this issue but have provided contradictory results. Here, we explore the relationship between IT investments and firm performance using a relatively new technique, multivariate adaptive regression splines (MARS), and attempt to answer two questions: (1) do investments in IT have a positive impact on organizational productivity? and (2) for a given level of investment, what portion of the total should be invested in IT to maximize organizational productivity? Our results suggest that depending on the conditions that applied, an unbiased observer could either conclude that investments in IT has a positive statistically significant effect on productivity, or that there is a ‘productivity’ paradox. This suggests that the relationship between IT investments and organizational performance is much more complex than that found in some other studies. Our results could also provide guidance to managers who are responsible for determining the allocation of organizational resources.

Complementary Investment in Change Management and IT Investment Payoff

Measuring information technology payoff continues to be a challenge for organizations. Considering the impact of complementary investments on IT payoff has been proposed by recent studies. This paper examines the impact of one type of complementary investment on IT payoff: organizational change management initiatives to support IT implementation. The paper reports a case study of Cisco Systems' IT investment in an operating systems upgrade of over 34,000 computer systems in 117 countries. The findings of the exploratory case study indicate that planned communications and change management strategies developed by their Organizational Change Management group led to the smooth implementation of the upgrade process and contributed to the payoff from the IT investment, measured in terms of client satisfaction with the process and system and reduced cost and time to upgrade all systems. The findings were supported by pre- and post-implementation surveys of clients, analysis of the change management initiatives and their impact on the process, and comparison of actual and budgeted costs for the project.     

The transformational dimension in the realization of business value from information technology

Econometric studies have highlighted factors that appear to explain the differential effects of information technology (IT) on productivity at the firm level. Central to these explanations is the concept of organizational transformation; that value realization from IT depends on time-consuming investments in organizational change and results in new, often intangible, organizational assets. The aim of this study was to further investigate the concept of IT-enabled organizational transformation as a component of the value realized from IT at the firm level. Survey data was analyzed from respondents from 1050 businesses of varying sizes and across industries. Transformational benefits were found to exist as a distinct benefit category and to be closely related to other forms of IT-generated business benefits. They were also an important component of overall IT business value. Qualitative data illustrated these findings and pointed to possible complex causal relationships in the generation of IT value. The findings have implications for models of IT business value generation and for managerial practice.     

The Impact of Information Technology Investment on Enterprise Performance: A Case Study

Investment in information technology is steadily increasing, but many organizations find it difficult to formally assess the value of IT investments because the latter are often incorporated into broad management initiatives. the authors believe that the results of the research study reported on here can help firms to develop a better understanding of the dynamic relationship between IT investment and performance at both the firm and industry levels of analysis. This study clearly demonstrates the importance of adopting an organizational change perspective when assessing the impact of IT investment on firm performance.     

A study of the impact of information technology on firm performance: a flexible production function approach

Most previous studies of the impact of information technology (IT) on firm performance have relied on the Cobb–Douglas production function, which makes unrealistic assumptions. These include assuming that (1) the scale elasticity, i.e. returns to scale, is constant throughout the entire output range; (2) the elasticity of substitution between inputs is one, whereas it can be anywhere from zero to infinity in practice; and (3) there are no complex interrelationships between inputs, i.e. no squared or product terms. The translog production function (used in two previous studies) does not make these assumptions and is therefore more accurate. However, the two previous studies found no significant difference between the two. This research has extended previous work on the impact of IT investments by providing more accurate results in some areas and new findings in others. IT's importance is shown to be much greater than previously thought. The translog function is used to demonstrate that the productivity paradox does not hold (i.e. both IT labor and capital indeed have a significant impact on firm revenues), but with considerably different results, i.e. the impact of IT is markedly more significant than that obtained from the Cobb–Douglas. Another interesting finding is that of scale elasticity. Our results show that this is less than 1, implying decreasing returns to scale of output. Finally, the substitutability between inputs was determined, which is not possible with the Cobb–Douglas. It was found that the partial elasticities of substitution for IT labor with IT capital and non-IT labor were quite substantial.     

Information Systems Offshore Outsourcing: An Exploratory Study of Motivations and Risks in Large Spanish Firms

Prior research has documented that IT investment increases market returns. Economic theories predict such returns to be recognized in accounting profitability; this relationship remains ambiguous in prior literature. We reexamine the relationship between IT investment and firm profitability. Our approach is unique in that we examine complementarities between distinct IT components. We document that a firm’s investments in IT components exhibit different impacts on its profitability conditional on the level of investments in complementary components.     

A hybrid performance measure system for e-business investments in high-tech manufacturing: An empirical study

For over a decade, empirical studies on the organizational performance of IT investment have been far from conclusive, and one major issue that has led to an ongoing debate is whether inadequate methods are applied in measuring IT values. Traditional measures have primarily been financial: return on investment and return on sales. Researchers have suggested a need to use other measures, although there has been little agreement on which precisely to use. Moreover, empirical studies showed limitations in using only a single organization-level measure, whereas a more complete assessment could involve measures from several levels. In addition, benefits from IT investments are normally realized over time. This study used an integrative assessment framework with a three-level structure of organizational hierarchy: corporate strategies, manufacturing decisions, and operational activities, along with a time-lag effect. Different levels of performance measures were examined over different time periods. The framework was verified by survey data. Our results indicated that time tag had positive impact on the performance measures of corporate strategies and that they were significantly correlated with operational activities.     

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.     

Causality in the alignment of information technology and business strategy

The need for a link between information technology (IT) use and organizational strategy has been identified and discussed for a number of years. The thrust of this work argues that the motives for investment in IT should derive from firm objectives and, more particularly, from the strategic plan which the organization wishes to pursue. This paper argues that, often, mere lip service is paid to the strategic nature of IT. Further, strategy justification has become a tool for securing investment in IT by circumventing established organizational policy on investments. Many IT investments labelled ‘strategic’ appear to be operational in nature. This paper discusses the nature and evaluation of strategy and relates it to the literature on IT as a strategic tool. The extent to which the relationship between IT and strategy has altered over recent years is subsequently investigated. The implementation process is investigated and evidence of IT investment activities and the returns available to investing organizations are reviewed. The paper argues that there are a number of alternative views on the IT-strategy relationship, some of which are organizationally detrimental.     

Closing the loop: Empirical evidence for a positive feedback model of IT business value creation

Researchers have established that information technology (IT) can improve firms’ productivity. Whether improved productivity leads to additional investment in IT, however, remains largely uninvestigated. In this paper, we consider whether the relationship between productivity and subsequent IT investment might be positive, negative, or ad hoc, and hypothesize that this relationship is positive. We analyze seven years of panel data from 1236 healthcare firms and present empirical evidence supporting our hypothesis. When our finding is combined with extant research, it becomes reasonable to propose that unidirectional causality does not fully describe the process of IT business value creation. Instead, we argue that existing static models of IT business value with unidirectional causality can be recast as dynamic models that explicitly incorporate multiple time periods and a positive feedback relationship to more accurately capture the complexity of this process. The creation of IT business value can thus be understood as a positive feedback model where IT investment in a given time period builds the stock of IT inputs, where those IT inputs then impact productivity, and where productivity leads to IT investment in a future time period, beginning the cycle anew.     

Balancing exploration and exploitation of IT resources: the influence of Digital Business Intensity on perceived organizational performance

Facing a barrage of novel information technology (IT), organizations must invest on the basis of the impact of IT capabilities on the organization’s performance. This research extends Bharadwaj’s (MIS Quarterly 169–196, 2000) resource-based view of the relationship between IT capability and performance by introducing both the mediating and moderating effects of Digital Business Intensity (DBI). Empirical data collected from CIO’s from US firms reveal that although IT capability positively influences organizational performance, this relationship may differ in strength at different levels of DBI. Our study also finds that IT capability is important in determining DBI, which in turn influences organizational performance. Findings highlight tensions between DBI exploration and IT capabilities exploitation. Results also suggest that companies that leverage their existing IT capabilities to drive DBI are more adept at securing performance returns. However, when DBI investments do not complement existing IT capabilities, DBI appears to dampen performance, further accentuated for high-DBI firms.     

Impact of information technology investment: An empirical assessment

Assessing the impact of information technology (IT) investment on organizational performance has been found to be problematic. Past studies of relationships between information technology investment and organizational performance has generally produced mixed, inconclusive, and even confusing results. The research described here attempts to demonstrate the impact of IT investment by investigating relationships between sets of IT investment measures and organizational performance measures. The results reveal positive and significant relationships between certain of the IT investment measures and organizational performance measures used in the study, indicating that organizations with greater levels of IT investment also had higher performance, as measured by return on investment, return on sales, sales per employee, sales by total assets, and market value to book value.     

Evaluation of information technology investment: a data envelopment analysis approach

The increasing use of information technology (IT) has resulted in a need for evaluating the productivity impacts of IT. The contemporary IT evaluation approach has focused on return on investment and return on management. IT investment has impacts on different stages of business operations. For example, in the banking industry, IT plays a key role in effectively generating (i) funds from the customer in the forms of deposits and then (ii) profits by using deposits as investment funds. Existing approaches based upon data envelopment analysis (DEA) only measure the IT efficiency or impact on one specific stage when a multi-stage business process is present. A detailed model is needed to characterize the impact of IT on each stage of the business operation. The current paper develops a DEA non-linear programming model to evaluate the impact of IT on multiple stages along with information on how to distribute the IT-related resources so that the efficiency is maximized. It is shown that this non-linear program can be treated as a parametric linear program. It is also shown that if there is only one intermediate measure, then the non-linear DEA model becomes a linear program. Our approach is illustrated with an example taken from previous studies.     

Understanding the impact of business cases on IT investment decisions: An analysis of municipal e-government projects

This study synthesizes the extant literature to derive an integrative developmental framework for IT business cases that can be applied to diagnose the feasibility of technological investments. We then construct a theoretical model that postulates the impact of IT business case elements on the initial cost estimates of technological investments. Subsequently, our theoretical model is subjected to empirical validation through content analysis of IT business cases developed for municipal e-government projects. Findings indicate that the richness of the richness of business cases translates to more initial costs being identified in technological investments, thereby conserving resources for the organization through informed investment decisions.     

Exploring the relationships between IT competence,innovation capacity and organizational agility

Business environments today are characterized as being very dynamic and hyper competitive. Organizations in these environments have to be agile in order to adapt their strategies and actions to be successful. While it is recognized that information technology can enable firms to be agile, there is a limited understanding of the mechanisms through and the contexts in which Information Technology (IT) enhances agility. This study examines two key antecedents of organizational agility, namely the IT competence of a firm and its innovation capacity and, examine their independent and joint effects on agility. We test our model using data collected from large firms in the US. The results provide strong support for our model. We found that firms with superior IS capabilities coupled with an aggressive IT investment orientation create digital platforms that enable them to be agile. We also found that the innovation capacity of the firm has a positive relationship with organizational agility and that firms with higher innovation capacity are better able to leverage their digital platforms to enhance agility. Our results indicate that organizational agility has a strong positive impact of firm performance. We interpret and discuss these results and their theoretical and practical implications.     

Maximizing the positive influence of IT for improving organizational performance

In the analysis of whether information technology (IT) has an impact on organizational performance, focus is usually placed on the relationship between an organization’s investments in IT and that organization’s performance. Therefore, it is standard to devote special attention to the size and complexity of the organization, to the investments in other organizational resources that may affect the performance of IT, and to the manner in which the two variables are measured. However, one area that has not been well explored is the manner in which the relationship between investments in IT and organizational performance develops. In this article, we show empirically that the planning and management of IT influence the organization’s endowment of resources (physical and human), which consequently has positive effects on each of the IT-related areas usually found in organizations (applications, reliable and secure systems and communications, and training and support). In turn, the functioning of these areas influences the impact of IT on the organization, which then has positive effects on organizational performance. We have used data corresponding to IT management in Spanish universities, as well as independent rankings that are useful for evaluating their performance.     

Modeling the business value of information technology

Modeling and measurement issues have been considered the heart of information technology (IT) productivity paradox problem. By collecting data from seven mortgage firms, this research attempts to shed light on the causal relationships and complementarity properties among IT and performance variables. The result is a multi-level business value model that connects the use of IT to a firm’s profit. It is concluded that although there exists a causal relationship between IT and profit, this relationship is indirect and complex. Due to the complementary nature of the relationships, such a complexity is not reducible. All complementary factors must be in favorable conditions for a positive return of IT investments.     

The impact of information and communication technology on skilled labor and organization types

Information and Communication Technology (ICT) affects the global economy and the business world enormously. In particular, the impact of ICT on work organization has been in the spotlight since the widespread introduction of computerized systems two decades ago. However, the relationship between ICT and organizational factors has not been indentified clearly. This study aims to investigate possible complementary relationships between ICT diffusion and organizational factors such as: labor, firm organization, product differentiation and the demand for skilled labor. Utilizing detailed firm-level data in Korea, this research scrutinizes whether the relationship among the organizational factors in Korean firms is different from that of other technologically advanced countries. The results show that ICT demand is complementary to investment in human capital and product differentiation, but not to autonomous organizations. ICT is also found to contribute to productivity and profitability in addition to its effects on these relationships. The results do not show any synergic effect with other factors, however. Investment in ICT should be considered with other organizational factors with attention paid to synergistic effects. The implications could help practitioners as well as academicians in investing in ICT and in studying ICT investment respectively.
